Features
★The surface hardness and tensile strength of the pipe are outstanding, ensuring a high safety factor for the pipeline.
★With exceptional aging resistance, our pipes boast a service life exceeding 50 years.
★Exceptional corrosion resistance to inorganic acids, alkalis, and salts, making our pipes ideal for industrial sewage discharge and transportation.
★Low friction coefficient ensures smooth water flow, reducing the likelihood of blockages and minimizing maintenance efforts.
★The material features a high oxygen index and self-extinguishing properties, enhancing safety.
★The linear expansion coefficient is minimal at 0.07mm/m.ºC, offering superior resistance to temperature-induced deformation. Enhanced frost resistance compared to cast iron drainage pipes.
★Pipes and fittings can be bonded easily, simplifying construction, enhancing convenience, and boosting installation efficiency.
★Perfect for industrial and civil building indoor and outdoor drainage projects, handling domestic sewage temperatures up to 40ºC continuously and up to 80ºC instantaneously. Suitable for industrial wastewater that does not corrode the pipe.
Pipe connection
★Follow these precise steps for pipe socket connections:
1. Clean the pipe socket and fitting socket thoroughly before bonding.
2. Measure socket depth and mark the pipe port accurately.
3. Apply adhesive uniformly, starting with the socket and then the pipe fitting socket.
4. Align direction, insert to the marked depth at once, and rotate 1/4 turn.
5. Wipe off any excess adhesive from the socket.
6. Allow the bonded pipe to stand until the interface cures completely.
★Adhesive safety measures include the following:
1. Use adhesives and cleaning agents as needed, restricting use to operators only.
2. Ensure no open flames near bonding points and maintain good ventilation.
3. Avoid construction below -10ºC and refrain from using fire to bake adhesive points.
4. Wear gloves during construction. If adhesive contacts eyes, rinse with plenty of water and seek hospital treatment immediately.
Installation instructions
Saw pipe and groove:
Determine saw pipe length based on measured dimensions and connected pipe fittings. Use fine-tooth saws, cutters, or pipe cutting machines. Ensure flat fracture with no deformation. File the socket area to a 15°-30° groove, with a length of at least 3mm and a thickness of 1/3 to 1/2 of the pipe wall. Remove debris after grooving.
Socket protection:
After connecting the socket, clean extruded adhesive with cotton yarn or a dry cloth dipped in detergent like acetone. Allow it to stand until the interface is fully cured, adjusting curing time for winter conditions.
