ASTM A500 inotonhora-yakaumbwa yakakwenenzverwa uye isina musono kabhoni simbi yekumisikidza tubing kune yakasungirirwa, riveted, kana bhaudhi zambuko uye zvivakwa zvekuvaka uye zvakajairwa zvimiro zvinangwa.
Pombi yeGrade C nderimwe remagiredhi rine goho repamusoro risingasviki 345 MPa uye simba rekusimba risingasviki 425 MPa.
Kana iwe uchida kuziva zvakawanda nezveASTM A500, unogona kudzvanya kuti utarise!
ASTM A500 inoronga simbi pombi kuita mamakisi matatu,giredhi B, giredhi C, uye giredhi D.
CHS: Zvikamu zvedenderedzwa.
RHS: Sikweya kana rectangular hollow zvikamu.
EHS: Elliptical hollow zvikamu.
Simbi ichagadzirwa neimwe kana kupfuura yeanotevera maitiro:okisijeni yakakosha kana choto chemagetsi.
Iyo tubing ichagadzirwa naisina musonokana welding process.
Welded tubing ichagadzirwa kubva simbi-yakatenderedzwa nemagetsi-resistance-welding process (RW).Iyo longitudinal butt joint ye welded tubing ichabatanidzwa mukati mekukobvu kwayo nenzira yekuti simba redhizaini rechikamu chetubhing nderechokwadi.
ASTM A500 Giredhi C inogona kuvharwa kana kusagadzikana-kurerutswa.
Anealing inopedzwa nekudziisa chubhu kusvika pakupisa kwepamusoro uye wozoitonhodza zvishoma nezvishoma.Annealing inorongazve iyo microstructure yezvinhu kuti ivandudze kusimba kwayo uye kufanana.
Kubvisa kushushikana kunowanzoitwa nekudziisa tembiricha yakadzikira (kazhinji yakadzikira pane yekuvhara) wozoibata kwenguva yakati rebei woitonhodza.Izvi zvinobatsira kudzivirira kukanganisa kana kuputika kwezvinhu panguva yekushanda kunotevera senge welding kana kucheka.
Kuwanda kwebvunzo: Zvienzaniso zviviri zvepombi zvakatorwa pachikamu chimwe nechimwe chezvidimbu 500 kana chidimbu chacho, kana kuti zvienzaniso zviviri zvezvinhu zvakatsetseka zvakapetwa zvakatorwa kubva mujenya rega rega renhamba yezvimedu zvinopetwa.
