General kev cai rau stainless hlau raj
GB / T19228-2011 yog raws GB / T12771-2008, yog li cov kev qhia hauv qab no kuj siv tau rau lwm qhov laj thawj stainless hlau raj.
Ⅰ. Qhov Coob thiab kam rau ua
Qhov Hloov: qhov taub loj tuaj yeem tso cai sib txawv C yog ± 0.5% D, DN150-300, 0.75% D hauv qab DN150;
Thickness: Tso cai sib txawv: ± 10% S;
Ntev: 3000-9000 hli, kuj tuaj yeem hloov kho raws li qhov xav tau, tso cai sib txawv: 0 ~ +20 hli;
Dabtsi Yog Khoov Qib: 2mm / M;
Txoj kab nqes: Qhov nqes ntawm lub tsev nres nkoj steel yeeb nkab yuav tsum ua kom tau raws li qhov yuav tsum tau ua nyob hauv cov lus hauv qab no.
Ⅱ. Kev Siv Lub Laws Teeb Txoj Kev
Lub taub tsis xeb hlau feem ntau xa tawm raws li qhov ntsuas qhov hnyav, thiab nws tseem tuaj yeem xa mus raws li qhov hnyav dhau tom qab kev sib ceg. Thaum xa tawm raws li theoretical hnyav, qhov theoretical weight tau muab xam raws li cov mis (I)

Stainless Hlau Qauv Tube
- Lub raj xa hluav taws xob feem ntau yog welded lub raj lossis cov qauv raj, feem ntau siv los ua tus kav tuav lossis kho kom zoo nkauj, uas nws cov khoom feem ntau 304 stainless hlau lossis zoo dua. Nws cov txheej txheem ntau lawm yog tias thawj nias qauv raj los ntawm txoj hlua khi steel, thiab tom qab ntawd tag nrho cov hlau txuas, thiab thaum kawg pickling thiab polishing.
- Nws yog feem ntau cov qauv pob zeb diamond los yog lub voj voos txawv, txais yuav steel sawb embossing thiab steel kauj tsim vuam.
Nws txoj kab uas hla feem ntau 22mm-48mm, lub ntsiab thov: tsev kho kom zoo nkauj, ntaiv tus pas hlau tuav, tus tes tuav, tsheb tes, thiab lwm yam.
