The technology of hot tapping and plugging under pressure for PE gas pipeline is suitable for the construction of hot tapping and plugging under pressure for Urban Gas PE pipeline. Under the condition of ensuring the normal operation of PE gas pipeline, the construction operations such as adding bypass, replacing or adding valve and replacing pipe section are carried out for PE pipeline. To avoid the economic loss caused by the shutdown of construction operation and the adverse impact on social production and life.
The PE folding sealing element contains a steel framework inside to ensure that the overall strength of the sealing element will not deform under pressure. The sealing lip of the sealing element is equipped with a pressure compensation structure to ensure the tightness of sealing.
