PIPE CLASSIFICATION AND INSTALLATION

KEY POINTS

Thin-walled

stainless steel pipe

According to different diameters of steel pipes, stainless

steel strips with wall thickness ≥ 0.8-4.0mm are formed by

pipe making equipment, fused by automatic tungsten inert

gas arc welding (GTAW for short), and welded according

to the requirements of fluid delivery pipelines to make

stainless steel pipes.

Double-clip

connection method

Applicable to the connection of thin-walled stainless

steel pipes with nominal sizes of DN15-DN100. It is a

double-clip connection with extended edges. The shape

of DN15-DN100 after crimping is hexagonal. Groove connection

connection

Double crimping

connection method

Double crimping is a mechanical connection method. Its sealing

principle is to insert the stainless steel pipe into the pipe fitting with

a sealing ring, and use a special tool to crimp the interface position. The end of the pipe fitting produces concentric contraction to seal. The crimping position of the DN15-DN50 pipe and pipe fitting

produces hexagonal deformation, and the crimping shape of the DN65-DN100 pipe and pipe fitting is round, which plays a role in

the connection. Groove connection

method

Groove is a mechanical connection method. Put the O-ring

on the end of a grooved steel pipe. Insert another grooved steel

pipe into the O-ring, and rotate the O-ring so that it is located in

the middle of the interface. Install the upper and lower clamps on

the outside of the O-ring, and send the convex edge of the clamp

into the groove. Press the upper and lower clamp ears tightly. At

the position of the clamp screw hole, bolt and tighten the nuts

evenly and alternately to achieve a sealing effect. Welding connection

Welding connection installationproceduresThe welding connection method is argon arc welding, referred to as TIG. The argon gas layer suppliedbytheweldingtorch protects the heated welding area, so that the molten pool area and the tungsten electrode are not pollutedandoxidizedbythe air. The heat of the arc is used to weld the weld. The adjacent weldment or filler metal is melted and connectedtogetherasthe weld metal solidifies. Cutting the pipe: Use a professional

pipe cutter to cut it to the requiredlength, and keep the pipe end vertical.

Assembly: Insert the stainless steel pipe into the

socket of the fitting.

Deburring: Use a special chamferingtool to remove burrs inside andoutside the pipe end.

Welding: According to the welding technical

parameters, adjust the power supply tothelowest current possible for welding

Socke t we lding inst a ll a tion proc e ss

1. Marking and cutting (Figure 1)

According to the required pipe size, the cutting of thin-walled stainless steel pipes should be done in a non- significantly heated cutting method. The cutting tool should be a special electric pipe cutter, manual pipe cutter

or manual pipe cutter for marking and cutting When cutting, pay attention to keeping the cutting port

perpendicular to the horizontal plane of the pipe to ensure that the subsequent pipe and pipe fittings are in place. If the above special cutting tools are not available on the construction site, a grinding wheel sawcan be usedfor cutting, but the following conditions must be met:

① Use a grinding wheel saw that does not contain iron;

② The grinding wheel saw should be used exclusively for cutting stainless steel pipes and should not be usedfor cutting other metal pipes. 2. Deburring (Figure 2)

After cutting, pay special attention to using special tools (chamfers, files, etc.) to completely remove theinternal and external burrs of the pipe end and wipe the dirt inside the pipe clean. Otherwise, when thesubsequent pipeline is installed and put into use, the burrs left in the pipe will block the discharge of dirt. Theaccumulation of dirt will cause the chloride ions to exceed the standard and destroy the passivation filmon thesurface of the stainless steel product, thereby causing corrosion and leakage. (Water leakage case: burrs werenot removed, resulting in pitting corrosion, see the figure below)

3 Assembly (Figure 3)

Insert the stainless steel pipe into the socket of the pipe fitting. Before insertion, make sure that there is nocement, mortar, grease, paint or other debris adhering to the end of the pipe (fitting). After cleaning the end of

the pipe fitting, insert the stainless steel pipe into the socket of the pipe fitting and press against the bottomof

the socket.

30% not welded through

Afterthe current is adjusted, the socket end ofthe pipe is welded in a ring. The principle oflow current and high speedshouldbe adopted in the welding process. The molten pool metal is not allowed to penetrate the inner wall ofthe pipe, and the pipeshouldbe kept 30% unwelded. In addition, the heat input to the pipe should be minimized during welding, because during the weldingprocess of austenitic stainlesssteel, if itstays at 450-850℃ for a long time, chromium depletion will formon the austenitegrainboundary, which is easy to cause intergranular corrosion.

