PVC drainage pipe installation process

PVC drainage pipe before installation, we must ensure that the pipe fracture to be flush, with a circular file or scraper to remove the thorn inside and outside the fracture, the socket should be inserted before the test to be inserted, not all inserted, usually for the socket 3/4 Depth, and mark. After passing the test, with cotton silk socket socket around the water, dust wipe clean. Apply the adhesive with a brush, apply the socket first and then the socket after it should be axially brushed. The action should be swiftly applied and the amount of the adhesive applied should be appropriate and no leakage or drip should be allowed. After the coating is completed, then find the direction of the tube gently inserted into the socket, the straight after the squeeze, the tube should be inserted deeper than the mark, and to ensure the interface perpendicularity, and then allowed to stand 2 to 3 minutes. Interface process, can be slightly rotated to facilitate the adhesive evenly distributed, but not more than 1/4 circle, not inserted in the end after the rotation.

Sticky immediately after the end of the cotton with a spill will clean the adhesive, buried pipe can not be wiped. Winter construction, the ambient temperature shall not be lower than -100C, when the ambient temperature is lower than -100C, should take cold frost measures, the construction site should keep the air unobstructed, not closed. PVC drainage pipe used in the process, we must pay attention to the riser and cross-pipe connection should be installed oblique three-pass or oblique four-way, out of the cross-tube and riser at the use of two 45 ° elbow connection or a 45 ° The elbow is connected to a 45 ° tee, which reduces the chances of blockages in the pipeline, reduces the formation of water tongues at the connections, and reduces the pressure fluctuations in the drainage system.

PVC drainage pipe is a sanitary grade PVC resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, toner and other plastic extruder extrusion molding and injection molding machine, through the cooling, Curing, stereotypes, testing, packaging and other processes to complete the pipe, tube production.

The general specifications of PVC drainage pipes are 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 200mm, 250mm, 315mm respectively. The length is usually 4m or 6m, if the customer requests, it can negotiate .

PVC pipe drainage pipe surface hardness and tensile strength, pipe safety factor. And PVC drain has a very good anti-aging properties, the normal life of up to 50 years. PVC pipe drainage on the inorganic acid, alkali, salt, excellent corrosion resistance, suitable for industrial wastewater discharge and transport. PVC drainage pipe friction coefficient is small, smooth flow, easy to block, less maintenance workload. PVC drainage pipe oxygen index, with self-extinguishing. PVC pipe drainage pipeline coefficient of linear expansion, 0.07mm / ℃, small deformation by temperature. Thermal conductivity and elastic modulus of small, compared with cast iron drainage pipe antifreeze performance.

PVC drainage pipes, pipe fittings can be used to connect the bond, the construction method is simple, easy to operate, installation work efficiency. After the socket connector is connected, the adhesive should be squeezed out of cotton or dry cloth with a little acetone and other cleaning agents scrub clean. According to the adhesive properties and climatic conditions until the interface curing. Curing time in winter should be extended.
