★ Enjoy unrivaled aging resistance, guaranteeing a service life that exceeds an impressive 50 years, making it a long-lasting choice.
★ Our pipelines boast outstanding resistance to corrosion from inorganic acids, alkalis, and salts, perfectly suited for industrial sewage discharge and transport.
★ With a low friction coefficient, our pipelines offer smooth water flow, reducing blockages and minimizing maintenance efforts.
★ Crafted from materials with a high oxygen index, our pipes possess excellent self-extinguishing properties, enhancing safety in use.
★ Featuring a minimal linear expansion coefficient of 0.07mm/m.ºC, our pipes demonstrate reduced deformation from temperature changes, superior thermal conductivity, and elasticity, offering better frost resistance than cast iron drainage pipes.
★ Experience the simplicity and convenience of high-efficiency installation with our easily bonded pipe and fitting connections.
★ Ideally designed for industrial and civil building drainage projects, capable of handling continuous domestic sewage temperatures up to 40ºC and instant sewage temperatures up to 80ºC. Suitable for industrial wastewater that does not corrode the pipes.
Pipe connection
★ Follow these essential procedures for precise pipe socket connections:
1. Ensure the pipe socket and fitting socket are meticulously cleaned before bonding to achieve the best results.
2. Accurately measure the socket depth and mark the pipe port for precise alignment.
3. Apply the adhesive meticulously, starting with the socket, then the pipe, ensuring an even and adequate coating.
4. Align, insert into the marked area in one motion, and rotate 1/4 turn to secure the bond.
5. Carefully wipe away any excess adhesive from the socket for a clean finish.
6. Allow the bonded pipe to stand until the interface is fully cured, ensuring maximum strength.
★ Adhere to these guidelines for the safe use of adhesives:
1. Use adhesives and cleaning agents judiciously, restricting access to trained personnel only.
2. Maintain a flame-free and well-ventilated environment at the bonding site for safety.
3. Avoid construction in temperatures below -10ºC and refrain from using fire to dry adhesive points.
4. Equip construction personnel with gloves. For any adhesive contact with eyes, rinse immediately with water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine the length for saw pipe layer by layer based on precise measurements and dimensions of each connected fitting. Select fine tooth saws, cutters, and pipe cutting machines. Ensure cuts are flat without sectional deformation. File socket areas to a 15°-30° groove using a medium board file, with groove lengths not less than 3mm and thicknesses 1/3-1/2 of the pipe wall. Clear debris post-grooving.
Socket protection:
After securing the socket connection, use cotton yarn or dry cloth with a touch of detergent like acetone to clean the extruded adhesive. Allow the connection to cure according to adhesive performance and current weather conditions. Extend curing time appropriately during winter construction.
