ERW pombi neLSAW pombi ese ari maviri akatwasuka seam welded pombi, ayo anonyanya kushandiswa pakufambisa mvura, kunyanya mapaipi akareba emafuta negasi. Musiyano mukuru pakati pezviviri ndeye welding process. Maitiro akasiyana anoita kuti pombi ive nehunhu hwakasiyana uye inokodzera akasiyana ekushandisa mamiriro.

Iyo ERW chubhu inoshandisa yakakwirira-frequency resistance welding uye inoshandisa inopisa-yakakungurutswa Broadband simbi makoiri semidziyo isina kubikwa. Seimwe yepombi dzinoshandiswa zvakanyanya nhasi, nekuda kwekushandiswa kwesimbi yakamonerwa mitsetse/makoiri ane yunifomu uye yakanyatso mativi ese semidziyo yakabikwa, ine mabhenefiti eiyo high dimensional kurongeka, yunifomu yemadziro ukobvu, uye yakanaka yemhando yepamusoro. Iyo pombi ine mabhenefiti epfupi weld seam uye yakanyanya kudzvanywa, asi maitiro aya anogona chete kugadzira madiki uye epakati-dhayamita matete-alled pombi (zvichienderana nehukuru hwesimbi tambo kana ndiro yesimbi inoshandiswa seyakagadzirwa). Musono we weld unowanzoita grey spots, unfused, grooves Corrosion defects. Nzvimbo dziri kushandiswa zvakanyanya igasi remumaguta uye crude oil product transportation.

Iyo LSAW pombi inotora yakanyura arc welding process, iyo inoshandisa imwechete yepakati-gobvu ndiro seyakagadzirwa, uye inoita mukati nekunze welding panzvimbo yewelding uye inowedzera dhayamita. Nekuda kwehupamhi hwezvigadzirwa zvakapedzwa uchishandisa mahwendefa esimbi semidziyo yakabikwa, ma welds ane kusimba kwakanaka, plastiki, kufanana uye compactness, uye ane mabhenefiti ehombe pombi dhayamita, pombi madziro ukobvu, kukwirira kupikisa, kushomeka kwekushisa uye kushomeka kwemarara. . Pakugadzira kusimba kwepamusoro-soro, kusimba kwepamusoro-soro, kwepamusoro-soro kureba kwemafuta uye gasi pombi, pombi zhinji dzesimbi dzinodiwa dzakakura-dhayamita dzakakobvu- dzakakomberedzwa dzakatwasuka-seam dzakanyura arc welded pombi. Zvinoenderana neyakajairwa API, mumapaipi makuru emafuta negasi, kana uchipfuura nemuKirasi 1 uye Kirasi 2 nzvimbo dzakadai senzvimbo dzealpine, nzvimbo dzegungwa, uye nzvimbo dzine vanhu vakawanda mumaguta, musono wakanyura wakanyudzwa arc welded pombi ndiyo chete yakasarudzwa rudzi rwepombi.
