1. Kev Thauj Mus Los Hnyav Zog Tshiab
Kev lag luam, muaj zog duplexcov hlau tsis xebthiab cov thav duab roj teeb tau ua tiav hauv cov tsheb thauj khoom hnyav tshiab, daws cov teeb meem xeb thiab qaug zog uas cov hlau carbon ib txwm ntsib hauv cov av noo siab, cov chaw ntug dej hiav txwv uas muaj xeb heev. Nws lub zog tensile siab dua 30% dua li cov hlau Q355 ib txwm muaj, thiab nws lub zog tso zis siab dua 25%. Nws kuj ua tiav qhov tsim qauv sib dua, txuas lub neej thav duab thiab ua kom lub thav duab roj teeb raug thaum hloov roj teeb. Yuav luag 100 lub tsheb thauj khoom hnyav hauv tsev tau ua haujlwm hauv Ningde thaj chaw lag luam ntug dej hiav txwv tau 18 lub hlis yam tsis muaj kev hloov pauv lossis xeb. Kaum ob lub tsheb thauj khoom hnyav uas muaj thav duab no tau raug xa tawm txawv teb chaws thawj zaug.

2. Cov Khoom Siv Khaws Cia thiab Thauj Khoom Siv Hydrogen
Jiugang lub S31603 (JLH) austenitic stainless hlau, tau ntawv pov thawj los ntawm National Special Inspection Institute, yog tsim tshwj xeeb rau kev siv rau hauv cov kua hydrogen/kua helium (-269 ° C) cryogenic pressure vessels. Cov khoom siv no tswj tau qhov zoo heev, muaj zog cuam tshuam, thiab tsis tshua muaj kev cuam tshuam rau hydrogen embrittlement txawm tias nyob rau hauv qhov kub qis heev, ua kom tiav qhov sib txawv ntawm cov hlau tshwj xeeb hauv Northwest Tuam Tshoj thiab txhawb kev tsim cov kua hydrogen cia tank tsim hauv tsev.

3. Kev Tsim Kho Hluav Taws Xob Loj

Qhov project hydropower ntawm tus dej Yarlung Zangbo siv cov hlau tsis xeb 06Cr13Ni4Mo uas muaj cov pa roj carbon tsawg (txhua chav yuav tsum tau 300-400 tons), nrog rau tag nrho kwv yees li ntawm 28,000-37,000 tons, los tiv taus kev cuam tshuam ntawm dej ceev thiab cavitation erosion. Cov hlau tsis xeb duplex pheej yig siv rau hauv cov pob qij txha txuas ntawm tus choj thiab cov kev txhawb nqa kis tau tus mob kom tiv taus qhov chaw noo noo thiab corrosive ntawm thaj chaw tiaj tiaj, nrog rau qhov loj me ntawm kev lag luam ntawm kaum tawm billions ntawm yuan.

4. Lub Tsev Ruaj Khoov thiab Cov Qauv Kev Lag Luam

Cov phab ntsa ntaub thaiv vaj tse (xws li Shanghai Tower), cov tshuaj reactors (316L rau kev tiv thaiv corrosion siv lead ua), thiab cov cuab yeej phais mob (electrolytically polished304/316L) vam khom cov hlau tsis xeb rau nws txoj kev tiv taus huab cua, kev huv, thiab cov khoom dai kom zoo nkauj. Cov khoom siv ua zaub mov thiab cov ntaub ntawv siv hauv tsev (430/444 hlau) siv nws cov khoom yooj yim ntxuav thiab tiv taus chloride ion corrosion.
