Features
★ Experience the superior surface hardness and robust tensile strength of our pipe, ensuring a remarkable pipeline safety factor.
★ Benefit from outstanding aging resistance, with a normal service lifespan extending beyond an impressive 50 years.
★ Enjoy exceptional corrosion resistance against inorganic acids, alkalis, and salts, making it ideal for industrial sewage discharge and transport.
★ Appreciate the pipeline's low friction coefficient, which guarantees smooth water flow, minimizes blockages, and reduces maintenance demands.
★ The material boasts a high oxygen index and features superior self-extinguishing properties, enhancing safety.
★ With a small linear expansion coefficient of just 0.07mm/m.ºC, the pipe's minimal thermal deformation, low thermal conductivity, and elastic modulus provide superior frost resistance compared to cast iron drainage pipes.
★ Benefit from easy installation with pipe and fittings connections that can be bonded, simplifying construction, improving convenience, and boosting installation efficiency.
★ Ideal for industrial and civil building drainage projects, whether indoors or outdoors. Perfect for continuously discharging domestic sewage at temperatures up to 40ºC, or instant sewage discharges up to 80ºC. Suitable for industrial wastewater that doesn't corrode the pipe.
Pipe connection
★ Ensure optimal pipe socket connections by following these precise procedures:
1. Thoroughly wipe the pipe socket and fitting socket clean prior to bonding for a seamless connection.
2. Accurately measure the socket depth and mark the pipe port to guide the bonding process.
3. Apply adhesive meticulously, starting with the socket and then the socket, ensuring uniform and appropriate coverage.
4. Align properly, insert the pipe into the marked section in one swift motion, and rotate 1/4 turn for secure bonding.
5. Carefully wipe away any excess adhesive remaining in the socket for a clean finish.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured.
★ Adhere to these safety provisions for the safe use of adhesives:
1. Use adhesives and cleaners as needed; restrict use to trained personnel only.
2. Maintain a flame-free environment at the bonding site, ensuring excellent ventilation.
3. Avoid construction in temperatures below -10ºC and refrain from using fire to heat adhesive points.
4. Equip construction staff with gloves. In case of eye contact with adhesive, rinse immediately with copious water and seek medical attention.
Installation instructions
Saw pipe and groove:
Cut pipe lengths precisely based on measured dimensions and the fittings connected. Select fine-tooth saws, cutters, or pipe-cutting machines for clean cuts. Ensure fractures are flat with no sectional deformation. File socket parts into a 15°-30° groove with a medium board file; grooves should be at least 3mm long and 1/3 to 1/2 the thickness of the pipe wall. Remove debris post-grooving for optimal bonding.
Socket protection:
After connecting, clean extruded adhesive with cotton yarn or dry cloth using a mild detergent like acetone. Keep static until fully cured based on adhesive performance and climate conditions. In winter, allow extra time for curing.
