Q: Lub hom phiaj ntawm Eddy Current Test (ECT) yog dab tsi?
A:ECT feem ntau yog siv los kuaj xyuas qhov chaw thiab nyob ze - cov kab nrib pleb, seams, thiab pits hauv cov uas tsis yog - ferromagnetic kav xws li stainless hlau (A312) thiab tsis yog - cov kav dej ferrous. Nws ceev thiab haum rau ntau lawm - kab tshuaj xyuas.
Q: Yuav ua li cas yog "Flattening Test"?
A:Ib lub nplhaib ntawm cov yeeb nkab yog flattened ntawm ob daim hlau mus rau ib qho kev ncua deb. Nws ntsuam xyuas cov ductility ntawm cov khoom thiab lub suab ntawm cov weld (rau welded kav) los yog homogeneity (rau seamless kav) los ntawm kev kuaj xyuas cov kab nrib pleb lossis tsis muaj fusion.
Q: "PMI" sawv cev rau dab tsi thiab vim li cas nws tseem ceeb?
A: Kev txheeb xyuas cov khoom zoo.Nws yog ib qho kev soj ntsuam spectroscopic (xws li, XRF phom) siv los txheeb xyuas cov tshuaj muaj pes tsawg leeg ntawm cov hlau alloy ntawm -site, kom ntseeg tau qib raug (xws li, qhov txawv ntawm 316 los ntawm 304) yog siv, uas yog ib qho tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm corrosion.
Q: Vim li cas cov kav dej seamless yuav tsum tau siv rau "Downhole" daim ntawv thov hauv Roj & Roj?
A:Downhole tubing, casing, thiab laum cov kav dej (API 5 CTCov qib zoo li J55, N80, P110) tiv taus qhov kub ntxhov, qhov chaw corrosive (H2S, CO2), thiab cov khoom siv tshuab. Kev tsim kho seamless muab qhov tsim nyog lub zog thiab kev ntseeg siab los tiv thaiv kev puas tsuaj loj.
Q: Dab tsi yog "Boiler Tube" thiab cov qib raug siv?
A:Boiler raj yog seamless raj siv hauv chav boilers, superheaters, thiab economizers. Cov qib uas muaj xws liASTM A179 Cov khoom lag luam(tsawg- carbon steel rau cov cua sov exchangers),A213 T11/T22/T91(alloy steels rau siab -kub seem), thiabA210(nruab nrab- carbon steel rau boiler thiab superheater raj).
