Introduction to Sand-Lined Pipe Products
Sand-lined pipes are new composite pipes made of resin as the matrix material, glass fibers and their products as the reinforcing materials, and quartz sand as the filling material. They are widely used in large-diameter water supply and drainage, industrial fluid transportation, agricultural irrigation and other fields.
Product Structure
Anti-Seepage Layer (Lining Layer)
Composed of E-type chopped fibers rich in resin. It has strong anti-seepage ability and can ensure no leakage of the product.
Structural Layer
This layer is composed of materials with different functions. It uses resin with excellent mechanical strength as the matrix, and uses circumferential winding fibers (to enhance circumferential tensile strength, axial tensile strength and external load resistance), E-type chopped yarn and selected quartz sand as reinforcing materials (the content and distribution of materials are based on computer design under service conditions).
Outer Protective Layer
It has a resin-rich layer and an anti-ultraviolet formula, which can effectively prevent or delay natural aging and corrosion of soil chemical media
Product Characteristics
Stable Performance: Under the control of a programmable controller, raw materials can be put in with precise quantity, the winding speed is balanced and stable, and online detection and continuous feedback tracking are supplemented to ensure the stable and reliable quality of the pipe from beginning to end.
Excellent Waterproof Performance: The flat steel strip induction heating and infrared multi-point temperature control are adopted. The good impregnation of the glass fiber surface mat and resin makes the lining layer have high corrosion resistance and anti-seepage performance
Good Sealing Performance: Rubber ring sealing is adopted, and the highly sealed sleeve-type joint ensures no leakage. After the pipe installation is completed, the sealing test can be carried out in accordance with the relevant requirements of BS8010 or GB/T50268.
Low Transportation and Installation Costs: Glass fiber reinforced plastic sand-lined pipes are light in weight, so pipes of different diameters can be easily nested, which is very convenient for transportation; the inner and outer diameter sizes of the pipes are stable, and the inner and outer surfaces are smooth and flat, making the installation simple, thus greatly reducing transportation costs, pipe laying costs, connection costs, installation costs and trench excavation costs.
Product Advantages
01 Good Corrosion Resistance
Resins with cross-linked structures have high corrosion resistance. FRP sand-lined pipes further improve the surface corrosion resistance through circumferential structural design. No anti-corrosion treatment is required for the inner and outer walls of the pipes.
02 Light Weight and High Strength
Light specific gravity: The weight of FRP sand-lined pipes is only 1/4 of that of steel with the same volume.
High strength: The tensile strength in the fiber direction can reach 1000MPa, which is higher than that of Q235 steel.
Low transportation cost: Low requirements for hoisting equipment.
03 Good Designability
It can be conveniently and quickly designed into various non-standard types, especially suitable for continuous variable diameters, non-standard elbows and complex curved surface structures, which are difficult to be realized by other pipes.
04 Smi-oth ine Wall andand
Low inner wall roughness coefficient: The roughness coefficient of FRP pipes is 0.009, while that of concrete pipes is 0.014, which is 56% higher than that of FRP pipes.
Strong transportation capacity: Under the same hydraulic gradient, the flow rate of FRP pipes is 1.56 times that of ductile iron pipes of the same diameter.
Low pipe diameter requirement: Under the same hydraulic gradient, the diameter of FRP pipes required to transport the same flow rate is only 84.7% of that of ductile iron pipes.
High Reliability 05
Both the pipe and the pipe joints have passed the pressure test of the pressure testing machine to meet the relevant requirements. The double O-ring structure has a pressure test interface directly, which can test the connection reliability between each pipe section one by one.
06
It can withstand extreme temperature environments and be used stably for a long time, and still has good toughness and strength at -40°C.
Easy Construction 07
Light in weight and high in strength, easy to transport and hoist; adopts socket-type double O-ring joints, which is simple and fast to install

Introduction to Composite Material Internal Floating Roofs (for Vertical Storage Tanks)
Integrated Unitization
Complete Composite Material Integrated Molding with High Reliability:
● Relying on the unique thermosetting molding technology of composite materials, the reliable connection between modules, as well as between honeycomb materials and upper and lower plate panels is ensured.
