Thread Content

Witnessing the decade-long rapid development of chemical processing equipment, I praise the prosperity and strength of modern China. Wishing everyone a happy New Year, and may their families enjoy peace and health. By contributing our ideas, we can create a more lively atmosphere; HaiChuan becomes even better with your participation. Everyone is welcome to join in the forum discussions. --------------- In June 2022, Shanghai Hudong Shipbuilding Valve Co., Ltd. made a breakthrough through independent innovation by successfully developing large-diameter, ultra-low temperature hydraulic globe valves for LNG ships, thus creating a complete product series whose performance ranks among the best in the world. This type of valve is a key component in the ultra-low temperature liquid cargo systems of LNG carriers. It features low-temperature resistance, operation over a wide temperature range, low leakage, and a long service life. Its operating temperature is -163°C, while the test temperature is -196°C; it has also passed ultra-high reliability tests under alternating temperature conditions, fully meeting the international standards BS6364 and ISO15848.
