Pipe connection
★ Follow these precise procedures for seamless pipe socket connections:
1. Thoroughly clean the pipe and fitting sockets before bonding to ensure a secure fit.
2. Accurately measure and mark the socket depth for precise pipe port insertion.
3. Apply adhesive evenly, starting with the socket and then the pipe, ensuring uniform coverage.
4. Align accurately, insert swiftly to the marked depth, and rotate 1/4 turn for optimal bonding.
5. Carefully remove excess adhesive from the socket to maintain cleanliness.
6. Allow the bonded pipe to stand undisturbed until fully cured for optimal performance.
★ Adhere to these essential safety guidelines when using adhesives:
1. Utilize adhesives and cleaners only as required, restricting use to authorized personnel.
2. Maintain excellent ventilation and avoid open flames at the bonding site.
3. Avoid construction below -10ºC and refrain from using fire to dry adhesive points.
4. Equip personnel with gloves, and in case of eye contact with adhesive, rinse immediately with water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine saw pipe length meticulously, layer by layer, ensuring precise measurements aligned with connected fittings. Utilize fine tooth saws, cutters, or pipe cutting machines for flawless cuts without deformation. Groove socket areas at a 15°-30° angle for optimal adhesion, with lengths not less than 3mm and thickness 1/3-1/2 of the wall. Clear debris post-grooving for optimal adhesion.
Socket protection:
Post-connection, gently cleanse extruded adhesive using cotton or cloth moistened with acetone or similar. Let rest until cured, observing adhesive properties and climate. Extend curing in winter for best results.
