Welded pombi, inozivikanwawo seye welded simbi pombi, inogadzirwa nesimbi ndiro kana tambo yakashongedzwa mushure mekudhonzwa nekugadzira.Welded simbi pombi ine zvakanakira nyore kugadzirwa muitiro, yakakwirira kugadzirwa kunyatsoshanda, zvakawanda mhando uye nokurondedzerwa, uye kushoma midziyo mari, asi simba rayo rakaderera kupfuura musono simbi pombi.Kubva kuma1930s, nekukura nekukurumidza kwekugadzirwa kwemhando yepamusoro-soro uye kufambira mberi kwetekinoroji yewelding uye tekinoroji yekuongorora, mhando yewelded seam yakaramba ichivandudzwa, siyana uye mataurirwo epombi yesimbi yakashongedzerwa yave kuwedzera, uye simbi isina musono. pombi yakatsiviwa mundima dzakawanda uye dzakawanda.Welded simbi mapaipi akakamurwa kutwasanuka musono welded pombi uye spiral welded pombi maererano chimiro weld.

一.Classification ye Welded Pipes Welded chubhu

Mapombi akaiswa akaiswa mumapoka maererano nekushandiswa kwawo: akaiswawo mumipombi yakashongedzerwa, galvanizing welded pombi, okisijeni inovhuvhuta welded pombi, waya maoko, metric welded pombi, idler pombi, yakadzika tsime pombi pombi, mota pombi, transformer pombi, welded dzakatetepa. -mapaipi akaiswa madziro, mapaipi akasungwa asina kujairika uye mapaipi anomonereka.

二.Application Range ye Welded Pipe

Welded pombi zvigadzirwa zvinoshandiswa zvakanyanya mu boiler, mota, kuvaka ngarava, kuvaka light-uremu magonhi ezvimiro nemahwindo simbi, fenicha, akasiyana ekurima michina, scaffolding, waya yekuruka pombi, masherufu akakwira, midziyo uye zvichingodaro izvo inogona kusangana nezvinodiwa nemutengi, yakakosha isina kujairika welded pombi inogona kugadzirwa zvinoenderana nezvinodiwa nemushandisi.

三.THEORETICAL CLCULATION METHOD OF WELDED PIPE WEIGHT  

Pane mafomula ekuverenga huremu hwepombi yakasungwa.

Theoretical huremu pamita imwe yesimbi pombi (density yesimbi i7.85 kg/dm3)

Formula: W = 0.02466 (DS)S

Muchiverengero chekuverenga, huremu hwehuremu hweW-simbi pombi pamamita, kg/m;

D - Zita rekunze dhayamita resimbi pombi, mm;

S - zita remadziro ukobvu hwesimbi pombi, mm.

四.Tsanangudzo Yepamutemo uye Indasitiri Kushandiswa kwe Welded Pipe

Iyo mbishi inoshandiswa pa welded chubhu chigayo isimbi ndiro kana simbi tambo.Inogona kupatsanurwa muchoto yakashongedzwa pombi, yemagetsi welded pombi uye otomatiki arc welded pombi nekuda kweakasiyana welding tekinoroji.Maererano siyana nomoto mafomu, inogona kupatsanurwa yakatwasuka musono welded nyere uye spiral welded nyere.per kuguma chimiro, inogona kupatsanurwa denderedzwa welded nyere uye inokosha-zvakaumbwa welded nyere (square nyere sandara pombi etc.) .Welded pombi dzinogona kukamurwa muzvikamu zvinotevera pazvishandiso zvavo zvakasiyana uye mashandisiro:

1. GB/T3091-1993 (Galvanized Welded Steel Pipe for Low Pressure Fluid Conveyance)

Inonyanya kushandiswa kufambisa mvura, gasi, mhepo, oiri, kudziyisa mvura inopisa kana chiutsi uye mamwe akajairwa low pressure fluid uye zvimwe zvinangwa zvepombi.Mumiririri wayo zvinhu giredhi Q235A simbi.

2. GB/T3092-1993 (Galvanized Welded Steel Pipe for Low Pressure Fluid Conveyance)

Inonyanya kushandiswa kufambisa mvura, gasi, mhepo, oiri, kudziyisa mvura inopisa kana chiutsi uye mamwe akajairwa low pressure fluid uye zvimwe zvinangwa zvepombi.Mumiririri wayo zvinhu Q235A giredhi simbi.

3. GB/T 14291-1992 (Welded Pipe for Mine Fluid Transport)

Inonyanya kushandiswa kumugodhi wemhepo, dhiraivha, shaft gasi dhiraivha ine yakatwasuka seam welded simbi pombi.Mumiririri wayo zvinhu giredhi Q235A uye B simbi.GB/T 14980-1994 (Hombe Diameter Welded Steel Pipe for Low Pressure Fluid Conveyance).Inonyanya kushandiswa kuendesa yakaderera kudzvinyirira zvinwiwa zvakaita semvura, tsvina, gasi, mweya, kupisa chiutsi uye zvimwe zvinangwa.Mumiririri wayo zvinhu giredhi Q235A simbi.

4. GB/T12770-1991 (Welded Stainless simbi pombi ye mechanical structure)

Inonyanya kushandiswa kumichina, mota, mabhasikoro, fenicha, Hotera uye kushongedzwa kwehotera uye zvimwe zvikamu zvemakanika uye zvimiro.Zvishandiso zvayo zvinomiririra 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, nezvimwe.

GB/T12771-1991 (Welded Stainless Simbi Pipe yeFluid Transport)

Inonyanya kushandiswa kuendesa low-pressure corrosive media.

Zvishandiso zvinomiririra 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, nezvimwe.
