Buttweld Fittings General

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 nyob rau 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 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 sab hauv 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

Bevelled Ends

Qhov kawg ntawm tag nrho cov buttweld fittings yog bevelled, tshaj phab ntsa thickness 4 hli rau austenitic stainless hlau, los yog 5 hli rau ferritic stainless hlau. Cov duab ntawm bevel nyob ntawm qhov tseeb phab ntsa thickness. Qhov no bevelled xaus yog xav tau kom muaj peev xwm ua "Butt weld".

ASME B16.25 npog qhov kev npaj ntawm buttwelding kawg ntawm cov kav dej txuas mus rau hauv cov kav dej los ntawm kev vuam. Nws suav nrog cov kev cai rau vuam bevels, rau sab nraud thiab sab hauv shaping ntawm hnyav-phab ntsa Cheebtsam, thiab rau kev npaj ntawm sab hauv kawg (nrog rau qhov ntev thiab qhov ntev ntev). Cov txheej txheem kev npaj weld ntug no kuj tau muab tso rau hauv ASME cov qauv (xws li, B16.9, B16.5, B16.34).

Khoom siv thiab kev ua haujlwm

Cov khoom siv feem ntau siv hauv fittings tsim yog carbon steel, stainless hlau, cam khwb cia hlau, aluminium, tooj liab, iav, roj hmab, ntau yam yas, thiab lwm yam.

Tsis tas li ntawd, fittings, zoo li cov kav dej, rau lub hom phiaj tshwj xeeb qee zaum hauv nruab nrog cov txheej txheem ntawm cov khoom sib txawv kiag li raws li qhov haum rau lawv tus kheej, uas yog "lined fittings".

Cov khoom siv ntawm kev sib haum xeeb yog qhov tsim nyog thaum xaiv cov yeeb nkab, feem ntau, ib qho haum yog cov khoom siv tib yam li cov yeeb nkab.
