Are there any relevant regulations?
In accordance with Article 23 of the Regulations on Safe Production in the Oil and Gas Industry, valves shall be configured, installed, and used as specified, in compliance with safety technical requirements. Meanwhile, in accordance with Article 24 of the “Safety Regulations for Oil and Natural Gas Exploration” (GB/T 19482-2004), valves on pipelines shall be installed as specified in the design drawings, so as to ensure the normal operation, maintenance, and shutdown of the pipelines.
