Cov ncauj lus kom ntxaws piav qhia ntawm kev tsim khoom lag luam thiab cov khoom siv rau cov khoom lag luam hlau
Tee, ib lub sij hawm uas suab heev tshaj lij, ua tau ntau lub npe hauv kev lag luam. Piv txwv li, sib npaug cov kab uas hla kev, cov khoom lag luam tsis zoo, cov tshuaj pleev pob txha, ua kom zoo nkauj Kev tso tawm cov khoom tawm thiab kev tawm hauv qab ntoo, loj} Txoj kab ntawm lub ntsej muag, thiab ntau yam kev sib txuas ntawm peb lub hom phiaj, tab sis kuj tseem qhia txog kev sib txuas ntawm nws cov ntaub ntawv.
Cov khoom siv ntawm Tee tuaj yeem yog Q235b, Q355B, Q355C, 2060, L245M, Alloy Pipeline Hlau, L260, L245M, L245m, L245M, L245M, L245M, L245M, L245M, L245M, L245M, L245M, L245M, L260, L245M, L245m, L260, L245M, L245M, L260, L245M, L260, Alloy Pipe Cov Khoom Siv No Piv txwv li, cov roj carbon tev tees tau siv dav hauv ntau daim teb kev lag luam vim lawv lub zog zoo thiab corrosion tsis kam.
Qhov sib piv ntawm phab ntsa tuab rau tus ntoo khaub lig- ntu ntu ntawm Tee yog qhov tseem ceeb hauv kev tsim khoom. Tus me dua cov piv, qhov zoo dua kev ua tau zoo ntawm tee thiab pwm, tab sis sab hauv arc yog qhov tsis muaj peev xwm thiab wrink. Cov kev xam cov lus rau kev thawb sab nraud ntawm lub billet tuaj yeem pab txhawb cov engineers kom tswj tau cov txheej txheem no. Yog hais tias qhov tseeb txheej ntawm cov raj xaiv raj yog me dua li cov qauv dP, tab sis lub arc zoo tshaj plaws nrog cov tee yog qhov tsis muaj peev xwm thiab tawv; Ntawm qhov tsis sib xws, yog tias cov taub uas muaj lub cheeb ntawm cov nqi xaiv loj dua li cov nqi DP suav raws li cov qauv, qhov tshwm sim yuav yog qhov fab ntxeev.
Thaum lub sij hawm tsim kev tsim khoom, qhov ntsuas kub qeeb yog qhov chaw tswj tseem ceeb. Thaum thawb, tus thawj coj compressive siab rau sab hauv ntawm Tee yuav tsum tsawg dua li cov txiaj ntsig txwv ntawm cov khoom ntawm qhov kub no. Qhov ntsuas kub ntsuas feem ntau txuas ntxiv sib txuas ua ke deb- kev kub ntxhov- incise tswj ntawm kub faib.
