【Common Issues in Haichuan Pipeline Design】No local pressure gauge is installed at the pump outlet, or it is not convenient for operation
Thread Content
No local pressure gauge is installed at the pump outlet. In accordance with HG 28559-1993 \"Basic Unit Patterns for Piping and Instrumentation Diagrams\", 3.0.2.1 requires that all pumps must be equipped with at least one local pressure indicator, which should be located between the pump outlet and the first valve. According to clause 8.1.1 of SH/T 3014-2012 \"Design Code for Pumping Areas in Petrochemical Storage and Transportation Systems\", a pressure gauge should be installed at the pump outlet, and it is advisable to install one at the pump inlet as well. A thermometer should be installed at the inlet of the pump used to convey the heating medium. The pressure gauge should be located on the straight pipe section between the pump outlet and the check valve, facing the operating side.
