API X80 ERW Yeeb Nkab

API 5L X80 kuj welded yeeb nkab yog ib qho kev xaiv nyob rau hauv American Petroleum Institute's "API Spec 5L Line Pipe Specification." Hauv API Spec 5L tus qauv, 'X' sawv cev rau cov raj xa dej, thiab '80' qhia txog qib zog, ntsuas hauv kpsi. X80 qhia txog cov yeeb nkab steel nrog qhov tsawg kawg nkaus lub zog ntawm 80 kpsi, uas yog kwv yees li 552 MPa hauv metric units. API 5L X80 welded kav feem ntau yog muab nyob rau hauv qhov kub-dov los yog normalized mob.

Yuav ua li cas tiv thaiv cov kab nrib pleb hauv API 5L X70 welded kav

Kev tiv thaiv feem ntau yog tshem tawm kev ntxhov siab thiab raug siv cov khoom siv vuam, nrog rau kev txhim kho cov txheej txheem ua haujlwm. Ua tib zoo saib rau daim ntawv ntawm qhov sib koom ua ke kom tshem tawm cov kab nrib pleb uas tshwm sim los ntawm qhov tsis sib xws ntawm cov cua sov thiab cua txias vim thermal stress. Thaum welding txawv thicknesses ntawm steel daim hlau, thinning yuav tsum tau nqa tawm rau tuab steel daim hlau. Kev xaiv cov ntaub ntawv yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov qauv tsim, thiab qhov chaw ntawm hydrogen yuav tsum tau tswj nruj me ntsis. Vuam rods yuav tsum tau qhuav ua ntej siv, thiab cov roj thiab noo noo impurities nyob rau hauv lub zawj yuav tsum tau ua tib zoo ntxuav. Thaum lub sij hawm vuam, xaiv qhov tsim nyog vuam tsis txwv los tswj cov khoom siv hluav taws xob hauv qhov txias txias ntawm 800 ~ 3000 degree txhawm rau txhim kho microstructure ntawm vuam thiab thaj chaw muaj kev kub ntxhov. Nyob rau hauv ib puag ncig nrog qis vuam kub thiab cov ntaub ntawv thinner, ntxiv rau kev ua haujlwm ntawm qhov kub thiab txias, preheating yuav tsum tau nqa tawm ua ntej vuam. Tom qab vuam, kev siv zog yuav tsum tau ua kom muaj rwb thaiv tsev thiab ua kom txias, thiab kev kho cua sov tom qab vuam yuav tsum tau ua kom tshem tawm cov kab nrib pleb uas tshwm sim los ntawm kev ntxhov siab nyob hauv qhov vuam thaum lub sij hawm txias.
