Kubva kuma1930s, nekukurumidza kusimudzira kwemhando yepamusoro tambo inoenderera kugadzirwa uye kufambira mberi kwewelding uye yekuongorora tekinoroji, mhando yewelds yakaramba ichivandudzwa, uye akasiyana uye zvirevo zvemapombi esimbi akaiswa ari kuwedzera.Sona pombi yesimbi.Welded simbi pombi dzakakamurwa dzakatwasuka musono welded pombi uye spiral welded pombi maererano nechimiro welds.Kurongeka nenzira yekugadzira: process classification-arc welded pombi, kuramba welded pombi, (high frequency, low frequency) gasi welded pombi, choto chemoto welded.
Mapaipi madiki dhayamita akaiswa welded anosonerwa nemusono wakatwasuka, ukuwo hombe dhayamita dzakamonerwa pombi dzinowanzoita spiral weld.Maererano nechimiro chekuguma kwepombi yesimbi, yakakamurwa kuita denderedzwa yakashongedzwa pombi uye yakakosha-yakaumbwa (square, rectangular, etc.) welded pombi;maererano nezvinhu zvakasiyana-siyana uye mashandisirwo, inokamurwa kuita mvura yemugodhi Inotakura mapaipi esimbi akachekwa, mapaipi esimbi akakwenenzverwa kuti aenderere pasi-kumanikidzwa kwemvura, pombi dzemagetsi dzakashongedzwa nesimbi yebhandi conveyor rollers. , ronga nedhayamita rekunze * kukora kwemadziro kubva kudiki kusvika kuhombe.
Zvinowanzoshandiswa zvinhu welded pombi ndeiyi: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Nir18Nir1Cr18, etc.
Mapupu anoshandiswa papombi dzesimbi dzakashongedzwa mahwendefa esimbi kana simbi dzesimbi, dzakakamurwa kuita mapaipi akaiswa muchoto, mapombi emagetsi akaiswa (resistance welded) pombi uye otomatiki arc welded pombi nekuda kwemaitiro avo akasiyana emagetsi.Nekuda kweayo akasiyana mafomu ekushongedza, anogona kukamurwa kuva marudzi maviri:
yakatwasuka musono welded pombi uye spiral welded pombi.Nekuda kwechimiro chayo chekupedzisira, chakakamurwa kuita denderedzwa welded pombi uye yakakosha-yakaita (square, flat, etc.) welded pombi.Welded pombi dzakakamurwa kuva anotevera marudzi nekuda kwezvakasiyana zvinhu uye mashandisiro:
GB/T3091-2008 (Welded steel pipes for low pressure fluid transportation): Inonyanya kushandiswa kutakura mvura, gasi, mhepo, oiri, kudziyisa mvura kana chipfunga uye zvimwe zvinowanzodzikira mvura inodzika uye zvimwe zvinangwa.Iyo inomiririra zvinhu ndeye: Q235A giredhi simbi.
GB/T14291-2006 (Welded Steel Pipe for Mining Fluid Transport): Inonyanya kushandiswa kune yakatwasuka musono welded simbi mapaipi emugodhi wemhepo, dhiraivha, uye shaft yekuburitsa gasi.Mumiririri wayo zvinhu Q235A, Grade B simbi.
GB/T12770-2002 (Stainless steel welded simbi pombi yemakanika chimiro): Inonyanya kushandiswa kumichina, mota, mabhasikoro, fenicha, kushongedza kwehotera neresitorendi uye zvimwe zvikamu zvemakanika uye zvikamu zvechimiro.Zvishandiso zvayo zvinomiririra 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, nezvimwe.
GB/T12771-1991 (Stainless steel welded simbi pombi yekufambisa mvura): Inonyanya kushandiswa kutakura low-pressure corrosive media.Zvishandiso zvinomiririra 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, nezvimwe.
Uyezve, akakandwa Stainless simbi pombi nokuda kushongedzwa (GB/T 18705-2002), Stainless simbi welded nyere yokuvaka ukomba (JG/T 3030-1995), uye welded simbi nyere dzokupisa exchangers (YB4103-2000).
Longitudinal welded pombi ine yakapfava kugadzirwa maitiro, yakakwirira kugadzirwa kunyatsoshanda, yakaderera mutengo uye kukurumidza kusimudzira.Kusimba kwepombi dzakaiswa welded dzinowanzokwirira kupfuura dzepombi dzakaiswa seam dzakarukwa.A nhete isina chinhu inogona kushandiswa kugadzira pombi dzakasungwa dzine madhayamita epombi hombe, uye billet rine upamhi hwakafanana rinogona kushandiswawo kugadzira pombi dzakakandwa dzine madhayamita epombi akasiyana.Asi kana ichienzaniswa neiyo yakatwasuka seam pombi yehurefu hwakafanana, kureba kweweld kunowedzerwa ne30-100%, uye kukurumidza kwekugadzira kwakaderera.
Mapaipi mahombe ane dhayamita kana makobvu akakwenenzverwa anowanzo gadzirwa zvakananga kubva kusimbi, nepo mapaipi madiki akasungwa uye mapaipi matete-akaiswa madziro anongoda chete kubatanidza zvakananga kuburikidza nesimbi.Zvino mushure mekupenya kuri nyore, kudhirowa kwakanaka.
Wedzero: Iyo pombi yakasungwa yakasungwa nesimbi ye strip, saka haina kukwirira sepombi isina musono.
Zvigadzirwa zvinoshandiswa zvakanyanya muinjiniya yekugovera mvura, indasitiri yepetrochemical, indasitiri yemakemikari, indasitiri yemagetsi, kudiridza kwekurima, uye kuvaka kwemadhorobha.Ndechimwe chezvinhu makumi maviri zvakakosha zvakagadzirwa munyika yangu.
Inoshandiswa pakufambisa kwemvura: kugovera mvura uye kudhonza.Inoshandiswa kutakura gasi: marasha gasi, chiutsi, liquefied petroleum gasi.
Nekuda kwezvinangwa: semapombi ekuputira nemabhiriji;mapaipi emadhoko, migwagwa, uye zvivakwa zvekuvaka.
