Muaj peev xwm siv tau thiab cov ntaub ntawv siv tau rau cov hlau tubular hluav taws xob cua sov ntsiab lus

1 Scope

Cov txheej txheem no qhia txog ntau yam kev xav tau rau cov hlau tubular hluav taws xob cua sov cov ntsiab lus (tom qab no hu ua cov khoom), suav nrog kev faib khoom, kev xav tau, kev sim, kev tshuaj xyuas, cov qauv, ntim, kev thauj mus los thiab khaws cia, xaj thiab xa khoom.

Cov txheej txheem no siv los sau cov khoom siv hluav taws xob cua sov nrog cov raj hlau ua lub casing.

Cov qauv no tsis siv rau tubular hluav taws xob cua sov cov ntsiab lus rau kev siv txhua hnub thiab cov hom phiaj zoo sib xws.

Rau cov khoom siv hauv lub tshuab nqus tsev lossis cov khoom siv nrog lub siab siab tshaj 1MPa thiab nrog cov kev cai tshwj xeeb, ntxiv rau kev ua raws li tus qauv no, lawv kuj yuav tsum ua raws li cov qauv kev cai tshwj xeeb.

2 Cov ntaub ntawv siv tau zoo

Cov ntaub ntawv hauv qab no yog qhov tseem ceeb rau kev siv daim ntawv no. Rau tag nrho cov ntaub ntawv siv nrog cov hnub, tsuas yog cov version nrog cov hnub siv rau daim ntawv no. Rau tag nrho cov ntaub ntawv hais txog yam tsis muaj hnub, qhov tseeb version (nrog rau txhua daim ntawv hloov kho) yuav tsum siv rau thawj daim ntawv.

Hlau raj hom hluav taws xob cua sov ntsiab

Siv ib lub raj hlau raws li lub plhaub sab nraud thiab cov hlau alloy cua sov ua cov cua sov, muaj cov hlau lead tawm (xov hlau) hauv ib lossis ob lub Rui. Qhov tuab me xob magnesium oxide rwb thaiv tsev nruab nrab yog sau hauv cov raj hlau los kho cov cua sov ntawm lub cua sov.
