Cov qhab nia xaiv tau
- 316L muaj tus nqi qis thiab kev ua haujlwm zoo, ua rau nws tsim nyog rau kev tswj hwm hydraulic hauv qis - siab, qis - chloride, thiab tsis yog - acidic ib puag ncig; Txawm li cas los xij, nws tsis pom zoo rau kev tswj hwm hydraulic tseem ceeb hauv kev siv roj thiab roj offshore.
- Nickel-raws li cov alloys xws li Inconel 625 ua tau zoo tshwj xeeb hauv ib puag ncig uas muaj qhov kub thiab txias, siab acidity, thiab cov tshuaj chloride siab, tab sis lawv yog ob peb zaug kim dua S32750 thiab nyuaj rau fabricate.
- Rau hydraulic tswj systems ua hauj lwm nyob rau hauv lub sij hawm ntev nyob rau hauv acidic ib puag ncig nrog chloride concentrations, kub tsis tshaj li ntawm 150 degree, thiab tsis siab H₂S ib nrab siab, S32205 / S31803 duplex stainless hlau yog ib tug haum xaiv.

FAQ
Q: Qhov kev pabcuam siab tshaj plaws rau S32750 seamless yeeb nkab yog dab tsi?
A: Rau cov kev pabcuam corrosive, qhov kev pom zoo ua haujlwm tsis tu ncua yog qis dua 315℃(600℃F). Ntev ntev ntawm duplex stainless hlau mus rau qhov kub ntawm 300℃thiab 500℃ua rau "475℃embrittlement" (teev nag los ntawm 'theem), thaum raug rau 600-900℃ua rau sigma (σ) theem nag lossis daus, ua rau txo qis hauv toughness thiab corrosion kuj.
Q: S32750 puas tuaj yeem welded? Cov txheej txheem twg yog siv rau ntawm -site hydraulic kab txuas?
A: S32750 muaj qhov zoo weldability, tab sis nws yuav tsum muaj kev sib txuam super duplex vuam consumables (xws li ER2594 hlau los yog E2594 electrodes) thiab tswj cov cua sov inputs; post-weld tov annealing yog pom zoo. Rau me me - txoj kab uas hla hydraulic tswj kab, ntawm - qhov chaw sib txuas feem ntau siv compression fittings lossis flanges.
Q: Puas yog kev cai txiav ntev thiab xaus -fab machining muaj?
A: Yog. Peb muab cov kev pabcuam ua haujlwm- suav nrog kev ruaj khov-ntev txiav, tiaj- xaus kev ua tiav, beveling, deburring, thiab kawg- ntsej muag polishing- raws li koj cov duab kos kom tau raws li qhov yuav tsum tau ua rau kev teeb tsa rau compression fittings thiab instrumentation tubing.
