Pipe connection
★ Follow these meticulous pipe socket connection procedures to ensure optimal performance:
1. Thoroughly clean the pipe socket and fitting socket before the bonding process.
2. Accurately measure the socket depth and clearly mark the pipe port.
3. Apply adhesive uniformly, starting with the socket followed by the fitting, ensuring even coverage.
4. Precisely align and insert into the marked area, executing a 1/4 turn for secure fit.
5. Clean any excess adhesive from the socket with care.
6. Maintain the bonded structure in a standing position until the interface fully cures.
★ Adhere to these safety guidelines when using adhesives to ensure a secure working environment:
1. Only authorized personnel should use adhesives and cleaning agents as needed.
2. Ensure a flame-free environment at the bonding site with adequate ventilation.
3. Avoid construction in temperatures below -10ºC and do not use fire to dry adhesive points.
4. Wear gloves during construction. In case of accidental eye contact, rinse immediately with ample water and seek medical attention.
Installation instructions
Saw pipe and groove:
Accurately determine pipe length per layer using measured data and connected fitting dimensions. Employ fine-tooth saws, cutters, or pipe machines for clean cuts. Ensure no deformation occurs. Prepare socket areas by filing a 15°-30° groove, ensuring its length and thickness adhere to specified guidelines. Clear away debris after grooving for optimal adhesion.
Socket protection:
Post-connection, cleanse excess adhesive using cotton yarn or cloth with acetone or similar, allowing static cure based on adhesive type and weather. Extend curing time suitably for winter projects.
