Nzira dzinonyanya kushandiswa pakugadzira mapaipi makuru-dhayamita anotakura zvinwiwa zvakaita segasi rechisikigo kana mafuta anosanganisira maviri-sided submerged arc welding (DSAW) uye longitudinal submerged arc welding (LSAW).
spiral weld
DSAW Simbi Pipe:
Longitudinal Welding
Longitudinal Welding
LSAW ndeimwe yemhando dzeDSAW.
DSAW idimikira rekuti "double-sided submerged arc welding," izwi rinosimbisa kushandiswa kwehunyanzvi uhu.
LSAW inomirira "Longitudinal Submerged Arc Welding," nzira inoratidzirwa nemawelds anowedzera kureba kwepombi.
Zvakakosha kuziva kuti DSAW inosanganisira zvose SSAW (Spiral Submerged Arc Welding) uye LSAW marudzi epombi.
Kuongorora kufanana uye kusiyana pakati peDASW neLSAW chaizvoizvo kunyanya kuenzanisa pakati peSSAW neLSAW.

Welding Technology
DSAW neLSAW dzinoshandisa nzira mbiri-sided submerged arc welding (SAW), apo welding inoitwa panguva imwe chete kumativi ose esimbi kuvandudza kunaka uye kupinda mukati meweld.
Applications
Inoshandiswa zvakanyanya mumamiriro ezvinhu apo kusimba kwakakwirira uye hombe dhayamita simbi mapaipi anodiwa, akadai semafuta uye gasi mapaipi.
Weld Seam Kuonekwa
Pane musono wakatanhamara weld mukati nekunze kwepombi yesimbi.
Kusiyana
Type ye weld
DSAW: Inogona kutwasuka (weld pamwe nekureba kwepombi) kana helical (weld yakaputirwa mufashoni yehelical kutenderedza muviri wepombi), zvichienderana nekushandiswa uye kutsanangurwa kwepombi.
LSAW: The weld musono anogona chete longitudinal, apo simbi ndiro inogadzirwa kuva chubhu uye welded pamwe kureba kwayo kureba.
Tarisa pane zvikumbiro zvepombi yesimbi
DSAW: Sezvo DSAW inogona kutwasanuka kana kutenderera, inonyanya kukodzera kune zvakasiyana-siyana zvekumanikidzwa kwakasiyana uye madhayamita, kunyanya kana mapaipi akareba kwazvo achidikanwa spiral DSAW inonyanya kukodzera.
LSAW: LSAW mapombi esimbi anonyanya kukodzera kune zvivakwa zvemudhorobha uye yakakwirira-kumanikidza kunyorera senge mvura uye gasi kutakura.
Pipe Performance
DSAW: Spiral welded pombi haina kuita kwakafanana neLSAW maererano nekushushikana kushivirira.
LSAW: Nekuda kwekugadzira kwayo simbi ndiro ichishandisa JCOE uye mamwe maitiro ekuumba, iyo LSAW simbi pombi madziro inogona kumira zvakanyanya yunifomu mechanicha zvinhu.
Mutengo uye Kubudirira Kwekugadzira
DSAW: Kana DSAW pombi iri spiral welded kazhinji yakachipa uye nekukurumidza kugadzira uye inokodzera mapaipi akareba.
LSAW: Sight seam welding, nepo ichipa mhando yepamusoro, inodhura uye inononoka kugadzira uye inokodzera maapplication ane zvakanyanya kuomarara zvinodiwa.
Sarudzo yeDSAW kana LSAW inoenderana nezvinodiwa chaizvo zvepurojekiti, kusanganisira bhajeti, kumanikidzwa kwepombi kunofanirwa kumira, uye kuoma kwekugadzira nekuisa.Kunzwisisa izvi zvakakosha zvakafanana uye mutsauko zvinogona kubatsira kuita sarudzo yakakodzera kune imwe engineering application.
