Features
★ Experience exceptional surface hardness and tensile strength with our Durable CPVC Plastic Pipe Fitting, ensuring a high pipeline safety factor for peace of mind.
★ Boasting remarkable aging resistance, our product offers a normal service life of over 50 years, providing long-lasting reliability.
★ The pipeline's outstanding corrosion resistance against inorganic acids, alkalis, and salts makes it perfect for industrial sewage discharge and transport needs.
★ With a low friction coefficient, our pipeline guarantees smooth water flow, reducing the risk of clogs and minimizing maintenance workload.
★ Made from material with a high oxygen index, our pipe fitting is self-extinguishing for enhanced safety.
★ Featuring a small linear expansion coefficient of just 0.07mm/m.ºC, our pipe fitting minimizes temperature-induced deformation, providing superior frost resistance compared to cast iron drainage pipes.
★ Easily connect pipes and fittings with our simple, convenient bonding method, optimizing installation efficiency with a high success rate.
★ Ideal for industrial and civil building drainage projects, our pipeline manages continuous domestic sewage discharge below 40ºC and instant sewage discharge up to 80ºC, while withstanding industrial wastewater that does not corrode the pipe.
Pipe connection
★ For pipe socket connections, adhere strictly to these procedures to ensure secure and reliable fittings:
1. Clean the pipe and fitting sockets thoroughly before bonding to ensure a strong, seamless connection.
2. Accurately measure socket depth and mark the pipe port for precision during installation.
3. Apply adhesive methodically, starting with the socket followed by the pipe, for an even and appropriate coating.
4. Carefully align, insert into the marked part in one motion, and rotate a quarter turn for secure bonding.
5. Remove any excess adhesive from the socket for a clean finish.
6. Allow the bonded pipe to stand until the interface is fully cured, ensuring optimal connection strength.
★ Ensure safe adhesive use by following these vital guidelines:
1. Use adhesives and cleaning agents responsibly, restricting access to trained operators only.
2. Bonding points must remain free of open flames, with ample ventilation to ensure safety.
3. Avoid construction below -10ºC, and refrain from using fire to heat adhesive points.
4. Construction personnel should wear gloves for protection; in case of adhesive contact with eyes, rinse thoroughly with water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length by measuring each layer in conjunction with the dimensions of connected fittings. Utilize fine-tooth saws, cutters, or pipe cutting machines for smooth cuts. Ensure fracture surfaces are flat without deformations. For optimal bonding, file the socket part to a 15°-30° groove with a medium board file. The groove should not be less than 3mm, with thickness between 1/3 to 1/2 of the pipe wall. Post-grooving, remove all debris.
Socket protection:
After socket connection, wipe off any extruded adhesive using cotton yarn or a dry cloth with a mild detergent like acetone. Allow the interface to cure in static conditions, adjusting curing time during winter for optimal bond strength.
