Simbi pombi igomba refu tambo yesimbi, iyo inoshandiswa zvakanyanya sepombi yekutakura zvinwiwa, zvakaita semafuta, gasi rechisikigo, mvura, gasi, chiutsi, nezvimwewo. Pamusoro pezvo, inoreruka pakurema kana ichikotama uye simba rekutenderera. zvakafanana, saka rinoshandiswawo zvakanyanya Kushandiswa mukugadzira zvikamu zvemakanika uye zvimiro zveinjiniya.Inoshandiswawo kugadzira zvombo zvakajairwa zvakasiyana-siyana, mbiya, mateko, etc. Mapombi esimbi akasungwa, anozivikanwawo sepombi dzakasungwa, ndedzepombi dzesimbi dzakasona, dzinova pombi dzesimbi dzakagadzirwa nesimbi mahwendefa kana mitsetse mushure mekumomoterwa uye kukwenenzverwa, kazhinji ne. kureba kwemamita matanhatu.Iyo nzira yekugadzira welded simbi pombi iri nyore, kugadzirwa kwakanaka kwakakwira, kune akawanda marudzi uye zvakatemwa, uye mari mumidziyo idiki, asi simba rakawanda rakaderera pane iro resimbi isina musono pombi.
Welded simbi pombi classification
Yakarongedzwa nenzira yekugadzira
(1) Zvinoenderana nemaitiro - arc welded pombi, kupikisa welded pombi (yakakwirira frequency, yakaderera frequency), gasi welded pombi, choto chemoto welded pombi.
(2) Maererano ne weld - straight seam welded pipe, spiral welded pipe
Yakarongedzwa nechikamu chechimiro
(1) Pombi dzesimbi dzakapfava dzakapfava—pombi dzesimbi dzakatenderera, pombi dzesimbi dzemativi mana, pombi dzesimbi dzakatenderera, pombi dzesimbi dzine mativi matatu, pombi dzesimbi dzine hexagonal, pombi dzesimbi dzerhombus, pombi dzesimbi dzine octagonal, masemicircular simbi madenderedzwa, mamwe.
(2) Mapaipi esimbi akaomesesa - ane hexagonal simbi pombi, shanu-petal plum-shaped simbi pombi, kaviri-convex simbi pombi, kaviri-convex simbi pombi, mavise simbi mapaipi, conical simbi pombi, marata mapaipi; kesi simbi mapaipi, etc.
Zvinoenderana nehupamhi hwemadziro, inogona kukamurwa kuita: mutete-walled simbi pombi uye gobvu-yakavezwa simbi pombi;
Zvinoenderana nechimiro chemagumo, inogona kukamurwa kuita: denderedzwa yakashongedzwa pombi uye yakakosha-yakaumbwa (square, flat, etc.) welded pombi;
Kuronga maererano nechinangwa
General welded pombi, galvanized welded pipe, oxygen-blown welded pipe, wire casing, metric welded pipe, idler pipe, deep well pombi pombi, pombi yemota, transformer pombi, yemagetsi welded thin-walled pombi, yemagetsi welded special-shaped pipe, scaffold pombi uye spiral welded pipe.
Chinangwa chikuru
Inoshandiswa zvakanyanya muinjiniya yekugovera mvura, indasitiri yepetrochemical, indasitiri yemakemikari, indasitiri yemagetsi emagetsi, kudiridza kwekurima, uye kuvaka maguta.Icho chimwe chemakumi maviri ezvigadzirwa zvakakosha zvakagadziriswa nenyika yedu.
Inoshandiswa pakufambisa kwemvura: kugovera mvura uye kudhonza.Zvekutakura gasi: gasi, chiutsi, liquefied petroleum gasi.
Nezvinangwa zvemaumbirwo: sepombi dzekututira, semabhiriji;mapaipi ezvitsuwa, migwagwa, zvivakwa zvekuvaka, nezvimwe.
Welded simbi mapaipi akakamurwa kuva galvanized uye asiri galvanized maererano pamusoro pakurapa pombi.Welded simbi mapaipi anogona kukamurwa kuva mhando mbiri pavanobva mufekitari: imwe yakarukwa pamagumo epombi, uye imwe yacho haina tambo pamagumo epombi.Pamapombi esimbi akasungwa ane shinda pamagumo epombi, kureba kwepombi imwe neimwe ndeye 4-9m, uye kune welded simbi mapaipi asina tambo, kureba kwepombi imwe neimwe ndeye 4-12m.
