API 5L Welded Steel Yeeb Nkab

Cov kab yeeb nkab steel feem ntau yog carbon steel thiab ua raws li API SPEC 5L specifications. Siv rau kev lag luam roj av thiab roj av, roj kev lag luam yuav tsum tau ua rau kev thauj mus los thiab yuav tsum ua haujlwm nyob rau hauv qhov xwm txheej hnyav, qhov kub thiab txias, corrosion kuj rau corrosive ib puag ncig, thiab rau cov kev pabcuam qaub hauv H2S.

Common Class: API 5L Gr.B PSL1, PSL2, Sour Service yeeb nkab
Qhov nruab nrab: X42, X46
Loj: X52
Nruab nrab thiab siab: X56
Qib siab: API 5L X60 PSL1, PSL2 LSAW kab yeeb nkab
Siab: API 5L X65 PSL1, PSL2 LSAW / SSAW kab yeeb nkab
Hwm siab: API 5L X70
Hwm siab: API 5L X80

PSL2 yeeb nkab los nrog tsab ntawv N, Q, M, xws li API 5L X52N, API 5L X60Q / M.
Sour cov yeeb nkab nrog cov ntawv txuas ntxiv NS, QS, MS, xws li API 5L X65QS.

Muaj 3 hom vuam: ERW (Electric Resistance Vuam), LSAW (Longitudinally Submerged Arc Vuam), thiab SSAW (Spirally Submerged Arc Vuam) hom vuam.

ERW yeeb nkab yog hom Resistance yeeb nkab sawv sib nrug ntawm cov yeeb nkab welded thiab DC welded yeeb nkab nyob rau hauv ob yam sib txawv raws li teev hauv qab no. Raws li cov vuam zaus, IF vuam rau tsawg zaus thiab ultra-IF welding rau siab zaus. Nyob rau hauv cov ntaub ntawv ntawm nyias-walled yeeb nkab, muaj ib tug high zaus weld siv feem ntau nyob rau hauv cov ntaub ntawv ntawm kev sib cuag welding thiab induction welding. Thaum siv rau cov yeeb nkab me me, lawv siv DC vuam. Muaj cov txheej txheem vuam ntau zaus siv los tsim cov kav dej uas muaj dav thiab yog hom ERW. Rau cov roj thiab roj cia, hom kev pom zoo tshaj plaws yog ERW longitudinal, vim nws qhov zoo, yooj yim ntawm kev thauj thiab nqi.

Ob leeg LSAW yeeb nkab thiab SSAW yeeb nkab yog SAW yeeb nkab (Submerged Arc Welding Steel Pipe), yog tsim los ntawm kev siv cov txheej txheem submerged arc soldering rau kev npaj cov hlau thiab nws ua rau cov yeeb nkab siab. Raws li cov txheej txheem flux, tsis muaj qhov poob tam sim ntawd thiab nws tau concentrated nyob ze ntawm qhov vuam. Nws ua rau muaj kev ua tau zoo, muaj txiaj ntsig zoo arc thiab cov pa luam yeeb, uas pom kev siv ntau hauv cov hlab ntsha siab, cov kav dej tsim, kab teeb, kua dej, steel ua haujlwm thiab lwm yam.
