Siab yeeb nkab weld zoo li qhov yuav tsum tau ua

Ua ntej siabcov kav dejua qhov kev ntsuam xyuas nondestructive, kev tshuaj xyuas qhov muag ntawm weld soj ntsuam kav yuav tsum ua tau raws li qhov yuav tsum tau ua.Cov kev cai dav dav rau cov yeeb nkab vuam zoo thiab qhov zoo ntawm cov pob qij txha welded yog raws li nram no: vuam yuav tsum saib zoo zoo, dav ntawm txhua sab ntug bevel overshadowed 2 hli tsim nyog.Fillet weld ceg ntev yuav tsum ua kom tau raws li cov qauv tsim, theem ntawm kev tswj hwm ntawm daim ntawv me me yuav tsum tau hloov pauv.

Welded sib koom nto tsis tso cai rau tawg, tsis muaj fusion, porosity, slag, spatter muaj nyob.Pipeline tsim kub yog qis dua -29 degrees, kiv cua kav ntawm hardened stainless hlau thiab alloy steel kav zoo li yuav loj weld nto, tsis muaj undercut.Cov yeeb nkab weld undercut lwm cov ntaub ntawv yuav tsum siab tshaj qhov tob ntawm 0.5mm, nruam undercut ntev yuav tsum tsis pub tshaj 100mm, thiab ob sab ntawm weld undercut loj hlob ntawm 10 feem pua ​​ntawm tag nrho cov weld ntev.Weld nto tsis tsawg tshaj li cov yeeb nkab nto.Weld reinforcement, Thiab tsis pub ntau tshaj 3 hli, (mus rau qhov siab tshaj plaws ntawm cov pob qij txha ntawm qhov zawj).Welded pob qij txha tsis ncaj ncees lawm phab ntsa thickness yuav tsum tsis pub tshaj 10% thiab tsis ntau tshaj 2 hli.

Nyob rau saum npoo ntawm kev sim tsis muaj kev puas tsuaj

NDT txoj kev xaiv txoj hauv kev: Cov yeeb nkab hlau nplaum yuav tsum tau siv hauv kev kuaj cov khoom sib nqus;non-ferromagnetic steel yuav tsum tau siv rau hauv kev ntsuam xyuas nkag.Nws muaj qhov xav tau ncua kev tawg ntawm cov pob qij txha welded, qhov saum npoo yuav tsum tsis muaj kev puas tsuaj rau kev ua kom txias tom qab vuam qee lub sijhawm;reheat cracking nyiam ntawm cov pob qij txha welded, qhov saum npoo yuav tsum nyob rau hauv kev sim tsis muaj kev puas tsuaj thiab tom qab vuam kev kho cua sov ib zaug.

Ray tshuaj xyuas thiab kuaj ultrasonic

Ray soj ntsuam thiab kuaj ultrasonic yog lub hom phiaj tseem ceeb ntawm lub pob tw pob qij txha thiab cov yeeb nkab fittings rau pob qij txha.NDT txoj kev xaiv los ntawm cov ntaub ntawv tsim.titanium, aluminium thiab aluminium alloy, tooj liab thiab tooj liab alloys, welded pob qij txha txhawm rau txheeb xyuas cov npib tsib xee thiab npib tsib xee alloys, thiab yuav tsum tau siv rau hauv kev tshawb nrhiav hluav taws xob.Muaj kev nyiam ncua kev sib tsoo tawg, nws txoj kev kuaj kab hluav taws xob thiab kuaj ultrasonic yuav tsum nyob rau qee lub sijhawm txias tom qab vuam.Thaum lub taub hau ntawm ib daim ntawv tais ceev tseg hauv lub casing muaj girth weld, lub weld yuav tsum tau khiav hauj lwm 100% ray detection, covert ua hauj lwm yuav ua tau tom qab dhau los ntawm kev ntsuam xyuas siab.Lub nplhaib txhawb nqa lossis cov kabmob phaj yog npog nrog cov pob qij txha welded yuav tsum yog 100% ntawm cov yeeb nkab-duab tshuaj ntsuam xyuas, tom qab dhau los tau them.Kev kuaj xyuas cov kev cai ntawm qhov nruab nrab seam vuam, kev kuaj tsis muaj kev puas tsuaj yuav tsum tau ua tom qab dhau qhov kev kuaj pom, kuaj hluav taws xob thiab kuaj ultrasonic yuav tsum tau ua tom qab qhov kev ntsuam xyuas tsis muaj kev puas tsuaj, qhov kev sim weld seam tuaj yeem txuas ntxiv tom qab kev ntsuam xyuas kev tsim nyog.
