Description

TECHNICAL FIELD

Traditional large-diameter pipe coiling mainly relies on manual operation, which has the problems of low efficiency, high labor intensity, unstable coiling quality, etc. Especially for high-pressure pipes, which are rigid and have strong resilience, manual coiling is easy to cause pipe deformation, surface damage or stress concentration, affecting the mechanical properties and service life of the pipes.
