Features
★ Experience unmatched durability with our pipes featuring excellent surface hardness and tensile strength, ensuring maximum safety and reliability for your pipeline.
★ Benefit from remarkable aging resistance; enjoy a service life that exceeds 50 years, providing enduring performance and value.
★ Our pipeline offers superior resistance to inorganic acids, alkalis, and salts, making it the ideal choice for industrial sewage discharge and transportation.
★ Enjoy smooth water flow with minimal friction, reducing the risk of clogs and lowering maintenance efforts significantly.
★ The material boasts a high oxygen index with self-extinguishing capabilities, adding a layer of safety to your operations.
★ With a minimal linear expansion coefficient of just 0.07mm/m.ºC, our pipes exhibit minimal deformation from temperature changes, superior thermal insulation, and enhanced frost resistance compared to traditional cast iron pipes.
★ Simplify your installation process with our easy bonding method for pipes and fittings, ensuring high installation efficiency and convenience.
★ Perfect for both industrial and residential projects, our drainage pipeline supports continuous domestic sewage discharge temperatures up to 40ºC and instant sewage discharge up to 80ºC, accommodating non-corrosive industrial wastewater as well.
Pipe Connection
★ Follow these meticulous steps for a successful pipe socket connection:
1. Thoroughly clean the pipe socket and fitting socket before bonding to ensure optimal adhesion.
2. Precisely measure and mark the socket depth to prepare for accurate joining.
3. Apply adhesive uniformly; start with the socket followed by the pipe fitting socket, ensuring even coverage for a robust connection.
4. Carefully align and insert into the marked point in one motion, turning it 1/4 turn to lock in place.
5. Remove any excess adhesive from the socket to maintain a clean and tidy finish.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured, securing a durable bond.
★ Adhere to these safety guidelines when using adhesives:
1. Only authorized personnel should handle adhesives and cleaning agents, minimizing risks to non-operators.
2. Maintain a flame-free environment with excellent ventilation at the bonding site for optimal safety.
3. Avoid construction in temperatures below -10ºC; refrain from using fire to accelerate the adhesive process.
4. Equip construction personnel with gloves; in case of eye contact, rinse immediately with ample water and seek medical attention.
Installation Instructions
Saw Pipe and Groove:
Carefully determine the saw pipe length based on precise measurements and the dimensions of connected fittings. Use fine-tooth saws, cutters, and pipe cutting machines for a clean cut. Ensure the fracture is even and free from deformation. File the socket area into a 15°-30° groove using a medium board file, with a groove length of no less than 3mm and thickness between 1/3-1/2 of the pipe wall. Clear debris post-grooving for a pristine finish.
Socket Protection:
Post-connection, gently clean any extruded adhesive with cotton or a dry cloth moistened with detergent, like acetone. Allow to cure according to adhesive properties and weather conditions, extending curing time during winter to ensure maximum bond strength.
