Features
★ Boasting remarkable surface hardness and superior tensile strength, these pipes offer outstanding durability, ensuring a high safety factor for diverse pipeline applications.
★ With exceptional resistance to aging, these pipelines promise a reliable service life that can extend beyond 50 years, guaranteeing long-term performance.
★ The pipelines excel with exceptional corrosion resistance against inorganic acids, alkalis, and salts, making them ideal for industrial sewage transport and discharge systems.
★ Benefit from a low friction coefficient that ensures smooth water flow with minimal blockages, reducing maintenance efforts significantly.
★ Crafted from material with high oxygen index, these pipes boast excellent self-extinguishing capabilities for enhanced safety.
★ A small linear expansion coefficient ensures minimal deformation from temperature changes, complemented by low thermal conductivity and elastic modulus, offering superior frost resistance compared to traditional cast iron pipes.
★ Experience hassle-free installation with pipes and fittings that bond easily, allowing for a simple construction method that enhances operational convenience and installation efficiency.
★ Perfectly suited for both industrial and civil drainage projects, these pipes handle continuous domestic sewage at temperatures up to 40ºC, and can withstand instant discharges up to 80ºC, also accommodating non-corrosive industrial wastewater.
Pipe connection
★ Ensure optimal pipe socket connections by strictly adhering to the following meticulous procedures:
1. Clean the pipe socket and fitting socket thoroughly before bonding to ensure a secure fit.
2. Accurately measure the socket depth and clearly mark the pipe port for precise alignment.
3. Apply adhesive uniformly, starting with the socket and then the pipe, for an even coating that ensures secure bonding.
4. Align accurately, insert swiftly to the marked depth, followed by a 1/4 turn rotation for secure engagement.
5. Clean any excess adhesive from the socket to maintain a neat finish.
6. Allow the bonded pipe to stand until the interface is fully cured, ensuring a strong and durable connection.
★ Safely utilize adhesives by adhering to these critical safety provisions:
1. Use adhesives and cleaning agents only as needed, restricting their use to qualified operators.
2. Maintain a flame-free environment at bonding sites and ensure adequate ventilation.
3. Avoid construction in temperatures below -10ºC and refrain from using open flames to heat adhesive points.
4. Equip construction personnel with gloves, and in case of eye contact, rinse with plenty of water and seek immediate medical attention.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length layer by layer based on precise measurements and connected fittings dimensions. Employ fine-tooth saws, cutters, or pipe cutting machines for clean cuts. The cut must be flat with no deformation. File the socket groove into a 15°-30° angle, ensuring it is not less than 3mm in length and 1/3-1/2 of the wall thickness. Clean debris thoroughly post-grooving.
Socket protection:
After connection, cleanse the extruded adhesive using cotton yarn or a dry cloth moistened with detergents like acetone. Allow the connection to remain static until the adhesive cures, adjusting curing times as necessary for winter conditions.
