Kukosha KweSimbi Tubular Mirwi Mumvura Yepasi Pevhu Kuvaka
Paunenge uchigadzira mitsara yemvura yepasi, kusarudzwa kwezvinhu kunotora basa rakakosha pakuona kutendeseka kwenguva refu uye kugona kwehurongwa.Simbi Tubular Murwis, inowanzozivikanwa semapombi, anoshandiswa zvakanyanya nekuda kwesimba rayo repamusoro, kusagadzikana kwekuora uye kuita zvakasiyana.Muchiitiko ichi, spiral welded pombi isarudzo yakanakira yekuvaka pombi yemvura yepasi pevhu nekuda kweiyo chaiyo yakatarwa uye zvakanakira.
Spiral welded pombi inogadzirwa uchishandisa spiral seam welding process, iyo inogona kuumba inoenderera inotenderera weld pamwe nehurefu hwepombi.Iyi welding tekinoroji haingoiti chete kuenderana uye yemhando yepamusoro yewelds, asi zvakare inogadzira mapaipi ane madhayamita akakura uye madziro akakora, zvichiita kuti aenderane nemamiriro akaomarara epasi pevhu pombi yekuisa pombi.

Imwe yeakakosha zvirevo zve spiral welded pombi kugona kuwana yakakura dimensional kurongeka uye kutwasanuka kana ichienzaniswa neyakajairwa musono seam welded pombi.Iyi ficha inonyanya kukosha pakuvaka mutsara wemvura yepasi, uko kurongeka kwepombi uye kuyerera kwemvura kwakafanana kwakakosha pakuita kwakaringana system.Uye zvakare, iyo yakatsetseka yemukati yepasi pe spiral welded pombi inoderedza kukweshera uye kudonha kwekumanikidza, zvichibatsira kuwedzera kuyerera kwemvura uye kuderedza kushandiswa kwesimba.
Mukuwedzera, spiral welded pombi inowanikwa mumhando dzakasiyana-siyana uye machira kuti asangane nemamiriro ekunze uye ekushanda zvinodiwa.Kubva kubva pacarbon simbi kusvika kune alloy uye simbi isina tsvina, mapaipi aya anopa kusarudzika kuramba ngura, kuita kwemakemikari uye kusagadzikana kwemagetsi, kuve nechokwadi chekuvimbika kwenguva refu mumashandisirwo emvura yepasi.Pamusoro pezvo, machira ekudzivirira akadai se epoxy, polyethylene, uye polyurethane anogona kuiswa kuti awedzere kusimba uye hupenyu hwesevhisi yepiral welded pombi, kunyanya muvhu rinoora uye mamiriro emvura yepasi.
Panyaya yekumisikidza, Simbi Tubular Piles, kusanganisira spiral welded pombi, ine zvakakosha mukuvaka pombi yepasi pemvura.Kukwanisa kwavo kutakura mutoro uye kutendeseka kwemaitiro kunobvumira kuvigwa kwakadzika uye kutsigirwa kwemvura, kunyange muvhu rakaoma uye geological mamiriro.Uye zvakare, huremu huremu hwemapombi esimbi hunobatsira kubata uye kutakura, kuderedza nguva yekuisa uye mutengo.Spiral welded pombi inogona kubatanidzwa nyore nyore uchishandisa akasiyana-siyana ekubatanidza masisitimu, ichipa inosiyana uye inoshanda mhinduro yemapurojekiti emutsara wemvura yepasi.
Muchidimbu, kushandiswa kweSimbi Tube Piles (kunyanya spiral welded pipes) yakakosha pakuvaka kunobudirira kwepombi dzepasi.Nekutsanangurwa kwayo kwakasiyana-siyana, kunosanganisira kurongeka kwepamusoro-soro, kushorwa kwecorrosion uye kuchinjika kwekuisa, spiral welded pombi inopa iyo yakanakisa kusanganisa kwesimba uye kuita kwenguva refu yemvura pombi kuperera.Sezvo kudiwa kwezvivakwa zvemvura zvakavimbika uye zvinogara zvichiramba zvichikura, kukosha kwekushandisa kwemhando yepamusoroSteel Tube Pilesmumvura yepasi pevhu kuvaka hakugone kuwedzeredzwa.
