Uneven cutting end face of heat-resistant polyethylene pipes
Problem Phenomenon
After cutting, the pipe end face has burrs, inclination or chipping.
Uneven cutting end face affects pipe connection quality and may cause leakage in welding and socket connections.
Cause Analysis
(1) Cutting tool worn or cutting edge not sharp
(2) Cutting speed too fast or cutting pressure too large
(3) Pipe temperature too high, deforms during cutting
(4) Cutting machine improperly installed, cutter not perpendicular to the pipe
(5) Pipe wall thickness uneven, uneven force during cutting
Solution
(1) Replace or sharpen the cutting tool
(2) Adjust cutting speed and pressure to ensure smooth cutting
(3) Ensure the pipe is fully cooled before cutting
(4) Correct the cutting machine installation, cutter perpendicular to the pipe axis
(5) Ensure uniform pipe wall thickness
Key Takeaway
Uneven cutting end face is caused by tool wear or improper cutting parameters, and tools need to be maintained and cutting process optimized.
