ASTM A335 Seamless Yeeb Nkab, Ib txoj hlua ntev ntawm cov hlau nrog ib qho hollow seem thiab tsis muaj seams nyob ib ncig ntawm nws.Cov yeeb nkab steel muaj qhov hollow seem thiab yog dav siv rau kev xa cov kav dej, xws li xa cov roj, roj, roj, dej thiab qee yam khoom siv.Alloy seamless steel yeeb nkab thiab puag ncig steel thiab lwm yam khoom hlau, nyob rau hauv flexural thiab torsional lub zog tib lub sij hawm, qhov hnyav yog sib dua, yog ib hom kev lag luam steel, dav siv nyob rau hauv kev tsim khoom ntawm cov qauv thiab cov khoom siv kho tshuab, xws li roj. tsheb thauj mus los, stair handrails, tsheb kauj vab ncej thiab kev tsim kho ntawm steel scaffolding.Ua cov nplhaib nrog cov hlau tsis muaj steel yeeb nkab tuaj yeem txhim kho kev siv cov khoom siv, ua kom yooj yim tsim cov txheej txheem, txuag cov khoom siv thiab ua lub sijhawm, xws li dov bearing nplhaib, lub tes tsho jack, thiab lwm yam, tau siv dav hauv kev tsim cov yeeb nkab steel.Alloy seamless steel yeeb nkab los yog txhua yam ntawm cov pa riam phom indispensable khoom, chim, chim thiab thiaj li nyob rau steel yeeb nkab los tsim.Tsis tas li ntawd, cov seem annular nyob rau hauv sab hauv lossis sab nraud radial siab, lub zog ntau dua, yog li ntawd, feem ntau ntawm cov hlau tsis muaj seamless steel raj yog puag ncig.
ASTM A335 Seamless Yeeb Nkab, Cov Txheej Txheem Ntau Lawm
Kub dov (extruded seamless steel raj): round tube billet → cua sov → perforation → peb-yob cross dov, nruam dov los yog extrusion → raj stripping → sizing (los yog txo) → txias → blank raj → straightening → dej siab kuaj (los yog tsis xws luag nrhiav) → cim → cia.
Cold drawing (rolling) seamless steel tube: round tube billet → cua sov → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass txias drawing (txias dov) → blank tube → heat treatment → straightening → water pressure test (Kev kuaj pom qhov tsis haum) → kos npe → khaws cia
