Mukuvakwa kwepombi yegasi, kusarudzwa kwezvinhu uye nzira dzewelding zvakakosha kuti uve nechokwadi chekuchengetedza uye kushanda nesimba. SSAW (Spiral Submerged Arc Welded) pombi yesimbi ndechimwe chezvinhu zvinonyanya kushandiswa muindasitiri iyi. Mune ino blog post, isu tichaongorora kukosha kweakakodzera welding maitiro ekumisikidza gasi pombi pombi uchishandisa SSAW simbi pombi uye nekupa gwara rekutanga rekunzwisisa ichi chakakosha chikamu chekuvakwa kwepombi.
Chii chinonzi SSAW Steel Pipe?
SSAW simbi pombiinogadzirwa kubva kuspirally welded steel strips kuti ibudise yakasimba, inogara yakakura-dhayamita pombi. Rudzi urwu rwepombi inonyanya kufarirwa mumaindasitiri egasi nemafuta nekuda kwekupokana kwayo nekumanikidza kwakanyanya uye ngura. Maitiro ayo ekugadzira anoshandisa yakanyura arc welding, iyo inoburitsa yakachena uye yakasimba welds, ichiita kuti ive yakakodzera kune yakakosha maapplication akadai semapaipi egasi chaiwo.
Kukosha Kwemaitiro Akakodzera Welding
Welding inhanho yakakosha mukugadzirisa gasi pombi yekuisa, uye mhando yeweld inogona kukanganisa zvakanyanya kuperera kwepombi. Maitirwo akafanira emagetsi akakosha kuti ive nechokwadi chekuti SSAW simbi pombi majoini akasimba uye anodonhedza-kusabuda. Heano zvimwe zvinhu zvakakosha zvekufunga kana welding SSAW simbi pombi yemapombi egasi chaiwo:
1. Welding Technique: Sarudzo yekugadzira welding inokanganisa kunaka kweiyo weld. Zvichienderana nezvinodiwa zveprojekiti, maitiro akadai seTIG (Tungsten Inert Gas) kana MIG (Metal Inert Gas) anogona kushandiswa. Imwe neimwe nzira ine zvayakanakira nezvayakaipira, uye kusarudza nzira yakakodzera kwakakosha kuti uwane chisungo chakasimba.
2. Kugadzirira Kwezvinhu: Pamberi pekuputira, pamusoro peiyo spiral yakanyura arc welded steel pipe inofanira kugadzirirwa. Izvi zvinosanganisira kuchenesa pamusoro uye kubvisa chero tsvina inogona kuderedza weld, senge ngura, mafuta kana tsvina. Mukuwedzera, iyo pombi inoda kurongeka zvakanaka kuti ive nechokwadi chekuisa weld.
3. Welding parameters: Zvinhu zvakadai sewelding kumhanya, voltage uye ikozvino zvinofanirwa kunyatsodzorwa panguvasimbi pombi yewelding. Aya ma paramita anokanganisa kupisa kwekuisa uye kutonhora mwero, izvo zvinozokanganisa ma mechanic properties ye weld.
4. Post-weld inspection: Mushure mekuputika, kunyatsoongorora kunofanira kuitwa kuti uone chero kukanganisa kana kusimba kusina simba mu weld. Nzira dzisiri dzekuparadza dzekuyedza dzakadai seye ultrasonic bvunzo kana radiographic bvunzo dzinogona kushandiswa kuve nechokwadi chekuvimbika kweweld.
Kuzvipira Kwedu kune Hunhu
Iri muCangzhou, Hebei Province, kambani yanga iri mutungamiri muindasitiri yekugadzira pombi yesimbi kubvira 1993. Kambani iyi inobata nzvimbo inosvika 350,000 square metres, ine midziyo yeRMB 680 miriyoni, uye ine 680 nyanzvi nyanzvi dzakazvipira kugadzirwa kwemhando yepamusoro spiral akanyudzwa arc welded steel pombi. Ruzivo rwedu rwakapfuma uye michina yemhando yepamusoro inoita kuti tisangane nezvinoda kuomesesa zveindasitiri yemapombi egasi.
