★ Designed with minimal thermal impact in mind, our pipes have a small linear expansion coefficient of just 0.07mm/m.ºC, offering enhanced frost resistance and outperforming traditional cast iron drainage alternatives.
★ Simplify your installation process with our easy-to-use bonding method for pipe and fittings, promising straightforward operations and high installation efficiency.
★ Suitable for both industrial and residential projects, our drainage pipes can handle continuous sewage discharge up to 40ºC, withstanding instant discharges up to 80ºC, and are perfect for non-corrosive industrial waste.
Pipe connection
★ Ensure a secure connection by following these meticulous pipe socket procedures:
1. Prior to bonding, meticulously clean both the pipe socket and fitting socket to ensure a flawless connection.
2. Accurately measure the socket depth and clearly mark the pipe port for precise alignment.
3. With care, apply adhesive by initially coating the socket, followed by the pipe end, ensuring an even and adequate coverage.
4. Align and insert confidently, engaging the marking in a single motion, then twist a quarter turn for a secure fit.
5. Neatly remove any adhesive residue from the socket to maintain a clean and professional finish.
6. Allow the bonded pipe to stand undisturbed until the interface achieves complete curing, ensuring a strong and lasting bond.
★ Adhere to these crucial safety guidelines for adhesive use:
1. Limit adhesive and cleaning agent use to essential personnel only, preventing non-authorized handling.
2. Maintain a flame-free environment at the bonding point, ensuring optimal ventilation for safety.
3. Avoid construction under -10ºC and refrain from using fire to expedite adhesive curing.
4. Equip construction teams with gloves for protection. If adhesive contacts the eyes, rinse thoroughly with water and seek immediate medical attention.
Installation instructions
Saw pipe and groove:
Determine saw pipe lengths meticulously using detailed measurements and connected fitting dimensions. Choose precise tools like fine-toothed saws, cutters, or pipe cutting machines. Ensure smooth cuts and avoid deformation. Create a groove at a 15°-30° angle, maintaining a length of at least 3mm, and a thickness of 1/3-1/2 of the pipe wall. After grooving, clean all debris for optimal adhesive bonding.
Socket protection:
Post-connection, gently wipe away excess adhesive using cotton yarn or clean cloth with a mild detergent, like acetone. Allow the interface to cure in static conditions suitable to adhesive properties and climate. Extend curing times during winter construction for safety and efficacy.
