Kauv yeeb nkab Hoobkas yuav tsum tau ua ua ntej cov neeg kho tshuab kev ua tau zoo xeem thiab flattening xeem, thiab flaring xeem, thiab ua kom tiav cov txheej txheem. Kauv steel yeeb nkab zoo soj ntsuam txoj kev yog raws li nram no:
1, Los ntawm lub ntsej muag ntawm nws, uas yog kev soj ntsuam pom. Kev kuaj pom ntawm cov pob qij txha welded yog ib txoj kev yooj yim tab sis dav siv txoj kev sim yog ib feem tseem ceeb ntawm kev soj ntsuam cov khoom, lub ntsiab tsis xws luag thiab deviations muaj nyob rau saum npoo ntawm weld loj. Feem ntau los ntawm qhov muag liab qab, nrog rau tus qauv qauv, ntsuas thiab ntsuas cov cuab yeej xws li lub iav magnifying. Yog hais tias lub weld nto defects, weld defects yuav muaj nyob rau hauv.

2, Txoj kev kuaj lub cev: txoj kev kuaj lub cev yog siv qee qhov kev ntsuam xyuas lub cev lossis kev sim. Los yog nyob rau hauv lub workpiece cov khoom tsis zoo tshuaj xyuas, thiab feem ntau yog siv NDT txoj kev. NDT ultrasonic qhov tsis pom kev, kuaj pom hluav taws xob, ntsuas kev nkag mus, kuaj sib nqus thiab lwm yam.

3, Kev ntsuas cov hlab ntsha siab: cov hlab ntsha siab, ntxiv rau kev ntsuas nruj, tab sis kuj yog qhov ntsuas lub zog. Muaj ntau qhov kev sim ntawm ob qhov kev sim hydraulic thiab cua siab. Lawv tuaj yeem raug sim hauv kev ua haujlwm hauv cov hlab ntsha siab thiab cov kav dej welds compactness. Hydrostatic siab ntsuas yog rhiab tshaj li qhov ntsuas ceev thiab, tib lub sij hawm tom qab cov khoom kuaj tsis txhob nkim kev kho dej, cov teeb meem dej rau cov khoom siv tshwj xeeb. Tab sis qhov kev pheej hmoo yog ntau dua li qhov kev sim siab ntsuas. Thaum kuaj, nws yuav tsum ua raws li kev ntsuas kev nyab xeeb tsim nyog los tiv thaiv kev sib tsoo thaum lub sijhawm kuaj.

4, Compact test: kua los yog roj cia nkoj welding, uas yog tsis ntom weld defects, xws li nkag mus rau hauv cov kab nrib pleb, pores, slag, tsis tiav nkag mus rau cov ntaub so ntswg xoob thiab lwm yam, yuav siv tau los mus nrhiav qhov ntom ntom. Compactness test method yog: kuaj kerosene, nqa dej kuaj, dej yuav kuaj.

5, Kev sim hydrostatic yuav tsum tau ua txhua lub yeeb nkab hydrostatic xeem yam tsis muaj qhov xau, ntsuas ntsuas ntsuas P = 2ST / D qhov twg S- hydrostatic test stress test Mpa, hydrostatic test stress test raws li cov qauv hlau sib txuas qhia qhov tsawg kawg nkaus ntawm cov khoom tawm ( Q235 yog 235Mpa) 60% ntawm kev xaiv. Regulators lub sij hawm: D <508 xeem siab tuav lub sij hawm tsawg tshaj li 5 vib nas this; D≥508 kev ntsuas siab tuav lub sijhawm tsawg dua 10 vib nas this 4, tsis muaj kev puas tsuaj ntawm cov hlau vuam seam, sawb kawg weld thiab cov pob qij txha ncig yuav tsum X-ray lossis kuaj xyuas ultrasonic. Rau cov khoom siv hluav taws xob zoo tib yam thauj kauv hlau rau vuam yuav tsum yog 100% SX-ray lossis ultrasound xeem, siv rau hauv dej, dej phwj tuaj, cua, cua sov chav thiab lwm yam dej sib kis nrog kauv weld steel yeeb nkab yuav tsum yog X-ray lossis kuaj xyuas ultrasonic ( 20%).

Cov kauv steel yeeb nkab zoo kuaj tau, kauv yeeb nkab feem ntau muab faib ua peb pawg: Tsim nyog, rework thiab seem. Kev tsim nyog txhais tau hais tias qhov zoo thiab qhov zoo ntawm qhov zoo ntawm qhov ua tau raws li cov qauv lossis kev xa khoom thiab kev lees txais cov khoom siv kauv steel yeeb nkab; rework yog hais txog qhov zoo thiab cov tsos ntawm qhov zoo ntawm lub cev tsis ua raws li cov qauv kev lees paub thiab lub cev lub cev, tab sis tso cai rau kev kho tom qab kho tuaj yeem ua tau raws li cov qauv thiab kev lees paub ntawm cov kav dej; pov tseg yog hais txog qhov tsis zoo thiab cov tsos ntawm qhov zoo ntawm cov kauv hlau tseem tsis tau raws li tus qauv thiab kev lees paub tsis pub kho lossis rov ua dua tom qab.
