Txo cov fittings yog cov khoom sib txuas hauv cov kav dej, feem ntau yog siv los txuas cov kav dej ntawm cov kab sib txawv, ua kom muaj kev hloov pauv dej. Lawv cov qauv tsim muaj txiaj ntsig zoo txo qis hauv cov kav dej thiab txhim kho kev sib kis.
Cov khoom lag luam cov ntsiab lus ntawm kev txo cov fittings yog qhov tseem ceeb hauv lawv cov ntaub ntawv, qhov ntev, thiab cov qauv. Cov khoom siv feem ntau suav nrog cov hlau tsis muaj steel, carbon hlau, tooj liab, thiab yas, nrog rau cov khoom sib txawv tsim nyog rau qhov chaw ua haujlwm sib txawv thiab kev tshaj tawm. Nyob rau hauv cov nqe lus ntawm qhov ntev, txo fittings feem ntau yog cim raws li "loj kawg txoj kab uas hla × me kawg txoj kab uas hla," piv txwv li, DN50 × DN32, qhia tias ib kawg muaj ib txoj kab uas hla ntawm 50 hli thiab lwm kawg yog 32 hli. Structurally, txo fittings muab faib ua concentric thiab eccentric hom. Concentric txo fittings tswj cov yeeb nkab qhov chaw nruab nrab, thaum eccentric txo fittings yog siv nyob rau hauv cov xwm txheej uas yuav tsum tau tiv thaiv cov kua tsub zuj zuj los yog venting.
Manufacturing txheej txheem cov yam ntxwv yog lub hauv paus ntawm kev txo kom haum manufacturing. High-zoo txo fittings feem ntau ntiav precision casting los yog forging txheej txheem los xyuas kom meej ib tug du, burr -dawb sab hauv, txo cov dej tsis kam. Vuam txheej txheem kuj tseem ceeb heev, tshwj xeeb tshaj yog rau stainless hlau txo cov pob qij txha, yuav tsum tau welds tsis muaj porosity los xyuas kom meej sealing thiab lub zog. Tsis tas li ntawd, kev kho deg xws li galvanizing thiab hmoov txheej tuaj yeem txhim kho qhov sib koom ua ke ntawm kev tiv thaiv corrosion thiab txuas ntxiv nws lub neej kev pab cuam.
