EN 10217-1 P195TR2 Hlau Welded Yeeb Nkab
EN 10217-1P195TR2 steel yeeb nkab qib yog welded steel hlab rau siab lub hom phiaj nyob rau hauv cov kev pab cuam lub sij hawm teev nyob rau hauv lub European Standard.Cov txheej txheem European no siv rau cov welded ncig cov raj ua los ntawm cov hlau tsis muaj hlau thiab cov hlau tsis muaj hlau nrog cov khoom kub siab, Lub npe ntawm cov yeeb nkab no hais txog nws qhov tsawg kawg nkaus yield zog hauv MPa kev ntxhov siab thaum lub sij hawm tsim khoom. Cov welded steel yeeb nkab no muaj qhov zoo weldability thiab tsim nyog rau cov txheej txheem vuam sib txawv, xws li fusion vuam thiab tsis kam vuam. Cov pa roj carbon steel yeeb nkab no feem ntau yog siv rau hauv boilers, tshav kub exchangers, thiab lwm yam khoom siv kub thiab kav dej. Raws li cov txheej txheem kev cai ntawm cov qauv sib txawv, nws kuj tuaj yeem siv rau hauv nkoj, tsheb, txuas hniav, kev tsim kho, thiab lwm yam. Ntxiv rau nws cov khoom muaj zog, cov yeeb nkab carbon steel zoo li no kuj muaj cov yam ntxwv ntawm nws qhov zoo heev toughness, ductility, thiab hnav tsis kam. Cov yam ntxwv zoo heev no ua rau EN10217-1 P195TR2 yog cov khoom siv zoo tshaj plaws rau ntau daim ntawv thov kev lag luam.
EN10217 P195TR2 Vuam Hlau Lub Npe Tsim
P195TR2 tsab ntawv loj P rau lub hom phiaj siab;
P195TR2 yog qhov qhia tau hais tias qhov tsawg kawg nkaus yield zog rau thickness tsawg dua los yog sib npaug rau 16 hli;
Lub alphanumeric TR2 rau kev ua tau zoo nrog cov ntsiab lus ntawm txhuas, cov khoom cuam tshuam, thiab kev tshuaj xyuas tshwj xeeb thiab kev sim.
Qhov tshwm sim ntawm EN 10217-1 P195TR2 Pipes
- Weld Seam
EN 10217-1 cov yeeb nkab yog tsim los ntawm cov khoom sib txawv, txhua qhov muaj qhov sib txawv ntawm qhov yuav tsum tau vuam. Feem ntau yog ferritic thiab austenitic steels, uas yuav tsum tau welded nrog kev saib xyuas kom tsis txhob tawg, tsis muaj fusion, thiab tsis muaj kev nkag mus. Kev kho rau lub vuam seam ntawm EW thiab HFW raj tsis raug tso cai. Kev kho rau qhov vuam seam ntawm SAW raj tuaj yeem raug tso cai yog ua tiav los ntawm cov txheej txheem sau tseg.
- Tube Nto
EN 10217-1 yeeb nkab yuav tsum muaj qhov chaw uas tsis muaj qhov tsis xws luag uas tuaj yeem pom ntawm qhov muag liab qab. Yog tias muaj qhov tsis zoo ntawm qhov chaw uas yuav tsum tau hnav khaub ncaws, lawv yuav tsum txwv rau kev sib tsoo lossis machining. Phab ntsa thickness nyob rau hauv qhov hnav khaub ncaws yuav tsum tsis txhob tsawg tshaj li qhov tsawg kawg nkaus phab ntsa thickness. Txhua qhov chaw hnav khaub ncaws yuav tsum sib xyaw ua ke rau hauv qhov contour ntawm lub raj. Txhua qhov chaw tsis zoo uas tob dua 5% ntawm phab ntsa tuab T lossis 3 hli, qhov twg me dua, yuav tsum tau hnav.

Kos npe yuav siv rau EN 10217-1 P195TR1 Pipes
Txhawm rau kom muaj kev nyab xeeb ntawm cov welded steel raj, nws yog ib qho tseem ceeb uas txhua lub raj yuav tsum kom meej meej thiab indelibly cim nrog cov ntaub ntawv tseem ceeb ntawm cov chaw tsim khoom, hom raj, qauv, thiab qib steel npe. Kev kos npe no tuaj yeem ua tiav los ntawm ntau txoj kev xws li kev sib txuas tsis siv neeg lossis cov txheej txheem pleev xim, xim stencil lossis nyuaj stamping (siv tsis tshua muaj kev ntxhov siab lossis tus pin stamps), lossis ua ke ntawm cov no. Rau cov raj uas muaj sab nraud txoj kab uas hla ntawm ntau tshaj 51 hli, cov cim yuav raug hloov los ntawm daim ntawv lo los yog daim ntawv cim ruaj ntseg txuas nrog lub nras lossis lub thawv, uas yuav tsum tau txheeb xyuas lub raj txoj kab uas hla, phab ntsa tuab, thiab qhov ntev ntev. Los ntawm kev ua kom pom tseeb thiab ruaj khov rau txhua lub raj hauv qhov no, peb tuaj yeem pab ua kom muaj kev nyab xeeb ntawm welded steel raj.
