Features
★ Experience superior surface hardness and impressive tensile strength with our pipes, ensuring a high safety factor that stands the test of time.
★ Benefit from exceptional aging resistance, with a robust service life that exceeds 50 years, securing long-term reliability.
★ Discover unparalleled corrosion resistance against inorganic acids, alkalis, and salts, making it the ideal choice for industrial sewage discharge and transport.
★ Enjoy minimal maintenance with our pipelines designed for a smooth water flow, low friction, and reduced clogging.
★ Our materials boast a high oxygen index with self-extinguishing capabilities, enhancing safety standards.
★ With a linear expansion coefficient of merely 0.07mm/m.ºC, our pipelines maintain stability across temperatures. Offering low thermal conductivity and elastic modulus, they surpass cast iron in frost resistance.
★ Simplify your installation with easy bonding connections between pipes and fittings, enhancing construction efficiency and convenience.
★ Versatile for both industrial and civil building drainage, efficiently handling domestic sewage at temperatures up to 40ºC continuously and 80ºC instantaneously. Suitable for non-corrosive industrial wastewater.
Pipe connection
★ Ensure precision with our socket connection procedure, detailed as follows:
1. Begin by thoroughly cleaning the pipe and fitting sockets before bonding to ensure a secure fit.
2. Accurately measure the depth of the socket and mark the pipe port for precise alignment.
3. Apply adhesive evenly, starting with the socket, followed by the pipe; ensure a uniform coating.
4. Align correctly, insert fully to the marking, and rotate by 1/4 turn to secure the connection.
5. Carefully clear any excess adhesive from the socket to maintain a clean finish.
6. Allow the bonded pipe to stand until the interface has fully cured, ensuring durability.
★ Follow these provisions for the safe use of adhesives:
1. Use adhesives and cleaning agents judiciously, restricting access to trained operators only.
2. Ensure no open flames are present and maintain good ventilation at the bonding site.
3. Avoid construction below -10ºC, and never use fire to accelerate adhesive curing.
4. Equip personnel with protective gloves; if contact occurs with eyes, rinse immediately and seek medical attention.
Installation instructions
Saw pipe and groove:
Accurately determine pipe length based on measurements and fittings. Use fine-tooth saws or pipe cutting tools for precise cuts, ensuring flat and undeformed edges. Create a 15°-30° groove, not less than 3mm, with 1/3-1/2 wall thickness, removing debris post-grooving.
Socket protection:
After socket connection, clean any extruded adhesive with a lightly detergent-dipped cotton or dry cloth. Allow static curing based on adhesive performance and climate conditions, extending time for winter construction.
