Cov xwm txheej tam sim no
Raws li Susan, Tus Thawj Saib Xyuas Kev Ua Haujlwm ntawm Lork Group, Kuv tau sau thiab tshuaj xyuas cov ntawv sib tham thiab hu xov tooj kaw ntawm cov neeg siv khoom nug txog duplex stainless hlau nyob rau lub hlis dhau los.
Kuv nrhiav tau ib tus qauv txawv: 70% ntawm cov lus nug no tsis tau nug, "Pib steel ntau npaum li cas ib tuj?" Hloov chaw, lawv tau nug -
"Vim kuv qhov kev ua haujlwm tshwj xeeb, kuv puas yuav tsum siv Qib 2205 lossis qib kev lag luam?"
"Kuv tsis muaj peev xwm txiav qhov no kuv tus kheej; koj puas tuaj yeem txiav nws kom loj rau kuv?"
"Kuv ntiav ib tus neeg los vuam lub sijhawm kawg no, tab sis nws pib tawm sai sai tom qab ntawd; koj puas tuaj yeem tuav lub vuam?"
"Peb muaj kev kos duab rau kev cai duplex steel Cheebtsam; koj puas tuaj yeem tsim lawv?"
Cov lus nug hauv qab no yog qhov muaj tseeb tiag: qhov uas cov neeg siv khoom xav tau tiag tiag tsis yog cov phaj hlau xwb, tab sis yog qhov npaj tau - rau - siv cov khoom siv - nrog rau tus khub kev ntseeg siab uas muaj peev xwm muab kev txhawb nqa thiab kev lees paub.
Qhov no yog vim li cas Lork Group tso nws tus kheej ua "Duplex Steel Solutions Library." Peb tsis yog muag khoom xwb; es, peb tau distilled ib tug txheej txheem txheej txheem ntawm kev xaiv logic thiab ua cov qauv raws li ib tug ntau yam ntawm kev khiav hauj lwm tej yam kev mob.
Duplex Steel Xaiv thiab Machined Cheebtsam
Hauv qab no, hais txog plaub qhov xwm txheej uas cuam tshuam nrog kev thov ntawm duplex stainless hlau, peb yuav muab cov kauj ruam -los ntawm - kauj ruam teb rau txhua tus.
Scenario 1: Petrochemicals - Qhov nruab nrab Corrosion hnyav
Client's Original Words:"Lub nkoj ntauwd muaj H₂S thiab chloride ions. Peb yav tas los siv 316L, tab sis nws tsim pitting corrosion nyob rau hauv tsawg tshaj li ib xyoos. Tam sim no peb xav sim siv duplex stainless hlau; koj puas muaj lus pom zoo?

Hauv qab - kab hauv paus ntsiab lus: Hauv thaj chaw petrochemical, tsis txhob skimp ntawm cov nqi. Economical duplex steels tsuas yog tsis txaus ntawm no; yog tias lawv ua tsis tiav, qhov tshwm sim los ntawm kev poob qis yuav yog ib puas npaug ntawm tus nqi ntawm cov khoom lawv tus kheej.
Fabricated Components: Cov lus pom zoo
Lork Group muab cov khoom ua ntej-fab ntauwd sab hauv, flanges, thiab cov ntawv raj. Peb lav cov khoom muaj tseeb thiab muab cov ntaub ntawv qhia txog ferrite cov ntsiab lus (tshaj tawm ntawm 40% -60%).
Lus Cim: Rau tag nrho cov khoom siv welded, peb nruj me ntsis ua raws li cov txheej txheem ntawm cov khoom siv hluav taws xob tsawg dua lossis sib npaug li 15 kJ / cm3 thiab qhov kub sib txawv tsawg dua lossis sib npaug li 150 degree. Tsis tas li ntawd, peb ua dye penetrant kuaj ua ntej xa zaub mov.
Scenario 2: Chemical Tanker - Tag Nrho Liquid Contact
Client's verbatim comment:"Kev cais pawg neeg muaj ntawv pov thawj yuav tsum tau; yog tias lub phaj dav tsis txaus, nws ua rau muaj ntau tus welds-ib yam dab tsi tus tswv nkoj yuav tsis pom zoo."

Lork Group tuav cov khoom npaj npaj dav ntawm - cov ntawv phaj thiab muab cov kev pabcuam txiav kev cai - rau qhov ntev thiab qhov dav - yog li txo qhov ntim ntawm splicing thiab vuam ua haujlwm yuav tsum tau ua ntawm lub nkoj nkoj.
Peb tseem tuaj yeem ua cov khoom siv ua ntej ua vaj huam sib luag raws li engineering kos duab; Cov vaj huam sib luag no tuaj yeem ua tiav nrog beveling, tus lej cim, thiab nrog cov txheej txheem Vuam Kev Tsim Nyog (PQR).
Cov neeg siv khoom tawm tswv yim: "Yav dhau los, ib lub nkoj yuav tsum tau 300 meters ntawm duplex stainless hlau vuam seams. Los ntawm kev siv koj daim hlau dav, peb tuaj yeem txo tag nrho cov vuam ntev mus rau 180 meters.
Scenario 3: Coastal Structures · Choj Railings
Tus neeg siv khoom cov lus tseeb:"Peb yuav tsum tau nruab cov guardrails raws ntug dej hiav txwv. Peb muaj kev txhawj xeeb txog chloride corrosion yog tias peb siv 304 stainless hlau, tab sis peb pom 2205 yuav kim heev. Puas muaj qhov nruab nrab - hauv av xaiv?"
