It has been widely used in various gas pipelines such as city gas, liquefied petroleum gas, natural gas and oxygen, and has been highly praised and paid attention by market users. What are the industry standards for gas valves? Gas valves are a new type of safety matching device for gas pipeline engineering. They have been widely used in various gas pipelines such as city gas, liquefied petroleum gas, natural gas and oxygen. User's respect and attention. What are the industry standards for gas valves? Gas valves occupy an important position in the gas industry. The Ministry of Construction attaches great importance to the normative construction of gas valves. Since the 1980s, gas valves have compiled industry standards, including CJ3005-1992. "General Technical Requirements for Gray Cast Iron Valves for Urban Gases", CJ3055-1995 "Tests and Inspections for Valves for Town Gases", CJ3056--1995 "General Technical Conditions for Ductile Iron and Cast Steel Valves for Town Gases", 2002 In June, the industry standard for "Manual Manual Gas Valves" was passed. The formulation and promulgation of these standards have regulated the valve industry, promoted the progress and development of gas valves, and promoted the development of the gas industry; provided reference for the development, production, and use of units; improved understanding of the difference between gas valves and general valves , to ensure the safety margin of gas valves; welcomed by gas peers
