PE管施工通病背后，还有这些优化方向

(1) Towing and dropping of polyethylene pipes during transport, handling and storage resulting in damage to the pipes;

(2) The roller bracket was not used during the welding and non-excavation of the PE tube straight pipe section, resulting in scratches on the PE pipe wall;

(3) Failure to take protective measures such as sun protection and rain protection to protect the pipes stored in the field, affecting the performance of the pipes and shortening the service life of the pipes;

(4) The pipeline after excavation of the lower ditch was not backfilled in time according to regulations, and was covered and soaked by construction waste and rainwater for a long time, affecting the safety and service life of the pipeline;

(5) Pipe and pipe parts themselves do not meet the requirements for quality or use expired pipe and pipe parts.
