Lub cev yog dab tsi?
Cov yeeb nkab yog qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
Qhov tseem ceeb tshaj plaws rau cov yeeb nkab yog qhov sab nraud (OD) nrog rau phab ntsa thickness (WT). OD rho tawm 2 zaug WT (seem) txiav txim siab sab hauv txoj kab uas hla (ID) ntawm cov yeeb nkab, uas txiav txim siab lub peev xwm ntawm cov yeeb nkab.
Tube yog dab tsi?
Lub npe lub raj yog hais txog puag ncig, square, duab plaub thiab oval hollow seem uas yog siv rau cov cuab yeej siv siab, rau kev siv tshuab, thiab rau cov cuab yeej ntsuas.Cov raj yog qhia nrog sab kab thiab phab ntsa thickness, nti los yog millimeters.
Cov yeeb nkab tsuas yog muab nrog ib sab hauv (nominal) txoj kab uas hla thiab "s teem caij" (uas txhais tau tias phab ntsa thickness). Txij li thaum cov yeeb nkab yog siv los hloov cov kua los yog roj, qhov loj ntawm qhov qhib los ntawm qhov uas cov kua los yog roj tuaj yeem hla tau yog qhov tseem ceeb tshaj li qhov ntev ntawm cov yeeb nkab.Tube ntsuas, ntawm qhov tod tes, yog muab raws li sab nraud txoj kab uas hla thiab teeb tsa ntawm phab ntsa tuab.
Tube muaj nyob rau hauv kub dov hlau thiab txias dov hlau. Cov yeeb nkab feem ntau yog cov hlau dub (kub dov). Ob yam khoom tuaj yeem galvanized. Muaj ntau yam khoom siv los ua cov kav dej. Tubing yog muaj nyob rau hauv carbon steel, tsis tshua muaj alloy, stainless hlau, thiab npib tsib xee-alloys; steel tubes rau txhua yam kev siv yog feem ntau ntawm carbon steel.
Loj
Cov yeeb nkab feem ntau muaj nyob rau hauv qhov loj dua li cov raj. Rau cov yeeb nkab, NPS tsis phim qhov tseeb txoj kab uas hla, nws yog ib qho kev qhia ntxhib. Rau cov raj, qhov ntev yog qhia hauv inches los yog millimeters thiab qhia qhov tseeb qhov tseeb ntawm qhov hollow seem. Cov yeeb nkab feem ntau yog tsim los rau ib qho ntawm ntau cov qauv kev lag luam, ob qho tib si thoob ntiaj teb lossis lub teb chaws, muab kev sib raug zoo thoob ntiaj teb, uas ua rau kev siv cov fittings xws li lub luj tshib, tees, thiab couplings ua tau zoo dua. Tube feem ntau yog tsim los rau kev cai configurations thiab qhov ntau thiab tsawg siv ntau yam diameters thiab tolerances thiab txawv thoob ntiaj teb.
