Spiral Welded Steel Pipes Manufacturing Process
Kusarudzwa kwezvinhu:
Simbi Coils: Yemhando yepamusoro macoil esimbi anosarudzwa, anowanzo gadzirwa kubva pasi-kabhoni kana yepakati-kabhoni simbi, kusangana neinodiwa michina zvivakwa uye kuumbwa kwemakemikari.
Kusunungura uye kutsemura:
Uncoiling: Makoiri esimbi anovhurwa uye anopepetwa kuita pepa fomu.
Slitting: Simbi yakatsetseka inochekwa kuita mitsetse yehupamhi hunodiwa. Upamhi hwemutsetse unosarudza dhayamita yepombi yekupedzisira.
Kuumba:
Spiral Formation: Mutsetse wesimbi unodyiswa kuburikidza nenhevedzano yema rollers ayo zvishoma nezvishoma anoiumba kuita spiral shape. Micheto yemutsetse inounzwa pamwe chete nehelical pateni kuti iite pombi.
Welding:
Submerged Arc Welding (SAW): The spiral seam yepombi inosungirirwa uchishandisa iyo yakadzika arc welding process. Izvi zvinosanganisira kushandiswa kwearc yemagetsi uye granular flux, iyo inopa yakasimba, yepamusoro-soro weld ine spatter shoma.
Weld Seam Inspection: Iyo weld seam inoongororwa hunhu uchishandisa isingaparadze nzira dzekuyedza dzakadai seye ultrasonic kana radiographic test.
Saizi uye Kuumbwa:
Sizing Mills: Iyo pombi yakashongedzwa inopfuura nepakati pezvigayo kuti iwane iyo dhayamita chaiyo uye kutenderera kunodiwa.
Kuwedzera: Hydraulic kana mechanical kuwedzera inogona kushandiswa kuve nechokwadi cheunifomu pombi zviyero uye kuwedzera zvinhu zvenyama.
Kuedza Kusina Kuparadza:
Ultrasonic Testing (UT): Inoshandiswa kuona kukanganisa kwemukati mune weld seam.
Hydrostatic Testing: Yese pombi inoiswa pasi pe hydrostatic pressure kuyedzwa kuti ive nechokwadi chekuti inokwanisa kubata madhiri ekushanda pasina kubuda.
Kupedzisa:
Beveling: Migumo yepombi yakakomberedzwa kuti igadzirire welding panzvimbo yekuisa.
Kurapa Kwepamusoro: Mapombi anogona kuwana marapirwo epamusoro senge kuchenesa, kupeta, kana kuita marara kuti awedzere kusaora.
Kuongorora uye Kudzora Hunhu:
Dimensional Inspection: Mapombi anotariswa kuti anoenderana nedhayamita, ukobvu hwemadziro, uye kureba kwakatemwa.
Mechanical Testing: Mapombi anoyedzwa kusimba kwekusimba, goho simba, kureba, uye kuoma kuti ave nechokwadi chekuti anosangana nezvinodiwa.
Kumaka uye Packaging:
Kumaka: Mapombi akanyorwa neruzivo rwakakosha senge zita remugadziri, pombi yakatarwa, giredhi, saizi, uye nhamba yekudziya yekutevera.
Packaging: Mapombi anounganidzwa uye akaputirwa zvinoenderana nezvinodiwa nevatengi, akagadzirira kutakurwa nekuiswa.
