Features
★ Immerse yourself in the superior quality of our Heavy-Duty PVC Fittings. Crafted with impeccable surface hardness and outstanding tensile strength, these fittings ensure a remarkably high safety factor for every pipeline.
★ Revel in the longevity of our product, designed with excellent aging resistance to provide you with more than 50 years of dependable service.
★ Engineered with superior corrosion resistance against inorganic acids, alkalis, and salts, this pipeline is your ideal solution for industrial sewage discharge and transport needs.
★ The pipeline’s minimal friction coefficient ensures a smooth, unimpeded water flow, drastically reducing the likelihood of blockages and minimizing maintenance efforts.
★ Crafted from a material boasting a high oxygen index, these fittings offer self-extinguishing capabilities for added safety and peace of mind.
★ Designed with a small linear expansion coefficient of just 0.07mm/m.ºC, our pipeline guarantees minimal deformation from temperature changes. Its low thermal conductivity and elastic modulus enhance frost resistance, outperforming traditional cast iron drainage pipes.
★ Benefit from the simplicity of bonded pipe and fitting connections, offering straightforward installation, ease of operation, and elevated installation efficiency.
★ Perfect for both industrial and civil building drainage projects, these pipes can handle continuous domestic sewage temperatures up to 40ºC and instant sewage discharges up to 80ºC. Ideal for non-corrosive industrial wastewater applications.
Pipe connection
★ Ensure a secure pipe socket connection by following these precise procedures:
1. Clean the pipe and fitting sockets meticulously before beginning the bonding process.
2. Accurately measure the socket depth and mark the pipe port for perfect alignment.
3. Apply the adhesive methodically: coat the socket first, then the pipe socket, ensuring an even and adequate coverage.
4. Align the directions meticulously; insert the pipe to the marked section in one go, followed by a 1/4 turn rotation for secure fitment.
5. Clear any excess adhesive from the socket to maintain a clean finish.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured for optimal performance.
★ Ensure the safe usage of adhesives by adhering to these essential guidelines:
1. Use adhesives and cleaning agents sparingly, and restrict access to non-operators for safety.
2. Maintain an open-flame-free environment at the bonding site, ensuring proper ventilation throughout the process.
3. Avoid construction at temperatures below -10ºC, and refrain from using fire to speed up adhesive curing.
4. Equip personnel with protective gloves. In case of accidental eye contact with adhesive, rinse immediately with copious amounts of water and seek medical attention promptly.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length with precision for each layer, using exact measurements and the dimensions of connected fittings. Opt for fine-tooth saws, cutters, or pipe cutting machines to achieve a perfectly flat fracture with no deformation. File a 15°-30° groove on the socket with a medium board file, ensuring a length of at least 3mm and a thickness between 1/3 to 1/2 of the pipe wall. Clear away debris post-groove for a pristine finish.
Socket protection:
Post-connection, cleanse the socket area using cotton yarn or a dry cloth with a touch of acetone-based detergent. Let it remain static until fully cured, as per adhesive properties and climate. Extend curing time appropriately during winter installations for optimal durability.
