Cov yeeb nkab fitting yog txhais tias yog ib feem siv rau hauv lub kaw lus kav dej, rau kev hloov kev taw qhia, kev ceg lossis kev hloov ntawm lub yeeb nkab txoj kab uas hla, thiab uas tau txuas nrog lub kaw lus. Muaj ntau hom fittings sib txawv thiab lawv zoo ib yam hauv txhua qhov loj me thiab cov sijhawm zoo li cov yeeb nkab.
Cov khoom siv sib txuas tau muab faib ua peb pawg:
Cov khoom siv Buttweld (BW) uas nws qhov ntev, qhov ntev thiab lwm yam tau txhais hauv ASME B16.9 cov qauv. Cov khoom siv tiv taus corrosion uas tsis hnyav yog ua rau MSS SP43.
Qhov (Socket Weld) fittings Class 3000, 6000, 9000 tau txhais nyob rau hauv ASME B16.11 cov qauv.
Cov khoom siv sib txuas (THD), cov khoom siv ntsia hlau Chav Kawm 2000, 3000, 6000 tau txhais hauv cov qauv ASME B16.11.
Cov ntawv thov ntawm Buttweld Fittings
Ib lub tshuab raj siv cov khoom siv buttweld muaj ntau qhov zoo dua li lwm hom.
Vuam ib qho khoom sib txuas rau lub yeeb nkab txhais tau tias nws tsis xau mus tas li;
Cov qauv hlau txuas ntxiv uas tsim los ntawm cov yeeb nkab thiab cov khoom sib txuas ntxiv lub zog rau lub kaw lus;
Sab hauv du thiab kev hloov pauv maj mam txo qhov kev poob siab thiab kev co thiab txo qhov kev ua ntawm kev xeb thiab kev yaig;
Ib lub tshuab welded siv qhov chaw tsawg kawg nkaus.
