Precision yuav tsum tau ua loj flanges

Loj flanges yog siv los ua sealing thiab fastening pob qij txha, nrog rau kev yooj yim installation, rhiab orientation thiab ntev kev pab cuam lub neej. Lawv tau siv dav hauv cov nkoj loj hauv aerospace, roj av thiab tshuaj lom neeg kev lag luam. Ua ntej thiab qhov tseem ceeb, cov welds loj flange pob qij txha yuav tsum dhau 100 feem pua ​​​​ntawm ultrasonic lossis radiographic kuaj.

Cov tsos ntawm flange loj tsis tuaj yeem muaj cov kab nrib pleb lossis lwm yam tsis muaj zog hauv kev sib txuas ntawm flange lossis lub zog. Qhov ntev txoj kab uas hla loj flange, thaum lub siab ua hauj lwm yog sib npaug los yog ntau tshaj 0.8 lub sij hawm lub siab tshaj plaws tso cai ua hauj lwm siab teev nyob rau hauv specification.

Lub pob tw welds ntawm flanges loj thiab cov kav dej puag ncig yog raug rau 100 feem pua ​​​​x-ray tshuaj xyuas. Txoj kev tshuaj xyuas no yuav tsum tau ua raws li cov cai hauv JB4730. Ultrasonic tshuaj xyuas ntawm flanges loj yog qib I raws li cov khoom tsim nyog, thiab qhov yuav tsum tau muaj hluav taws xob yog qib II. Yog tias lub siab lub nkoj kos duab ntawm qhov chaw flange loj tsis tau raws li qhov yuav tsum tau ua rau kev tshuaj xyuas ntawm lub nkoj lub plhaub, nws yuav tsum tau ua raws li daim ntawv cog lus lossis kos npe hauv daim duab.

Kev sib txuas ntawm flange yog ib qho yooj yim siv thiab tuaj yeem tiv taus siab dua. Flange kev sib txuas yog dav siv nyob rau hauv industrial pipelines. Nyob rau hauv tsev, cov yeeb nkab txoj kab uas hla yog me me thiab lub siab yog tsawg, thiab flange kev twb kev txuas tsis pom. Yog tias koj nyob hauv chav boiler lossis chaw tsim khoom, muaj cov kav dej flange thiab cov khoom siv txhua qhov chaw.

Raws li cov hlau phaj vuam flanges, ntau cov neeg siv khoom nug seb qhov zoo ntawm cov hlau phaj vuam flanges zoo dua li ntawm forged vuam flanges. Qhov tseeb, qhov zoo ntawm hlau phaj welded flanges thiab forged welded flanges yog tib yam, tab sis qhov zoo ntawm hlau phaj welded flanges tsis tuaj yeem lav qhov twg, uas yog hais.

Yog vim li cas vim li cas cov khoom ntawm cov hlau phaj vuam flange yog qhov tsis zoo tshaj plaws yog tias nyob rau hauv cov txheej txheem dav dav, tsis muaj teeb meem nrog qhov ceev ntawm cov hlau phaj vuam flange, tab sis nyob rau hauv cov txheej txheem ntau lawm, qhov khoob ntawm cov hlau phaj vuam flange. tsis tshua pom. Yog li ntawd, Disqualified tom qab ntau lawm. Cov khoom siv ntawm kev sim hlau phaj vuam flange tsis tau lees paub.
