Txheem Npe & Cov Khwv
JIS G 3466:Carbon Steel Square thiab duab plaub hau rau cov qauv dav.
Lub hom phiaj:Tus qauv xov xwm Japanese kev lag luam tshwj xeeb rau welded carbon hlau, duab dhos, thiab tshwj xeeb} Kuv yog} hss) feem ntau npaj rau siv nyob rau hauvGeneral Welded, bolted, lossis riveted qauv qauvxws li cov tsev, cov choj, tsheb, cov nkoj, cov cuab yeej siv cov qauv zoo nkauj, thiab lwmyam cov khoom siv cov neeg kho tshuab yog qhov tseem ceeb ntawm kev txiav txim siab. Nws uatsisNpog cov hlua rau siab lub hom phiaj, kev hloov pauv cua sov, lossis cov neeg kho tshuab tubing.
Cov Khoom Siv & Qib
Khoom siv:Cov hlau hlau.
Cov Qib:Txhais los ntawm yam tsawg kawg yog lub zog. Thawj qeb kawm yog:
Stkr400:Yam tsawg kawg nkaus los lub zog ntawm 400 MPA (N / MMOL).
Stkr490:Yam tsawg kawg nkaus los lub zog ntawm 490 MPa (N / MMOL).
Cov lus piav qhia raug kawm qib:
- Stk: Denotes "Steel Tube Kikaku" (cov qauv hlau txheem).
- R: Sawv rau "Ryohouiki" (tawm taw tes / lub zog).
- 400 lossis 490: sawv cev rau qhov tsawg kawg yog kom muaj zog hauv MPA.
Tus "R" yog qhov tseem ceeb, uas cov kev teeb meem no los ntawm lwm cov qib STK (zoo li STK400 / 490 yam tsis muaj qhov sib txawv lossis cov ntawv thov.
Cov txheej txheem tsim khoom
Cov leeg yog tsim los ntawmKhaub TawvCa - rolled steel (kub {1} {rolled los yog txias- rolled coil / ntawv) mus rau cov square uas xav tau lossis duab plaub.
Lub longitudinal seam yogweldedSiv cov txuj ci tsim nyog rau high - ceev ntau lawm, feem ntauHluav Taws Xob Ua Chiv Fab (ERW)lossis qee zaum high - zaus induction induction. Seamless leeg yogtsisthem los ntawm tus qauv no.

Elongation (%):Yam tsawg kawg nkaus elongation tus nqi tau teev raws li lub raj loj (dav hlau tuab, dav dav), feem ntau nrog rau ntawm 15% mus rau 30%. Cov elongation ntau dua feem ntau yuav tsum muaj rau cov khoom siv thim rov qab.
Kaj ntsuam xyuas:Kev ntsuas qhov tseem ceeb rau Welded Tubes. Qhov ntev teev ntev yog flattened ntawm parallel daim hlau mus rau ib qho deb h (suav raws li phab ntsa thickness t). Weld yuav tsum tau muab tso rau ntawm 90℃lossis 0℃rau cov kev taw qhia ntawm kev quab yuam. Lub raj xa yuav tsum tau tiv thaiv cov flattening yam tsis muaj kev tawg los yog weld qhib ntau tshaj li ib qho kev txwv. Qhov kev xeem Weld kev ncaj ncees thiab kev sib luag.
Qhov seem ntev
Tus qauv txhais tau nruj nruj rau:
Sab nraum qhov ntev (qhov dav, qhov siab): piv txwv li, ± 0.5 hli mus rau ± 1.5% nyob ntawm qhov loj me.
Phab ntsa tuab: piv txwv li, ± 10% ntawm nominal tuab.
Kaum lub vojvaj: siab tshaj plaws txwv tau teev tseg.
Ntev: thev rau cov qauv thiab precision - txiav ntev.
Kev Ncaj Ncees: Qhov ntau tshaj cuam tshuam ib qho ntev.
Squaress (sib txuas ntawm ob sab).
Pawg:Kev thev tau ntawm theoretical me me rau lub ntsuas ntsuas yog teev (feem ntau ib puag ncig ± 6% rau ± 10%).
