304 Cov yeeb nkab ua kua txias

304 stainless hlau muab qhov zoo tshaj plaws tus nqi-rau-kev ua tau zoo piv rau cov kua txias siv cov dej ntshiab, DI dej, los yog glycol-based coolants nrog cov ntsiab lus chloride tsawg (feem ntau <200 mg/L Cl⁻). 316 stainless hlau muaj 2-3 % molybdenum, uas muab superior tiv thaiv rau pitting thiab crevice corrosion nyob rau hauv dej hiav txwv (eg, dej hiav txwv). Yog tias koj lub tshuab ua kom txias siv cov dej ntshiab huv lossis glycol sib xyaw rau hauv ib puag ncig hauv tsev tswj (cov ntaub ntawv chaw, lub thawv roj teeb), 304 yog qhov txaus thiab pheej yig dua. Tuam Tshoj super tech muaj ob qho tib si 304 thiab 316 kev xaiv, thiab peb pab koj xaiv cov qib zoo raws li koj qhov kev ua haujlwm tiag tiag - tsis muab muag rau koj rau cov khoom kim dua uas koj tsis xav tau.

Qhov sib txawv tseem ceeb yog cov ntsiab lus carbon: tus qauv 304 muaj C tsawg dua lossis sib npaug li 0.08%, thaum 304L muaj C tsawg dua lossis sib npaug li 0.035%. Cov pa roj carbon qis qis tiv thaiv kev hnov ​​​​mob - qhov tsim ntawm chromium carbides ntawm cov ciam teb thaum lub sij hawm vuam, uas depletes chromium ze ntawm vuam thiab tuaj yeem ua rau intergranular corrosion. Tuam Tshoj super tech khoom siv dual-certified 304/304L cov ntaub ntawv, lub ntsiab lus cov ntsiab lus carbon raws li 304L txwv thaum cov khoom siv ua tau raws li lossis tshaj 304 qhov yuav tsum tau ua. Koj tau txais qhov weldability ntawm 304L thiab lub zog ntawm 304 hauv ib yam khoom - qhov no yog peb tus qauv, tsis yog kev hloov kho.

Yog lawm. Tuam Tshoj super thev naus laus zis tau ua 1,000-teev kev sim txuas ntxiv rau hauv 50% ethylene glycol / 50% DI dej ntawm 80 degree, ua kom pom qhov poob qis thiab tsis muaj pitting corrosion. Qhov kev ntsuam xyuas no yog qhov xav tau ntau dua li cov kev kuaj ASTM A262 intergranular corrosion, uas tsuas yog ntsuas cov khoom raws li kev xa khoom. Peb qhov kev sim simulates xyoo ntawm kev pabcuam hauv kev nrawm. Tsis tas li ntawd, cov ntsiab lus tsis tshua muaj carbon tsawg ntawm peb cov ntawv pov thawj dual 304/304L kom ntseeg tau tias cov pob qij txha welded hauv glycol Circuit Court yuav tsis raug kev cuam tshuam intergranular - hom tsis ua haujlwm feem ntau hauv cov qauv 304 kav dej tom qab vuam.

Tuam Tshoj super tech thiab peb 304 cov kav dej txias tau ntawv pov thawj hauv qab no:

ISO 9001:2015 - Kev Tswj Xyuas Zoo

ISO 14001: 2015 - Environmental Management System

ISO 45001:2018 - Kev Ua Haujlwm Kev Noj Qab Haus Huv & Kev Nyab Xeeb

ISO 3834 - Vuam Qhov Yuav Tsum Tau Zoo (tseem ceeb rau cov yeeb nkab sib txuas nrog cov welded txuas)

CE Marking - Ua raws li EU cov lus qhia

RoHS - Kev txwv tsis pub muaj tshuaj lom

EU Food-Grade Certification - Paub meej tias tsim nyog rau kev sib cuag nrog cov dej haus thiab khoom noj khoom haus

Cov ntawv pov thawj no tau tshawb xyuas thiab tam sim no, thiab peb muab cov ntawv pov thawj nrog txhua qhov khoom xa tuaj. Cov ntaub ntawv pov thawj zoo no yog qhov sib txawv tseem ceeb - ntau tus neeg xa khoom cov yeeb nkab tuav tsuas yog ISO 9001, thiab qee qhov tsis tuaj yeem muab cov ntaub ntawv taug qab.

