Txoj kev tsim khoom
High-frequency ncaj seam welded yeeb nkab txheej txheem: Xaiv cov sawb hlau uas ua tau raws li API 5L L360 tus qauv, thiab siv lub tshuab ua kom maj mam khoov cov hlua hlau rau hauv cov qauv ntawm cov yeeb nkab ncaj seam steel. Hauv cov txheej txheem no, lub vojvoog dabtsi yog khoov thiab lub kaum sab xis yog tswj xyuas kom meej qhov tseeb. Tom qab ntawd, cov cua sov uas tsim los ntawm cov high-frequency tam sim no yog siv los vuam cov yeeb nkab steel pob qij txha. Thaum lub sij hawm welding, lub high-frequency tam sim no, vuam ceev, electrode siab thiab lwm yam tsis yog ua tib zoo teem los xyuas kom meej qhov zoo ntawm cov vuam. Tom qab welding, lub vuam yog ntxuav, polished thiab qhov siab tshaj yog tswj kom cov nto du thiab tiaj tus. Tom qab ntawd, lub tshuab sizing thiab straightening tshuab yog siv los txhim kho qhov tseeb qhov tseeb, roundness thiab straightness ntawm cov yeeb nkab steel feem. Thaum kawg, kev kuaj ultrasonic, kuaj X-ray thiab lwm yam txhais tau tias yog siv los ua qhov kev sim tsis muaj kev puas tsuaj ntawm cov khoom siv thiab niam txiv, thiab cov yeeb nkab steel raug txiav raws li qhov xav tau thiab ua tiav raws li qhov xav tau.
Submerged arc vuam ncaj seam steel yeeb nkab txheej txheem: Siv steel phaj ua raw khoom, thawj zaug ua tag nrho phaj ultrasonic tshuaj xyuas kom ntseeg tau tias cov hlau phaj tsis muaj qhov tsis xws luag. Tom qab ntawd siv lub tshuab milling rau ob sab milling ntawm ob lub npoo ntawm cov hlau phaj kom ua tiav cov phaj dav dav, phaj ntug parallelism thiab groove puab. Tom qab ntawd siv lub tshuab ua ntej khoov los ua ntej khoov lub phaj ntug. Ntawm JCO txoj kev tshuab, ib nrab ntawm cov hlau phaj yog nias rau hauv "J" zoo, thiab ib nrab yog nias rau hauv "C" zoo, thiab thaum kawg ua "O" zoo li. Tom qab ntawd, lub vuam yog pre-welded los txhim kho qhov vuam, thiab tom qab ntawd longitudinal multi-wire submerged arc vuam yog siv los vuam sab hauv thiab sab nraud ntawm cov yeeb nkab steel feem ua kom cov vuam ntau ruaj thiab zoo ib yam. Tom qab vuam, cov vuam thiab cov ntaub ntawv niam txiv ntawm ob sab yog ultrasonically thiab X-rayed, thiab tom qab ntawd tag nrho ntev ntawm cov yeeb nkab steel tau nthuav dav los txhim kho qhov tseeb qhov tseeb thiab sab hauv kev ntxhov siab. Tom qab ntawd, kev ntsuas dej siab tau ua tiav los xyuas kom meej lub zog thiab kev sib khi, thiab cov yeeb nkab kawg tau ua tiav thiab tshuaj xyuas dua kom ntseeg tau tias qhov zoo ntawm cov yeeb nkab kawg ua tau raws li tus qauv.
Daim ntawv thov teb
L360 ncaj seam steel yeeb nkab yog dav siv hauv kev thauj mus los hauv kev lag luam xws li roj thiab roj. Vim nws lub zog siab thiab zoo corrosion kuj, nws tuaj yeem tiv taus qhov kub thiab txias, yog li nws ua lub luag haujlwm tseem ceeb hauv kev thauj mus los hauv cov kav dej, cov roj av, cov roj av extraction, thiab lwm yam. Tsis tas li ntawd, vim nws cov kev ua haujlwm zoo heev los tiv thaiv corrosion, L360 ncaj seam steel yeeb nkab kuj tau siv dav hauv marine engineering thiab khoom siv tshuaj.
