IbASME B16.11 SW capyog ib qho forged haum tsim kom haum tshaj qhov kawg ntawm cov yeeb nkab. Tsis zoo li lub pob tw -weld cap-uas dlhos ntug- rau-ntug- lub qhov (socket weld cap) nta lub qhov (socket) recessed bore qhov twg cov yeeb nkab zaum ua ntej yuav fillet -welded nyob ib ncig ntawm cov txheej ncig.
Cov fittings no feem ntau tsim nyob rau hauv peb chav kawm siab, tab sis lub kaus mom feem ntau tau teev tseg hauv ob:
- Chav Kawm 3000:Txheem lub luag haujlwm rau siab -siab tshuab (pairs nrog Schedule 80/XS yeeb nkab).
- Chav Kawm 6000:Lub luag haujlwm hnyav rau huab cua siab / qhov kub thiab txias (pairs nrog Schedule 160 yeeb nkab).
- Chav Kawm 9000:Lub luag haujlwm hnyav ntxiv (tsawg dua, ua ke nrog Teem caij XXS yeeb nkab).
Ntsiab Dimensional Parameters piav qhia
Thaum saib ntawm cov chaw tsim khoom catalog lossis engineering kos duab rau ASME B16.11 SW cap, koj yuav ntsib cov lej tshwj xeeb:
NPS (Nominal Pipe Size):Txheeb xyuas cov yeeb nkab loj (1/8 "mus txog 4").
Qhov (socket) Diameter:Sab hauv txoj kab uas hla ntawm lub qhov (socket) qhib qhov twg cov yeeb nkab nkag mus.
Qhov (socket) qhov tob:Qhov tsawg kawg nkaus qhov tob ntawm daim di ncauj ntawm qhov haum rau lub xub pwg sab hauv.
Ntev Cap:Tag nrho qhov siab / ntev ntawm qhov haum.
Sab nraud txoj kab uas hla:Tag nrho sab nraud txoj kab uas hla hla lub forged lub cev.
Phab ntsa Thickness:Qhov nruab nrab thiab tsawg kawg nkaus thickness ntawm lub hau lub cev thiab phab ntsa kawg.
Common Material Qib rau B16.11 Caps
Forged SW caps yog tsim los ntawm ntau yam khoom siv tshwj xeeb nyob ntawm cov txheej txheem xov xwm:
Carbon Steel:ASTM A105 (feem ntau yog rau cov roj, roj, thiab kev pabcuam dej ambient), ASTM A350 LF2 (tsawg-kev siv kub).
Stainless hlau:ASTM A182 F304 / 304L, F316 / 316L (kev ua tshuaj lom neeg, chaw huv huv, kev siv dej hiav txwv).
Hlau alloy:ASTM A182 F11, F22, F91 (siab-kub fais fab nroj tsuag kav).
Nickel Alloys:Inconel, Hastelloy, Monel (ib puag ncig corrosive heev).
Tswv yim Sourcing & Verification Checklist
Thaum xaj lossis tshuaj xyuas ASME B16.11 SW caps ntawm -site, xyuas cov hauv qab no:
MTR (Cov ntaub ntawv xeem cov ntaub ntawv):Paub meej tias tus naj npawb ntawm tshav kub stamped rau ntawm lub cev haum haum rau daim ntawv ntsuam xyuas zeb.
Kev sib tw siab:Xyuas kom cov chav kawm 3000 lub kaus mom yog ua ke nrog cov qauv hnyav- cov kav dej phab ntsa, thiab Chav Kawm 6000 lub kaus mom raug txwv rau siab - cov kab siab.
Kev tshuaj xyuas qhov muag:Xyuas kom tseeb tias lub qhov (socket) bore yog dawb los ntawm burrs, hlau shavings, los yog ovality uas yuav thaiv cov yeeb nkab ntxig.
NDT Requirements:Lub qhov (socket) welds feem ntau raug tshuaj xyuas sivLiquid Penetrant Testing (PT)los yogSib Nqus Particle Test (MT)tom qab vuam, raws li volumetric NDT zoo li Radiography (RT) yog ib qho nyuaj rau kev teeb tsa lub qhov (socket).
