ANSI / ASME B16 9 180 Lub luj tshib
ANSI/ASME B16. Nws lub vojvoog ntawm curvature R feem ntau yog tsawg dua lossis sib npaug li 3 npaug ntawm cov yeeb nkab txoj kab uas hla D. Feem ntau siv yog lub luj tshib ntev nrog R=1.5D thiab R =1D luv luv lub luj tshib 1.
Hom lub luj tshib no feem ntau yog siv qhov kev taw qhia ntawm cov yeeb nkab yuav tsum tau hloov. Nws lub kaum sab xis yog 180 degrees, uas tuaj yeem ua rau cov kev taw qhia ntawm cov yeeb nkab tsis sib haum. Tsis tas li ntawd, raws li ntau hom kev sib txuas, lub luj tshib kuj tuaj yeem muab faib ua ntau hom xws li pob tw vuam luj tshib, lub luj tshib, thiab lub luj tshib threaded.
Stainless hlau 180-degree lub luj tshib yog siv los txuas cov kav dej ntawm ntau txoj kab uas hla thiab siv rau hauv tshuaj lom neeg, kev tsim kho, cement, nkoj tsim thiab lwm yam lag luam. 180 degree luj tshib carbon steel yog li ntawd nyob rau hauv siab thov thiab yog siv nyob rau hauv chemical kev lag luam, engineering kev lag luam thiab ntau lwm yam lag luam.
