ASTM A105 Flange

ASTM A105 flanges yog forged carbon steel flanges rau ambient- thiab siab dua-kub kev pab cuam nyob rau hauv lub siab. Cov flanges no tuaj yeem tsim tau raws li ntau yam kev qhia tshwj xeeb uas suav nrog ASME B16.5, ASME B16.47, ASME B16.48, ASME B16.36, MSS SP 44, API 605, thiab API 6A, thiab lwm yam. ASTM A105 cov khoom raug txwv qhov hnyav tshaj plaws ntawm 4540 kg.

A105 khoom:

• ASME B16.5, qhov ntau thiab tsawg: 1/2 "~ 24", Chav Kawm 150 txog Chav Kawm 2500, FF / RF / RTJ.
• ASME B16.47, qhov ntau thiab tsawg: 26 "~ 60", Chav Kawm 75 txog Chav Kawm 900, FF / RF / RTJ.
• API 6A Hom 6B thiab Hom 6BX, 2000 ~ 20000 psi, RTJ.
• Tailor-made flanges mus txog 72 "nrog thickness mus txog 300 hli.
• Flange hom: W / N, S / O, BL, Threaded, SW, Lap Joint, LWN, Phaj, Kab Blank.

ASTM A105 flanges yuav tsum tau tsim ua ib thooj los ntawm cov txheej txheem kub-forging. Cov txheej txheem kub-forging no, yog tuag forging los yog qhib-tuag forging, yog compressive kub-ua haujlwm. Cov hlau ntws nyob rau hauv cov kev taw qhia tsim thaum lub sij hawm yas deformation los tsim ib tug disc zoo li cov khoom uas nyob ze rau lub tiav flange. Cov txheej txheem forging kuj sib sau ua ke cov khoom siv los tsim cov qauv hlau tseem ceeb. Cov khoom yog tom qab machined rau lub caij nyoog zoo thiab qhov loj ntawm tiav flange.

Cov txheej txheem forging ntawm ASTM A105 vuam caj dab flanges.

Cov forged carbon steel ua raws li ASTM A105 yog pawg 1.1 cov khoom siv raws li ASME B16.5. Feem ntau, kev kho cua sov rau A105 flanges hauv Class 150 thiab Class 300 tsis tas yuav tsum tau ua. Rau flanges saum Class 300 los yog lwm yam teev los ntawm cov neeg siv kawg, kev kho cua sov, xws li annealing, normalizing, los yog normalizing thiab tempering, los yog quenching thiab tempering, tej zaum yuav ua tau. Kev kho cua sov kom zoo yog feem ntau siv nyob rau hauv rooj plaub uas cov khoom yuav raug cim raws li "ASTM A105N".

* Cov lej ntawm Cu, Ni, Cr, Mo thiab V yuav tsum tsis pub tshaj 1.00%; Tus lej ntawm Cr thiab Mo yuav tsum tsis pub tshaj 0.32%.
* Cov pa roj carbon sib npaug CE {{{0}} C + Mn / 6 + ( Cr + Mo + V ) / 5 + ( Ni + Cu ) /15, yuav tsum tsis pub tshaj 0.45%.

* Kev ntsuas nruj thiab kev ntsuas hardness yuav tsum tau ua rau txhua qhov cua sov ntawm cov flanges as-forged.

Kev ntsuas kub-kub qhia qhov siab tshaj plaws tso cai ua haujlwm gage pressures ntawm qee qhov kub. Nws yog ib qho tseem ceeb tsim qauv hauv kev lag luam piping. Lub siab thiab kub yog qhia nyob rau hauv bar units thiab degrees Celsius, los yog psi units thiab degrees Fahrenheit feem. Qhov ntsuas kub-kub ntawm ASTM A105 flanges ua raws li ASME B16.5 thiab ASME B16.47 muaj npe nyob rau hauv Table 1-1, Table 1-2, Table 2-1, thiab Table {{ 10}} ib.

Kev ntsuas kub-kub rau ASTM A105 flanges hauv bar units thiab degree Celsius tau teev nyob rau hauv Table 1-1 thiab Table 1-2; Kev ntsuas kub-kub rau ASTM A105 flanges hauv psi units thiab degrees Fahrenheit tau teev nyob rau hauv Table 2-1 thiab Table 2-2. Tabulated qhov tseem ceeb ntawm Chav Kawm 75 txog Chav Kawm 900 muaj feem xyuam rau A105 flanges tsim raws li ASME B16.47. Tabulated qhov tseem ceeb ntawm Chav Kawm 150 txog Chav Kawm 2500 muaj feem xyuam rau A105 flanges tsim raws li ASME B16.5. Txawm hais tias tso cai, ASTM A105 flanges tsis pom zoo rau kev siv ntev dua 425 degree [800 degree F], txij li cov theem carbide ntawm cov hlau tuaj yeem hloov mus rau graphite hauv qhov xwm txheej no.

ASTM A105 yog tsim los nrog UNS tus lej ntawm K03504. Vuam P-ntaub thiab pab pawg-ntaus yog 1 thiab 2 raws. Nws qhov sib npaug ASTM lossis ASME yog ASTM A181 Chav Kawm 70. ASTM A105 flanges tuaj yeem siv rau cov kev pabcuam ntawm ASME Boiler thiab Pressure Vessel Codes, ASME B31.1 thiab ASME B31.3. Qhov siab tshaj plaws kev ntxhov siab, kev ntxhov siab yooj yim, thiab kev ntxhov siab tso cai ntawm ASTM A105 tau teev tseg hauv Cov Cai uas tau hais dhau los.
