★ Experience superior corrosion resistance against inorganic acids, alkalis, and salts, making these pipes ideally suited for industrial sewage discharge and transportation.
★ Designed with a low friction coefficient, our pipes facilitate smooth water flow, reducing blockages and minimizing maintenance efforts and costs.
★ Our material features a high oxygen index, offering excellent self-extinguishing properties for enhanced safety and fire resistance.
★ With a minimal linear expansion coefficient of 0.07mm/m.ºC, these pipes exhibit low temperature-induced deformation. Additionally, their small thermal conductivity and elastic modulus provide superior frost resistance compared to cast iron drainage pipes.
★ Enjoy seamless installation with our easy-to-bond pipe and fitting connections. The construction process is straightforward, ensuring convenience and high installation efficiency.
★ Perfect for both industrial and civil building drainage projects, these pipes can handle continuous domestic sewage discharge up to 40ºC and instant sewage discharge up to 80ºC. They are also suitable for industrial wastewater that does not corrode the pipes.
Pipe connection
★ For optimal results, follow these meticulous steps for pipe socket connection:
1. Ensure the pipe and fitting sockets are clean before commencing bonding.
2. Accurately measure the socket depth and mark the pipe end for precision.
3. Apply adhesive evenly, starting with the socket and then the pipe end for a consistent bond.
4. Align the components carefully, insert firmly to the marked point, and rotate 1/4 turn for perfect fit.
5. Remove any excess adhesive from the socket for a neat finish.
6. Allow the pipe to stand until the bond is fully cured, ensuring a robust connection.
★ Adhere to these safety guidelines for using adhesives:
1. Use adhesives and cleaning agents responsibly, restricting use to trained operators.
2. Maintain good ventilation and avoid open flames at bonding sites for safety.
3. Refrain from construction in temperatures below -10ºC and never heat the adhesive point with open flames.
4. Equip construction personnel with gloves for protection; if adhesive contacts eyes, rinse with ample water and seek immediate medical attention.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length precisely based on measurements and connected fitting dimensions. Utilize fine-tooth saws, cutters, or pipe cutting machines for accurate cuts. Ensure fractures are flat with no deformation. File socket areas into a 15°-30° groove, typically not less than 3mm in length, and 1/3 to 1/2 of the wall thickness. Clean debris for a pristine finish.
Socket protection:
Clean extruded adhesive around the socket using cotton yarn or dry cloth with a mild detergent like acetone. Allow static curing based on adhesive performance and climate. Extend curing time during winter construction for optimal results.
