2. Simba rakanakisa uye kuchinjika:

Iyo spiral chimiro cheSSAW pombi inowedzera simba rayo, ichiibvumira kurwisa kunze uye mukati mekumanikidza.Mapombi aya anokwanisa kumirisana nemamiriro ekunze emuchadenga, zvichiita kuti aenderane nepamusoro nepasi pevhu.Pamusoro pezvo, kuchinjika kwepombi dzeSSAW kunobvumira kuti igadziriswe nyore uye kuiswa munzvimbo dzakasiyana siyana, kusanganisira nzvimbo yakaoma uye ivhu risina kugadzikana.

3. Mutengo usingadhuri:

Kuenderera mberi welding maitirwo anowedzera kugadzirwa uku achidzikisa zvakanyanya hurema hwewelding uye mutengo.Pamusoro pezvo, spiral yakanyura arc welded pombi inopa simba repamusoro uye kusimba, inoderedza kugadzirisa nekugadzirisa mutengo pamusoro pehupenyu hwavo, zvichiita kuti ive sarudzo yehupfumi kuindasitiri.

Matambudziko akatarisana ne spiral akanyura arc welded pombi:

1. Kudzora kunaka:

Nekuda kweiyo yakaoma welding maitiro anosanganisirwa mukugadzira spiral yakanyura arc welded pombi, kuve nechokwadi chekuenderana mhando kunonetsa.Kana welding maparamendi asina kudzorwa nemazvo, kukanganisa kwewelding senge undercuts, pores, uye kushomeka kwefusion kuchaitika.Kuti ukunde dambudziko iri, matanho ekudzora emhando yepamusoro uye masisitimu epamusoro ekutarisa panguva yekugadzira akakosha.

2. Pipe dhayamita restriction range:

Nepo spiral undermerged arc welded mapombi akanakira madhiyayamita maapplications, anogona kunge asina kukodzera kumaindasitiri anoda madiki pombi saizi.Maitiro ekugadzira anoshanda zvakanyanya pamapaipi makuru edhayamita, zvichikonzera kuwanikwa kushoma kwemapurojekiti madiki akadai sepombi dzepombi dzekugara uye maindasitiri madiki ekushandisa.Nokuda kwezvinodiwa zvakadaro, dzimwe nzira dzekugadzira pombi dzinofanira kufungwa.

3. Surface coating:

Rimwe dambudziko rakatarisana neindasitiri yepombi yeSSAW kuve nechokwadi chekupfeka kwakakodzera uye kwakasimba kwepamusoro kudzivirira kubva mukuora uye kupfeka.Coating application pane inotenderera inoda midziyo yepamberi uye hunyanzvi kuti ive nechokwadi chekuvhara uye kunamatira.Kupfeka kwakakodzera kwepamusoro kwakakosha pakuwedzera hupenyu hwesevhisi yespiral yakanyura arc welded pombi, kunyanya munzvimbo dzakaoma.

Mukupedzisa:

Spiral undermerged arc welded pombi dzakaratidza kuve tekinoroji inobatsira zvakanyanya muindasitiri yemazuva ano, ichipa kugona, simba uye mutengo-kubudirira.Yayo yakasarudzika spiral weld seam inobvumira kugadzirwa kwakanaka uye kuwedzera kusimba, zvichiita kuti ive yakakodzera kune mapurojekiti makuru ekuvaka.Nekudaro, kuti urambe uchibudirira uye kupararira kugamuchirwa kweiyi tekinoroji yekugadzira, zvinonetsa zvakaita sekutonga kwemhando, mashoma dhayamita renji, uye machira epamusoro anofanirwa kugadziriswa.Nekukunda matambudziko aya kuburikidza nekufambira mberi kwetekinoroji uye kubatana kwemaindasitiri, spiral yakanyura arc welded pombi ine ramangwana rinovimbisa mukushandura nekuchengetedza zvakakosha zvivakwa pasirese.
