Qauv Txheej txheem cej luam

JIS G3444 STK 400Puas yog tus qauv kev lag luam Japanese (JIS) cov lus qhia tshwj xeeb rau cov roj txheem siv roj carbon hlau siv hauv kev siv tshuab thiab cov qauv txheej txheem. Ntawm no yog cov ncauj lus piav qhia ntxaws ntawm nws:

Tus Qauv Qauv: JIS G3444

Lub npe: Cov pa roj carbon hlau rau cov qauv txheej txheem dav dav.

Cov ntaub ntawv tsim:Stk 400

Tus ntxhiab: Sawv rau "Txheej Txheem Tubing, Carbon Steel."

400: Qhia txog qhov tsawg kawg tensile lub zog hauv MPA (megapascals).

Cov Lus Qhia Tshwj Xeeb:

WT:1.3mm - 16 hli (ERW), 10mm- 50 hli (lsaw)
Ntev:Feem ntau siv 5.8m, 6m, 12m, lossis raws li qhov koj xav tau.
Kev kho cov npoo npoo:Txheej, kub - dip galvanized, tha xim
Daim Ntawv Thov:Civil engineering, architecture, steel yees, scaffoldings, struts, piles kev nkag siab, thiab lwm yam qauv.

ERW PIPES

Tshuaj lom neeg tshuaj lom neeg (yuav tsum tau)

Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov stk 400 hlau tubes feem ntau ua cov kev txwv hauv qab no (tej zaum yuav txawv me ntsis los ntawm chaw tsim khoom):

Carbon (c): Ntau Ntau 0.25%
Silicon (si): Tsis muaj qee yam txwv
Manganese (mn): Tsis muaj qee yam txwv
Phosphorus (p): Siab tshaj 0.040%
Sulphur (s): Siab tshaj 0.040%

Nco tseg:Qhov muaj feem sib txawv yuav txawv nyob ntawm kev tsim cov txheej txheem (piv txwv li, seamless lossis welded hlab).

Cov Khoom Siv Neeg Kho Tshuab

Lub zog tensile: Yam tsawg kawg 400 n / mm²

Paib muaj tseeb ntawm cov pov thawj kev ntxhov siab: Yam tsawg kawg ntawm 235 n / mm²

Elongation: Feem ntau ntau dua lossis sib npaug rau 20-25% (sib txawv nrog lub raj loj me thiab kev tsim khoom txoj kev).

Ntaus: 90 Degree khoov kaum ntse ntse nrog sab hauv vojvoog ntawm 6D (d yog cov taub sab nraud ntawm lub raj)

Ua kom tiaj: Deb nyob deb ntawm cov paib (h) yog 2 / 3d

Tensile lub zog hauv weld cheeb tsam: Yam tsawg kawg 400 n / mm²

Txoj kev lag luam

Tsis ntse: Cim raws li "s"
Hluav Taws Xob Ua Taub Hau Welded: Cim li "b"
Tsis siv neeg arc welded: Cim li "a"
Kub tiav: Cim raws li "h"
Txias tiav: Cim li "c"
Raws li cov hluav taws xob tiv thaiv welded: Cim li "g"

Nto tas: Feem ntau meej (dub) lossis galvanized rau corrosion tsis kam (yog tias teev).

Kuaj thiab tshuaj xyuas

Tshuaj Lom: Txhawm rau kom muaj cov tshuaj lom neeg muaj pes tsawg leeg ua tau raws li kev txwv tshwj xeeb.

Kev Kuaj Neeg Kho Tshuab: Xws li cov kev ntsuam xyuas Tensile, cov kev ntsuam xyuas kom tiaj tus, thiab cov ntawv xeem dabtsi.

Tsis - kev sim tshuaj ntsuam (ndt): Txhawm rau tshuaj xyuas rau ib qho kev cuam tshuam sab hauv.

Kuaj xyuas deg: Los xyuas kom meej tias tsis muaj qhov tsis xws luag.

Tshawb xyuas qhov seem: Kom paub tseeb tias qhov ntev ntawm cov kav dej sib ntsib kev thev taus.

Cov Ntawv Thov

Lub hom phiaj qauv txheej txheem: Tsim nyog rau cov qauv txheej txheem dav dav, kev tsim kho pej xeem, tsim kho, steel yees, scaffolding, scaffolding, scaffolding, thiab lwm yam qauv.

Lwm Yam Siv: Nws tseem tuaj yeem siv tau rau hauv ntau qhov chaw ua lag luam uas tsawg {{}} qhov kev thov hnyav yuav tsum muaj.
