Ua Txhua Qib 2 Groove Tag Nrho -Penetration Welds Xav Tau Internal NDT Inspection

Ua Txhua Qib 2 Groove Tag Nrho -Penetration Welds Xav Tau Internal NDT Inspection

Hauv steel qauv engineering, groove tag nrho -kev nkag welds yog dav siv nyob rau hauv load- bearing kev twb kev txuas, lub ntsiab structural pob qij txha thiab tseem ceeb quab yuam- hloov txoj hauj lwm. Ntau tus neeg siv khoom thiab pab pawg tsim kho feem ntau muaj kev tsis sib haum xeeb txog cov qauv tshuaj ntsuam xyuas zoo: txawm tias tag nrho Qib 2 tag nrho -kev nkag welds xav tau 100% sab hauv uas tsis yog- kev kuaj kev puas tsuaj. Raws li cov qauv tseem ceeb hauv teb chaws thiab thoob ntiaj teb steel qauv vuam kev lees paub, kab lus no tau piav qhia txog qhov yuav tsum tau ua hauv kev tshuaj xyuas, kev soj ntsuam kev faib ua feem thiab thaj tsam zoo ntawm Qib 2 groove tag nrho -kev nkag welds, tsim cov qauv kev tswj hwm zoo rau qhov kev lees paub thiab xa khoom.

1. Cov ntsiab lus tseem ceeb ntawm Qib 2 Tag Nrho -Penetration Weld

Tag nrho -kev nkag groove weld yog hais txog daim ntawv weld uas nkag mus rau hauv lub hauv paus hlau tuab los ntawm kev ua groove thiab cov txheej txheem vuam tshuab. Nws muaj peev xwm muaj peev xwm ua tau zoo, kev hloov pauv kev ntxhov siab thiab muaj kev nyab xeeb ntawm cov qauv, thiab feem ntau yog siv rau cov khoom tseem ceeb ntawm cov khoom thauj -cov kabmob.

Qib 2 weld yog qhov feem ntau siv cov qib zoo hauv engineering, uas yuav tsum tau tsim cov qauv tsim nyog, tsis muaj teeb meem ntawm qhov chaw, thiab yuav tsum tau kuaj xyuas qhov tsis zoo. Sib txawv ntawm Qib 1 welds nrog tus qauv siab tshaj plaws thiab Qib 3 zoo tib yam welds, Qib 2 tag nrho -kev nkag welds muaj qhov tseeb thiab qauv NDT kev siv cov cai hauv kev lees paub kev lag luam.

2. Standard NDT Requirements rau Qib 2 Tag Nrho -Penetration Welds

Xaus: Qib 2 zawj puv -kev nkag welds yuav tsum tau kuaj xyuas NDT sab hauv, tab sis tsis tas yuav tsum tau 100% tag nrho- ntev nrhiav tau.

Raws li GB 50205-2020 Code rau Kev lees txais Kev Tsim Kho Zoo ntawm Cov Hlau Hlau thiab GB 50661-2011 Code rau Vuam ntawm Cov Qauv Hlau, txhua tus tsim kev nkag mus rau Qib 1 thiab Qib 2 welds yuav tsum ua tiav qhov kev ntsuas sab hauv tsis muaj kev puas tsuaj, uas txhais tau tiastsuas yog kev soj ntsuam pom tsis tau.

Qhov kev soj ntsuam tshwj xeeb yog ua raws li hauv qab no:

• Hoobkas prefabricated welds
Kev tshuaj xyuas sab hauv yuav tsum tau ua ntawm qhov piv txwv ntawm tsis pub tsawg tshaj 20% ntawm tag nrho cov vuam ntev. Qhov kev tshuaj xyuas ib leeg yuav tsum tsis pub tsawg tshaj 200mm. Yog tias tag nrho cov vuam ntev tsawg dua 200mm, tag nrho - ntev yuav tsum tau soj ntsuam.

• Ntawm -site installation welds
Sampling yuav tsum tau ua los ntawm tus naj npawb ntawm welds nyob rau hauv tib lub vuam tej yam kev mob, tsis muaj tsawg tshaj li 3 welds rau txhua batch ntawm tib hom.

• Kev tshuaj xyuas thiab qib kev tsim nyog
Ultrasonic Testing (UT) tau txais kev pom zoo rau kev kuaj pom sab hauv, ua raws li B- qib kev soj ntsuam tus qauv, thiab kev ntsuam xyuas sab hauv tsis zoo raws li qib 2 kev lees paub. Kev kuaj hluav taws xob hluav taws xob (RT) tuaj yeem siv rau kev kuaj xyuas thiab kuaj xyuas thaum tsim nyog.

