Pvc-U drainage pipe connection

1.Saw pipe and bevel

A.Tools for sawing pipes should be fine-toothed saws, cutters, pipe cutters and other tools. The cuts should be flat and perpendicular to the pipe body, and there should be no deformation in the cross section.

B.The socket can be filed with a medium-sized plate file to form a 15°-30° bevel. The thickness of the bevel is 1/3-1/2 of the thickness of the pipe wall. The length is generally not less than 3mm. After the bevel is completed, the debris should be removed clean.

2.Pipe end socket depth

The length of the saw pipe is determined layer by layer based on actual measurements and combined with the size of each connecting pipe fitting. Pipe sawing tools should use fine-tooth saws, cutters, pipe cutters and other tools. The fracture should be flat and there should be no deformation at the cross section. The socket part to be bonded can be filed into a 15o~30o bevel with a medium plate file. The length of the groove is generally not less than 3mm, and the thickness of the groove should be 1/3~1/2 of the pipe wall thickness. After the bevel is completed, the debris should be removed.

3.Apply adhesive

It is recommended to use our company's special adhesive for PVC. Use the small brush delivered with the adhesive to dip it in the adhesive and apply it on the joint surface of the pipe and fittings. The application should be done axially and quickly and evenly. The adhesive should be applied in an appropriate amount without leakage. Apply or apply too thickly. Special attention must be paid during winter construction. The socket should be painted first and then the socket.

4.Connection of socket interface

After applying adhesive to the socket, you should immediately insert the pipe into the socket in the correct direction, so that the insertion depth of the pipe end meets the drawn mark, and ensure the straightness of the socket interface and the correct position of the interface. This should be maintained for 2-3 minutes to prevent If the interface slips, the error between the prefabricated pipe end nodes should not be greater than 5mm.

5.Maintenance of socket interface

After the socket interface is connected, the extruded adhesive should be wiped clean with cotton gauze or a dry cloth dipped in detergent. Allow the joint to solidify based on the properties of the adhesive and climatic conditions. During construction in winter or rainy season, the curing time should be appropriately extended.
