LSAW steel yeeb nkab (Longitudinally Submerged Arc Vuam), tseem hu ua ncaj seam submerged arc welded steel yeeb nkab, yog siab -kev ua haujlwm cov yeeb nkab tsim los ntawm ib qho nruab nrab- tuab steel daim hlau. Kev tsim khoom yog tsim cov phaj rau hauv cov yeeb nkab zoo thiab vuam siv ob -sab submerged arc vuam txheej txheem, ua raws li cov tshuab txias txias. Qhov no ua rau cov khoom lag luam nrog superior weld kev ncaj ncees, yam ntxwv zoo heev toughness, plasticity, uniformity, thiab ntom.

kev tsim khoom

Ntsiab nta & qhov zoo

‌

* Loj kab thiab tuab phab ntsa:LSAW kav dej feem ntau yog tsim nyob rau hauv loj diameters (feem ntau: 406.4 mm mus rau 1620 mm, nrog siab tshaj plaws ntev mus txog 12.2m) thiab nrog tuab phab ntsa (xws li, 8mm mus rau 50mm), ua rau lawv haum rau siab - siab daim ntaub ntawv.

* ‌JCOE Kev Ua Haujlwm:Cov phaj yog zoo li tus J-C-O ib ntus, ces welded thiab nthuav. JCO txoj kev yog kev ua haujlwm siab, uas hloov cov txheej txheem ntawm cov yeeb nkab steel los ntawm ob kauj ruam ntawm UO ua rau ntau kauj ruam. Nyob rau hauv txoj kev tsim, cov hlau phaj muaj cov yam ntxwv deformation, me me residual kev nyuaj siab thiab tsis muaj khawb ntawm qhov chaw.

*‌ High Strength thiab Durability:Ob chav Submerged Arc Vuam yog welded ob sab hauv thiab sab nraud, lub seam yog me ntsis thicker dua cov yeeb nkab lub cev, nws muaj zog ua tau zoo dua lwm yam vuam (xws li ERW)

*‌ Uniform Stress Distribution:Qhov ncaj longitudinal weld muab qhov sib txawv ntawm kev ntxhov siab ntau dua piv rau cov welds.

Cov ntawv thov tseem ceeb

‌
LSAW cov kav dej feem ntau yog siv los tsim cov loj - txoj kab uas hla, tuab - cov kav dej txuas rau ntev - kis tau tus mob roj thiab roj.

Raws li API cov qauv, lawv yog hom yeeb nkab tsim rau cov kav dej tseem ceeb uas dhau los ntawm qhov chaw hnyav, suav nrog siab - thaj chaw siab txias, thaj chaw hauv qab hiav txwv, thiab thaj chaw muaj neeg nyob hauv nroog.