3. Qhov txawv ntawm Qib 1 thiab Qib 2 Tag Nrho -Penetration Welds

Hauv kev tswj xyuas kom zoo, ob qib sib txawv nruj me ntsis kom tsis txhob dhau - kev tshuaj xyuas lossis kev tshuaj xyuas tsis zoo:

• Qib 1 puv -kev nkag welds
100% tag nrho -ntev ntev NDT yog qhov yuav tsum tau ua, nrog xoom kam rau ua qhov cuam tshuam tseem ceeb hauv lub cev, muaj feem xyuam rau cov khoom tseem ceeb heev -cov kabmob cov qauv thiab cov khoom qaug zog.

• Qib 2 puv -kev nkag welds
20% kev soj ntsuam piv txwv yog tau txais yuav, uas ua tau raws li engineering kev ruaj ntseg redundancy thiab kev lag luam rationality, thiab yog tus qauv tseem ceeb rau cov qauv tseem ceeb ntawm cov khoom siv welds.

4. Cov xwm txheej tshwj xeeb xav tau 100% Kev Tshuaj Xyuas Tag Nrho rau Qib 2 Welds

Raws li cov xwm txheej zoo sib xws, Qib 2 welds tsis tas yuav kuaj tag nrho, tab sis 100% tag nrho -ntev NDT yuav tsum tau ua raws li cov xwm txheej hauv qab no:

1. Daim duab kos duab qhia meej meej 100% tsis yog-kev kuaj kev puas tsuaj rau ib feem lossis tag nrho Qib 2 welds;

2. Welds siv rau cov khoom siv uas yuav tsum tau kuaj xyuas qaug zog thiab dynamic load ntev - lub sij hawm kev pab cuam;

3. Cov khoom tsis tsim nyog tau pom thaum lub sijhawm tshuaj ntsuam xyuas, thiab yuav tsum tau kuaj xyuas ob npaug; yog tias tsis tsim nyog dua, 100% kev tshuaj xyuas tag nrho ntawm cov khoom siv tib yam thiab tib hom yuav tsum tau ua;

4. Cov phiaj xwm tseem ceeb, cov txheej txheem tshwj xeeb thiab thib peb - tog saib xyuas yuav tsum tau kuaj xyuas tag nrho.

5. Kev tsis nkag siab ntau hauv On-Site Txais

Kev nkag siab yuam kev 1: Tag nrho tag nrho -kev nkag welds yuav tsum yog 100% tshuaj xyuas
Kev Kho: Kev nkag mus tag nrho yog qhov yuav tsum tau ua cov txheej txheem vuam, thaum 100% kev tshuaj xyuas tsuas yog yuav tsum tau ua rau Qib 1 welds. Qib 2 puv -kev nkag welds ua raws li 20% tus qauv qauv.

Kev nkag siab tsis meej 2: Qib 2 welds tsuas yog xav tau kev tshuaj xyuas qhov muag tsis muaj kev tshawb pom sab hauv
Kev Kho: Cov lus qhia meej qhia meej tias tag nrho - nkag mus rau Qib 1 thiab Qib 2 welds yuav tsum ua kom tiav NDT sab hauv. Kev tshuaj xyuas ib leeg tsis tuaj yeem ua tau raws li cov qauv kev lees paub kev nyab xeeb.

Kev nkag siab yuam kev 3: Groove daim ntawv txiav txim xyuas qhov kev faib ua feem
Kho: Tus qauv tshuaj xyuas yog txiav txim los ntawm tusweld zoo qib teev los ntawm kev tsim, tsis yog los ntawm daim ntawv zawj lossis daim ntawv nkag.

6. Kev Tswj Xyuas Zoo

Qib 2 groove puv -kev nkag welds yog cov khoom tseem ceeb ntawm steel qauv kev nyab xeeb. Standardized sampling Internal NDT tuaj yeem tshem tawm cov kev phom sij xws li cov kab nrib pleb sab hauv, tsis tiav fusion, slag inclusion thiab porosity, thiab xyuas kom meej tag nrho cov neeg kho tshuab kev ua tau zoo thiab kev ruaj ntseg ntawm cov pob qij txha.

Peb lub Hoobkas nruj me ntsis siv lub teb chaws thiab thoob ntiaj teb kev soj ntsuam vuam cov qauv, paub qhov sib txawv ntawm cov qib vuam thiab kev soj ntsuam xyuas kom raug, zam dhau - kev tshuaj xyuas thiab hauv qab - kev soj ntsuam kev pheej hmoo, thiab ua tiav kaw - lub voj voog kev tswj hwm zoo suav nrog kev tshuaj xyuas zoo li, qhov kev lees paub thiab sab hauv tsis yog {{3}.} Tag nrho cov ntaub ntawv vuam zoo tuaj yeem taug qab tau, ua tau raws li qhov kev lees paub thoob ntiaj teb thiab thib peb - tog yuav tsum tau soj ntsuam.
