Features
★ The surface hardness and tensile strength of our state-of-the-art Versatile PVC FITTINGS are simply unparalleled, ensuring a robust pipeline with a remarkable safety factor, perfect for all your needs.
★ Boasting an exceptional aging resistance, these pipe fittings are engineered to serve you reliably for over 50 years, offering peace of mind and enduring performance.
★ Built to withstand the harshest conditions, our pipeline exhibits outstanding corrosion resistance against inorganic acids, alkalis, and salts, making it an ideal choice for industrial sewage discharge and transport.
★ With a low friction coefficient, our pipeline ensures a smooth water flow, drastically reducing the chances of clogging and minimizing maintenance efforts, saving you time and hassle.
★ Featuring a high oxygen index, the material is self-extinguishing, offering enhanced safety and fire resistance for all applications.
★ The pipeline's minimal linear expansion coefficient of 0.07mm/m.ºC ensures that temperature-induced deformations are negligible. Coupled with its low thermal conductivity and elastic modulus, it surpasses cast iron drainage pipes in frost resistance.
★ Our pipe and fittings are designed for seamless bonding, allowing for a straightforward construction process, easy operation, and heightened installation efficiency.
★ Versatile in use, these fittings are perfect for both industrial and civil building drainage systems. They excel in safely managing indoor and outdoor sewage at continuous temperatures up to 40ºC and instantaneous instances up to 80ºC. Additionally, they handle industrial wastewater that is non-corrosive to the pipe.
Pipe Connection
★ For optimal results, adhere strictly to the following pipe socket connection procedures:
1. Meticulously clean both the pipe socket and the corresponding pipe fitting socket before applying bonding agents.
2. Accurately measure the socket depth and clearly mark the pipe port for precise alignment.
3. Apply adhesive starting with the socket, followed by the pipe; ensure an even and appropriate coat.
4. Align the pieces carefully, insert fully to the marking, and gently rotate 1/4 turn for a secure fit.
5. Thoroughly clean any excess adhesive from the socket to maintain a neat finish.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured, ensuring a strong bond.
★ For safe and effective use of adhesives, please observe the following guidelines:
1. Use adhesives and cleaning agents responsibly and restrict usage to trained personnel only.
2. Ensure no open flames are present at the bonding site and maintain good ventilation at all times.
3. Avoid construction in temperatures below -10ºC, and abstain from using fire to dry adhesive points.
4. Equip construction personnel with protective gloves. In case of contact with eyes, rinse immediately with ample water and seek medical attention.
Installation Instructions
Saw Pipe and Groove:
Determine the saw pipe length meticulously based on measured measurements and each connection’s dimensions. Utilize fine-tooth saws, cutters, or pipe cutting machines for accurate cuts. Ensure the cut is smooth with no section deformation. The socket area for bonding may be grooved to a 15°-30° angle with a medium board file, with a groove length not less than 3mm, and a thickness of 1/3-1/2 the pipe wall. Clean thoroughly after grooving.
Socket Protection:
Post-connection, clean extruded adhesive using cotton yarn or a dry cloth slightly moistened with acetone or similar detergents. Allow curing of the bond per adhesive performance and weather conditions, extending curing time during winter as needed.