Peb cov txheej txheem npog npog OD Ø6-Ø50 hli nrog phab ntsa tuab 0.5-3.0 hli, ncaj ntev txog 6 m thiab coiled daim ntawv (rau OD Tsawg dua lossis sib npaug li 12 hli) txog 18 m. Kev cai qhov ntau thiab tsawg sab nraud qhov no tuaj yeem tsim tau - peb lub peev xwm ua kom tuag hauv tsev tso cai rau peb los tsim cov kab uas tsis yog tus qauv ntawm Ø4 hli mus rau Ø60 hli nrog cov cuab yeej siv sij hawm luv luv li 7 hnub. Hu rau peb pab neeg ua haujlwm engineering nrog koj cov kev xav tau tshwj xeeb rau kev ntsuas qhov ua tau sai thiab hais lus.

Qhov no yog ib lo lus nug tseem ceeb uas ntau tus saib. Tuam Tshoj super tech 304 kua txias kav dej undergo:

Bright annealing nyob rau hauv hydrogen huab cua - ua kom huv si, tsis muaj oxide-dawb sab hauv qhov chaw yam tsis tas yuav tsum tau siv tshuab polishing (uas tuaj yeem kos cov kab mob)

Acid pickling thiab passivation - tshem tawm cov seem seem oxides thiab txhim kho cov chromium oxide passive txheej

Cleanroom ntim - cov kav dej yog purged nrog nitrogen, capped nrog huv huv lub kaus mom, thiab ntim rau hauv lub hnab ntim rau hauv ib qho chaw tswj

Kev xaiv electropolishing - rau ultra-high-purity daim ntaub ntawv, ntxiv txo qhov roughness ntawm Ra tsawg dua los yog sib npaug rau 0.2 μm thiab txhim kho corrosion kuj.

Vim li cas qhov no tseem ceeb: Hauv cov tshuab ua kua txias, txawm tias micron-scale hais tuaj yeem txhaws micro-channel txias daim hlau lossis ua raws li qhov chaw nucleation rau corrosion. Peb cov txheej txheem ua kom huv si, tsis muaj kab mob tsis muaj cov yeeb nkab sab hauv los ntawm lub Hoobkas - koj tsis tas yuav siv sijhawm ntau teev ua ntej ua haujlwm.

Rau qhov ntau thiab tsawg tus qauv, peb cov MOQ yog 500 kg rau ib qho kev txiav txim (kwv yees li 200-500 m nyob ntawm qhov loj). Rau qhov ntau thiab tsawg los yog cov kev cai tshwj xeeb, MOQ yuav txawv - tab sis peb hloov tau thiab tau txais kev txhawb nqa cov qauv kom tsawg li 50 m rau R & D tej yaam num. Peb nkag siab tias kev txhim kho ua kua ua kua txias feem ntau yuav tsum tau kuaj rov qab, thiab peb txhawb koj los ntawm cov qauv los ntawm kev tsim khoom loj. Qhov kev hloov pauv no los ntawm peb qhov kev sib xyaw ua ke vertically - peb tswj tag nrho cov txheej txheem los ntawm cov hlau yaj mus rau cov raj tiav, yog li peb tuaj yeem kho sai sai.

Yog lawm, Tuam Tshoj super tech muab cov yeeb nkab ua tiav - qhov no yog ib qho ntawm peb qhov kev sib tw tseem ceeb. Peb tuaj yeem muab:

Cov yeeb nkab nrog orbital-welded fittings (xws li, Swagelok-hom compression fittings, VCR fittings, flanges)

Khoov thiab tsim cov yeeb nkab spools nrog nruj radii

Ua kom tiav manifold sib dhos nrog ntau ceg txuas

Tag nrho cov kev sib dhos yog 100% kev ntsuas siab thiab helium leak kuaj rau 1 × 10⁻⁹ mbar·L / s thaum xav tau

Feem ntau stainless hlau yeeb nkab cov neeg muag khoom muag tsuas yog cov raj raw. Los ntawm kev muab cov khoom tiav, kuaj cov rooj sib tham, Tuam Tshoj super thev naus laus zis txo koj cov khoom siv sib txuas, kev sib dhos ua haujlwm, thiab kev pheej hmoo zoo. Peb daim ntawv pov thawj ISO 3834 vuam ua kom ntseeg tau tias txhua qhov sib koom ua ke ua tau raws li cov qauv thoob ntiaj teb siab tshaj plaws.
