Longitudinal Submerge-arc Welded pombi munguva pfupi pfupi yeLSAW pombi imhando yepombi yesimbi ine musono wekushivirira wakaenzana nepombi yesimbi, uye zvigadzirwa iplate resimbi, saka ukobvu hwemadziro epombi dzeLSAW hunogona kurema zvakanyanya semuenzaniso 50mm. , nepo dhayamita yekunze inogumira ku1420mm zvakanyanya.LSAW pombi ine mukana weiyo yakapfava yekugadzira maitiro, yakakwira kugadzirwa kwakanaka, mutengo wakaderera.
Kaviri Submerged Arc Welded (DSAW) pombi imhando yespiral welding seam simbi pombi yakagadzirwa nesimbi coil seyakagadzirwa zvinhu, kazhinji inodziya extrusion uye welded neatomatiki maviri-mativi akanyudzwa arc welding process.Saka kureba kamwe chete kwepombi yeDSAW kunogona kuita 40metres ukuwo kureba kwepombi yeLSAW kungoita 12 metres chete.Asi hurefu hwemadziro hwemapombi eDSAW hunogona kuita 25.4mm chete nekuda kwekuganhurwa kwemakoiri anopisa akakungurutswa.
Chinhu chakatanhamara chespiral simbi pombi ndechekuti dhayamita rekunze rinogona kuitwa rakakura kwazvo, Cangzhou Spiral Steel Pipes Group Co.ltd inogona kugadzira mapaipi makuru edhayamita ane dhayamita yekunze 3500mm zvakanyanya.Munguva yekugadzira, iyo coil yesimbi inoremara zvakaenzana, iyo yakasara kushushikana idiki, uye pamusoro haina kukweshwa.Iyo yakagadziriswa spiral simbi pombi ine kuchinjika kukuru muhukuru hwehupamhi hwedhayamita uye ukobvu hwemadziro, kunyanya mukugadzirwa kweyepamusoro-giredhi, hombe yemadziro gobvu pombi, uye dhayamita diki nehombe madziro mukobvu pombi, iyo ine mabhenefiti asingaenzaniswi pane mamwe maitiro.Inogona kusangana nezvimwe zvinodiwa zvevashandisi mune spiral simbi pombi yakatarwa.Iyo yepamusoro mbiri-mativi yakanyura arc welding process inogona kuona welding panzvimbo yakanakisa, izvo zvisiri nyore kuve nekuremara senge kusarongeka, welding kutsauka uye kusakwana kupinda mukati, uye zviri nyore kudzora kunaka kwewelding.Zvisinei, kana tichienzanisa nepombi yakatwasuka seam ine hurefu hwakafanana, kureba kweweld kunowedzera ne30 ~ 100%, uye kukurumidza kwekugadzira kwakaderera.
