J-VALVES JB/T 12624-2016 Globe Valves for Liquefied Natural Gas (LNG)

I. Standard Introduction: The Significance of JB/T 12624-2016

JB/T 12624-2016 is a technical standard formulated in China's machinery industry for special valves used in liquefied natural gas (LNG) systems.This standard sets strict requirements for the design, manufacturing, inspection, and performance of valves, ensuring they possess safety, sealing performance, and long-term stability in low-temperature, high-pressure, and flammable environments.

As a professional domestic valve manufacturer, J-VALVES strictly complies with the JB/T 12624-2016 standard. The globe valves specially developed for LNG have been widely applied in key fields such as LNG storage and transportation systems, refueling stations, gasification devices, and low-temperature process pipelines.

II. Structural Features of J-VALVES Globe Valves for LNG

1. Valve Body Material

   Low-temperature alloy steel or austenitic stainless steel is adopted to prevent embrittlement or leakage in low-temperature environments.

2. Valve Seat and Disc Design

   The precision-ground valve seat structure enables tight sealing, effectively preventing gas leakage.

3. Low-Temperature Extension Stem Design

   The specially extended stem structure avoids the transfer of low temperatures to the driving end, improving operational safety and service life.

4. Compact Structure and Easy Maintenance

   The modular design facilitates on-site installation and maintenance, making it suitable for LNG storage tanks, transportation pipelines, and loading/unloading systems.
