Spiral Welded Pipes For Natural Gas Pipelines

Tsanangudzo Pfupi:

Spiral welded pombi chigadzirwa chakasiyana-siyana chinogona kushandiswa mumaindasitiri akasiyana siyana neminda.Nekusimba kwayo kwechimiro uye kusimba, chave chinhu chakakosha mumapurojekiti ekupa mvura, indasitiri yepetrochemical, indasitiri yemakemikari, indasitiri yemagetsi, kudiridza kwekurima, uye kuvaka maguta.Ingave yekufambisa kwemvura, kufambisa gasi kana zvinangwa zvechimiro, spiral welded pombi isarudzo yakavimbika uye inoshanda.

Spiral welded pipe, inozivikanwawo sechubhuweld, inogadzirwa uchishandisa advanced welding tekinoroji kugadzira chigadzirwa chakasimba.Iyo inoumbwa neinoenderera yakatenderedzwa yejoini inoumbwa ne spiral welding simbi mitsetse pamwechete.Ichi chakasarudzika chimiro chinopa simba risingaenzaniswi, zvichiita kuti ive yakanaka kune inoda maapplication akadaimitsara yegasi chaiyo.

Imwe yemashandisirwo makuru espiral welded pombi ndeyekutakura gasi remusikirwo.Iyo yakanyatso gadzirwa uye inogadzirwa kuti imirisane nepamusoro-inomanikidza nharaunda yakabatana neakasikwa gasi kutapurirana.Spiral welded pombi inovimbisa kuchengetedzeka uye kwakanyatso kuendesa gasi rechisikigo kumaindasitiri nevatengi, kuve nechokwadi chekupihwa kwakavimbika uye kuderedza chero angangoita kuvuza kana tsaona.

Pamusoro pe,spiral welded pombianoshandiswawo zvakanyanya mukupa mvura uye madhiraini masisitimu.Kuvaka kwayo-kusingabvumire kudonha uye kusadzivirirwa kunoita kuti ive sarudzo yakanaka yekutakura mvura kubva kune kwainoenda.Nekuda kwekugara kwayo, inokwanisa kumira nemamiriro ezvinhu akaomarara anowanzo sangana mumapurojekiti ekupa mvura, ichipa nharaunda nemaindasitiri mhinduro dzenguva refu, dzakavimbika.

Hollow-Section Structural Mapaipi

Muindasitiri yepetrochemical, spiral welded pombi inoita basa rakakosha mukutakura gasi, chiutsi, liquefied petroleum gasi uye zvimwe zvinhu.Simba rayo repamusoro uye kuramba kwecorrosion kunoita kuti ive sarudzo yakanakisa yekufambisa zvinhu izvi zvinoputika.Ingave yakakura petrochemical chirimwa kana kuisirwa kudiki, spiral welded pombi inovimbisa kufambiswa kwakachengeteka uye kwakanaka kwezvinhu izvi zvakakosha.

Uyezve, chimiro che spiral welded pipe chinoshandiswa zvakanyanya.Inowanzo shandiswa sekuputira machubhu enheyo mumapurojekiti ekuvaka, ichipa tsigiro inodiwa uye kugadzikana.Kusimba kwepombi kunoitawo kuti ive sarudzo yekutanga yemabhiriji, madocks, migwagwa uye zvivakwa zvekuvaka.Kugona kwavo kutsungirira mitoro inorema uye masimba ekunze anovimbisa kuchengetedzwa uye kutendeseka kwezvivakwa izvi, zvichiita kuti zvive chinhu chakakosha mumunda wekuvaka kwemaguta.

Mukupedzisa, spiral welded pombi (inozivikanwawo sepombi weld) inopa mhinduro inoshanda uye yakasimba kune akasiyana maindasitiri nezvikamu.Yakasiyana-siyana yekushandiswa kwayo inosanganisira mvura yekupa engineering, petrochemical indasitiri, indasitiri yemakemikari, indasitiri yemagetsi emagetsi, kudiridza kwekurima, kuvaka maguta, etc. Ingave ichishandiswa kutakura zvinwiwa kana magasi, kana nekuda kwezvinangwa, spiral welded pombi ndeyechokwadi uye. sarudzo inoshanda.Nesimba rayo rakasiyana, elasticity uye corrosion kuramba, inoramba iri chinhu chakakosha muindasitiri yemazuva ano.
