Musiyano mukuru pakati pemapaipi maviri akashongedzwa epiral welded pombi uye yakatwasuka welded pombi ndiyo mutsauko mune welding fomu.

Spiral welded pipe is a low carbon carbon structural simbi kana yakaderera alloy structural simbi tambo yakakungurutswa muchubhu isina chinhu ine imwe helix angle (inonziwo forming angle), yobva yaiswa weld yoitwa pombi yakabatana, inogona kushandisa kamutsetse nhete. simbi Kugadzirwa hombe dhayamita simbi pombi.Spiral welded pombi inonyanya spiral undermerged arc welded pombi (SSAW), iyo inowanzoshandiswa mukuvaka mapaipi egasi akasiyana muChina.Zvinotsanangurwa zvaro zvinoratidzwa ne "kunze dhayamita * madziro ukobvu".Spiral welded pombi dzine divi rimwechete-welded uye kaviri-sided welded.Iyo welded pombi ichava nechokwadi chekuti hydraulic bvunzo uye kusimba kwesimba uye kutonhora kwekukotama kuita kweiyo weld kunoenderana nemirairo.

Iyo yakatwasuka seam welded pombi ndeye yakakwira-frequency ikozvino uye nhanho yekuswedera iyo inogadzirwa neiyo solder layer iyo welding isati yagadzirwa nemuchina wekuumba, uye mupendero wechubhu isina chinhu inodziya uye yakanyungudutswa, uye inosanganiswa. pasi peimwe simba rekumanikidza, kutonhora kuumba.Iyo yakakwirira-frequency yakatwasuka seam welded pombi inoshandiswa umo mupendero wepombi isina chinhu inonyungudutswa nepamusoro-frequency current (ERW), iyo inonzi yakatwasuka seam yakanyura arc welded pipe (LSAW) nekunyunguduka nemagetsi arc.

Kusimba kwe spiral welded pombi kunowanzo kukwirira kupfuura iyo yepombi yakatwasuka yakasungwa.Iyo huru yekugadzira maitiro ndeye yakadzika arc welding.The spiral welded pombi inogona kubudisa welded pombi ane siyana pombi madiyamita pamwe chete upamhi blank, uye anogonawo kubudisa welded nyere dzine madhayamita akakura ane nhete.

Iyo nzira yekugadzira yeyakatwasuka musono welded pombi iri nyore, kunyanya mukuita kwekugadzira, iyo yakakamurwa kuita yakakwirira-frequency welded yakatwasuka musono welded pombi uye yakanyura arc welded yakatwasuka welded pombi.Iyo yakatwasuka seam welded pombi ine yakakwirira kugadzirwa kwekuita, yakaderera mutengo uye nekukurumidza kusimudzira.

Zvisinei, kana ichienzaniswa nepombi yakatwasuka yakashongedzwa pombi yehurefu hwakafanana, kureba kweweld kunowedzerwa ne30 kusvika ku100, uye kukurumidza kwekugadzira kwakaderera.Naizvozvo, dhayamita diki welded pombi dzinonyanya kutwasanudza musono welded, nepo hombe dhayamita welded pombi dzinonyanya spiral welded.
