Features
★ With remarkable surface hardness and tensile strength, the pipe ensures a high safety factor, enhancing overall pipeline security.
★ Exhibiting superb aging resistance, this pipe promises a service life exceeding an impressive 50 years.
★ The pipeline boasts outstanding resistance to corrosion from inorganic acids, alkalis, and salts, making it ideal for industrial sewage discharge and transportation.
★ With a minimal friction coefficient, the pipeline ensures smooth water flow, significantly reducing the risk of blockages and lessening maintenance demands.
★ The material features a high oxygen index with excellent self-extinguishing properties for enhanced safety.
★ The pipeline's low linear expansion coefficient of 0.07mm/m.ºC minimizes deformation from temperature changes. It offers superior frost resistance compared to cast iron drainage pipes, along with low thermal conductivity and elastic modulus.
★ Pipe and pipe fittings can be easily bonded, simplifying construction methods. The operation is user-friendly, ensuring high installation efficiency.
★ Suitable for industrial and civil building drainage projects, both indoor and outdoor, where continuous domestic sewage temperature does not exceed 40ºC, and instant sewage discharge is up to 80ºC. Applicable for industrial wastewater that does not corrode the pipe.
Pipe connection
★ For a secure pipe socket connection, adhere strictly to the outlined procedures:
1. Ensure both the pipe socket and fitting socket are thoroughly clean before proceeding with bonding.
2. Accurately measure and mark the depth of the socket on the pipe port.
3. Apply the adhesive evenly, starting with the socket and then the pipe, ensuring a uniform coating.
4. Align correctly, insert into the marked section in one swift motion, and rotate 1/4 turn.
5. Clean any residual adhesive from the socket immediately.
6. Allow the bonded pipe to stand until the interface has fully cured.
★ Adhere to these safety guidelines when using adhesives:
1. Use adhesives and cleaning agents as needed; restrict access to non-operators.
2. Ensure no open flames are present at the bonding site; maintain good 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 the eyes, rinse with abundant water and seek medical attention promptly.
Installation instructions
Saw pipe and groove:
Measure each layer to determine the length of the saw pipe according to connected pipe fittings. Use fine tooth saws, cutters, or pipe cutting machines for clean cuts without deforming sections. File the socket area to a 15°-30° groove, ensuring a length of no less than 3mm and a thickness of 1/3-1/2 of the pipe wall. Ensure debris removal post-grooving.
Socket protection:
After socket connection, use cotton yarn or dry cloth, dipped in detergent like acetone, to clean extruded adhesive. Allow it to stand until the interface cures, considering adhesive performance and climatic conditions. Extend curing time appropriately in winter.
