Features
★ The pipe boasts exceptional surface hardness and tensile strength, ensuring a high safety factor for any pipeline application.
★ With superb resistance to aging, this pipe promises a remarkable service life of over 50 years, making it a long-term investment.
★ Engineered for excellence in corrosion resistance, this pipeline handles inorganic acids, alkalis, and salts with ease, making it ideal for industrial sewage discharge and transportation.
★ The pipeline features a low friction coefficient, allowing for smooth water flow, reducing the risk of blockages, and minimizing maintenance efforts.
★ Notably, the material has a high oxygen index coupled with self-extinguishing properties, enhancing safety.
★ The pipeline's minimal linear expansion coefficient of 0.07mm/m.ºC ensures negligible deformation due to temperature changes. Its low thermal conductivity and elastic modulus provide superior frost resistance compared to traditional cast iron drainage pipes.
★ Seamless pipe and fittings connection through bonding simplifies construction, offering convenient operations and boosting installation efficiency.
★ Ideal for both industrial and residential building drainage systems, this pipe can handle continuous domestic sewage discharge not exceeding 40ºC and instant discharge up to 80ºC. It is also suitable for non-corrosive industrial wastewater.
Pipe connection
★ Precision in pipe socket connections is achieved by adhering to the following meticulous procedures:
1. Prior to bonding, thoroughly clean both the pipe socket and fitting socket.
2. Accurately measure the socket depth and appropriately mark the pipe port.
3. Apply adhesive, starting with the socket, followed by the fitting. Ensure an even and suitable coating.
4. Align accurately, insert to the marked depth, and rotate by 1/4 turn to secure.
5. Clean any excess adhesive from the socket to maintain a tidy joint.
6. Allow the assembled pipe to stand until the interface is fully cured.
★ For safe adhesive usage, adhere to these key guidelines:
1. Use adhesives and cleaning agents judiciously, restricting use to trained operators only.
2. Maintain a flame-free bonding area with adequate ventilation.
3. Avoid construction below -10ºC, and never use fire to accelerate adhesive curing.
4. Ensure personnel are equipped with protective gloves. In the event of adhesive contact with eyes, rinse immediately with water and seek medical attention.
Installation instructions
Saw pipe and groove:
Carefully determine the pipe's length per layer based on precise measurements and the dimensions of connected fittings. Employ fine tooth saws, cutters, or pipe cutting machines for precise cuts, ensuring a flat, deformation-free section. Create a groove of 15°-30° on the socket area to be bonded, with a length no less than 3mm and a thickness of 1/3 to 1/2 of the pipe wall. Remove all debris post-grooving for a clean finish.
Socket protection:
Post-connection, gently clean excess adhesive with a cotton yarn or dry cloth dipped in detergents like acetone. Allow the joint to stand still until fully cured, adjusting curing time accordingly during winter construction.
