Recently, a technical team from an international oil company visited Global Valve Group to conduct delivery acceptance for a batch of hydrogen-specific valves in accordance with technical specifications and contract progress requirements.

 Due to hydrogen's flammable and explosive properties, extremely stringent requirements exist for valve sealing and medium control. Hydrogen-specific valves are primarily manufactured from materials such as stainless steel and titanium, offering high strength, corrosion resistance, and low-temperature shock resistance. These valves incorporate specialized designs including unique seat and packing seal structures, while also imposing distinct requirements on raw material chemical composition, physical properties, heat treatment, production processes, and inspection procedures compared to conventional valves.

To ensure this batch of hydrogen-specific valves meets customer and international standards for product quality and performance, both teams agreed to add the following tests: ISO 15848-1 and ISO 15848-2 valve micro-leakage tests, UT and PT non-destructive testing, hydrogen-induced cracking (HIC) tests, and hydrogen sulfide stress corrosion (SSC) tests. All acceptance items passed on the first attempt, confirming this batch of hydrogen-specific valves meets the demanding requirements of its operational environment.

Leveraging its technical expertise in valve engineering, Universal Valve Group is committed to providing comprehensive fluid control solutions for the sustainable development of the clean energy industry, establishing itself as a trusted partner for its customers.
