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, nekukurumidza kusimudzira kwemhando yepamusoro-yemhando yekugadzira mitsetse yekugadzira uye kufambira mberi kwehunyanzvi hwekugadzira welding uye tekinoroji yekuongorora, mhando yewelded seam yakaramba ichivandudzwa, kusiyanisa uye kutsanangurwa kwepombi yesimbi yakashongedzwa 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.

Poshi.Classification ye Welded Pipes Welded chubhu

Mapombi akaiswa akaiswa mumapoka maererano nekushandiswa kwawo: akaiswawo mumhando dzepombi dzakasungwa, galvanizing welded pombi, okisijeni inofuridza 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.

piri.Application Range ye Welded Pipe

Welded pombi zvigadzirwa zvinoshandiswa zvakanyanya muboiler, 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 abnormal welded pombi inogona kugadzirwa zvinoenderana nezvinodiwa nemushandisi.

tatu.THEORETICAL KUYERERA METHOD YE WELDED PIPE UREMBO  

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.

Four.Tsanangudzo Yepamutemo uye Kushandiswa kweIndasitiri ye Welded Pipe

Iyo mbishi inoshandiswa pa welded chubhu chigayo isimbi ndiro kana simbi tambo.Inogona kupatsanurwa kuita muchoto welded 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 flat nyere etc.) .Welded pombi dzinogona kukamurwa muzvikamu zvinotevera pazvakasiyana zvinhu uye mashandisiro:
