AS/NZS 1163 yog tus qauv tsim los ntawm Standards Australia thiab Standards New Zealand.
Tus txheej txheem qhia txog cov kev cai rau kev tsim thiab muab cov khoom txias tsim, Hluav Taws Xob Hluav Taws Xob Vuam (ERW), steel hollow seem rau kev tsim qauv.Cov seem hollow no feem ntau yog siv rau hauv kev tsim kho thiab kev siv engineering rau ntau yam qauv xws li vaj tse, txuas hniav, thiab kev tsim kho vaj tse.
Peb qib tau muab cais raws li qhov tsawg kawg nkaus tawm los muaj zog thiab ua tiav ntawm 0 ° C cuam tshuam.

kub dov coil los yog Cold-dov coil.
Fine-grained steel yog teev raws li raw khoom rau steel coils.
Cov seem hollow tiav yog tsim los siv cov txheej txheem txias txias thiab cov npoo ntawm cov hlau sawb tau koom nrog sivHluav taws xob tsis kam vuam (ERW)tshuab.
Thiab yuav tsum tshem tawm cov welds ntau dhau ntawm sab nrauv;sab hauv yuav raug tso tseg tsis huv.
Cov tshuaj muaj pes tsawg leeg ntsuas cov tshuaj muaj pes tsawg leeg ntawm cov khoom siv raw ntawm cov khoom tiav.AS / NZS 1163 tsis muaj qhov yuav tsum tau ua rau kev ntsuas cov tshuaj muaj pes tsawg leeg ntawm cov khoom tiav.
Kev muab cov khoom tensile yog ib qho tseem ceeb ntawm AS / NZS 1163, uas suav nrog lub zog tensile, yield zog, elongation, thiab lwm yam tsis tseem ceeb ntawm cov hlau, muab cov ntaub ntawv yooj yim thiab cov qauv siv rau engineering tsim thiab kev tsom xam cov qauv.

Kev soj ntsuam loj ntawm cov yeeb nkab steel feem ntau suav nrog cov khoom hauv qab no:
Txoj kab uas hla thiab phab ntsa thickness, ntev, ncaj, ovality, thiab nto zoo.
Steel yeeb nkab bevel kaum
Cov yeeb nkab phab ntsa thickness
Sab nraud txoj kab uas hla ntawm cov yeeb nkab steel
Raws li cov neeg siv khoom xav tau, kev tiv thaiv corrosion ntawm steel yeeb nkab nto tuaj yeem ua tau ntau txoj hauv kev los txhim kho nws cov kev tiv thaiv corrosion thiab ua kom nws lub neej ntev.
Xws li cov kua roj vanish, xim, galvanization, 3PE, FBE, thiab lwm yam.
Peb yog ib qho ntawm cov ua welded carbon steel yeeb nkab thiab seamless steel yeeb nkab manufacturers thiab cov neeg muag khoom los ntawm Tuam Tshoj, nrog rau ntau yam zoo steel yeeb nkab hauv Tshuag, peb tau cog lus los muab koj ntau yam kev daws teeb meem ntawm cov yeeb nkab steel.
Xav paub ntau ntxiv txog cov khoom lag luam, thov koj xav tiv tauj peb, peb tos ntsoov yuav pab koj nrhiav cov kev xaiv zoo tshaj plaws steel yeeb nkab rau koj cov kev xav tau!
