Kukosha kweSawn uye Welded Pipe muInfrastructure Yemazuvano, Mukati meCangzhou, Hebei Province, panogara chigayo chesimbi chave chiri dombo repakona reindasitiri yepombi yesimbi kubva pakuvambwa kwayo muna 1993. Kambani iyi inobata 350,000 square metres, inozvikudza pfuma inosvika 680 miriyoni RMB, uye ine vashandi vakazvipira makumi matanhatu nemasere. Pakati pezvigadzirwa zvayo zvakawanda pane mapaipi akachekwa uye akaiswa welded, chinhu chakakosha chezvivakwa zvemazuva ano, kunyanya mukufambisa kwemvura yepasi.
Pasi pevhuSaw Welded Pipezvakakosha pakufambisa mvura nenzira kwayo uye yakavimbika munzvimbo dzakasiyana siyana. Ndivo vanoumba musana wezvivakwa zvedu zvemazuva ano, kuona kuti mvura yakachena inosvika mudzimba, mabhizinesi, nenzvimbo dzekurima. Kusarudzwa kwezvinhu zvepombi idzi kwakakosha, sezvo vachifanira kutsungirira kudzvinyirirwa kwenzvimbo yepasi pevhu vachichengetedza kuvimbika kwavo kwenguva refu. Imwe yesarudzo dzakakurumbira dzezvishandiso izvi ndeye spiral welded kabhoni simbi pombi, ine mukurumbira nekuda kwesimba rayo nekusimba kwayo.
S235 JR spiral simbi pombi uye X70 SSAW (Spiral Submerged Arc Welded) mutsetse pombi zvinhu zviviri zvakajairika zvinoshandiswa zvakanyanya mupasi pevhu pombi masisitimu. S235 JR pombi inocherechedzwa zvakanyanya nekuda kweakanakisa emakanika zvivakwa, ichiita kuti ive yakakodzera kune akasiyana maapplication, kusanganisira ekufambisa emvura. Kugona kwayo kuramba deformation pasi pekunetseka kunoita kuti inosangana nezvinodiwa zvepasi pevhu.
Nhasi, nekukurumidzirwa kwemaitiro ekukura kwemaguta, nzira yakavimbika yekufambisa mvura yepasi pevhu yave kiyi yekuvimbisa kurarama kwevanhu. Sekambani inotungamira muindasitiri yekugadzira simbi Pipe, chimwe chirimwa chesimbi muCangzhou City, Hebei Province, yanga ichipa mapombi eSaw Welded epamusoro-soro ezvivakwa zvepasi rose kubva payakavambwa muna 1993. Yayo S235 JR spiral simbi pombi uye X70 akanyudzwa arc welded spiral pombi, ane mapurojekiti adzo epasi pevhu, ane maprojekti epasi pevhu, ane mapurojekiti epasi pevhu akave ekugadzirisa zvinhu.
1. Kusimba kwepamusoro uye kusagadzikana kwekuora kunovimbisa kuchengetedzwa kwekufamba kwemvura kwenguva refu. S235 JR spiral pombi: Iyo inoratidzira yakanakisa kuramba kushushikana deformation uye yakakodzera kune yakaoma geological nharaunda, kuve nechokwadi chenguva refu yakagadzikana kushanda kwepombi. X70 SSAW pombi: Yakagadzirwa nesimbi yakakwirira-yakasimba uye yepamusoro spiral welding tekinoroji, inoshingirira-inoshingirira uye isingaore, yakakodzera kutapurirana kwemvura kureba uye nharaunda dzakaoma.
2. Tekinoroji yepamberi yakasanganiswa neyakaomesesa yemhando yekudzora inogadzira inogadzikana pombi system. Fekitori iyi inotora tekinoroji yakanyungudutswa arc welding (SAW) tekinoroji kuti iwane kugadzirwa kwakakura-dhayamita, machubhu akatetepa-akakomberedzwa, achinatsiridza kushandiswa kwezvinhu uku uchisimbisa simba. Mukubatana nechikwata chehunyanzvi chevanhu mazana matanhatu nemakumi masere uye mutsara wekugadzira wemazuva ano unokosha 680 miriyoni yeyuan, tinoona kuti pombi yega yega yesimbi inosangana nezviyero zvepasirese, zvichibatsira mukusimudzirwa kwenzvimbo dzakasvibira. Nekuvandudzwa kwezvido zvepasi rose zvekutonga zviwanikwa zvemvura, mapaipi akachekwa eCangzhou Steel Plant acharamba achipa mhinduro dzakasimba uye dzakachipa dzekufambisa kwemvura yemanisipala, yekurima neyemaindasitiri, kusimudzira kuvakwa kwezvivakwa zvekuchengetedza mvura.
pombi dzakachekwa-ne-welded dzinogadzirwa neCangzhou Steel Mills chikamu chakakosha chehurongwa hwemvura yepasi. S235 JR uye X70 spiral yakanyura arc welded pombi, iine yakanakisa mechaniki zvivakwa uye kuramba kune zvakatipoteredza zvinhu, zvakakosha pakuona kufambisa kwemvura kwakanaka. Tichitarisa kumberi, kukosha kwezvigadzirwa izvi kucharamba kuchikura, zvichiratidza kudiwa kweindasitiri yesimbi pombi yekugadzirwa kwemhando yepamusoro uye mhinduro itsva.
