Kukosha Kwepombi Dzakaviriswa Nemapombi uye Polyurethane Lined Pipe muPipe Welding
Kaviri welded pipeinoreva pombi yakasungwa nekaviri kuti igadzire mubatanidzwa wakasimba, unogara wakasimba.Rudzi urwu rwepombi runowanzoshandiswa mukuvaka pombi apo welding quality uye simba zvakakosha.Iyo kaviri welding process inosanganisira kushandisa welding matekiniki kusanganisa mapaipi maviri akaparadzana pamwechete kuti ave nechokwadi chekubatana kwakasimba uye kusina musono.Izvi hazvisi izvo chete zvinowedzera simba rose uye kusimba kwepombi, zvakare zvinoderedza njodzi yekuremara kwewelding uye inogona kudonha.
Polyurethane lined pipe, kune rumwe rutivi, ipombi yakavharwa ne polyurethane coating iyo inopa imwezve dziviriro kubva pakuora, abrasion, uye kurwisa kwemakemikari.Iyo lining inoshandiswa kune mukati mukati mepombi kugadzira chipingamupinyi pakati pemvura inotakurwa uye simbi pamusoro pepombi.Polyurethane lined pombi inonyanya kubatsira kune mapaipi anoshandiswa kutakura zvinhu zvinoparadza kana kushanda munzvimbo dzakaomarara.Polyurethane linings haingowedzere hupenyu hwepombi dzako, zvakare inoderedza njodzi yekuvuza uye mari yekugadzirisa.

Mukuwedzera, kubudirira kwekugadzira kwespiral simbi mapaipiyakakwirira zvikuru kupfuura iyo yepombi dzesimbi dzisina musono.Kune pombi isina musono, maitiro ekugadzira anosanganisira extruding simbi yakasimba billet kuburikidza netsvimbo ine perforated, zvichikonzera kunonoka uye kwakaoma kugadzirwa maitiro.Kusiyana neizvi, spiral welded pombi inogona kugadzirwa mumadhayamita akakura uye kureba, zvichikonzera kupfupika kwekugadzira nguva uye kuwedzera kugona.Izvi zvinoita kuti pave nekuenderana kwepombi dzemhando yepamusoro munguva pfupi, zvichiita kuti ive yakavimbika uye inochengetedza nguva mhinduro kune akasiyana maindasitiri.
Imwe mukana unokosha we spiral welded pombi ndiko kupikisa kwavo kwakanyanya kumanikidziro ekunze uye kushushikana kwemagetsi.Mawelds anopa kuwedzera kusimba, achibvumira mapombi aya kuti amire kudzvinyirirwa kwepamusoro pane mapaipi asina musono.Ichi chivakwa chakanyanya kukosha kune mashandisirwo muindasitiri yemafuta negasi, uko mapaipi ari pasi pekumanikidzwa kukuru kwemukati nekunze.Nekushandisa spiral welded pombi, makambani anogona kuve nechokwadi chekufambisa kwakachengeteka uye kwakanaka kwezvinhu izvi zvakakosha.
Mune pombi welding, musanganiswa wepiipi yakasungwa kaviri uye polyurethane lined pombi inopa akawanda mabhenefiti.Chokutanga uye chinonyanya kukosha, kushandiswa kwepombi-welded pombi kunovimbisa kutendeseka kwechimiro chepombi, kuderedza mukana wekugadzirisa kukanganisa uye kukundikana kunotevera.Izvi zvinonyanya kukosha munzvimbo dzeindasitiri uko mapaipi ari pasi pekumanikidzwa kwakanyanya uye kushanduka kwekushisa.Pamusoro pezvo, kushandiswa kwemapombi ane polyurethane-lined kunopa imwe dhizaini yekudzivirira kubva mukuora uye kupfeka, zvichiwedzera kusimba kwepombi uye hupenyu hwehupenyu.
Mukuwedzera, kushandiswa kwepombi-welded pipe uye polyurethane-lined pipe inogona kupa mari yekuchengetedza kune vanofambisa pombi.Iyo yakawedzerwa simba uye kusimba kwekaviri welded pombi inogona kuderedza kudiwa kwekugadziriswa uye kugadzirisa nguva nenguva, kuchengetedza nguva nemari mukufamba kwenguva.Saizvozvo, iyo inodzivirira yakapihwa ne polyurethane-lined pombi inogona kuwedzera hupenyu hwesevhisi yepombi, nekudaro kuderedza kutsiva uye kugadzirisa mari.
Mukupedzisa, kushandiswa kwepombi dzakasungwa kaviri uye pombi dzakaiswa polyurethane kwakakosha mukunama pombi.Izvi zvinoumba kwete chete kuvimbisa kuvimbika kwechimiro uye kusimba kwepombi, asi zvakare zvinopa kuchengetedzwa kwakakodzera kubva mukuora, abrasion uye kurwisa kwemakemikari.Nekubatanidza aya matekinoroji epamberi mukuvaka pombi, vashandisi vanogona kuwana yakakwira mwero wekuvimbika, kuita uye mutengo-unoshanda kune yavo pombi masisitimu.
