BW 3D Luj Tshib A234 WPB
BW 3D Luj tshib yog muaj taub hau welded (bw) stittings seatred (bw) stored worded
BW 3D Luj tshib yog ib hom lauj kaub tshib tuaj yeem faib rau 90 degbe.234 WPB yog tus txheej txheem American rau cov roj carbon hlau welded yeeb nkab fittings.
BW 90 Degree Lub luj tshib yog tsim los ntawm kev sib sau kub thiab txuas cov yeeb nkab steel lossis lwm yam yeeb nkab fittings los ntawm pob tw txheem vuam. Nws txoj haujlwm yog hloov cov kev taw qhia ntawm cov kua dej los ntawm 90 degrees, yog li nws tseem yog hu ua Lahaj Luj Tshib.
Qhov kawg ntawm pob tw wittings txuas nrog cov yeeb nkab system los ntawm pob tw vuam.bw fittings muab los ntawm ntau cov txheej txheem tsim kom tau txais cov duab ntawm cov yeeb nkab fittings.
Muaj ob hom taub qab welded luj tshib: ntev radius (lr) thiab luv vojvoog (sr).
Ntev Luv Luj Tshib
Ntev ntev radique luj tshibe yog hais txog cov yeeb nkab sab nraud uas hla nrog lub vojvoog ntawm curvature sib npaug rau 1.5 zaug, i.e r = 1.5d.
Luv luv hluav taws xob
Luv luv hluav taws xob luj tshib txhais tau tias nws lub vojvoog ntawm curvature yog sib npaug rau sab nraud ntawm lub raj, i.e r = 1.0d.
45 degree luj tshib vs 90 Degree Luj Tshib
- Txoj haujlwm ntawm 45 degree ntev radius lauj tshib lauj kaub li 90 degrees ntev thiab ntsuas thiab ntsuas me me, tab sis qhov ntev yog qhov sib txawv ntawm qhov 90 degree thiab lub luj tshib ntev.
- Lub vojvoog ntawm ob qho 45 degree thiab 90 degree ntev thiab luv luv thiab lub chaw luv yog tib yam li cas txawm li cas los xij, tsis sib npaug vim yog cov qib me me ntawm khoov.
- Piv nrog 90 Degree Luj tshib, 45 degree Luj tshib tsim cov kev sib txhuam tsawg dua thiab qis dua.
