Features
★ Our pipes boast exceptional surface hardness and remarkable tensile strength, ensuring an unparalleled safety factor. With these robust characteristics, you can trust in the durability and reliability of our piping solutions.
★ Experience outstanding longevity with our products, as they demonstrate remarkable resistance to aging, offering you a dependable service life that can extend beyond 50 years.
★ Our pipelines excel in resisting corrosion from inorganic acids, alkalis, and salts, making them an ideal choice for the discharge and transport of industrial sewage.
★ With a low friction coefficient, our pipelines ensure smooth water flow, significantly reducing the risk of clogs and minimizing maintenance efforts.
★ Our materials are engineered with a high oxygen index and exhibit self-extinguishing properties, enhancing safety and reliability.
★ Featuring a minimal linear expansion coefficient of just 0.07mm/m.ºC, our pipelines exhibit minimal deformation due to temperature changes. Additionally, with low thermal conductivity and elastic modulus, they offer superior frost resistance compared to traditional cast iron drainage pipes.
★ Achieve effortless installation with our pipe and fitting connections, thanks to a simple and efficient bonding method that enhances construction convenience and boosts installation efficiency.
★ Ideal for both industrial and civil building drainage projects, our pipelines support the continuous discharge of domestic sewage at temperatures up to 40ºC and can accommodate instant sewage discharges up to 80ºC. Additionally, they are suited for industrial wastewater that does not corrode the pipes.
Pipe connection
★ Ensure the integrity of your pipe connections by meticulously following these essential procedures:
1. Begin by thoroughly cleaning both the pipe socket and fitting socket before the bonding process to ensure optimal adhesion.
2. Accurately measure the socket's depth and mark the pipe port for precise insertion and alignment.
3. Carefully apply the adhesive, starting with the socket and then the pipe socket, ensuring a uniform and adequate coating for reliable bonding.
4. Align the components accurately, insert precisely to the marked depth, and rotate the fitting by 1/4 turn to ensure a secure connection.
5. Gently remove any excess adhesive from the socket to maintain a clean and professional finish.
6. Allow the bonded pipe to stand until the interface has fully cured, ensuring a strong and durable connection.
★ Follow these crucial safety guidelines when using adhesives to ensure safe and effective application:
1. Utilize adhesives and cleaning agents only as required, restricting usage to authorized personnel for enhanced safety.
2. Maintain a flame-free environment at the bonding site and ensure adequate ventilation to prevent hazardous conditions.
3. Avoid conducting operations at temperatures below -10ºC, and refrain from using open flames to accelerate adhesive curing.
4. Equip construction personnel with protective gloves, and in case of accidental contact with eyes, rinse immediately with copious amounts of water and seek medical attention promptly.
Installation instructions
Saw pipe and groove:
Determine the length of the saw pipe based on precise measurements and the dimensions of each connecting pipe fitting. Choose fine-tooth saws, cutters, or pipe cutting machines for a clean cut, ensuring no sectional deformation. File the socket area to be glued into a 15°-30° groove using a medium board file. Ensure the groove is at least 3mm long and 1/3-1/2 the wall thickness. Once completed, remove all debris meticulously.
Socket protection:
Following socket connection, carefully clean the extruded adhesive using cotton yarn or a dry cloth moistened with a gentle detergent like acetone. Allow the interface to cure according to adhesive performance and ambient conditions, extending curing time for winter construction as necessary.
