Kazhinji, tinodaidza mapaipi ane minwe ane dhayamita rekunze rakakura kupfuura 500mm kana kupfuura semapaipi esimbi akakura-dhayamita akatwasuka. Mahombe-diameter akatwasuka-seam simbi mapaipi ndiyo yakanakisa sarudzo yemapurojekiti makuru epombi, mapurojekiti ekufambisa mvura uye gasi, uye kuvaka pombi network. Mune mamwe mazwi, hombe-dhayamita yakatwasuka-seam simbi pombi ine madhayamita akakura uye zvidiki zvisingakwanisi (iyo yazvino dhayamita yepombi dzesimbi isina musono i1020mm, kureba kwepombi dzesimbi mbiri-weld dzinogona kusvika 2020mm, uye dhayamita yepamusoro yeimwe- weld seams inogona kusvika 1420mm), maitiro ari nyore uye mutengo wakaderera. uye zvimwe zvakanakira zvinoshandiswa zvakanyanya.
Kaviri-mativi akanyura arc akasungwa akatwasuka seam simbi mapaipi zvakare akatwasuka musono seam mapaipi. Iyo arc yakanyudzwa yakasungirirwa yakatwasuka musono simbi pombi inotora iyo JCOE inotonhora yekugadzira maitiro, welding seam inotora waya wewelding, uye yakanyudzwa arc welding inotora iyo particle flux. Iyo huru yekugadzira maitiro eiyo yakanyudzwa arc welded yakatwasuka seam simbi pombi inochinjika, uye inogona kuburitsa chero yakatarwa, iyo inonyanya kusangana nezvinodiwa nenyika dzepasi pombi yesimbi, nepo kugadzirwa kwepamusha kunowanzo tora yakakwira frequency yakatwasuka seam simbi pombi.
Nekuvandudzwa kwehupfumi hwenyika, kudiwa kwesimba kwakawedzera zvakanyanya. Mumakumi gumi kana makumi emakore anotevera, zvakakosha kuvandudza tekinoroji uye kuvaka chirongwa.
