Qhov txawv ntawm SSAW Yeeb Nkab Thiab LSAW Yeeb Nkab

Qhov txawv ntawm SSAW Yeeb Nkab thiab LSAW Yeeb Nkab

Ncaj seam submerged arc vuam (LSAW) yog tsim los ntawm nias (dov) ib qho nruab nrab-tuab phaj nyob rau hauv pwm los yog ua tshuab thiab siv ob-sided submerged arc vuam thiab txoj kab uas hla expansion. Cov khoom tiav tiav tiav, muaj qhov zoo toughness, plasticity, weld uniformity thiab ntom, thiab muaj qhov zoo ntawm cov yeeb nkab txoj kab uas hla, tuab yeeb nkab phab ntsa, kev kub siab ua hauj, tsis kub tsis kam, thiab muaj zog corrosion kuj. Nws yog dav siv nyob rau hauv kev tsim kho cov roj thiab cov kav dej ntev ntev vim nws lub zog siab, siab toughness thiab zoo. Raws li API cov qauv, hauv cov kav dej loj thiab cov pa roj, cov kav dej ncaj nraim submerged arc steel yeeb nkab yog tib hom yeeb nkab uas tau teev tseg thaum dhau los ntawm Chav Kawm I thiab Chav Kawm II xws li thaj tsam alpine, hiav txwv hauv qab, thiab cov neeg nyob hauv nroog loj.

SSAW steel yeeb nkab (kauv seam submerged arc welded steel yeeb nkab) yog cov yeeb nkab steel uas tau dov kom nws cov kev taw qhia pem hauv ntej tsim lub kaum sab xis nrog cov kab nruab nrab ntawm cov yeeb nkab steel, thiab yog welded thaum sib sau. Lub weld yog nyob rau hauv ib tug kauv zoo. Qhov zoo dua yog tias cov kav hlau steel ntawm ntau txoj kab uas hla tuaj yeem tsim nrog tib qhov tshwj xeeb. Qhov kom zoo dua yog tias cov ntaub ntawv raw muaj zog yoog raws, cov welds tuaj yeem zam qhov kev ntxhov siab loj, thiab kev ntxhov siab zoo dua. Qhov tsis zoo yog tias qhov ntev geometric tsis zoo, qhov ntev vuam ntev ntev dua li cov kav hlau ncaj nraim, thiab vuam tsis xws li cov kab nrib pleb, qhov pores, slag suav nrog, thiab vuam sib txawv yog qhov tshwm sim, thiab qhov kev ntxhov siab ntawm vuam yog nyob rau hauv ib qho kev sib tsoo. tensile stress state. Feem ntau hais lus, cov qauv tsim tshwj xeeb rau cov kav dej ntev ntev thiab cov kav dej tau hais tseg tias kauv submerged arc vuam tsuas yog siv tau rau hauv qeb III thiab IV thaj chaw.
