Features
★ With outstanding surface hardness and superior tensile strength, these pipes boast an exceptional safety factor, ensuring reliability and durability in their application.
★ Engineered for longevity, this product exhibits excellent resistance to aging, delivering a remarkable service life that extends beyond 50 years.
★ The innovative pipeline demonstrates impressive corrosion resistance to inorganic acids, alkalis, and salts, making it an ideal choice for the discharge and transport of industrial sewage.
★ With a low friction coefficient, the pipeline guarantees a smooth water flow, minimizing the risk of blockages and significantly reducing maintenance efforts.
★ Crafted with a high oxygen index, the material features self-extinguishing capabilities, enhancing the safety of its use.
★ Designed with a minimal linear expansion coefficient of 0.07mm/m.ºC, the pipeline displays negligible temperature-induced deformation, with low thermal conductivity and elastic modulus, offering superior frost resistance compared to cast iron drainage pipes.
★ The pipe and fittings allow for a convenient bonding process, ensuring a simplistic construction method, facilitating easy operation, and enhancing installation efficiency.
★ Ideally suited for both industrial and civil indoor and outdoor drainage pipe projects, it effectively handles continuous domestic sewage discharge temperatures up to 40ºC and instantaneous discharges up to 80ºC. Industrial wastewater that is non-corrosive to the pipe is also compatible.
Pipe connection
★ For optimal results, the pipe socket connection should meticulously follow these procedures:
1. Clean both the pipe socket and pipe fitting socket thoroughly before proceeding with bonding.
2. Carefully measure the socket depth and accurately mark the pipe port.
3. Apply the adhesive evenly and judiciously, painting first on the socket and then on the pipe fitting socket.
4. Align properly and insert into the marked section in one decisive movement, twisting 1/4 turn to secure.
5. Remove any excess adhesive from the socket for a clean finish.
6. Allow the bonded pipe to stand undisturbed until the interface fully cures.
★ Adhere to these safety protocols for the secure use of adhesives:
1. Use adhesives and cleaning agents sparingly and only as needed. Unauthorized personnel should avoid use.
2. Ensure no open flames are present at the bonding site, and maintain excellent ventilation conditions.
3. Avoid construction in temperatures below -10ºC, and never use fire to dry adhesive points.
4. Construction workers must wear gloves. In case of accidental eye exposure to adhesive, rinse immediately with plenty of water and seek medical attention.
Installation instructions
Saw pipe and groove:
Each pipe's sawing length is precisely calibrated based on measured data and the dimensions of connected fittings. Use fine-tooth saws, cutters, or pipe-cutting machines for an impeccable cut. Ensure the cut edge is flat and free of deformation. A socket intended for adhesion should be beveled into a 15°-30° groove using a medium board file, with a minimum groove length of 3mm and depth of 1/3 to 1/2 of the pipe wall thickness. Thoroughly clear away all debris post-grooving.
Socket protection:
Post-connection, cleanse any extruded adhesive using a cotton yarn or dry cloth with a mild detergent like acetone. Let it remain static until fully cured, factoring in adhesive performance and weather conditions. Extend curing time appropriately during winter construction.
