Pipe production line is used to make multi-layer HDPE petrol pipe for gasoline petrol station underground pipeline system. Pipe structure is pipe in pipe, double wall type. Primary pipe is a five layer HDPE EVOH pipe, and secondary pipe is a two layer HDPE pipe.
The Petrol Pipe System is the most compact, advanced and installer friendly single and double-wall piping system. The secondary contained pipes have been developed to provide extra environmental safety. By applying an secondary pipe over the inner primary pipe, an interstitial space is created. A leak detection system can then be used to monitor the interstitial space for leaks.
