Effect is resisted.After PE pipe-line system is using welding process connection, connector leakage will not occur for the resistance to end load of connector.Meanwhile PE is answered
Power relaxation property effectively can consume stress by deformation, therefore, in joint and knee, do not need in most cases into
The anchoring of row somewhat expensive.But existing electric melting pipe fittings are easy to damaged electric leakage in power connector end setting position protrusion, separately
Outside, divide the uniformly distributed electrothermal conductor in pipe material inner wall, so that its mechanical property of pipe laying is easier stress, temperature and time
Etc. factors influence, there is the phenomenon that stress relaxation, in addition, the creep and relaxation deformation of long pipeline can reduce its performance.
