Feem ntau kev xaj kev txiav txim siab rau hauv tsev neeg me ntawm cov qib kawm. Dual - cim xws li304/304Llossis316/316LUa kom yooj yim vuam nyob ze ntawm lub taub hau haz thaum khaws cov hom phiaj muaj zog hauv tib kab kab.

Cov lus 1 -} ntau 312 cov qib thiab kev siv tau

* Muaj qhov muaj thiab kev lag luam sib txawv los ntawm thaj av thiab cov zeb txoj kev.

Siv cov nuj nqis no rau kev kuaj ntxov; Qhov kawg yuav tsum tau ua raws li cov lus qhia tshiab ttm / asme

Tab 2 -} Qhov tseeb chemistrial (wt.%)

Cov lus 3 -} Cov chav tsawg kawg - kub tensile

Tsim kev suav muaj nyob ntawmPub cuam tshuam txog kev ntxhov siab vs.Los ntawm cov cai uas siv tau ntau dua li chav -} kub tus lej ib leeg.

Yeeb nkab feem ntau yog ua rawsASME B36.19MCov. Xaiv5S/10S/40S/80SCov sijhawm teem yuav tsum sib npaug siab, kev tso cai ntawm xeb, thiab vuam nkag mus. Rau kev tsim kho kev ua haujlwm, ntau txoj haujlwm xaiv txiav - {lotion pric yuav txo cov teb welds. Kawg Npaj ua ke nrog cov sib koom ua ke: lub tiaj lossis square {{luas} Txiav rau orbital thiab (socketed ua haujlwm, beveled rau pob tw welds. Thaum Orbital Vuam lossis qhov kev kuaj mob tob tob tau npaj siab, nruj OD thiab phab ntsa dograses pab txo kom haum li- Up tawg. Cov kev xaiv deg suav nrog pickled / passivated lossisci - annaled (ba); Cov dej num nrog nruj kev huv siab los yog tsawg reughness ntawm daim id yuav tsum qhia ob qho tib si ua tiav thiab txais kev ntsuas.

Ob txoj kev nyob rau A312 thiab tuaj yeem coj tus cwj pwm sib luag thaum kev kho cua sov thiab nde tau sau tseg kom raug. Welded (EFW / EFW) muaj peev xwm thiab nqi nyiaj hauv NPS thiab ntev khiav yog cov lus qhia tau zoo-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} annealed thiab passivated. Seamless yog feem ntau nyiam qhov twg siab hloov chaw, nruj khoov, lossis cov spools complexs xav tau kev xav tau lub zog txawv. Lub datasheet yuav tsum txhais cov kev twg uas tau lees paub thiab ua pov thawj ua pov thawj rau txoj haujlwm npaj siab.

Tau zoo A312 cov system pib hauv khw tsis yog kev pabcuam. Anustenitic Stainless yeeb yuav tsum tawm ntawm cov kev daws teeb meem {{} txias} txias txias yog redicolided thiab ib tug uniform Austenitic Matrix tau rov qab los. Qhov twg welded yeeb nkab siv, cov nqaws tau coj mus rau tib qho kev daws {{} annealed lub xeev; Ib nrab lossis hauv zos anneals tau poob siab vim tias lawv tawm ntawm microstructures thiab tsis sib xws teb.

Kev ncaj ncees sab yog tswj hwm raws li ib qho xwm txheej: kev siv hluav taws xob, kev tu, passivation, thiab pov thawj. Lub tshav kub zas, kos duab hlau, thiab cov chloride seem yog peb feem ntau cov chiv keeb ntawm kev ua kom huv huv corrosion. Yog tias muaj kev tshem tawm tom qab vuam, tshem nws cov mechanically thiab tom qab ntawd rov qab ua yeeb yaj kiab los ntawm kev ua haujlwm tshwj xeeb (ntau tus tswv cuab kev lag luam kev lag luam xws li ATM A380 / A967). Rau cov kev pab cuam uas xav tau tus lej du lossis qis rougging nyiam, ci - Cov khoom lag luam yuav tau teev ua ke rau daim id tiav thiab huv si.

Weld -}} Txoj kev ua tau zoo ib sab feem ntau yog nyob ntawm cov qauv kev qhuab qhia ntau dua li ntawm kev xaiv. Siv l -}}} qib lossis cov qib ruaj khov nyob ze Welds pab kom tsis txhob muaj lub siab nyiam; high -} Cov khoom ua tau zoo nyob rau ntawm daim id minimizes kub tint thiab oxide nplai; Thiab txhij rau post - weld ntxuav tiv thaiv cov chaw ua pob. Tooling thiab media yuav tsum yog stainless {{6} {{{}} steel txhuam tuaj yeem emle steel tau emined dawb uas tom qab cov xeb thiab undermines lub passive zaj duab xis.

Kev nyiam huv thiab kev ceev kom kaw lub voj. Txhais li cas tus id yog yaug, qhuav, thiab muaj kev tiv thaiv, thiab yuav ua li cas cov kaus mom tas li yog muab pov tseg rau hauv cov ntaub ntawv khaws cia thiab cov zaub mov xa tuaj. A practical evidence set for handover includes heat-treatment charts, passivation records, ID cleanliness results, and if specified, roughness or ferrous-contamination checks. Thaum cov kev tswj hwm no tau sau rau hauv datasheet thiab tua tas li, welded thiab seamless thiab seamless om312 kab coj tau sib npaug hauv lub teb thiab ua kom lawv corrosion tiv taus lub sij hawm ntev.

Es tsis yog ib daim ntawv txheeb ntawm cov mos txwv, xav tias yog cov pov thawj. Ib qho khoom ua qauv qhia kev ncaj ncees (hydrostatic lossis tsis muaj hluav taws xob hluav taws xob ib ib.312). Lwm tus paub meej tias phab ntsa thiab daim ID txuas ntxiv (Eddy - tam sim no los yog siv 100% ntev rau cov tshuab. Qhov twg rhiab yog qhov pheej hmoo, ib txoj kev txhim kho corrosion (ttm A262) ntxiv. PMI paub tseeb tias Alloy tus kheej ntawm cov bundles. Cov ntaub ntawv teeb tsa muab MTC traceability los ntawm tshav kub los pob, nrog kev lees paub thiab tshaj tawm cov hom ntawv pom zoo hauv ITP. Thaum tus tswv yuav tsum tau, thib peb {-} kev pom zoo (piv txwv li,Bv, Sgs) tuaj yeem npaj tau.
