Features
★ Experience superior durability with our pipes, crafted with outstanding surface hardness and tensile strength, ensuring a heightened level of pipeline safety.
★ Enjoy longevity with pipes that boast exceptional aging resistance, promising a reliable service life exceeding 50 years.
★ Our pipelines demonstrate remarkable resistance to corrosion from inorganic acids, alkalis, and salts, making them ideal for industrial sewage discharge and transport.
★ Benefit from minimal friction thanks to the pipeline's sleek surface, guaranteeing smooth water flow, reduced clogging, and minimal maintenance requirements.
★ The material's high oxygen index and self-extinguishing properties offer an added layer of safety and performance.
★ With a minimal linear expansion coefficient of 0.07mm/m.ºC, our pipelines present negligible thermal deformation and superior frost resistance compared to cast iron drainage pipes.
★ The simplicity of pipe and fitting connections through bonding enables straightforward construction, convenient operation, and heightened installation efficiency.
★ Perfect for both industrial and civil indoor and outdoor drainage projects, our pipes manage continuous domestic sewage at temperatures up to 40ºC and instantaneous discharges up to 80ºC, along with non-corrosive industrial wastewater.
Pipe connection
★ Adherence to the following procedure is crucial for effective pipe socket connection:
1. Thoroughly clean both the pipe socket and fitting socket prior to bonding.
2. Accurately measure the socket depth and clearly mark the pipe port.
3. Apply adhesive, first to the socket, then the pipe, ensuring an even and sufficient coating.
4. Align properly, insert promptly to the marked depth, then twist 1/4 of a turn for optimal fit.
5. Neatly wipe away any excess adhesive from the socket area.
6. Allow the bonded pipe to stand until the adhesive interface is fully cured.
★ Adhere to safety guidelines for adhesive usage as follows:
1. Utilize adhesives and cleaning agents as needed; unauthorized personnel should refrain from use.
2. Ensure no open flames are present in the bonding area and maintain adequate ventilation.
3. Avoid construction below temperatures of -10ºC and refrain from using open flames to dry adhesive points.
4. Equip construction personnel with gloves, and in case of adhesive contact with eyes, flush with water immediately and seek medical aid.
Installation instructions
Saw pipe and groove:
The length of the saw pipe is precisely determined per layer based on exact measurements and the dimensions of each connecting fitting. Utilize fine-tooth saws, cutters, and pipe cutting machines for optimal results. Ensure a smooth, distortion-free cut. The socket section for bonding can be filed at a 15°-30° angle using a medium board file. A minimum groove length of 3mm is recommended, with a groove thickness of 1/3 to 1/2 of the pipe wall. Remove any debris post-grooving.
Socket protection:
Post-connection, cleanse the extruded adhesive using cotton yarn or a dry cloth lightly soaked in a detergent like acetone. Allow the interface to remain static until cured, considering adhesive performance and climate. Extend curing time appropriately during winter conditions.
