Features
★ Our pipes boast an exceptional surface hardness and tensile strength, ensuring a high safety factor for your pipeline infrastructure.
★ With excellent aging resistance, our pipes can serve reliably for over 50 years.
★ Created to resist inorganic acids, alkalis, and salts, these pipes are ideal for industrial sewage discharge and transportation.
★ The low friction coefficient of our pipes ensures smooth water flow, reducing the likelihood of clogs and minimizing maintenance.
★ Featuring a high oxygen index and self-extinguishing properties, our material ensures enhanced safety.
★ Our pipes feature a minimal linear expansion coefficient of 0.07mm/m.ºC, offering excellent thermal stability. Their small thermal conductivity and elastic modulus provide superior frost resistance compared to cast iron drainage pipes.
★ Easy bonding of pipes and fittings ensures simple construction, convenient operation, and high installation efficiency.
★ Perfect for industrial and residential drainage projects, our pipes handle continuous domestic sewage up to 40ºC and instant discharges up to 80ºC. Suitable for non-corrosive industrial wastewater.
Pipe connection
★ Follow these meticulous steps for pipe socket connections:
1. Clean the pipe socket and fitting socket thoroughly before bonding.
2. Measure and mark the depth of the socket on the pipe port.
3. Apply the adhesive evenly: coat the socket first, followed by the pipe socket.
4. Insert and align in one go, turning 1/4 of a turn for a secure fit.
5. Wipe off any excess adhesive from the socket.
6. Allow the bonded pipe to stand until the interface is fully cured.
★ Ensure safe use of adhesives with these guidelines:
1. Only use adhesives and cleaning agents as needed; non-operators should avoid handling them.
2. Maintain good ventilation and avoid open flames at bonding sites.
3. Do not construct below -10ºC, and avoid heating adhesive points with fire.
4. Wear gloves during construction. If adhesive contacts eyes, flush with plenty of water and seek immediate medical care.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length based on measured dimensions of connected fittings. Use fine tooth saws, cutters, or pipe cutting machines for cutting. Ensure a smooth cut with no deformation. File the socket part to a 15°-30° groove (length ≥ 3mm, thickness 1/3-1/2 of wall thickness). Remove debris after grooving.
Socket protection:
After socket connection, clean extruded adhesive with cotton yarn or dry cloth dipped in detergent (e.g., acetone). Allow the interface to cure according to adhesive performance and climate conditions. Extend curing time during winter construction.
