Recently, a technical team of a foreign oil company visited Huanqiu Valve Group to deliver and accept a batch of hydrogen-specific valves in accordance with technical requirements and contract performance progress. Due to the flammable and explosive nature of hydrogen medium, there are extremely high requirements for valve sealing and medium control. Hydrogen-specific valves are mainly made of stainless steel, titanium and other materials, with the characteristics of high strength, corrosion resistance, low temperature and shock resistance. Hydrogen-specific valves are designed with special valve seats and packing sealing structures, and at the same time, they have special requirements for the chemical composition, physical properties, heat treatment, production and inspection processes of raw materials that are different from conventional valves. In order to ensure that the product quality and performance of this batch of hydrogen-specific valves meet the requirements of customers and international standards, the two teams negotiated and decided to add 22.8MPa helium sealing test, ISO15848-1 and ISO15848-2 valve micro-leakage test, UT and PT non-destructive testing, hydrogen-induced cracking test (HIC), hydrogen sulfide stress corrosion test (SSC) and other comprehensive inspection links, and all acceptance items were qualified at one time to ensure that this batch of hydrogen-specific valves delivered meet the stringent requirements of the use conditions. With its accumulated technology in the valve field, Huanqiu Valve Group is committed to providing comprehensive fluid control solutions for the sustainable development of the clean energy industry and becoming a trusted partner of customers.
