Cov yeeb nkab haum yog txhais tau tias yog ib feem siv nyob rau hauv cov kav dej, rau kev hloov cov kev taw qhia, branching los yog hloov cov yeeb nkab txoj kab uas hla, thiab uas yog mechanically koom rau hauv lub system.Muaj ntau ntau hom fittings thiab lawv yog tib yam nyob rau hauv txhua qhov ntau thiab tsawg thiab cov sij hawm raws li cov yeeb nkab.
Fittings tau muab faib ua peb pawg:
Buttweld (BW) fittings uas nws qhov ntev, qhov ntev ntev thiab lwm yam tau txhais hauv ASME B16.9 tus qauv.Lub teeb yuag corrosion resistant fittings yog tsim rau MSS SP43.
Socket Weld (SW) fittings Class 3000, 6000, 9000 yog txhais nyob rau hauv ASME B16.11 tus qauv.
Threaded (THD), screwed fittings Class 2000, 3000, 6000 yog txhais nyob rau hauv ASME B16.11 tus qauv.
Kev siv ntawm Buttweld Fittings
Lub kav dej siv cov khoom siv buttweld muaj ntau yam zoo dua li lwm cov ntaub ntawv.
Vuam ib tug haum rau cov yeeb nkab txhais tau hais tias nws yog mus tas li leakproof;
Cov qauv hlau txuas ntxiv tsim los ntawm cov yeeb nkab thiab kev sib txuas ntxiv lub zog rau lub cev;
Smooth inner nto thiab maj mam hloov cov kev taw qhia txo qis siab poob thiab turbulence thiab txo qhov kev txiav txim ntawm corrosion thiab yaig;
Lub welded system siv qhov tsawg kawg nkaus ntawm qhov chaw.
