ASTM A500 Qib B yog hom steel tubular uas feem ntau siv rau hauv ntau yam kev lag luam thiab kev tsim kho. Nws yog ib hom qauv steel tubing thiab yog tsim los ntawm carbon steel nrog cov ntsiab lus siab tshaj plaws ntawm 0.23%.

Qib no ntawm steel tubing muaj qhov zoo tshaj plaws lub zog-rau-qhov hnyav piv thiab yog qhov zoo tagnrho rau kev siv qhov hnyav-txuag yog qhov tseem ceeb. Nws kuj yog ib qho ruaj thiab resistant rau corrosion, ua rau nws haum rau sab nraum zoov thiab hnyav ib puag ncig.

ASTM A500 Qib B steel tubing yog siv rau ntau yam kev siv xws li kev tsim vaj tsev, tshuab, thiab khoom siv. Nws kuj yog siv nyob rau hauv kev lag luam automotive rau kev tsim cov chassis thiab ncua kev kawm ntawv.

Cov tubing steel muaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg xws li square, round, rectangular, thiab oval. Nws kuj tuaj yeem kho raws li qhov xav tau ntawm cov neeg siv khoom.

Cov khoom siv hlau tubular muaj ntau yam kev siv hauv ntau qhov kev lag luam vim lawv cov khoom siv ntau yam thiab kav ntev. Nov yog qee qhov kev siv feem ntau ntawm steel tubular khoom:

1. Kev tsim kho: steel tubular cov khoom siv dav siv hauv kev tsim kho xws li kev tsim cov choj, skyscrapers, thiab tunnels. Lawv feem ntau siv los ua cov khoom siv vim lawv lub zog compressive siab thiab ua haujlwm zoo rau sab nraud.

2. Kev lag luam roj thiab roj: Cov khoom siv hlau tubular tau siv dav hauv kev lag luam roj thiab roj los tho qhov dej, thauj roj thiab roj, thiab tsim cov kav dej. Lawv yog cov nyiam rau lawv lub peev xwm los tiv thaiv cov xwm txheej hnyav ntawm ib puag ncig, xws li qhov kub thiab txias siab.

3. Automotive kev lag luam: Cov khoom siv hlau tubular yog siv hauv kev lag luam tsheb los tsim cov chassis, thav duab, thiab cov tshuab tso pa tawm. Lub zog siab thiab kav ntev ntawm cov hlau ua rau nws yog cov khoom siv zoo heev rau cov ntawv thov no.

4. Muaj tshuab: Cov khoom siv hlau tubular tau siv dav hauv kev siv tshuab, xws li cov tshuab conveyor thiab cov cuab yeej ua haujlwm, vim lawv lub peev xwm thauj khoom siab thiab zoo heev corrosion kuj.

5. Infrastructure tej yaam num: Cov khoom siv hlau tubular yog siv rau hauv kev tsim kho vaj tse xws li kev tsheb ciav hlau, tshav dav hlau khiav, thiab kev tsim vaj tse vim lawv lub zog thiab kav ntev. Lawv xyuas kom meej tias cov phiaj xwm no tau tsim ua kom kav ntev.
