Remarkable Features of Our Durable PVC FITTINGS
★ Unparalleled surface hardness and tensile strength ensure top-notch safety for every pipeline.
★ Outstanding aging resistance, with a robust lifespan extending beyond 50 years, offering longevity you can trust.
★ Exceptional resistance to corrosion from inorganic acids, alkalis, and salts makes it ideal for industrial sewage discharge and transportation.
★ With a low friction coefficient, our pipes guarantee smooth water flow, minimize blockages, and significantly reduce maintenance demands.
★ High oxygen index and self-extinguishing capabilities ensure superior safety standards.
★ Minimal linear expansion coefficient of 0.07mm/m.ºC offers negligible deformation under temperature variations, with superior thermal conductivity and elastic modulus, excelling in frost resistance compared to cast iron pipes.
★ Easy bonding of pipes and fittings allows for straightforward, efficient installation, boosting construction efficiency.
★ Perfect for both industrial and residential indoor & outdoor drainage systems, it supports continuous sewage up to 40ºC and instant discharges up to 80ºC. Compatible with non-corrosive industrial wastewater.
Pipe Connection Made Simple
★ Ensure seamless pipe socket connections by adhering strictly to these meticulous procedures:
1. Thoroughly clean the pipe socket and fitting socket prior to bonding.
2. Accurately measure socket depth and mark the pipe port for precision.
3. Apply the adhesive meticulously; begin with the socket, then the pipe fitting socket, ensuring even coverage.
4. Align direction carefully, insert fully to the marking, and rotate a quarter turn for secure fitting.
5. Clean excess adhesive from the socket for a clean finish.
6. Allow the bonded pipe to stand until the interface has fully cured for optimal security.
★ Adhering to adhesive safety measures is crucial for safe usage:
1. Only authorized personnel should handle adhesives and cleaning agents.
2. Maintain absence of open flames in bonding areas, ensuring excellent ventilation.
3. Avoid construction in temperatures below -10ºC and refrain from using fire to dry adhesive points.
4. Equip construction personnel with gloves; if adhesive contacts eyes, flush thoroughly with water and seek immediate medical attention.
Installation Instructions for Optimal Performance
Precision Sawing of Pipes and Grooves:
Determine the saw pipe length meticulously, layer by layer, based on measurements and fitting dimensions. Utilize fine tooth saws, cutters, or pipe cutting machines. Ensure cuts are flat, with no section deformation. File socket edges to a 15°-30° groove using a medium board file. Groove length should be at least 3mm, with depth being 1/3-1/2 of pipe wall thickness. Clean debris post-grooving for a perfect finish.
Safeguarding Socket Integrity:
After socket connection, cleanse the adhesive residue with cotton or cloth dampened with a detergent like acetone. Allow the interface to cure based on adhesive performance and climatic conditions. Extend curing during winter construction to ensure durability.
