316 stainless hlau duab plaub tubing yog tsim los siv cov txheej txheem sib txuas automated vuam nrog cov duab txias lossis txias dov, ua kom nruj qhov ntev precision nrog tus ntoo khaub lig -sectional kam rau ua ntawm ± 0.5 hli thiab phab ntsa thickness kam rau ua ntawm ± 0.05 hli.
316 stainless hlau khaws cia zoo heev lub zog thiab toughness nyob rau hauv siab - qhov kub thiab txias ib puag ncig, tswj oxidation tsis kam ntawm qhov kev pab cuam tas li kub txog li 870 degree. Yog li ntawd nws yog qhov zoo - haum rau siab - daim ntawv thov kub, xws li cov tshuab tso pa tawm thiab cov kav dej hauv boiler hauv cov fais fab nroj tsuag.
Customized Services
- TORICH muaj precision txiav rau ib qho ntev ntev, nrog rau qhov ntev ntawm ± 1 hli thiab qhov kawg - lub ntsej muag perpendicularity tsawg dua los yog sib npaug rau 0.5 degree, yog li ua tau raws li qhov yuav tsum tau ua rau kev sib dhos precision.
- Peb muab ntau yam kev kho deg, nrog rau cov tshuab polishing, acid pickling thiab passivation, thiab ci annealing.
- Peb kuj tseem muab cov txiaj ntsig - ntxiv cov kev pabcuam ua haujlwm- xws li drilling, qhov milling, kawg chamfering, flange vuam, thiab raj dabtsi yog khoov- ua kom tiav tiav raws li cov neeg siv khoom kos duab thiab cov lus qhia tshwj xeeb.

Cov qhab nia xaiv tau
- 304 / 304L- Siv dav, ntau yam, thiab tus nqi - zoo rau kev tiv thaiv corrosion.
- 310 Stainless hlau- Zoo heev rau kev ua haujlwm siab - kub.
- 316L Stainless hlau- Tsawg- qib carbon nrog txhim kho weldability thiab tsis kam mus rau rhiab heev.
- Duplex Stainless hlau- Rau siab zog thiab chloride kev nyuaj siab corrosion kuj.
thaj chaw siv
ASTM A554 Qib 316 stainless hlau plaub lub raj yog tsim rau siv nyob rau hauv cov qauv thiab cov koom haum pab nyob rau hauv lub zog tsim ib puag ncig, xws li:
- Fais fab nroj tsuag structural systems: Generator enclosure thav ntawv, khoom mounting lug, thiab lwm yam.
- Thaum tshav kub kub hloov thiab thermal systems: Thaum tshav kub kub exchanger txhawb thav ntawv, condenser structural Cheebtsam, thiab lwm yam.
- Lub tshuab hluav taws xob hluav taws xob thiab emission tswj cov tshuab: chimney thiab duct kev txhawb nqa cov qauv, cov khoom siv hluav taws xob tso pa tawm, thiab lwm yam.
- Cov cua txias thiab cov dej ntws: Cov cua txias ntauwd kev txhawb nqa, cov txheej txheem dej.
- Kev tsim hluav taws xob txuas ntxiv dua tshiab: Cov khoom siv rau lub hnub ci thermal fais fab nroj tsuag.
- Offshore thiab ntug hiav txwv fais fab chaw nres tsheb: Cov khoom siv hluav taws xob, offshore platform fais fab module thav ntawv, thiab lwm yam.

Q: Nws puas ua tau raws li qhov yuav tsum tau ua rau cov chaw tsim hluav taws xob?
A: Nws yog tag nrho ua raws. Cov tubing yog tsim nyob rau hauv nruj raws li tus qauv ASTM A554, thiab daim ntawv pov thawj Material Test (MTC) thiab Non-Kev Ntsuas Kev Ntsuas (NDT) tau muab rau txhua pawg. Nws kuj ua tau raws li qhov yuav tsum tau ua rau ISO 9001 qhov system ntawv pov thawj thiab EU CE daim ntawv pov thawj.
Q: Yuav ua li cas yog nws weldability? Nws puas tuaj yeem ua tau raws li qhov xav tau ntawm vuam cov khoom siv hluav taws xob?
A: Tom qab vuam, cov tubing tau txais kev kho annealing; Yog li ntawd, lub zog ntawm vuam seam sib tw ntawm cov khoom siv hauv paus, tso cai rau kev sib txuas ncaj qha thiab kev teeb tsa.
Q: ASTM A554 lub raj raj puas tuaj yeem siv rau hauv cov kav dej siab?
A: Tsis yog, nws ua tsis tau. ASTM A554 yog tus qauv rau kev siv tshuab raj, tsim los rau cov qauv tsim, kho kom zoo nkauj, thiab qis - cov ntawv siv tshuab siab- tsis yog rau siab - cov kua xa tawm. Rau cov kav dej siab, cov qauv xws li ASTM A312 lossis ASTM A358 yuav tsum raug xaiv.
