Manufacturing Process yeASTM A252 LSAW Simbi Pipe:

Longitudinal Submerged-arc Welded (LSAW) Pipe inotora yakanyura arc welding tekinoroji, ichishandisa filler welding, particle protection flux yakavigwa arc.

LSAW ndicho chidimburidzo chechirungu chekunyudza arc yakasungwa yakatwasuka musono simbi pombi.Iyo nzira yekugadzira yakanyudzwa arc welded yakatwasuka seam simbi pombi inosanganisira JCOE yekugadzira tekinoroji, coil inogadzira yakanyura arc welding tekinoroji uye UOE yekugadzira tekinoroji.

Maitiro ekugadzira Longitudinal Submerged-arc Welded(LSAW) Pipe ndeaya anotevera:

Ultrasonic plate probing → edge milling → pre-bending → kuumba → Pre-welding → Internal welding→ External welding → Ultrasonic kuongorora → X-ray kuongorora → Kuwedzera → hydraulic test →l.Chamfering → Ultrasonic kuongorora → X-ray kuongorora → magineti particle kuongorora pachubhu kupera

Mushonga weKemikari:

Simbi haifaniri kunge iine 0.050% phosphorous.

Hydrostatic Testing

Mechanical Testing

Bending Test-hurefu hwakakwana hwepombi huchamira ichitonhorwa ne90° kutenderedza cylindrical mandrel.

Kudzika bvunzo-kunyangwe kuyedzwa kusiri kudikanwa, pombi ichave inokwanisa kuzadzisa zvinodikanwa zvekuyedza.

Hydrostatic test-kunze kwekunge zvichitenderwa, hurefu hwega hwega hwepombi huchaiswa kune hydro-static bvunzo pasina kuvuza kuburikidza nemudhuri wepombi.

Nondestructive electric test-seimwe nzira kune iyo hydro-static bvunzo, muviri uzere wepombi yega yega uchayedzwa neinoparadza yemagetsi bvunzo.uko kunoitwa bvunzo dzemagetsi dzisingakonzereki, kureba kuchaiswa mabhii”NDE”

Kushandiswa kweASTM A252 LSAW Simbi Pipe:

Pombi yakarongedzerwa pasi peichi chirevo ndeyemapaipi epombi umo silinda yesimbi inoshanda senhengo yekusingaperi inotakura-mutoro, kana segoko rekugadzira akakanda-mu-nzvimbo makongiri mirwi.

Kushivirira kwedhayamita yekunze, ukobvu hwemadziro, kureba uye uremu:

Kunze Diameter	Iyo dhayamita yekunze yemapombi epombi haizosiyane kupfuura ± 1% kubva kune yakataurwa kunze kwedhayamita.
Kukora kwemadziro	Ukobvu hwemadziro panguva ipi neipi haufanirwe kupfuura 12.5% pasi peiyo yakatsanangurwa zita remadziro ukobvu.
Urefu	Mirwi yepombi ichapihwa mune imwe chete isina hurefu hurefu, hurefu hwakapetwa kaviri, kana muhurefu hwakafanana sezvakatsanangurwa muhurongwa hwekutenga, zvinoenderana nemiganhu inotevera:	Single random urefu	16 kusvika 25ft (4.88 kusvika 7.62mm), inch
