1) seamless steel yeeb nkab geometry kuaj

Seamless steel yeeb nkab txoj kab uas hla, phab ntsa thickness thiab curvature, ntev ntawm lub rooj soj ntsuam nrog ib tug caliper, micrometer, thiab khoov rau ko taw, qhov ntev ntawm daim kab xev yuav tsum tau xyuas.

Sab nraud txoj kab uas hla, phab ntsa tuab thiab ntev kuj tseem siv tau qhov ntsuas qhov ntsuas tsis siv neeg (xws li qhov tsis siv neeg txoj kab uas hla, tuab, ntsuas qhov ntev) hauv kev ntsuas tas li.Lub sijhawm lig xyoo 1980 ntawm lub xyoo pua 20th ntawm cov khoom siv seamless steel yeeb nkab ntau lawm yog feem ntau hauv internet tsis siv neeg txoj kab uas hla, thickness ntsuas ntaus ntawv, nyob rau hauv lub finishing cheeb tsam, ntev thiab hnyav khoom.OCTG seamless yeeb nkab xov tsis kuj yuav tsum tau kuaj xyuas.

(2) seamless steel raj, kev tshuaj xyuas sab nrauv

Visually tshawb xyuas sab hauv thiab sab nrauv feem ntau yog siv, qhov chaw ntxiv rau kev tshuaj xyuas Visual, ib qho kev cuam tshuam Prism kuj muaj rau kev tshuaj xyuas.Qee qhov tshwj xeeb lub hom phiaj seamless steel raj, kuj tau hu rau kev lees txais kev kuaj tsis muaj kev puas tsuaj, suav nrog Eddy tam sim no, sib nqus flux to, ultrasonic, sib nqus particle tshuaj xyuas ntawm steel nto zoo ntawm kev kuaj sab hauv thiab sab nraud.

(3) xyuas cov cuab yeej siv tshuab thiab thev naus laus zis

Txhawm rau txhawm rau txheeb xyuas cov khoom siv ntawm seamless steel yeeb nkab kom ua tau raws li cov qauv kev cai, xav tau cov cuab yeej cuab tam sim ntawm seamless steel raj sampling.

Kev ntsuas cov khoom siv tshuab suav nrog lub zog tensile, lub zog tawm los, elongation, cuam tshuam, thiab lwm yam. Flattening test rau kev ntsuas kev ua tau zoo suav nrog, flaring test, hydrostatic test, crimping test, bending test, perforation test.Cov khoom xeem no raws li cov qauv sib txawv thiab kev siv seamless thiab xaiv.

(4) kev sim tsis muaj kev puas tsuaj

NDT hais txog rooj plaub yam tsis muaj kev puas tsuaj rau seamless, coj lawv cov kev kuaj xyuas sab hauv thiab qhov chaw.Tam sim no, kev soj ntsuam sib nqus flux to, ultrasonic, Eddy tam sim no thiab fluorescent magnetic particle soj ntsuam, twb tau dav siv nyob rau hauv seamless steel hlab siv nyob rau hauv lub enterprise.Nondestructive test method tau tsim muaj txiaj ntsig zoo nyob rau xyoo tas los no, tsis ntev los no tau tshwm sim ib qho hologram, ultrasonic zaus spectrum tsom xam ntawm acoustic emission testing, ultrasonic imaging test, as well as high temperature ultrasonic testing and other new technologies.
