Pipe connection
★ Ensure a flawless pipe socket connection by meticulously following these essential procedures:
1. Clean the pipe socket and fitting socket thoroughly before applying any adhesive.
2. Accurately measure the socket depth and mark it clearly on the pipe end.
3. Apply the adhesive evenly, covering the socket first followed by the pipe end, ensuring a uniform coating.
4. Align the components precisely, insert them to the marked depth, and rotate a quarter turn to secure the bond.
5. Carefully remove any excess adhesive from the socket for a clean finish.
6. Allow the bonded pipe to stand undisturbed until the adhesive has fully cured.
★ Adhere to these safety guidelines for the safe usage of adhesives:
1. Utilize adhesives and cleaning agents responsibly, ensuring only trained personnel handle them.
2. Maintain a flame-free environment at the bonding site and ensure adequate ventilation.
3. Avoid construction in temperatures below -10ºC, and refrain from using open flames to dry adhesive points.
4. Equip construction personnel with gloves for protection. In case of adhesive contact with eyes, rinse immediately with plenty of water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length based on precise measurements and the dimensions of connecting fittings. Use fine tooth saws, cutters, or pipe cutting machines for precision. Ensure a flat section without deformation, and file socket areas to a 15°-30° groove using a medium board file. Maintain a groove length of at least 3mm, with groove thickness at 1/3-1/2 of the pipe wall. Remove debris post-grooving for a clean finish.
Socket protection:
After socket connection, gently clean excess adhesive using cotton yarn or a dry cloth with a small amount of solvent like acetone. Allow the connection to cure according to adhesive performance and climate. Extend curing time during winter construction for optimal results.
