Pipeline Installation Tips

1. Cold Weather Bonding:

– Avoid bonding in the morning and evening.

– Store glue in a warm place for better fluidity.

– Dry pipes and fittings before bonding.

– Sun-dry pipes and fittings if possible.

– In cold temperatures, drying time is longer. After drying, conduct a pressure test.

– Connect pipelines in sections during cold weather to minimize joint movement.

– Read and follow bonding technology instructions carefully before installation.

2. Hot Weather Bonding:

– Store glue in a cool, ventilated indoor area.

– Install pipes in the morning.

– Wipe joints with a damp cloth before bonding for a cooler surface.

– Ensure glue surface is wet during bonding, especially for large-diameter pipes.

– Use high-viscosity glue for slower drying and longer bonding time.

– Cap the glue bottle promptly after use.

Flange connections must adhere to specific criteria:

1. When using transition pieces to link pipes, valves, and other accessories made of different materials, the joint structure at both ends of the transition piece should match the joints at both ends.

2. The flange’s bolt-hole diameter and center distance must align with those of the connected valve and accessories.

3. CPVC flanges connecting to metal flanges should be installed in a straight line with supports to prevent harmful stress on the CPVC flange during installation. Ensure the flange contact surface is flat before installing bolts.
