Spiral pombi fekitori inofanirwa kuitwa pamberi peye mechanika kuita bvunzo uye flattening bvunzo, uye flaring bvunzo, uye kuzadzisa zvakajairwa zvinodiwa. Spiral simbi pombi yekuongorora mhando nzira ndeiyi inotevera:
1, Kubva pamberi payo, ndiko kuongorora kwekuona. Kuongorora kwekuona kweakasungwa majoini inzira yakapusa asi inoshandiswa zvakanyanya nzira yekuyedza chikamu chakakosha chekuyedzwa kwechigadzirwa, kukanganisa kukuru uye kutsauka kunowanikwa pamusoro peiyo weld size. Kazhinji neziso rakashama, neyakajairwa modhi, geji uye maturusi ebvunzo segirazi rinokudza. Kana iyo weld surface yakaremara, weld defects panogona kunge paine mukati.

2, Nzira dzekuyedza dzemuviri: nzira yekuyedza yemuviri ndeye kushandisa imwe yemuviri zviitiko assay kana nzira yekuyedza. Kana mukati meiyo workpiece chirema chekuongorora, uye inowanzoshandiswa nzira dzeNDT. NDT ultrasonic chikanganiso chekuonekwa, kutariswa kwemwaranzi, kuyedza kupinda, kuyedza magineti uye zvichingodaro.

3, Kudzvanya midziyo simba bvunzo: kumanikidza midziyo, kuwedzera kune tightness bvunzo, asiwo simba bvunzo. Kune zvakajairika bvunzo yeaviri hydraulic bvunzo uye mhepo yekumanikidza. Ivo vanogona kuyedzwa mukushanda pasi pekumanikidza midziyo uye piping welds compactness. Hydrostatic pressure test inonyanya kunzwisiswa kupfuura yekumhanyisa bvunzo uye, panguva imwecheteyo mushure mekunge zvigadzirwa zvebvunzo zvisingatadzise kurapwa kwemvura, matambudziko emvura echigadzirwa anonyanya kushanda. Asi njodzi yakakura kudarika test pressure test. Kana ichiyedzwa, inofanirwa kuenderana neakakodzera matanho ekuchengetedza kudzivirira tsaona panguva yekuyedzwa.

4, Compact bvunzo: mvura kana gasi yekuchengetedza mudziyo welding, iyo isiri dense weld hurema, senge inopinda mukati mepakatsemuka, pores, slag, isina kukwana kupinda yakasununguka tishu uye nezvimwe, inogona kushandiswa kutsvaga density bvunzo. Compactness bvunzo nzira ndeidzi: parafini bvunzo, kutakura kuyedza mvura, mvura inoedza.

5, Iyo hydrostatic bvunzo inofanirwa kuitwa imwe neimwe pombi hydrostatic bvunzo isina kuvuza, kudzvanya bvunzo kudzvanya Calculate P = 2ST / D uko S- hydrostatic test stress test Mpa, hydrostatic test stress test zvinoenderana neinoenderana simbi chiyero inotsanangura iyo shoma dhigirii yegoho ( Q235 ndeye 235Mpa) 60% yesarudzo. Regulators nguva: D <508 test pressure inobata nguva isingasviki 5 seconds; D≥508 test pressure inobata nguva isingasviki 10 seconds 4, non-decete test of steel welding seam, strip end weld uye circumferential joints inofanira X-ray kana ultrasonic inspection. Kune zvakajairwa zvinopisa zvinwiwa zvekutakura spiral simbi kune weld inofanira kunge iri 100% SX-ray kana ultrasound bvunzo, inoshandiswa kumvura, tsvina, mhepo, kupisa chiutsi uye imwe yakajairika yekufambisa mvura ine spiral weld simbi pombi inofanirwa kunge iri X-rays kana ultrasonic inspection cheki ( 20%).

Iyo spiral simbi pombi yemhando yebvunzo mhinduro, spiral pombi inowanzo patsanurwa mumapoka matatu: Yakakodzera, rework uye zvimedu. Qualified zvinoreva hunhu uye chitarisiko chemukati memhando yekusangana nezviyero kana tekinoroji kuendesa uye kugamuchirwa mamiriro spiral simbi pombi; rework inoreva kunaka uye chitarisiko chemukati chemhando hachienderane zvizere nemaitiro ekugamuchirwa uye bhanhire muviri, asi bvumira kugadzirisa mushure mekugadzirisa kunogona kusangana nemazinga uye kugamuchirwa mamiriro spiral pombi; tsvina inoreva pasi pemhando uye chitarisiko chemukati wemhando ye spiral simbi ichiri isiri kusvika kune yakajairwa uye kugamuchirwa mamiriro haatenderi kugadzirisa kana kushandazve gare gare.