It solves the hidden danger that the spliced floating roof may be easy to loosen and fail at the joints.
• It reduces emissions from the source and eliminates VOCs (Volatile Organic Compounds) emissions at the splicing gaps.
Unitized Liquid-Tight Structure with High Safety:
• Hundreds of unit modules composing the floating roof are all independent liquid-tight structures, and these units are composed of hundreds of thousands of honeycomb structures that are both independent and closely connected.
• In case of an accident, the liquid inflow caused by any single-point leakage on the floating roof will be confined to the honeycomb unit.
Corrosion Resistance
Corrosion Resistance:
The floating roof is made of full composite materials, which will not be oxidized like metal. It can solve the problem that metal floating roofs are easy to be corroded, and at the same time ensure that the liquid chemical products in the storage tank are far away from rust and other pollutants.
Good Medium Compatibility:
•It can meet the storage requirements of most liquid chemical products. For special application occasions, the composite material formula can be adjusted according to specific needs.
High Availability
High Buoyancy:
The additional buoyancy load can reach 36kg/m².
Low Section:
The thickness of the conventional plate body is only 80-100mm, which reduces the volume occupation of the storage tank and improves the utilization rate of the storage tank.
High Strength:
It can bear a concentrated load of 917kN/0.1m², which is hundreds of times higher than the national standard requirement.
High Safety Factor:
When 12.5% of the floating roof support fails, the deformation of the floating roof is only 7% of the allowable condition, and the safety factor exceeds 14.
It is maintenance-free for life, with a service life of more than 20 years.
The main body of the floating roof is a honeycomb sandwich structure made of full composite materials. The prefabricated modules in the factory are integrally formed by thermosetting connection technology, with no splicing seams and full liquid contact. It integrates multiple advantages such as safety, environmental protection, corrosion resistance, fire resistance and explosion resistance.
Intrinsic Safety
Adopting Vacuum Infusion Technology to Ensure the Sealing and Consistency of the Floating Roof:
The quality of modules is crucial. Most of the new floating roofs adopt a modular design. Once the modules leak, the stored liquid will enter the floating roof modules, which will become a major hazard source (Note: many accidents in the industry are related to liquid leakage of floating roof modules).
The vacuum infusion process technology is creatively used to produce the modules composing the floating roof, so as to ensure the long-term sealing and consistency of the floating roof modules.
Overall Air Tightness Test to Ensure the Stable Overall Structure of the Floating Roof:
A unique patented structure is used to test the air tightness of the floating roof splicing. Combined with the air tightness test of the annular seal, a closed-loop overall air tightness test is formed to ensure the reliable sealing of the overall structure of the floating roof.
Adopting Full Plate Resistance Reduction Process to Ensure the Static Electricity Safety of the Floating Roof:
A unique full plate resistance reduction process is adopted to ensure that the overall resistivity of the floating roof is between 10ªΩ·m, which meets the requirements of GB 12158 for electrostatic sub-conductors.
● The surface wear and local damage of the floating roof do not affect the static electricity discharge.
Fire Resistance and Explosion Resistance
Fire Retardancy:
● The floating roof as a whole meets the requirements of relevant standards such as BS476 Part7, ASTM E84, NFPA and UFGS, and the fire resistance time of the floating roof exceeds 2 hours.
● In 2009, the floating roof passed the fire resistance test certified by SGS, TÜV and LastFire.
● In 2021, the full composite material floating roof passed the fire resistance evaluation in the "Evaluation Outline for Fire Resistance Performance of New High-Efficiency Floating Roofs" hosted by Tianjin Fire Research Institute.
Overall Explosion Resistance:
The floating roof has been proved by sufficient simulation experiments and simulation calculations that it can withstand a transient pressure of more than 1.5MPa in case of flash explosion, which is safe and reliable.
The floating roof has passed the simulated explosion test verification of Dalian University of Technology.
● It has carried out research on the anti-explosion evaluation system of new high-efficiency floating roofs in cooperation with China University of Petroleum, Northeast Petroleum University and the Logistics College of the Chinese People's Liberation Army.
