Cov lus nug nquag nug:
Nqe Lus Nug 1: Qhov txawv ntawm Hastelloy C276 thiab C22 flanges yog dab tsi?
Ob qho khoom siv - yog corrosion-resistant nickel alloys rau kev tsim cov forged flanges, sib txawv ntawm qhov sib piv ntawm cov khoom siv alloying. Alloy C276 (UNS N10276) muaj ntau ntawm molybdenum (15-17%) thiab tungsten (3-4.5%), uas txhim kho kev tiv thaiv nyob rau hauv kev txo qis ib puag ncig xws li hydrochloric acid thiab dilute sulfuric acid. Alloy C22 (UNS N06022) muaj cov ntsiab lus chromium ntxiv (20–22.5%), muab kev tiv thaiv siab rau oxidizing ib puag ncig, pitting thiab crevice corrosion hauv cov tshuaj chloride oxidizing. Rau kev ua haujlwm hauv cov txheej txheem oxidizing heev, C22 raug xaiv; rau siv nyob rau hauv ib puag ncig kho dua tshiab - C276.
Nqe Lus Nug 2: Cov hlau twg muaj cov khoom siv ntau dua: C276 lossis C22?
Raws li ASTM B575 Standard for Annealed Sheet thiab Board, qhov tsawg kawg nkaus tensile lub zog ntawm C276 yog siab dua (115 ksi / 790 MPa) tshaj C22 (100 ksi / 690 MPa). Rau ASTM B564 forged flanges, qhov tsawg kawg nkaus tensile lub zog rau ob qib yog 100 ksi (690 MPa), nrog C22 muaj ib tug me ntsis pov thawj zog (45 ksi / 310 MPa) piv rau C276 (41 ksi / 283 MPa). Kev xaiv ntawm cov khoom yuav tsum tsis txhob txiav txim siab los ntawm kev siv lub zog; Qhov tseem ceeb tshaj plaws yog qhov chaw ua haujlwm corrosive.
Nqe Lus Nug 3: C276 flanges puas tuaj yeem hloov nrog C22 flanges?
Kev hloov pauv tsis raug tso cai yam tsis tau kuaj xyuas ua ntej. C22 yog superior rau C276 nyob rau hauv cov nqe lus ntawm tsis kam mus rau oxidizing thiab chloride-muaj ib puag ncig, thiab kuj muaj zoo thermal stability. C276 tseem muaj txiaj ntsig zoo hauv cov cheeb tsam uas txo qis thiab hauv cov ntawv thov uas yuav tsum tau muaj zog ntxiv ntawm cov khoom siv annealed. Ua ntej hloov pauv, ua kom tiav cov txheej txheem dej chemistry, kev khiav hauj lwm kub, thiab cov cai tswj xyuas yuav tsum tau tshuaj xyuas.
