★ Designed for longevity, these pipes boast exceptional aging resistance, with a service life exceeding 50 years.
★ Perfect for industrial applications, our pipes excel in resisting corrosion from inorganic acids, alkalis, and salts, making them ideal for sewage discharge and transportation.
★ With a low friction coefficient, our pipes deliver smooth water flow, minimizing the chances of blockages and reducing maintenance requirements.
★ Crafted from material with a high oxygen index, our pipes feature self-extinguishing properties for enhanced safety.
★ With a minimal linear expansion coefficient and superior frost resistance, our pipes outperform traditional cast iron pipes, offering minimal deformation due to temperature changes.
★ Simplifying installation, our pipe and fitting connections can be easily bonded, ensuring a straightforward, efficient installation process.
★ Ideal for both industrial and residential drainage projects, our pipes handle continuous sewage discharge up to 40ºC and withstand instant temperatures as high as 80ºC. They are also suitable for non-corrosive industrial wastewater.
Pipe connection
★ Follow these meticulous steps for perfect pipe socket connections:
1. Thoroughly clean both the pipe socket and fitting socket before applying any adhesive.
2. Measure the socket depth and accurately mark the pipe port accordingly.
3. Apply adhesive evenly, starting with the socket, then proceed to the socket fitting, ensuring a uniform coat.
4. Align precisely, insert into the marked section in one swift motion, then gently rotate 1/4 turn for secure fit.
5. Clean any excess adhesive from the socket area immediately.
6. Allow the bonded pipe to stand undisturbed until the joint has fully cured.
★ Adhere to these safety regulations for adhesive use:
1. Use adhesives and cleaning agents judiciously. Restrict usage to trained personnel only.
2. Ensure no open flames are present at the bonding site, and maintain ample ventilation.
3. Avoid construction in temperatures below -10ºC, and never use fire to heat adhesive points.
4. Equip workers with gloves. If adhesive contacts eyes, rinse thoroughly with water and seek immediate medical attention.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length based on precise measurements and fitting dimensions. Use fine tooth saws, cutters, or pipe cutting machines for a clean, deformation-free cut. The socket area should be grooved at a 15°-30° angle using a medium file, with a groove length of at least 3mm and thickness 1/3-1/2 of the wall. Clear debris post-grooving.
Socket protection:
Post-socket connection, cleanse excess adhesive using cotton or a dry cloth with a mild detergent like acetone. Allow static curing based on adhesive performance and climate. Extend curing times for winter constructions.
