Cov yeeb nkab fittings yog cov ntsiab lus dav dav rau cov khoom siv hauv cov kav dej siv rau kev sib txuas, kev tswj, kev hloov pauv, kev hloov pauv, kev sib khi thiab kev txhawb nqa [1]. Cov khoom muaj xws li hlau, stainless hlau, thiab yas. Raws li cov qauv, lawv tuaj yeem muab faib ua pob tw vuam, qhov (socket) vuam, threaded, thiab flange hom. Lawv qhov kev ua tau zoo cuam tshuam ncaj qha rau kev nyab xeeb thiab kev ua haujlwm ntawm cov kav dej.
Raws li lawv siv, lawv tuaj yeem muab faib ua rau 6 pawg: hom kev sib txuas (xws li flanges), hom kev hloov pauv (xws li lub luj tshib), thiab txoj kab uas hla hloov hom (xws li reducers). Txoj kev sib txuas npog cuaj hom, suav nrog vuam, threaded, thiab clamping. Hlau thiab tsis yog -cov khoom siv hlau tuaj yeem hloov mus rau qhov sib txawv ntawm cov xov xwm thiab cov kev xav tau siab thiab tau siv dav hauv petrochemical, engineering engineering, nuclear zog, thiab kev lag luam shipbuilding. Cangzhou, Tuam Tshoj, tau tsim ib pawg tsim khoom raws li tshwj xeeb steel thiab yas yeeb nkab fittings, txhawb kev lag luam rau siab -kawg txoj kev loj hlob.
Cov yeeb nkab haum tus qauv tau pib muab faib ua ob lub tshuab loj: European (DIN) thiab Asmeskas (ANSI). ISO 7005-1 tus qauv thoob ntiaj teb tau muab tso rau hauv ob qho tib si hauv xyoo 1992 [1]. Tuam Tshoj tau maj mam tsim cov qauv ntawm lub teb chaws (GB / T) npog cov kev tsim thiab kev soj ntsuam cov cai rau steel thiab yas yeeb nkab fittings, uas yog siv nyob rau hauv parallel nrog thoob ntiaj teb cov qauv xws li ASME thiab DIN, txhawb standardization ntawm thoob ntiaj teb pipeline engineering technology.
