Ua ntej ntawm tag nrho cov, cia peb nkag siab tias dab tsi yog American standard luj tshib, nws yog nrov hais tias American standard luj tshib yog raws li American standard ntau lawm ANSI ASME B16.9, ANSI ASME B16.28 ntawm lub collective lub npe ntawm lub luj tshib. US tus qauv luj tshib feem ntau yog siv dav hauv kev lag luam tawm txawv teb chaws thiab cov lag luam nyiaj txiag txawv teb chaws, US tus qauv luj tshib diameters yog nyob rau hauv nti, thiab lub siab yog nyob rau hauv phaus LB (chav kawm). American Standard Luj tshib tau muab faib ua kwv yees li kaum xya hom raws li qib siab, uas yog tib yam li American Pipe Standards, xws li: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS; Ntawm lawv, feem ntau siv yog STD thiab XS
Lub luj tshib American standard yog muab faib ua carbon steel thiab stainless hlau los ntawm cov khoom; Carbon Steel: (20#, A3, Q235, Q235A, Q235B, 20G, 16Mn, ASTM A234WPB, ASTM A105, thiab lwm yam); Tus Hlau Stainless: (304, 304L, s30408, s31608, {} cr103, 91CR2107, 022cr27ni12mo2 , thiab lwm yam);
