Spiral seam pombi yePIGY MAHARA PIPES Inoratidza Mufananidzo

Tsananguro pfupi:

Mukuraramai mukuvaka misangano, izvo zvinoshandiswa zvinoshandiswa kutamba basa rakakosha muhuwandu hwekushanda uye kushanda kweprojekiti. Chimwe chinhu chinonyanya kukosha kune indasitiri indarustretry ndeye spiral yelted pombi. Iyi pombi dzinowanzo shandiswa mune dzakasiyana siyana dzekushandisa senge masaini uye mapepa egasi, uye zvibayiro zvadzo zveSeam uye zvakashora kuti zviite kuti kuve nekuita kwavo kuita. Mune ino blog, isu tichaongorora zvakadzamaSpiral Welded Pipe Sitefication uye kukosha kwavo muindasitiri yekuvaka.

SPIRAL SEAM PIPEsinovakwa uchishandisa nzira inonzi iyo Spiral Welding maitiro. Maitiro acho anosanganisira kushandisa marobhoti anopisa-simbi kuti aumbe mune cylindrical chimiro uye akabva awirirana pamwe chete neSpiral seam. Mhedzisiro yacho pombi ine simba rakakura uye kusimba, zvichiita kuti zviite zvakakodzera kuti zviwedzere huwandu hwekushandisa. Aya mapepa anoshandisaWelded TubeTekinoroji panguva yekuvaka, inovimbisa kuti vanopikisa zvakasiyana-siyana zvezvinhu zvemhoteredzo uye nekumanikidzwa, kuita kuti vave vakanakira pasi pevhu uye pasi pemvura.

Mukupfupikisa, iyo yepadenga yePIPE nzira inokosheswa kuita basa ravo mukuvaka misangano. Ingave ichishandiswa kune main masi kanamitsara yegesi, mapipi aya anopa simba risingafadzi, kusimba uye kusanganisa, kuzviita kunokosha munyika yemazuva ano. Nekunamatira pamashiripiti uye nemirairo, kushandiswa kweiyo spiral seam mapaipi ekuchengetedza uye kushanda kwehurongwa hwekushushikana-tsika dzekusimudzira, kuchiva nzira yekutsigira kukura uye kufambira mberi munharaunda.
