Features
★ The surface hardness and tensile strength of the pipe are truly exceptional, offering a robust and reliable construction that significantly enhances the pipeline safety factor for users.
★ Remarkably resistant to aging, these pipes boast a normal service life exceeding 50 glorious years, ensuring long-lasting performance and durability.
★ Outstanding corrosion resistance against inorganic acids, alkalis, and salts makes this pipeline ideal for industrial sewage discharge and transportation, promising unparalleled durability.
★ With a low friction coefficient, the pipeline ensures smooth water flow, minimizing blockages and significantly reducing maintenance workloads.
★ The material is designed with a high oxygen index and has self-extinguishing properties, enhancing safety and reliability.
★ Featuring a small linear expansion coefficient of 0.07mm/m.ºC, this pipeline exhibits minimal deformation due to temperature changes. Its low thermal conductivity and elastic modulus contribute to superior frost resistance compared to traditional cast iron drainage pipes.
★ The pipe and fittings are easily bonded, simplifying construction methods and operations, thereby significantly boosting installation efficiency.
★ Perfect for industrial and civil building indoor and outdoor drainage pipeline projects. It can handle the continuous discharge of domestic sewage at temperatures up to 40ºC, and instantaneous discharges up to 80ºC. Suitable for industrial wastewater that does not corrode the pipe.
Pipe connection
★ To ensure a perfect pipe socket connection, adherence to the following procedural steps is essential:
1. Clean the pipe socket and pipe fitting socket thoroughly before beginning the bonding process.
2. Accurately measure the depth of the socket and mark the pipe port to ensure precision.
3. Apply the adhesive methodically: begin with the socket, then the pipe fitting socket, ensuring an even and appropriate coating.
4. Carefully align, then insert into the marked section in one smooth motion, rotating a quarter turn to secure.
5. Remove any adhesive residue from the socket for a clean finish.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured.
★ Safe use of adhesives is paramount and should comply with these critical guidelines:
1. Adhesives and cleaning agents must be used judiciously, and should only be handled by trained operators.
2. Ensure no open flames are present at the bonding site, and maintain excellent ventilation throughout the process.
3. Avoid construction at temperatures below -10ºC, and never use fire to hasten the adhesive setting.
4. Construction personnel should wear protective gloves. In case of adhesive contact with eyes, rinse immediately with abundant water and seek medical attention promptly.
Installation instructions
Saw pipe and groove:
The length of the saw pipe should be determined precisely, taking into account each connected pipe fitting. Use tools such as a fine-tooth saw, cutter, and pipe cutting machine for perfect cuts. Ensure the cut is flat and free from deformation. File the socket area to a 15°-30° groove with a medium board file, ensuring a groove length of at least 3mm, with thickness between 1/3-1/2 of the pipe wall thickness. Remove debris after grooving for optimal bonding.
Socket protection:
After socket connection, clean any extruded adhesive using cotton yarn or a dry cloth slightly moistened with a solvent like acetone. Allow it to static cure according to adhesive performance and climate. During winter, extend the curing time adequately to ensure complete bonding.