Easy Installation
It has flexible installation, short construction period and high efficiency; low cost, no fire work and no electricity work.
FRP Chimney and Cooling Tower Series
Product Introduction
In the "chimney and cooling tower integration" project, the flue made of FRP has strong corrosion resistance, so the flue gas after desulfurization does not need to be heated above the dew point, which can save investment and is an economical choice. More importantly, the "chimney and cooling tower integration" technology can improve the lifting height of the clean flue gas after desulfurization, which is conducive to meeting environmental protection requirements and will be an inevitable development direction of domestic thermal power plants in the future.
Specification: DN10-25000mm
Temperature Resistance: Below 220°C
"Chimney and cooling tower integration" means that the waste gas discharge of the power plant is no longer discharged into the atmosphere through the chimney, but is transported to the hyperbolic cooling tower through the flue. The flue gas after desulfurization is transported to the high altitude through the flue inside the tower, and the flue and the cooling tower are integrated to form a waste gas discharge system.
The reason why FRP is used to make the flue in the "chimney and cooling tower integration" project is that it has excellent corrosion resistance and durability, and a long service life of up to 30 years, which saves costs and is consistent with the life cycle of the thermal power plant. It avoids the economic loss and trouble caused by shutdown due to pipe replacement and saves the anti-corrosion cost of the flue.
The use of FRP to make the flue in the "chimney and cooling tower integration" project has great environmental significance. The "chimney and cooling tower integration" technology was first developed by Germany, and is currently only applied in 4 European countries including Germany. The waste gas purification rate reaches 97.5% when the "chimney and cooling tower integration" is used for waste gas discharge, and especially the ground concentration of waste gas is better than that of chimney discharge. The discharge height of the chimney is about 300 meters, while that of the "chimney and cooling tower integration" is 500 meters, which increases the diffusion range of the treated waste gas. The ground concentration of carbides can be reduced to below 400mg/m³.
FRP flues can also reduce the power consumption and operation cost of thermal power plant equipment. They eliminate the traditional chimney and save civil engineering costs. Since the cooling tower uses water vapor to take away the waste gas, the booster fan is omitted, which saves equipment costs and fan operation power consumption. At the same time, FRP pipes are light in weight and do not need support brackets, which saves the construction cost of this part.
Product Application
It is mainly used in the "chimney and cooling tower integration" project of power plants, and also used in the treatment of waste gas in environmental protection equipment

It can be used after being hoisted in place and leveled. The installation is simple and easy to adjust, which can greatly shorten the installation period. The installation environment is good, and there is no toxic dust caused by on-site grinding of traditional FRP linings, which is more environmentally friendly.
Improved Product Quality: The electrolytic cell features overall anti-corrosion properties, addressing issues such as undetected damage in other materials that lead to electrolyte leakage, calcium sulfate contamination, and compromised cathode plate quality. This design thereby reduces corrosion of cell attachments caused by electrolyte leakage.
Purified Environment and Reduced Cleaning Water Consumption: The traditional FRP lining needs to be replaced and remade after a few years. The replaced FRP is non-degradable and will adhere to the electrolyte causing environmental pollution and loss of valuable metals. The optimized design of the electrolytic cell has arc-shaped corners, which requires less water and shorter cleaning time when cleaning the cell.
Improved Current Efficiency: The reinforcing ribs of the structural layer do not use steel bars, so there is no eddy current generated on the cell wall under the condition of high-current electrolysis. In addition, due to its good insulation performance, the current efficiency can also be improved.
Product Application
According to the applicable metal types and production processes, it can be divided into copper electrolytic cells, copper electrowinning cells, zinc electrowinning cells, nickel electrolytic cells, cobalt electrolytic cells, lead electrolytic cells, manganese electrolytic cells, copper removal cells, nickel solution preparation cells, etc.
FRP Grating Products
Product Introduction
The density of FRP gratings is about 1.8, which is only 1/4 of that of steel and 1/3 lighter than that of aluminum. When using gratings, the weight of the components is greatly reduced, and the use of hoisting equipment can be avoided, which is both economical and convenient.
