Identification of VASEN PVC-U fittings

Thereare two strengthening ribsat the end of the fitting
There are six flat rectangle ribs along the socket port which is divided into six equal parts.
Attheback of the fiting,there isa thinand longstrengtheningrib (except cross and socket fittings)
The trade ismarked on the fitting
PVC-Ufitings are now awarded 14 appearance patents and 4 utility model patents

Funcition of the Strengthening Ribs

Strengthen:

Theraised ribsaround the wall outside can helpto strenghenand make the fitting thickerand stronger.What'smore,itcan helptoresisit breakageand impact.

Protection:

Theframeworks formed by the raised ribs can quickly response to the change of acting force when theyare loading.

Normative installation:

The strengthen ribs can be the marking line that can ensure correctness of the installation, speed up the process of the installationand raise the efficiency.

Humanizeddesign:

The design of the strengthen ribs at the end of the fiting gives the operators good hand feel andmakes ituneasyto slip.The installationof theupper layer particularly reflects this advantage.When the glue isapplied and the pipe is installed,the force point can be easily rotated or gripped.Glue pastes evenly or change the direction of the pipe.

Connection Technology

Pipe instalation shall be caried out inaccordance with the technical requirements of the drainage pipe

The glue connection stepsare following as below:

Step 1:

Wipe pipesand fitings,then mark the insertion depth according to the fiting depth; Step2:

Theadesiveshouldbeappliedtotheinsidesocketofthepipequicklyevenlyandappropriately,thenappliedtothe outside socket of the pipe within the range of the mark;

Step 3:

Findthedirectionandinsertthetubeintothesocket.Putpressuretoinsert thepipeendintothepre-markeddepthand rotatethe pipe by90degrees.Donothitwitha hammerduringinsertion.After thesocket interfaceisbonded,the extruded glue should be wiped clean.Then wait until the connection is solidified.
