★ Experience outstanding durability with our pipes—designed to resist aging and last over 50 years, guaranteeing long-term reliability.
★ With superior resistance to inorganic acids, alkalis, and salts, our pipelines are perfect for industrial sewage disposal and conveyance, offering peace of mind against corrosion.
★ Our pipes feature a low friction coefficient for seamless water flow, minimizing blockages and reducing maintenance efforts for hassle-free operation.
★ Benefit from materials with a high oxygen index and self-extinguishing properties, elevating safety and ensuring compliance with safety standards.
★ Enjoy minimal thermal deformation with a low linear expansion coefficient of just 0.07mm/m.ºC. Enhanced frost resistance outmatches traditional cast iron drainage options, making them perfect for diverse climates.
★ Our pipe and fitting connections are designed for simplicity and efficiency, allowing for easy bonding and quick installation without compromising on reliability.
★ Ideal for indoor and outdoor drainage projects in both industrial and civil buildings, our pipelines efficiently handle domestic sewage up to 40ºC continuously, peaking at 80ºC, and industrial wastewater that is non-corrosive.
Pipe Connection
★ Follow our precise socket connection procedure to ensure optimal performance and longevity.
1. Begin by meticulously cleaning both the pipe socket and fitting socket prior to bonding.
2. Accurately measure the socket depth and clearly mark the pipe port to ensure precise fitment.
3. Apply adhesive uniformly, coating the socket first, followed by the socket, for a perfect bond.
4. Carefully align and insert to the marked depth in one swift motion, turning it 1/4 turn to ensure a secure fit.
5. Promptly remove any excess adhesive from the socket to maintain a clean and professional finish.
6. Secure the bonded pipe upright until the adhesive has cured fully, ensuring maximum strength.
★ Adhere to these essential safety guidelines when using adhesives to ensure a safe working environment.
1. Use adhesives and cleaners responsibly, restricting access to trained operators only.
2. Maintain a flame-free zone around bonding areas and ensure proper ventilation to mitigate risks.
3. Avoid constructing below -10ºC and refrain from direct heat application to adhesive points to prevent damage.
4. Equip construction personnel with protective gloves; in case of eye contact with adhesive, rinse immediately and seek medical attention.
Installation Instructions
Saw Pipe and Groove:
Determine saw pipe lengths based on precise measurements, selecting fine tooth saws or cutting tools to ensure a clean, uniform cut. Prepare the socket area by filing a 15°-30° groove, ensuring it is between 1/3 and 1/2 of the pipe wall thickness for optimal adhesion. Post-grooving, clear away any debris to maintain cleanliness and effectiveness.
Socket Protection:
Post-connection, cleanse any extruded adhesive with a cotton cloth or dry wipe using a mild detergent such as acetone. Allow the interface to cure fully while considering adhesive properties and climate conditions, extending curing time as needed for winter construction.
