Features
★ Experience the superior surface hardness and remarkable tensile strength of these pipes, ensuring a high safety factor in all pipeline applications.
★ With outstanding aging resistance, these pipes promise a robust service life extending beyond 50 years, providing long-term reliability.
★ Exceptionally resistant to corrosion from inorganic acids, alkalis, and salts, our pipelines are ideal for industrial sewage discharge and transport.
★ Enjoy smooth water flow thanks to the low friction coefficient, minimizing blockages and reducing maintenance workload for hassle-free operation.
★ The material boasts a high oxygen index with self-extinguishing capabilities, enhancing safety in various environments.
★ With a linear expansion coefficient of merely 0.07mm/m.ºC, these pipes exhibit minimal deformation due to temperature changes, outperforming cast iron pipes in frost resistance.
★ Easy and efficient installation is achieved through the bonding of pipe and fittings, simplifying construction and boosting installation efficiency.
★ Perfect for both industrial and civil building drainage projects, these pipes handle continuous domestic sewage up to 40ºC and instant sewage discharges up to 80ºC. They are also suitable for industrial wastewater that is non-corrosive to the piping material.
Pipe connection
★ Ensure secure pipe socket connections by following these precise steps:
1. Begin by thoroughly cleaning both the pipe socket and fitting socket before applying adhesive.
2. Accurately measure socket depth and mark the pipe port accordingly.
3. Apply adhesive uniformly, first to the socket, then to the pipe, ensuring an even coating.
4. Align the components accurately, insert them to the marked depth in one motion, and twist 1/4 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 has fully cured.
★ Adhere to these guidelines for the safe use of adhesives:
1. Use adhesives and cleaning agents as needed, restricting use to trained personnel only.
2. Maintain a flame-free, well-ventilated environment at the bonding site.
3. Avoid construction in temperatures below -10ºC, and do not apply fire to adhesive points.
4. Equip workers with gloves. If adhesive contacts the eyes, rinse immediately with plenty of water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length based on layer-specific measurements and connected fittings. Use fine-tooth saws, cutters, and pipe cutting machines for precise cuts. Ensure clean, flat cuts without section deformation. File socket ends to a 15°-30° groove with a medium board file, ensuring a groove length of at least 3mm and a thickness of 1/3-1/2 of the pipe wall. Remove debris post-grooving.
Socket protection:
Clean extruded adhesive with cotton yarn or dry cloth moistened with a detergent like acetone after socket connection. Allow static curing in accordance with adhesive properties and climate. Extend curing time in winter conditions.
