Kukosha KweSpiral Welded Mapaipi E Underground Natural Gas Pipelines
Evolution ye welded pombi uye spiral welding tekinoroji:
Welded chubhuskuita basa rakakosha muinjiniya nekuvaka zvemazuva ano.Kwemakore, nzira dzakasiyana dzekushongedza dzakagadzirwa, imwe neimwe iine mabhenefiti ayo akasiyana.Pakati peaya matekinoroji, spiral welding inozivikanwa nekugona kwayo kugadzira emhando yepamusoro machubhu ane simba repamusoro uye nekuvimbika.Spiral welded pombi inogadzirwa nekuramba ichitenderedza tambo yesimbi kuburikidza nenhevedzano yema roller kuti iite spiral shape.Mipendero yemipendero inozobatanidzwa pamwe chete kugadzira pombi yakasimba uye isingadere.

Zvakanakira zve spiral welded pipe:
1. Kuwedzera simba uye kusimba: Kuenzaniswa nemusono wakatwasuka kana wakatwasuka musono wakaiswa pombi,spiral welded pombiratidza simba rakakosha nekuda kwekuenderera mberi spiral weld seam.Kuenderera mberi welds kunowedzera kugona kwepombi kumirisana nepamusoro mukati nekunze kumanikidzwa, zvichiita kuti ive yakanakira mitsara yepasi pegasi.
2. Kuramba kushushikana nekuora:Mutsara wegasi wepasimambure ega ega anowanzosangana nekunetseka kwakasiyana-siyana nekuda kwekufamba kwevhu, shanduko yekushisa uye mitoro yekunze.Spiral welded mapombi ane elastic uye anopa zvakanakisa kuramba kune izvi zvinonetsa, zvichideredza njodzi yekukuvara kana kutadza.Pamusoro pezvo, mapombi aya anogona kuve akaputirwa nejasi rekudzivirira kuti awedzere kusimbaradza kusakara, kuve nechokwadi chehupenyu hurefu hwesevhisi.
3. Enhanced flexibility: Spiral welded pombi inoshanduka-shanduka nekuda kwechimiro chayo chekutenderera, ichichibvumira kuchinjika kune akasiyana terrains uye yekuisa mamiriro.Uku kuchinjika kunoita kuti mapaipi haanyanye kubatwa nepasi subsidence kana kuchinjika, zvichipa yakavimbika gasi kugovera network.
4. Kubhadhara mari: Nzira yekugadzira ye spiral welded pipes inoshanda zvikuru, nokudaro kuchengetedza mari.Mapombi aya anowanikwa muhurefu hwakareba, zvichideredza huwandu hwemajoini anodiwa pakuiswa.Majoini mashoma haangorerutsa maitiro ekuvaka, asi zvakare anobatsira kuvandudza kuperera kwepasi pevhu gasi pombi, kuderedza mukana wekudonha kana kutadza.
Mukupedzisa:
Sezvo kudiwa kwegasi rechisikigo kuri kuramba kuchikura, nzira dzakavimbika uye dzinoshanda dzekugovera dzakakosha, kunyanya pamapaipi epasi pegasi egasi.Spiral welded pombi dzakaratidza kuve mhinduro yakanaka, kusanganisa simba, kusimba, kushushikana uye kusadzivirirwa nekuora, kuchinjika uye mutengo-kushanda.Nekudyara mumhando yepamusoro spiral welded pombi, makambani ekuparadzira gasi anogona kuvaka chivakwa chakasimba chinovimbisa kuchengetedzwa uye kusakanganiswa kwegasi rechisikigo kunharaunda, zvichibatsira mukukura kwavo nekusimudzira.
