The common problems and solutions of UPVC pipe are: Pipe bending and deformation

• Cause: during the cooling and shaping process, the cooling rate of the upper and lower parts of the pipe is inconsistent; the sizing sleeve is too short, and the predetermined diameter effect is poor; the traction force of the tractor is unstable.

• Solution: use spray type water tank to make cooling consistent; replace the sizing sleeve with suitable length; use crawler tractor to reduce pipe deformation.
