Hastelloy B2yog npib tsib xee-molybdenum alloy muaj npe nrov rau nws qhov tshwj xeeb tiv thaiv kom tsis txhob muaj ib puag ncig. Tsis zoo li cov qauv stainless hlau, uas tso siab rau chromium rau oxidation kuj, Hastelloy B2 muab nws cov corrosion kuj los ntawm cov ntsiab lus siab molybdenum (kwv yees li 28%). Qhov no muaj pes tsawg leeg ua rau nws zoo tiv thaiv hydrochloric acid nyob rau hauv tag nrho cov concentrations thiab kub, nrog rau sulfuric, acetic, thiab phosphoric acids.
Peb lub Hoobkas xyuas kom meej tias tag nrho cov ntaub ntawv raw ua raws li ASTM B564 tus qauv rau nickel alloy forgings. Cov khoom siv kho tshuab raug rau kev daws teeb meem-annealed Hastelloy B2 suav nrog lub zog tensile ntawm 760 MPa (110 ksi), lub zog tawm ntawm 350 MPa (50 ksi), thiab elongation ntawm 40%.
ASME B16.5 Hastelloy B2 WN Flange Specification Table
ASME B16.5 cov lus qhia tshwj xeeb rau Weld Neck Flanges yog qhov siv tau los ua kom muaj kev sib hloov, siab ncaj ncees, thiab kev sib haum xeeb. Hauv qab no yog cov ncauj lus kom ntxaws ntxaws ntawm txhua qhov tseem ceeb thiab cov kab ke feem ntau nthuav tawm hauv cov rooj sib tham (qhov loj me pom hauv ntiv tes tshwj tsis yog sau tseg; metric sib npaug muab rau qhov pom tseeb).
1. Nominal Pipe Size (NPS)
Qhov sib txawv ntawm ½ mus rau 24 nyob rau hauv. Qhov no txhais tau hais tias cov yeeb nkab txoj kab uas hla sib txuam thiab ua kom lub flange bore dlhos nrog cov yeeb nkab teem caij raws li tus neeg yuav khoom.
2. Sab nraud txoj kab uas hla ntawm Flange (O / A)
The overall flange diameter. Critical for bolt circle alignment and equipment compatibility. Tolerances: ±1.6 mm (≤24 in) or ±3.2 mm (>24 ib.).
3. Thickness ntawm Flange (C / B / T)
Yam tsawg kawg nkaus flange thickness (tsis suav lub ntsej muag tsa rau cov chav kawm siab dua). Muab lub zog tsim nyog los tiv thaiv lub zog sab hauv thiab bolt loads. Rau Chav Kawm 150, thickness pib ntawm 0.38 rau NPS ½ thiab nce zuj zus.
4. Txoj kab uas hla ntawm tsa ntsej muag (R / G)
Tus qauv tsa- ntsej muag txoj kab uas hla ntawm ib chav kawm. Rau Chav Kawm 150 thiab 300: 1/16 hauv (1.6 mm) qhov siab; rau Chav Kawm 600 thiab siab dua: 1/4 hauv (6.4 mm) qhov siab. Xyuas kom zoo gasket compression thiab sealing.
5. Txoj kab uas hla ntawm Hub ntawm Base (X)
Qhov loj kawg ntawm tapered hub. Distributes dabtsi yog khoov stresses zoo.
6. Ntev dhau ntawm Hub (Y / H)
Zuag qhia tag nrho ntev los ntawm flange lub ntsej muag mus rau weld kawg. Nws yog ib qho tseem ceeb rau kev npaj weld thiab cov yeeb nkab sib dhos. Cov hubs ntev dua hauv cov chav kawm siab dua muab kev txhawb nqa ntxiv.
7. Nkoj (B1)
Sib npaug hauv txoj kab uas hla ntawm cov yeeb nkab txuas (tshwj xeeb los ntawm cov neeg yuav khoom raws li phab ntsa thickness / teem caij). Rau tus qauv bore, muaj nuj nqis; kev cai bores muaj.
8. Hub Diameter ntawm Vuam kawg
Kwv yees li qhov sib npaug ntawm cov yeeb nkab sab nraud txoj kab uas hla, nrog kev ua siab ntev ua kom muaj qhov zoo sib xws -up (+2.4 mm / –0.8 mm rau Tsawg dua lossis sib npaug rau 5 in; +4.0 mm / – 0.8 mm rau Ntau dua lossis sib npaug li 6 hauv).
9. Bolt Circle Diameter
Kev ncua deb hla tus ntsia liaj qhov rooj - qhov chaw. Txiav txim siab qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov sib txawv.
10. Number of Bolt Holes thiab Bolt Hole Diameter
Standardized rau txhua chav kawm thiab qhov loj (bolt qhov yog 1/8 nyob rau hauv loj tshaj bolt txoj kab uas hla). Xyuas kom tsis tu ncua load faib.
11. Fillet Radius (r)
Hloov lub vojvoog ntawm hub- mus rau - flange junction. Minimizes kev nyuaj siab concentration.
12. Vuam Neck Taper Paub meej
Lub hub tapers ntseeg nkaws los ntawm qhov kawg weld mus rau lub ntsej muag flange, muab qhov zoo tshaj plaws kev ntxhov siab faib.
Cov kev ntsuas no yog sib cuam tshuam. Piv txwv li, qhov ntev ntawm lub hub thiab taper ncaj qha cuam tshuam rau lub flange lub peev xwm los tswj lub sijhawm khoov, thaum lub voj voog lub voj voog thiab tus naj npawb ntawm lub qhov kom paub meej tias txawm tias lub gasket loading.
Txhua qhov loj me tau raug txheeb xyuas thaum lub sijhawm CNC machining nrog kev ua siab ntev nruj dua li ASME B16.5 yam tsawg kawg nkaus kom lav qhov zoo meej haum -up.

Siab dua - cov chav kawm siab (600, 900, 1500, 2500) ua raws li cov qauv qub uas muaj qhov sib npaug ntawm cov thickness, hub ntev, ntsia liaj qhov rooj vaj huam sib luag, thiab ntsia liaj qhov rooj loj los txhawb kev ntsuas siab.
Tag nrho cov rooj rau cov chav kawm no, suav nrog lub nplhaib - hom sib koom (RTJ) tig ntsej muag thiab txo flanges, muaj nyob rau ntawm kev thov.
Vim li casXaiv Jinie Alloy Flanges?
Kev ua raws li ASME B16.5 guarantees:
• Zero to thaum ua ke nrog cov gasket raug
• Qhov zoo tshaj plaws kev faib kev ntxhov siab los ntawm lub hub tapered
• Tag nrho kev sib raug zoo nrog cov kav dej uas twb muaj lawm thoob ntiaj teb
Txhua Hastelloy B2, Duplex UNS S32750, Inconel, lossis Monel WN flange peb muab yog tsim los ntawm forged billets, cua sov- kho, thiab tshuaj xyuas rau cov ntsiab lus tseeb, txhawb nqa los ntawm EN 10204 3.1/3.2 daim ntawv pov thawj.
Rau kev cai bore, tshwj xeeb kev ntsib, los yog loj -nqi nqi,tiv tauj peb pab neeg technicalnrog koj cov NPS, chav kawm, cov khoom siv, thiab cov sijhawm xav tau. Peb xa thoob ntiaj teb nrog lub sijhawm luv luv thiab tsis muaj kev cuam tshuam zoo.
