Pombi yakakura-diameter longitudinally welded ishoko rinozivikanwa. Inogadzirwa nesimbi yesimbi. Mapombi akaiswa welded nehigh-frequency welding equipment anodaidzwa kuti longitudinally welded pipes. (Zita rakapihwa nekuti mawelds epombi yesimbi ari mumutsara wakatwasuka). Pakati pavo, maererano nezvinangwa zvakasiyana, kune zvakasiyana-siyana zvekugadzirwa kwemashure. (Yakakamurwa kuita scaffolding pombi, fluid pombi, waya casing, bracket pombi, guardrail pombi, nezvimwewo)

Kazhinji,mapaipi esimbi akatwasukaine dhayamita pamusoro pe325 inonzi hombe-diameter simbi mapaipi. Iyo welding process yehombe-dhayamita gobvu-yakavezwa longitudinal musono simbi pombi ine kaviri-sided yakanyura arc welding tekinoroji, uye manual welding inogonawo kuitwa mushure mekunge pombi yesimbi yagadzirwa. Iyo general inspection method ndeyekuona kukanganisa. Mushure mekuonekwa kwekukanganisa kwakakodzera, inogona kuendeswa. Zvigadzirwa zvepasi pasi zvinoda kuiswa weld zvakare. Mahombe-dhayamita akakora-akatarwa seam simbi mapaipi anowanzo akakodzera kutakurwa kwemvura, tsigiro yezvimiro zvesimbi, uye murwi. Vanoshandiswa zvikuru petrochemical, kuvaka, mvura engineering, simba indasitiri, kudiridza zvokurima, mumaguta kuvaka, etc. The simbi pombi anofanira kukwanisa kutsungirira kumanikidzwa mukati, uye kuita 2.5Mpa kumanikidzwa bvunzo, uye kuichengeta pasina leakage nokuti. miniti imwe. Iyo nzira yeeddy ikozvino kuona kukanganisa inobvumirwa kutsiva iyo hydraulic test. Nzira dzekuumba dzinonyanya kusanganisira UOE, RBE, JCOE, nezvimwewo, pakati peiyo JCOE ine mwero wekushandisa wakakwira. Iyo pombi inopera inogona zvakare kurongedzerwa zvinoenderana nezvinodiwa nevatengi, inonziwo threaded uye isina kuverengerwa.

Iyo nzira yekugadzira yakakura dhayamita yakatwasuka seam simbi pombi:

Maitiro ekugadzira ehombe-dhayamita yakatwasuka seam simbi pombi anowanzo sanganisira nzira dzekugadzira dzakadai sekupisa kunopisa, kupisa coiling, uye kukanda. Mapaipi makuru-dhayamita gobvu-akavakirwa simbi mapombi anowanzo shandisa maviri-mativi akanyura arc welding maitiro ekugadzira. Zvigadzirwa zvakakotama, zvakasungirirwa, zvakasungirirwa mukati, uye zvinogadziriswa kunze. Welding, kutwasanudza, flat heading, uye mamwe maitiro anosangana nezvinodiwa zve petrochemical standards.

Iko kushandiswa kwehombe-dhayamita yakatwasuka seam simbi mapaipi inonyanya kushandiswa kunhengo dzinotsigira muviri, senge kukwirisa zambuko, subsea piling, uye kukwira-kukwira kwechivako.

Zvishandiso zvinoshandiswa kune hombe-dhayamita yakatwasuka seam simbi mapaipi anowanzo ari Q345B uye Q345C. Q345D inoshandiswawo munzvimbo dzine tembiricha yakaderera. Q345E hombe-dhayamita yakatwasuka seam simbi mapaipi anonyanya kushandiswa muhukuru-hukuru simbi kuvaka chimiro.
