★ Featuring a minimal linear expansion coefficient of just 0.07mm/m.ºC, our pipelines demonstrate minimal deformation due to temperature changes. With low thermal conductivity and an impressive elastic modulus, they offer superior frost resistance compared to traditional cast iron pipes.
★ Simplify your installation process with our user-friendly pipe and fittings connections. Efficient bonding methods ensure easy operations and high installation efficiency, saving you time and effort.
★ Suitable for a multitude of applications, our pipelines excel in both industrial and civil building projects. They handle indoor and outdoor drainage effortlessly, accommodating domestic sewage temperatures up to 40ºC continuously and instant discharge temperatures up to 80ºC. Ideal for industrial wastewater that poses no corrosion risk to the pipe.
Pipe Connection: Achieve seamless integration with our expertly designed connection procedures, ensuring optimal performance and reliability for your piping systems.
★ Meticulous Pipe Socket Connection: Follow these precise procedures to ensure a secure and effective bond for your piping network.
1. Begin by thoroughly wiping both the pipe socket and fitting socket clean, setting the stage for a flawless bond.
2. Accurately measure the socket depth and carefully mark the pipe port for precise alignment and connection.
3. Apply the adhesive meticulously, starting with the socket and then the pipe, ensuring an even and adequate coating for a robust bond.
4. Align the components accurately, insert them into the marked section in one swift movement, and execute a 1/4 turn rotation for optimal adhesion.
5. With precision, remove any excess adhesive from the socket, ensuring a clean and professional finish.
6. Allow the bonded pipe to stand until the interface is thoroughly cured, ensuring a durable and long-lasting connection.
★ Adhering to Safe Adhesive Practices: Ensure safety and optimal performance by following these guidelines for the use of adhesives.
1. Use adhesives and cleaning agents judiciously, restricting their use to operators only to maintain safety and resource efficiency.
2. Maintain a safe workspace by eliminating open flames and ensuring excellent ventilation at the bonding site.
3. Avoid construction in temperatures below -10ºC, and refrain from applying direct heat to adhesive points to preserve bond integrity.
4. Equip construction personnel with gloves for protection, and promptly address any adhesive exposure to eyes with thorough flushing and medical attention if necessary.
Installation Instructions: Master the art of installing our PVC fittings with clear and detailed steps, ensuring a flawless setup every time.
Saw Pipe and Groove: Execute precision sawing and grooving for an impeccable installation.
Determine the saw pipe length meticulously, using precise measurements and dimensions for each connected fitting. Opt for fine tooth saws, cutters, and specialized pipe cutting tools for precision. Ensure a flat, deformation-free cut. File the socket area to a 15°-30° groove, ensuring a groove length of no less than 3mm, with thickness at 1/3-1/2 of the pipe wall. Post-grooving, eliminate debris for a clean surface.
Socket Protection: Safeguard your connections with meticulous attention to detail.
After socket connection, cleanse extruded adhesive using cotton yarn or a dry cloth with a touch of detergent like acetone. Allow it to remain static until cured, adjusting for adhesive performance and climate conditions. In winter, extend curing time as necessary for optimal bonding results.
