Three Steps to Stop a Leak in an Emergency
First, shut off the valve upon discovering a leak! Then, temporarily secure the leak point with rubber pads and stainless steel clamps, and finally wipe the surface dry. Note:
Do not touch the high-temperature welded area directly with your hands.
Temporary treatment should not exceed 48 hours.
If the pressure is too high, shut off the system completely.
Professional Solution for Deep Repair
A complete solution requires re-welding:
Cut 5cm from each end of the leaking joint.
Use a dedicated electrofusion sleeve for secondary welding.
Re-weld after cooling for 2 hours.
Key points: Welding temperature should be controlled at 210℃±5℃, and the pressure test should maintain a pressure level of 30 minutes without pressure drop.
Secrets to Preventing Leaks
Remember these three points to avoid leak troubles:
Ensure the pipe ends are free of oil before welding.
Avoid mixing pipe fittings from different brands.
Perform a pipe pressure test annually.
Special reminder: Preheat pipes during winter construction; avoid direct sunlight after welding in summer.
