API 5L X42 welded steel yeeb nkab qhia tau zoo heev kev pab cuam efficiency thiab durability nyob rau hauv lub zog kis tau tus mob, ua tsaug rau nws balanced mechanical zog thiab optimized manufacturing txheej txheem.
Cov yeeb nkab yog tsim los ntawm High-Frequency Resistance Welding (ERW) technology, qhov twg 150-400 kHz siab- zaus tam sim no ua tiav cov hlau fusion tam sim. Qhov no yog ua tiav los ntawm kev saib xyuas dual ntawm online eddy kev sim tam sim no thiab kev tshuaj xyuas ultrasonic, ua tiav qhov kev kuaj pom qhov tsis zoo txog li 99.97%, ua kom ruaj khov weld zoo. Thaum lub sij hawm tsim khoom, nruab nrab - zaus induction cua sov thev naus laus zis tswj cov vuam cheeb tsam kub txog 50-80℃saum toj ntawm Ac3 theem kev hloov pauv, tshem tawm cov kev ntxhov siab ntawm cov vuam seem. Coupled nrog lub siab automated tswj chav tsev (ntau npaum li cas mus txog 40 meters ib feeb), cov yeeb nkab phab ntsa thickness kam rau ua yog tswj nyob rau hauv ± 0.15 hli, muab superior dimensional raug piv rau cov tsoos seamless steel kav thiab txo cov kev sib tw ntawm qhov chaw thiab kev sib tw.
NPS: 1/2 "mus rau 48" Sab Nraud Diamter
WT : XS, Sch. 10 to 160, STD, XXS.
