Kev faib tawm ntawm Carbon Steel Luj Tshib Ntau yam

Carbon steel luj tshib yog thawj cais raws li lawv curvature vojvoog, uas yuav muab faib ua lub vojvoog ntev lub luj tshib thiab luv luv vojvoog luj tshib. Lub luj tshib ntev yog hais txog cov yeeb nkab uas muaj lub voj voos curvature sib npaug li 1.5 npaug ntawm txoj kab uas hla ntawm cov yeeb nkab, piv txwv li R=1.5D. Lub luj tshib luv luv yog hais txog lub voj voos curvature sib npaug rau sab nraud ntawm cov yeeb nkab, piv txwv li R=1.0D. (D yog txoj kab uas hla ntawm lub luj tshib, R yog lub vojvoog ntawm curvature. D kuj tuaj yeem qhia tau ntau yam.) Yog tias muab faib los ntawm qib siab, muaj kwv yees li kaum xya hom, uas yog tib yam li Asmeskas cov qauv yeeb nkab, suav nrog: Sch5s. , Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, nrog rau feem ntau yog STD thiab XS. Raws li lub kaum sab xis ntawm lub luj tshib, muaj 45 degree luj tshib, 90 degree luj tshib, thiab 180 degree luj tshib. Cov qauv kev tswj hwm suav nrog GB/T12459-2005, GB/T{24}}, GB/T{25}}, HG/T21635-1987, D-GD0219, thiab lwm yam.