With a long service life (generally up to 20 years) and no maintenance required, its comprehensive economic benefits are much better than those of carbon steel.
It has good insulation and flame retardancy. FRP gratings used in flammable and explosive environments can reduce accidents. FRP gratings have a certain elasticity, which makes personnel working on them for a long time feel comfortable. Especially when used as platforms, they can reduce the tension of workers' legs and backs, increase work comfort, and thus greatly improve work efficiency.
FRP gratings can be colored arbitrarily according to customer requirements, usually gray, grass green, blue and yellow. The color is a color paste miscible with resin, which is mixed into the resin and formed integrally. The color is consistent inside and outside and not easy to fade. Choosing brightly colored gratings will change the traditional black situation in anti-corrosion environments and add color to modern enterprises.
Product Application
It is widely used in operation platforms, equipment platforms, drilling platforms, floors, stair treads, ramps, bridge walkways, railway crossing walkways, truck top walkways, pedestrian overpasses, fences, equipment safety fences, airport lighting fences, scaffolding, filter grids, ventilation grids, decorative gratings, trapdoors, washing racks, corrosion-resistant shelves, trench covers, ship decks and mooring docks.

Composite Materials Underground Storage Tank Introduction
Feature 1: Corrosion Resistance of Both Inner and Outer Layers
• Only high-quality raw materials are used to ensure that both the inner and outer layers have excellent corrosion resistance.
• They are non-metallic, no expensive cathodic protection is required, and the maintenance cycle is long.
Far away from microbial corrosion and rust, and the fuel products are cleaner.
Feature 2: Strong Structure and High Comprehensive Strength
• 3D Glass Fiber Technology: The middle layer uses 3D glass fiber fabrics, which are similar to columns in construction, connecting the inner and outer walls, making the inner layer, middle layer and outer layer of the fuel tank an integral whole. When external force is applied, the whole body bears the force together, which increases the structural thickness and comprehensive strength of the fuel tank.
Unique Negative Mold Forming Process: It ensures that the reinforcing ribs are integrally formed with the outer wall of the tank, essentially solving the problem that the reinforcing ribs may be separated from the tank body in the buried environment. The thickness, spacing, width and height of the fuel tank reinforcing ribs are calculated strictly to ensure the overall strength of the fuel tank from the structure. The burial depth can reach 2.1 meters.
• Ground Anchor Strap and Backfill System: In the installation of the fuel tank, ground anchors and straps are used, and the whole is backfilled with ordinary gravel, so that the fuel tank and the backfilled ordinary gravel form an integral anti-floating and pressure-bearing system.
Feature 3: Direct Burial Under the Lane
• It can be directly buried under the lane without the need to build a pressure-bearing pool, and the construction period is short.
•More and more gas stations adopt the design under the lane, which saves more costs.
FRP double-wall buried fuel tanks are mainly used for fuel storage in gas stations. Both the inner and outer layers are made of FRP composite materials, belonging to FF-type double-wall tanks. The middle layer of FRP double-wall buried fuel tanks adopts 3D composite material technology and reinforcing ribs integrally formed with the outer wall. With the adoption of these two technologies, combined with excellent design and production technology, the buried fuel tanks have the following technical features:
Feature 4: All-Weather and All-Round System Leak Detection
• Compatible with Level I or Level Il Leak Detection. The fuel tank is compatible with Level I vacuum leak detection and Il liquid medium leak detection, which can realize all-round monitoring of the fuel tank.
•Not all double-wall fuel tanks can use the liquid medium method for leak detection: 1. Both inner and outer layers are not corroded by the leak detection liquid medium. 2. The adoption of 3D composite material technology ensures that the leak detection liquid can penetrate 360° in the 3.5mm middle layer.
Feature 5: Easy Installation and Short Construction Period
• Prefabricated ground anchors are used, and there is no need to lay a concrete foundation for the fuel tank.
•It is light in weight and easy to hoist. The construction is assembled in modules, and the installation is simpler.
