Iyo yemhando yekuongorora nzira ye spiral pombi (saw) ndeiyi inotevera:

1. Kutonga kubva pamusoro, ndiko kuti, mukutarisa kwekuona.Kuongorora kwekuona kwemajoini akakwenenzverwa inzira yakapusa ine nzira dzakasiyana dzekuongorora uye chikamu chakakosha chekupedzwa kwechigadzirwa chekuongorora, kunyanya kutsvaga hurema hwewelding uye kutsauka kwechimiro.Kazhinji, inocherechedzwa nemeso asina kupfeka uye inoedzwa nemidziyo yakadai seyakajairwa modhi, geji uye magirazi ekukudza.Kana pane chikanganiso pamusoro pechiso che weld, panogona kunge paine chikanganiso mu weld.

2. Nzira dzekuongorora muviri: Nzira dzekuongorora muviri inzira dzinoshandisa zvimwe zviitiko zvemuviri pakuongorora kana kuongororwa.Kuongororwa kwekukanganisa kwemukati kwezvinhu kana zvikamu zvinowanzo tora nzira dzisiri dzekuparadza dzekuyedza.X-ray yekuona kukanganisa ndiyo nzira inonyanya kushandiswa yekusaparadza yekuyedza mapaipi espiral simbi.Hunhu hweiyi nzira yekuona ivavariro uye yakananga, chaiyo-nguva yekufungidzira nemichina yeX-ray, software yekuzvitongesa otomatiki kukanganisa, kutsvaga hurema, uye kuyera hurema.

3. Kuedza kwesimba kwemudziyo wekumanikidza: Mukuwedzera kune chisimbiso chekuvhara, mudziyo wekumanikidza unowanikwawo pasi pekuedzwa kwesimba.Kazhinji kune marudzi maviri e hydraulic test uye pneumatic test.Ivo vanokwanisa kuyedza weld density yemidziyo uye mapaipi anoshanda pasi pekumanikidzwa.Pneumatic kuyedzwa kwakanyanya uye nekukurumidza kupfuura hydraulic test, uye chigadzirwa chakayedzwa hachidi kudonhedzwa, kunyanya kune zvigadzirwa zvakaoma kudonha.Asi njodzi yekuongororwa yakakwira kupfuura hydraulic test.Panguva yekuyedzwa, kuchengetedzwa kwakafanana uye matanho ehunyanzvi anofanirwa kucherechedzwa kuitira kudzivirira tsaona panguva yekuyedzwa.

4. Muedzo weCompaction: Pamidziyo yakasungirirwa inochengeta mvura kana gasi, hapana hurema hwakaomeswa muweld, senge kuputika kwekupinda, pores, slag, kusamira uye yakasununguka sangano, nezvimwewo, izvo zvinogona kushandiswa kutsvaga compaction bvunzo.Densification bvunzo nzira ndeidzi: parafini bvunzo, bvunzo yemvura, bvunzo yemvura, nezvimwe.

5. Hydrostatic pressure test Yese pombi yesimbi inofanira kuiswa pasi pe hydrostatic test pasina kubuda.Kumanikidza kwekuyedza kunoenderana nekumanikidza kwekuyedza P = 2ST / D, uko iyo hydrostatic test pressure yeS Mpa, uye iyo hydrostatic test pressure inotarwa nemamiriro anoenderana.60% yezvakabuda zvakatsanangurwa muchimiro chechimiro.Kugadzirisa nguva: D <508 test pressure inochengetwa kwete pasi pe5 seconds;d ≥ 508 test pressure inochengetwa kwete pasi pemasekonzi gumi.

6. Kuedza kusingaparadzi kwemaitiro esimbi pombi welds, simbi musoro welds uye mhete dzemhete dzinofanira kuitwa neX-ray kana ultrasonic test.Kune simbi spiral welds inofambiswa nemvura inobvira yakajairika, 100% X-ray kana ultrasonic test ichaitwa.Spiral welds dzepombi dzesimbi dzinotakura zvinwiwa zvakajairika semvura, tsvina, mweya, kupisa chiutsi, nezvimwe zvinofanirwa kuongororwa neX-ray kana ultrasonic.Kubatsira kweX-ray yekuongorora ndeyekuti kufungidzira kune chinangwa, izvo zvinodiwa zvehunyanzvi hazvina kukwirira, uye iyo data inogona kuchengetwa uye kuteverwa.
