The accuracy issue of pressure gauges in the hydrostatic testing of long-distance natural gas pipeline projects
Thread Content
According to the pressure testing provisions of GB50369-2014, there are clear requirements regarding the accuracy and range of pressure gauges used for pneumatic testing. However, the pressure gauge for the hydrostatic test is not specified in any regulations.
At the same time, GB16805 only specifies that pressure sensing and display devices require a pressure range and incremental scale necessary for testing pressures. However, the accuracy level is not specified.
This situation occurs because of inconsistencies such as differing perspectives among the experts involved in the development process of various standards (the content may not be identical). Therefore, I believe it is better to adhere to high standards in order to avoid disputes in engineering projects.
