PVC-U drainage pipe and pipe fittings are made of polyvinyl chloride (PVC) resin as the main raw material, adding appropriate amount of additives, extruded and injection molded pipe and pipe fittings, which can be used for indoor and outdoor drainage of high-rise and multi-storey industrial and civil buildings. system. The continuous discharge of domestic sewage temperature is not more than 40 ° C, and the instantaneous discharge temperature is not more than 80 ° C.
Product classification: According to different connection forms, it can be divided into adhesive edge type and elastic sealing ring connection type. Antong brand PVC-U drainage pipe is adhesive connection type pipe. Executive standard: GB/T5836.1-2006 "hard polyvinyl chloride (PVC-U) pipe for building drainage" GB/T5836.2-2006 "hard polyvinyl chloride (PVC-U) pipe fittings for building drainage" Specification: pipe Classified by outer diameter, the specifications are 32, 40, 50, 75, 90, 110, 160, 200 eight specifications.

Scope of application: It can be used in indoor and outdoor drainage systems for high-rise and multi-storey industrial and civil buildings. The continuous discharge of domestic sewage temperature is not more than 40 ° C, and the instantaneous discharge temperature is not more than 80 ° C. Usage and precautions: 1. Shearing: According to the length of use, use a hacksaw to gently saw at the shearing position. The end surface of the pipe should be flat and perpendicular to the axis. Cut a pipe end at 30-45 degrees to the outside corner. The thickness of the pipe end is 1/4-1/3. 2. Gluing: The inner wall of the pipe socket and the outer wall of the pipe end are inserted, wiped clean with a dry cloth, and the insertion depth mark is drawn. 3. Adhesive brushing should be applied to the inside of the socket of the pipe fitting and the outside of the socket. The adhesive should be quickly, evenly and properly. After painting, find the positive direction, insert the pipe into the socket, and apply pressure to insert the pipe end into the depth mark. And rotate 90 degrees, the pipe socket must not be hit with a hammer. 4. One set of expansion joints for each layer of the riser is used to compensate for the thermal expansion and contraction of the plastic pipe. 5. If each layer of the riser is less than 3 meters in height, consider setting one of the pipe sets, and the horizontal pipe shall be installed with a lifting card of 0.8m per specified length.
