Seamless steel yeeb nkab ntau lawm txheej txheem piav qhia
Cov txheej txheem ntawm seamless steel yeeb nkab tau muab faib ua cov kauj ruam hauv qab no: round tube billet → cua sov → tho → peb-yob cross dov, nruam dov los yog extrusion → raj tshem tawm → sizing (los yog txo) → txias → straightening → hydraulic siab Test ( los yog tsis pom kev) → cim → cia. Seamless steel kav yog ua los ntawm steel ingots los yog cov khoom tube blanks uas yog perforated rau hauv capillary hlab, thiab ces ua los ntawm kub dov, txias dov los yog txias txias.
Seamless steel kav feem ntau muab faib ua: kub dov seamless steel kav, txias-draw seamless steel kav, txias-dov seamless steel kav
Seamless steel yeeb nkab muaj qhov hollow seem thiab yog dav siv los ua cov yeeb nkab rau kev xa dej. Piv nrog cov khoom hlau xws li cov hlau puag ncig, cov yeeb nkab steel yog sib dua hauv qhov hnyav thaum khoov thiab lub zog torsional zoo ib yam. Nws yog ib qho kev lag luam hla ntu steel thiab yog siv dav hauv kev tsim cov qauv. Cheebtsam thiab cov khoom siv kho tshuab, xws li cov kav dej tho roj, lub tsheb tsav tsheb, tsheb kauj vab thav duab, thiab steel scaffolding siv hauv kev tsim vaj tsev.

Nws yog cov chaw tsim khoom loj tshaj plaws ntawm ERW thiab LSAW welded kav hauv North China.
Lub tuam txhab tam sim no muaj German advanced ntau lawm technology, peb loj-inch ob-sided longitudinal submerged arc vuam kab ntau lawm, muaj ISO9000 system ntawv pov thawj, tshwj xeeb cov cuab yeej xeem ntawv pov thawj (GB/T9711-2017 PSL2, L485M thiab hauv qab steel qib; ASTM A672 / A672M-2019, cov khoom siv C70 (A516 Gr.70) thiab qis dua qib steel; ASTM A671 / A671M-2019, khoom siv CC70 (A516 Gr.70) thiab qis dua qib steel), API 5L PSL2 X80M, API 2B, EU CE certification (CPR, PED, BC1) thiab lwm yam kev tsim nyog.
Cov khoom siv tseem ceeb suav nrog steel phaj ntug milling tshuab, tshuab ua ntej khoov, tsim tshuab, American puv-digital Lincoln vuam system, on-line tsis siv neeg ntsuas ultrasonic, on-line X-ray flaw nrhiav khoom, puv raj ntev txias expansion tshuab, hydraulic kuaj tshuab, chamfering tshuab, thiab lwm yam., tuaj yeem tsim LSAW nrog ib txoj kab uas hla ntawm 406-1422.4mm, thickness ntawm 8-50mm, thiab ib tug ntev ntawm tsawg tshaj li 14 meters.
