Kab lus no hais txog cov lus qhia tshwj xeeb thiab kev ntsuas ntawm ASME B16.5 Alloy 20 flanges.
Specifications ntawm Alloy 20 Flanges
Alloy 20 flangesfeature sib npaug ntawm 32-38% npib tsib xee, 19-21% chromium, 2-3% molybdenum, thiab 3-4% tooj liab, muab tshwj xeeb tsis kam rau pitting thiab crevice corrosion.
Alloy 20 flanges ua raws li ASME B16.5 rau qhov ntev, qhov siab, thiab kev ntsuas siab, nrog rau ASTM B462 rau forgings thiab ASTM B463 rau daim hlau. Kev ua raws li cov lus qhia tshwj xeeb no tau lees tias muaj kev sib koom tes nrog lwm cov kav dej, nrog rau cov khoom muaj xws li vuam caj dab, plam- ntawm, qhov (socket weld), threaded, ncej puab, thiab qhov muag tsis pom flanges hauv qhov ntau thiab tsawg NPS 1/2 txog 24.
ASME B16.5 Txheem Taw Qhia
ASME B16.5 tus qauv yog qhov tseeb tshwj xeeb rau cov yeeb nkab flanges thiab flanged fittings hauv North America thiab tau txais kev pom zoo thoob ntiaj teb. Rau Alloy 20 flanges, tus qauv no muab tag nrho cov qauv tsim qauv, tswj hwm:
Scope & Pressure Classes:Tus qauv npog flanges los ntawm NPS 1/2 "mus rau NPS 24" hauv cov chav kawm siab xws li Chav Kawm 150 txog Chav Kawm 2500.
Flange Hom:Nws txhais qhov ntev rau ntau hom flange, suav nrog Weld Neck (WN), Slip-On (SO), Socket Weld (SW), Threaded, Lap Joint, Dig Muag (BL), thiab lwm yam.
Critical Dimensions:ASME B16.5 mandates meej qhov ntev rau sab nraud txoj kab uas hla, ntsia liaj qhov rooj lub voj voog, tus naj npawb thiab qhov loj ntawm lub qhov ntsia hlau, flange thickness, thiab cov ntsiab lus ntawm lub ntsej muag.
Dimensional Tolerances:Tus qauv teeb tsa nruj nruj rau cov qhov ntev, suav nrog flange thickness (xws li, +3.0mm/-}0.0mm rau NPS Tsawg dua lossis sib npaug li 18), ntsia liaj qhov rooj qhov sib nrug, thiab lub ntsej muag perpendicularity los xyuas kom meej qhov sib txuas sib txuas.
Alloy 20 FlangeDimensions Raws li ASME B16.5
Dimensions for Alloy 20 flanges span NPS 1/2 to 24, with variations by type such as up face or ring -type joint for optimal sealing.

Alloy 20 Flanges Daim Ntawv Thov
Kev ua tshuaj lom neeg
Hauv cov nroj tsuag tshuaj, Alloy 20 flanges tuav sulfuric, phosphoric, thiab nitric acids, tiv thaiv kev xau thiab txuas lub neej ntawm cov cuab yeej siv. Lawv tsis kam mus rau chloride kev ntxhov siab tawg ua rau lawv qhov tseem ceeb rau cov reactors thiab cov kav dej, txo qis qis hauv kev ua haujlwm corrosive.
Kev lag luam kws tshuaj
Cov flanges no txhawb cov cheeb tsam tsis muaj menyuam nyob hauv kev tsim tshuaj, tiv thaiv cov tshuaj ntxuav thiab cov organic acids. Kev ua raws li cov qauv kev nyiam huv ua kom muaj kab mob sib kis -kev sib txuas dawb, txhim kho cov khoom huv huv thiab kev tswj hwm kev tswj hwm.
Khoom noj khoom haus thiab dej haus sector
Alloy 20 flanges yog siv rau hauv kev ua zaub mov los tuav cov khoom xyaw acidic xws li vinegar thiab citric acid yam tsis muaj kab mob. Lawv cov uas tsis yog -reactive nto tswj qhov tsw ncaj ncees thiab ua tau raws li FDA cov cai rau kev nyab xeeb, ruaj khov.
Kev ua haujlwm roj thiab roj
Nyob rau hauv offshore platforms, cov flanges no tiv taus roj qaub thiab dej hiav txwv corrosion, kom ruaj ntseg seals nyob rau hauv siab. Qhov no durability minimizes txij nkawm nyob rau hauv hnyav marine chaw, txhim kho kev nyab xeeb thiab ua hauj lwm efficiency.
Xaus
Alloy 20 flanges muab kev tiv thaiv tseem ceeb tiv thaiv sulfuric acid thiab chloride kev ntxhov siab corrosion tawg, tab sis lawv qhov kev ua tau zoo yog nyob ntawm qhov tseeb specification. Los ntawm nruj me ntsis ua raws li ASME B16.5 Cov Khoom Pab Pawg 3.1 kev ntsuam xyuas, koj xyuas kom meej tias koj lub cev tsis yog tshuaj lom neeg xwb tab sis kuj muaj suab nrov.
