Design issues of return pipes in the LPG storage and distribution station construction process
Thread Content
At LPG storage and distribution stations, the safety return flow on the hydrocarbon pump outlet pipeline returns to a separate inlet of the storage tank through a return pipe. The earliest specifications did not mention the need to install a safety return valve at the pump outlet. Is it feasible to have the safety return valve at the outlet lead back to the liquid inlet of the storage tank, without using a separate return pipe? Is there any specification that mentions the need to design a separate safety return pipe?
The purpose of this setting is to prevent damage to the pipes caused by excessive pressure in the pipeline network resulting from the activation of the pump.
