Product Description

LSAW (Longitudinal Submerged Arc Vuam) cov yeeb nkab steel yog ib hom welded steel yeeb nkab uas ua los ntawm lawv cov txheej txheem tsim khoom tshwj xeeb thiab ntau yam kev siv.Cov kav dej no yog tsim los ntawm kev tsim cov hlau phaj rau hauv cov duab cylindrical thiab longitudinally welding nws siv submerged arc vuam cov tswv yim.Ntawm no yog cov ntsiab lus ntawm LSAW steel kav:

Kev tsim khoom:
● Plate Preparation: High-quality steel daim hlau raug xaiv raws li cov kev cai tshwj xeeb, kom ntseeg tau tias cov khoom siv kho mob xav tau thiab tshuaj muaj pes tsawg leeg.
● Kev tsim: Cov hlau phaj yog zoo li tus cylindrical yeeb nkab los ntawm cov txheej txheem xws li dabtsi yog khoov, dov, los yog nias (JCOE thiab UOE).Cov npoo yog pre-curved kom yooj yim vuam.
● Welding: Submerged arc welding (SAW) yog ua haujlwm, qhov twg ib qho arc yog khaws cia nyob rau hauv ib txheej flux.Qhov no tsim cov welds zoo nrog qhov tsis xws luag thiab fusion zoo heev.
● Kev tshuaj xyuas Ultrasonic: Tom qab vuam, kev kuaj ultrasonic yog ua los xyuas kom muaj kev cuam tshuam sab hauv lossis sab nraud hauv thaj chaw vuam.
● Kev nthuav dav: Cov yeeb nkab tuaj yeem nthuav dav kom ua tiav qhov xav tau txoj kab uas hla thiab phab ntsa tuab, txhim kho qhov tseeb qhov tseeb.
● Kev Tshawb Fawb Kawg: Kev sim ua tiav, suav nrog kev tshuaj xyuas qhov muag, kev kuaj xyuas qhov ntev, thiab kev ntsuas cov khoom siv tshuab, ua kom cov yeeb nkab zoo.

Qhov zoo:
● Nqi-Efficiency: LSAW cov kav dej muab cov kev daws teeb meem zoo rau cov kav dej loj thiab cov qauv siv vim lawv cov txheej txheem tsim tau zoo.
● High Strength: Txoj kev vuam ntev ntev ua rau cov kav dej muaj zog thiab cov khoom siv sib xws.
● Dimensional Accuracy: Cov kav dej LSAW nthuav tawm qhov ntev, ua rau lawv haum rau cov ntawv thov nrog kev ua siab ntev.
● Weld Quality: Submerged arc welding tsim cov welds zoo nrog fusion zoo heev thiab qhov tsis xws luag.
● Versatility: LSAW kav yog siv nyob rau hauv ntau yam lag luam, nrog rau cov roj thiab roj, kev tsim kho, thiab dej, vim yog lawv adaptability thiab durability.

Hauv cov ntsiab lus, LSAW steel kav yog tsim los siv cov txheej txheem meej thiab muaj txiaj ntsig, ua rau muaj ntau yam, siv tau zoo, thiab cov kav dej ruaj khov tsim nyog rau ntau hom kev lag luam.
