Titanium (TA2/Gr2) is the premier material for seawater service. Its dense oxide film gives nearly zero corrosion in marine environments, making it the top choice for offshore plat... [2026-05-25]
In LNG, ethylene, air separation, and refrigeration systems, valves must withstand -46°C or lower. Standard carbon steel (e.g., WCB) becomes brittle below -29°C, so low-temperatu... [2026-05-22]
Hastelloy (C-276/C-22) is the top material for strong acids, alkalis, and mixed corrosive media. DN65 (2.5″) valves are widely used in chemical, pharmaceutical, and hydrometallurg... [2026-05-08]
A gate valve that seals “bubble‑tight” is ideal, but in real engineering, a certain amount of leakage is allowed. Knowing leakage classes avoids misjudging valve quality and hel... [2026-05-06]
