Features
★ Experience unmatched durability with our PVC FITTINGS, featuring a robust surface hardness and tensile strength that ensure a high safety factor for our pipelines.
★ Boasting excellent resistance to aging, our pipes promise a remarkable service lifespan of over 50 years, maintaining their integrity through time.
★ Engineered for resilience, our pipelines offer outstanding corrosion resistance against inorganic acids, alkalis, and salts, making them ideal for industrial sewage discharge and transportation.
★ With a low friction coefficient, these pipes guarantee smooth and uninterrupted water flow, minimizing the risk of clogging and reducing maintenance efforts significantly.
★ Our materials feature a high oxygen index and self-extinguishing capabilities, adding an extra layer of safety to your piping systems.
★ The linear expansion coefficient is impressively low at 0.07mm/m.ºC, resulting in minimal temperature-induced deformation. With low thermal conductivity and elastic modulus, our pipes excel in frost resistance compared to traditional cast iron drainage solutions.
★ Seamless installation is achieved with simple bonding methods, elevating operational convenience and maximizing installation efficiency with our compatible pipe fittings.
★ Perfectly suited for both industrial and civil indoor and outdoor drainage projects. Our pipes handle continuous domestic sewage up to 40ºC and instant sewage surges up to 80ºC, while also accommodating industrial wastewater that is non-corrosive.
Pipe Connection
★ For optimal results, adhere strictly to the following step-by-step procedures for pipe socket connections:
1. Ensure a clean surface by wiping the pipe and pipe fitting sockets thoroughly before applying adhesive.
2. Accurately measure the socket depth and clearly mark the pipe end.
3. Apply adhesive evenly: coat the socket first, then the pipe fitting socket, ensuring a uniform layer.
4. Carefully align and insert into the marked position in one motion, then rotate 1/4 turn to secure.
5. Remove any excess adhesive from the socket to ensure a clean finish.
6. Allow the bonded setup to stand until the interface is fully cured, securing a strong bond.
★ Follow these safety guidelines for the responsible use of adhesives:
1. Use adhesives and cleaning agents selectively, limiting access to trained operators only.
2. Maintain a flame-free zone at the bonding site and ensure adequate ventilation throughout the process.
3. Avoid construction in temperatures below -10ºC, and refrain from using fire to dry adhesive points.
4. Equip construction personnel with gloves; in case of adhesive contact with eyes, rinse thoroughly with water and seek medical attention immediately.
Installation Instructions
Saw Pipe and Groove:
Determine saw pipe lengths precisely based on measurements and dimensions of connected fittings. Use fine-tooth saws, cutters, or cutting machines for precision. Ensure cuts are flat without deformation. For the glued socket section, file a 15°-30° groove with a medium board file, ensuring a minimum groove length of 3mm and a depth corresponding to 1/3-1/2 of the pipe wall thickness. Clean off any debris post-grooving.
Socket Protection:
After socket connection, cleanse extruded adhesive with cotton or dry cloth dipped lightly in acetone or similar detergents. Allow static curing based on adhesive properties and weather conditions; extend curing time for winter projects.