Mapaipi esimbi akaiswa akakamurwa kuita mapaipi esimbi akatetepa, akakora simbi pombi uye akajairwa simbi pombi zvichienderana nekukora kwemadziro epombi.Mapombi esimbi akajairwa ndiwo anonyanya kushandiswa mukugadzira pombi, uye bvunzo dzadzo ndeye 2.0MPa.Muedzo wekumanikidza wepombi yesimbi yakakora ndeye 3.0MPa.
Kune dzakawanda nzira dzekubatanidza dze welded simbi pombi, kusanganisira threaded connection, flange connection uye welding.Iyo flange yekubatanidza yakakamurwa kuita threaded flange yekubatanidza uye welding flange yekubatanidza, uye iyo welding nzira yakakamurwa kuita gasi welding uye arc welding.
Inowanzoshandiswa welded simbi pombi tsanangudzo siyana: nominal dhayamita 6 ~ 150mm
Welded simbi mapaipi anogona kuganhurwa zvakaganhurwa mumapoka matatu zvichienderana nekugadzira maitiro:
1. Magetsi kuramba welded simbi pombi
Magetsi anopikisa welded simbi pombi, Chirungu zita ERW (Electric resistance welded Pipe), weld mhando yakatwasuka musono.Iyo yekudzivirira welding inotora nzira yekumanikidza welding pasina filler simbi.Iko hakuna kuzadza kwezvimwe zvikamu mu weld seam.Chimiro cheganda uye kuswedera kwemaitiro e-high-frequency current inoita kuti mupendero weplate ubve uchipisa kune welding tembiricha, uye kuumbwa kunoumbwa nekusvina extrusion roller.Tissue welds.
Resistance welded simbi pombi inogona kupatsanurwa muzvikamu zviviri: high frequency kuramba welding HFW (High frequency welded pombi) uye yakaderera frequency kuramba welding LFW (Low frequency welding).
ERW simbi mapaipi anonyanya kushandiswa kutakura mhute uye mvura zvinhu zvakaita seoiri negasi rechisikigo, uye anogona kusangana nezvinodiwa zvakasiyana-siyana zvepamusoro uye zvakaderera.Parizvino, vane chinzvimbo chakakosha mumunda wepombi dzekufambisa munyika.
2. Spiral welded simbi pombi
Spiral welded simbi pombi, zita rechirungu SSAW (Spiral submerged-arc welding pipe), weld type is spiral seam.Iyo nzira yekunyudzwa kwearc welding inogamuchirwa, uye mukati nekunze mativi maviri akaiswa welded.Submerged arc welding (kusanganisira submerged arc surfacing and electroslag surfacing, etc.) inzira yakakosha yewelding, ine zvakanakira kugadzikana kwemhando yewelding, yakakwira welding kubereka, hapana mwenje wearc uye utsi hudiki neguruva.
Iyo spiral welded pombi ine dhayamita yakakura, inogona kusvika kupfuura 3000mm, uye inonyanya kukodzera kune yakakura-dhayamita pombi yekufambisa uye zvivakwa zvekuvaka.
Yetatu, yakatwasuka musono wakashongedzwa pombi yesimbi
Longitudinally Submerged Arc Welded Pipe, zita rechirungu rinonzi LSAW (Longitudinally Submerged Arc Welded Pipe), uye mhando yeweld yakatwasuka seam.Iyo nzira yekunyudzwa kwearc welding inoshandiswawo, uye mukati nekunze mativi maviri akaiswa welded.Ukobvu hwemadziro epombi yesimbi yakatwasuka yakakura, uye kushandiswa kwayo kwakafanana neiyo spiral welded steel pombi.
Zvinoenderana neakasiyana maitirwo ekugadzira, yakatwasuka musono welded simbi mapaipi anogona kukamurwa kuita mapoka maviri: UOE (Uing uye Oing kugadzira pombi) uye JCOE (J-ing, C-ing uye O-ing pombi).UOE yekugadzira nzira (U kugadzira, O kuumba, E kuwedzera dhayamita), JCOE yekugadzira nzira (simbi ndiro inotsikirirwa kuita J chimiro, yobva yatsindirwa muC chimiro uye O chimiro, uye yozowedzerwa).
Zvinofanira kucherechedzwa kuti submerged arc welding process (SAW) imhando yemagetsi fusion welding (EFW Electric Fusion Welded Pipe), iyo inosanganisa simbi nekudziisa simbi pakati peimwe kana akati wandei consumable electrodes uye workpiece.Imwe yemaitiro ayo iyo arc inonyungudutsa zvizere simbi uye yekuzadza zvinhu pasina kudzvanywa, uye iyo yekuzadza simbi chikamu chinobva kumagetsi.