2. Beveling (Figure 3)

In order to achieve the required mechanical strength (including tensile strength, torsion resistance, etc.), thebutt

joints above 3mm need to be beveled, and the bevel angle is required to be 60-80 degrees. 3. Deburring (Figure 3)

After cutting, use a file to completely remove the burrs on the pipe end, and wipe the dirt inside the pipeclean. Otherwise, when the subsequent pipeline is put into use, the burrs left in the pipe will block the dischargeof dirt. The accumulation of dirt will cause excessive chloride ions and destroy the passivation filmon the surfaceofstainless steel products, thereby causing corrosion and leakage. Prevent iron tools fromknocking onstainlesssteel pipes (parts). 4. Steel pipe tack welding (Figure 4)

Clean up the debris and grease on both sides of the welded part, and then symmetrically spot weldthepipefittings at 6-8 points. During tack welding, the axis of the pipe fittings and the pipe should not be offset, theouter wall of the pipe should be flush, and the butt gap should not be greater than 2mm. Welding (Figure 5)

5. When butt welding the pipeline, the inner wall of the pipe should be protected by argon or nitrogen. Thealloycomposition of the selected welding wire metal material should not be lower than that of the base material, andat least one grade higher to compensate for the dilution or burning of the base material. After welding, theweldtempering color should be mechanically polished or pickled and passivated. Note the process:

1 When the welding process of steel with a thickness of more than 40mm requires multiple passes, argonarcwelding should be used for the base and manual arc welding for the cover. (Use stainless steel weldingrods). 2. The minimum purity requirement of argon gas used for welding is 99.96%. If the purity of argon gas doesnot

meet the requirement, forced use will not only affect the protection of the molten metal, but also easilycausethe weld to oxidize, produce defects such as pores, reduce the mechanical properties and corrosion resistanceofthe joint, and thus destroy the performance of stainless steel products.

Installation tutorial of double clampconnection method

Double clamp connection is a mechanical connection method. Itssealing principle is to insert the stainless steel pipe intothepipe fitting with a sealing ring, and use special tools to crimp the joint position. The end of the pipe fitting produces concentriccontraction to play a sealing role. The shape of the DN15-DN50 pipe and pipe fitting position produces hexagonal deformation, andthe shape of the DN65-DN100 pipe and pipe fitting isround, which plays a role in the connection.

Create a peaceful life Fujian Shengdatong Energy Saving TechnologyCo., Ltd.Double clamp installation process

1. Cutting pipe (Figure 1)

According to the required pipe size, the cutting of thin-walled stainless steel pipes should be done in a waythat

does not significantly increase the temperature. The cutting tool should be a special electric pipe cutter, manual

pipe cutter or manual pipe cutter for marking and cutting. Do not use too much force when cutting toprevent

the stainless steel pipe from losing its roundness. Pay attention to keeping the cutting mouth perpendicular tothe horizontal plane of the pipe, and the cutting mouth should not have elliptical and burr phenomena toensurethat the subsequent pipe and pipe fittings are inserted in place. Otherwise, the sealing ring will be damagedduring the insertion process and cause leakage. If the above special cutting tools are not availableontheconstruction site, a grinding wheel saw can be used for cutting, but the following conditions must be met

① Use a grinding wheel saw that does not contain iron;

② The grinding wheel saw should be used exclusively for cutting stainless steel pipes and should not beusedfor cutting other metal pipes. 2. Deburring (Figure 2)

After cutting, pay special attention to using special tools (chamfers, files, etc) to completely removetheinternal and external burrs of the pipe end and wipe the dirt inside the pipe clean. Otherwise, when the pipelineis installed and put into use, the burrs left in the pipe will block the discharge of dirt. The accumulationof dirt

will cause the chloride ions to exceed the standard and destroy the passivation filmon the surfaceof thestainless steel product, thus causing corrosion and leakage. (Leakage case: burrs were not removed, resultinginpitting corrosion, see the figure below)

3. Marking and marking (Figure 3)

To ensure that the steel pipe is fully inserted into the pipe body, the insertion length must be marked and markedonthe stainless steel pipe to ensure the insertion length. Otherwise, the stainless steel pipe may not be inserted properly, resulting in reduced joint performance and leakage. 4. Inserting the stainless steel pipe (Figure 4)

Before inserting the stainless steel pipe into the pipe fitting, it is necessary to confirm that the sealing ring is correctlyinstalled in the U-shaped groove of the pipe fitting. The pipe mouth must not be elliptical, and there must be nosandor debris at the end. The end of the stainless steel pipe of the pipe fitting should be kept clean. When inserting, it

should be inserted into the pipe fitting body slowly and straightly and ensure that the insertion length is at the markedposition. When inserting, it should be inserted into the pipe fitting body slowly and straightly. Otherwise, the stainlesssteel pipe will be inserted obliquely and the sealing ring will be damaged or fall off. If the insertion is too tight, youcan wet the stainless steel pipe with water, but you must not use lubricating grease to prevent the grease fromreducingthe life of the sealing ring. 5. Selection of crimping tools

The installation of thin-walled stainless steel crimping pipes must be installed using the crimping tools providedbythe manufacturer to ensure the safety and reliability of the crimping joint connection. 6. Crimping (Figure 5)

