Features
★ The Versatile Flexible Reinforced PVC PIPE boasts exceptional surface hardness and tensile strength, ensuring an unparalleled level of safety and reliability in all your pipeline applications.
★ With an outstanding resistance to aging, this pipe is engineered for longevity, boasting a service life that can span over 50 years, standing the test of time with ease.
★ Unrivaled in its resistance to corrosion, this masterpiece of engineering is perfect for handling industrial sewage. Its ability to withstand inorganic acids, alkalis, and salts makes it an ideal choice for industrial wastewater management.
★ Designed for efficiency, the pipe features a remarkably low friction coefficient, allowing water to flow effortlessly. Its clog-resistant nature reduces maintenance demands significantly.
★ Featuring a high oxygen index and superior self-extinguishing properties, the material ensures enhanced safety in every application.
★ The pipe's minimal linear expansion coefficient of just 0.07mm/m.ºC guarantees minimal deformation with temperature variations. Its low thermal conductivity and elastic modulus, paired with superior frost resistance, outperform traditional cast iron drainage systems.
★ Seamless and efficient installation is made possible by the pipe's ability to be easily bonded with fittings, offering a simple, convenient, and highly efficient construction method.
★ Ideal for a wide range of applications, this pipe excels in both industrial and civil building drainage projects. It handles continuous discharges of domestic sewage at temperatures up to 40ºC and can manage instant discharges at temperatures up to 80ºC. It is also suitable for industrial wastewater that does not pose a threat of corrosion.
Pipe connection
★ For optimal performance, adhere strictly to the following procedures when connecting pipe sockets:
1. Ensure the pipe socket and fitting socket are meticulously cleaned to guarantee a strong bond.
2. Accurately measure and clearly mark the depth of the socket on the pipe port for precision fitting.
3. Apply adhesive evenly and appropriately, starting with the socket followed by the pipe, ensuring comprehensive coverage.
4. Align correctly and insert the pipe into the marked position in one swift motion, followed by a 1/4 turn for secure attachment.
5. Clean any excess adhesive from the socket to maintain a neat finish.
6. Allow the bonded pipe to stand undisturbed until the interface has fully cured, securing its integrity.
★ Adhere to these crucial guidelines for the safe use of adhesives:
1. Use adhesives and cleaning agents judiciously, keeping them out of the hands of non-operational personnel for safety.
2. Maintain a flame-free environment during bonding procedures, ensuring excellent ventilation throughout.
3. Avoid construction in temperatures below -10ºC and refrain from using fire to cure adhesive points.
4. Equip construction personnel with gloves for protection. In the event of adhesive contact with eyes, rinse immediately with ample water and seek medical attention promptly.
Installation instructions
Saw pipe and groove:
Determine the length of the saw pipe through meticulous layer-by-layer measurements, factoring in the dimensions of each connecting fitting. Utilize fine tooth saws, cutters, or pipe cutting machines for precision. Ensure the cut is smooth with no deformation at the section. For socket adhesion, craft a 15°-30° groove using a medium board file, with a groove length no less than 3mm and a groove thickness between 1/3 and 1/2 of the pipe wall thickness. Clear debris post-grooving to prepare for flawless adhesion.
Socket protection:
Following socket connection, cleanse any excess adhesive with a cotton yarn or dry cloth lightly soaked in a solvent like acetone. Allow the interface to set undisturbed until fully cured, taking into account adhesive properties and climate conditions. Extend curing time appropriately during winter conditions for robust results.
