Random copolymer polypropylene pipe cut end face uneven
Problem Phenomenon
After cutting, the pipe end face has burrs, is tilted or chipped.
An uneven cut end face affects pipe connection quality and may cause leakage in welding and socket connections.
Cause Analysis
（1）The cutting tool is worn or the cutting edge is not sharp\
（2）Cutting speed too fast or cutting pressure too large\
（3）Pipe temperature too high, deforming during cutting\
（4）The cutting machine is improperly installed, the cutter is not perpendicular to the pipe\
（5）Pipe wall thickness uneven, cutting force uneven
Solution
（1）Replace or sharpen the cutting tool\
（2）Adjust the cutting speed and pressure, ensure smooth cutting\
（3）Ensure the pipe is fully cooled before cutting\
（4）Correct the cutting machine installation, the cutter perpendicular to the pipe axis\
（5）Ensure uniform pipe wall thickness
Key Takeaway
Uneven cut end faces are caused by tool wear or improper cutting parameters, requiring tool maintenance and cutting process optimization.