Crimping of DN15-50

The tool should be cleaned before crimping, the groove of the crimping die should be close to the arc convexpart ofthe pipe fitting, and the tool jaws should be perpendicular to the axis of the stainless steel pipe. Before crimping, it

should be confirmed that the insertion length of the stainless steel pipe is within 1-3mm of the depth line. Duringcrimping, the pressure should be increased slowly until the tool vibrates slightly when under pressure. The upper andlower jaws of the tool are completely closed to release the pressure and end the crimping process. Crimping of DN65-100 requires three crimpings to complete The specific installation steps are as follows:

① Slowly increase the pressure to 20Mpa and then release the pressure. ② After decompression, rotate the stainless steel pipe or ring die about 120°, then pressurize to 40Mpa andthendecompress;

③ Rotate the stainless steel pipe or ring die about 120° again, pressurize to 60Mpa, and the crimping is completed.

68When the connection is made by crimping, the pipes on both sides of the crimping part will have slight

deformation In order to ensure the sealing strength between the pipe and the fitting, a certain distance must bemaintained between the fittings.

After crimping, check the crimped pipe fittings to see if the ends of the pipe fittings have been crimpedinplaceto prevent poor construction. It is recommended to use a special hexagonal gauge to check the crimpingdimensions. When the gauge cannot be put into the crimping position, it should be crimped againat theoriginal crimping die position. If the specified requirements are still not met after multiple crimpings, checkwhether the crimping tools are intact and whether the jaws are worn Unqualified tools should not beusedreluctantly.

1. Cutting pipes

According to the required pipe size, the cutting of thin-walled stainless steel pipes should be done in a way that

does not significantly increase the temperature. The cutting tool should be a special electric pipe cutter for

marking and cutting. Do not use too much force when cutting to prevent the stainless steel pipe fromlosing its

roundness. Note that the cut should be kept perpendicular to the horizontal plane of the pipe, and the cut shouldnot be elliptical or have burrs, to ensure that the subsequent pipe is easy to deviate during the groove rolling. If

the construction site does not have the above special cutting tools, a grinding wheel saw can be used for cutting, but the following conditions must be met:

① Use a grinding wheel saw that does not contain iron;

② The grinding wheel saw should be used exclusively for cutting stainless steel pipes and should not be usedfor cutting other metal pipes. 2 Deburring (Figure 1)

After cutting, pay special attention to using special tools (chamfers, files, etc.) to completely remove the

internal and external burrs of the pipe end and wipe the dirt inside the pipe clean. Otherwise, when the

subsequent pipeline is installed and put into use, the burrs left in the pipe will block the discharge of dirt. The

accumulation of dirt will cause the chloride ions to exceed the standard and destroy the passivation filmon the

surface of the stainless steel product, thus causing corrosion and leakage 3. Groove preparation (Figure 2)

Put the steel pipe on the pipe support and measure it with a level meter to make the steel pipe in a horizontal

position and make the axis of the stainless steel pipe perpendicular to the positioning surface of the groove

machine. Then install the mold of the required corresponding specifications on the groove machine and debugthe mold to ensure that the upper roller is aligned with the center of the groove of the lower roller 4. Groove processing (Figure 3)

After starting the machine, lock the unloading valve, fix the stainless steel pipe with the fixed wheel, and

slowly press down the upper roller with the pressure rod The depth of each press should not be too deep The

time for one press is one circle of the stainless steel pipe. During the groove processing process, the stainless

steel pipe is strictly prohibited from displacement until the step surface of the upper roller is slightly in contact

with the protruding surface of the pipe or the required size is reached.

Groove maintenance

Keep the machine body clean, check the machine parts every three months, and keep the machine parts in goodcondition. Check the hydraulic oil frequently to see if it needs to be filled. Precautions for using the groove

During operation, it is strictly forbidden to put your fingers into the roller to avoid serious injury. During operation, the pipe and the machine must be balanced and no movement is allowed. Maintenance and inspection must be carried out when the power is completely cut off. The pipe size meets the requirements of relevant standards. The incision should be processed until it is flat and smooth, keep the surface clean, and no burrs should be left toavoid scratching the sealing rubber ring. When grooving, the pipe and the groove machine are in a horizontal state, and the center axis of the pipe is

perpendicular to the pressure port. When grooving, the pressure should be applied step by step and evenly to avoid uneven indentation depthaffecting the sealing effect. After the groove is completed, the groove depth needs to be measured to ensure that the groove depth meets thestandard before installation. When installing the clamp, tighten the nut evenly and alternately to prevent the rubber sealing ring fromwrinklinguntil the tightening is completed to ensure uniform and consistent sealing. During or after installation, the pipeline shall not be used for hanging, pulling or climbing. Stainless steel pipes and fittings shall not come into direct contact with cement mortar and concrete. To prevent

corrosion of the pipeline by halides, the pipeline shall be reasonably equipped with expansion compensationdevices and brackets.
