★ Experience unmatched longevity with our products, offering exceptional aging resistance and a reliable service life exceeding half a century.
★ Engineered for excellence, our pipeline demonstrates superior corrosion resistance against inorganic acids, alkalis, and salts, making it ideal for industrial sewage discharge and transportation.
★ With a low friction coefficient, our pipeline ensures a seamless flow of water, minimizing the risk of blockages and reducing maintenance efforts significantly.
★ Benefit from high oxygen index materials with excellent self-extinguishing properties, providing enhanced safety and reliability.
★ Boasting a minimal linear expansion coefficient of 0.07mm/m.ºC, our pipeline is engineered for minimal deformation due to temperature changes. Its low thermal conductivity and elastic modulus offer superior frost resistance compared to traditional cast iron pipes.
★ Simplify your installation process with our easy-to-bond pipe and fittings connection, designed for straightforward construction and high operational efficiency.
★ Perfectly suited for both industrial and residential building projects, our pipelines are ideal for indoor and outdoor drainage systems. Handles continuous domestic sewage discharge under 40ºC and instant sewage temperatures up to 80ºC. Safe for industrial wastewater that doesn't corrode pipes.
Pipe connection
★ Ensure a flawless pipe socket connection by meticulously following these detailed steps:
1. Begin by thoroughly cleaning both the pipe socket and pipe fitting socket before applying adhesive.
2. Accurately measure the socket depth, marking the pipe port for precise alignment.
3. Apply adhesive with care, beginning with the socket and ensuring an even, suitable coating.
4. Carefully align and insert into the marked section, rotating a quarter turn for optimal fit.
5. Clean any excess adhesive from the socket meticulously.
6. Allow the bonded pipe to stand until the interface is fully cured, ensuring optimal bonding.
★ For safe adhesive use, adhere strictly to the following guidelines:
1. Use adhesives and cleaning agents judiciously; restrict access to trained operators only.
2. Maintain a flame-free environment at bonding sites with adequate ventilation.
3. Avoid construction under -10ºC, and do not apply heat to the adhesive point.
4. Equip construction personnel with gloves. In case of accidental eye contact with adhesive, rinse immediately with abundant water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine saw pipe length meticulously based on precise measurements and the dimensions of each connected fitting. Opt for fine tooth saws, cutters, or pipe cutting machines for best results. Ensure a clean, smooth cut with no sectional deformations. File the socket area into a 15°-30° groove, achieving a minimum groove length of 3mm, with thickness between 1/3 and 1/2 of the pipe wall. Clear away any debris post-grooving.
Socket protection:
Post-connection, cleanse the extruded adhesive using cotton yarn or dry cloth with a mild detergent like acetone. Allow to set statically until fully cured, adjusting for adhesive properties and weather conditions. Extend curing time for winter constructions as necessary.
