ASTM A500 Round Square ERW Steel Yeeb Nkab tshwj xeeb nta Hluav taws xob Resistance Welded (ERW) kav hauv ob qho tib siHloovthiabSquare / Rectangularhla -sections. Tsim los rau kev siv cov qauv, cov raj no muaj qhov zoo sib npaug ntawm lub zog siab, weldability zoo heev, thiab tus nqi -kev ua tau zoo, ua rau lawv xaiv rau kev tsim kho, choj lub tsev, thiab cov qauv txheej txheem.

Txheem & Qib

Ua raws liASTM A500 / A500M-23, qhov tseeb version, cov tubing muaj nyob rau hauv plaub qib thawj raws li cov khoom siv kho tshuab:

‌Qib A: Yam tsawg kawg nkaus lub zog ntawm 46 ksi (315 MPa). Haum rau kev siv lub teeb pom kev zoo.

‌Qib B: Yam tsawg kawg nkaus yield zog ntawm 46 ksi (315 MPa) rau round raj; feem ntau raug suav hais tias yog 290 MPa hauv qee qhov ntsiab lus nyob ntawm qhov loj. Qhov feem ntau siv qib rau kev siv cov qauv siv vim nws muaj ntau yam.

‌Qib C: Yam tsawg kawg nkaus yield zog ntawm 50 ksi (345 MPa) rau round raj. Qhov zoo tshaj plaws rau hnyav-cov haujlwm ua haujlwm, txuas hniav, thiab seismic-cov qauv tsim tawm.

‌Qib D: Yam tsawg kawg nkaus lub zog ntawm 36 ksi (250 MPa). Yuav tsum tau kho cua sov thiab feem ntau yog siv rau puag ncig tubing.

Nco tseg: Thaum ASTM A500 txhais cov qib A-D, cov khoom lag luam sib npaug feem ntau ua raws cov qauv khoom xws li Q235B lossis S235JR rau qib B daim ntawv thov.

Kev tsim khoom

Cov txheej txheem tsim khoom ERW suav nrog dov steel coils rau hauv cov duab tubular thiab vuam cov seam siv siab - zaus hluav taws xob tsis kam. Txoj kev no ua kom cov phab ntsa tuab zoo ib yam, zoo tshaj qhov ua tiav, thiab qhov tseeb qhov ntev ntev piv rau cov txheej txheem ib txwm muaj.

Kev kho deg & Xaus qhov kawg

Txhawm rau txhim kho cov kav ntev thiab kev tiv thaiv corrosion, muaj ntau yam kev kho saum npoo av:

‌Dub (Mill Finish): Oiled los yog liab qab, haum rau tam sim ntawd pleev xim los yog siv sab hauv tsev.

‌Kub-Dip Galvanized (HDG): Muab kev tiv thaiv corrosion zoo rau cov qauv sab nraum zoov. Zinc txheej feem ntau yog li ntawm 60 g / m² txog 120 g / m².

‌Ua ntej- Galvanized: Rau cov kev xav tau sib dua corrosion.

‌Painted / Coated: Epoxy lossis PE txheej thaum thov.

‌Hom kawg: Plain xaus, beveled xaus (rau vuam), los yog threaded thiab ua ke.

Daim ntawv thov

ASTM A500 ERW structural tubing yog dav siv thoob plaws ntau lub lag luam:

‌Kev tsim kho: steel thav duab, kab, kab, thiab trusses rau kev lag luam thiab vaj tsev nyob.

‌Infrastructure: Choj kev txhawb nqa, guardrails, thiab kev loj signage lug.

‌Kev lag luam: Machinery frames, shelving units, and agricultural khoom.

‌Architectural: Cov laj kab, tsev cog khoom thav duab, hnub ci vaj huam sib luag mounting qauv, thiab cov rooj tog hlau zoo nkauj.
