Kuti pave nekusagadzikana kwengura, pombi yesimbi (pombi nhema) inogadzirwa negalvanized.Pombi yesimbi yakakamurwaYakakamurwa kuita mhando mbiri dze "hot dip galvanized" uye "electrical galvanized". "Hot dip galvanizing layer" yakakora uye mutengo we "electrical galvanizing" wakaderera, saka kune mapaipi esimbi akaumbwa nesimbi. Mazuva ano, nekukura kweindasitiri, kudiwa kwemapaipi esimbi akaumbwa nesimbi kuri kuwedzera.
Zvigadzirwa zvemapaipi esimbi akagadzika anopisa zvakashandiswa muminda yakawanda, mukana wekushandisa galvanized inodziya nekupisa ndeyekuti inogara kwenguva refu mukudzivirira ngura. Inoshandiswa zvakanyanya munhare yemagetsi, nhare yekutaurirana, njanji, dziviriro yemigwagwa, nhare dzemagetsi emugwagwa, zvikamu zveMarine, zvikamu zvesimbi zvekuvaka, zvivakwa zve substation ancillary facilities, indasitiri yemwenje nezvimwewo.
Kupisa galvanizing kunoreva kutanga nekunhonga pombi yesimbi, kuitira kubvisa iron oxide pamusoro pepombi yesimbi, mushure mekunhonga, kuburikidza neammonium chloride kana zinc chloride aqueous solution kana ammonium chloride uye zinc chloride mixed aqueous solution tank yekuchenesa, uye wozopinda muhot dip plating tank. Kupisa galvanizing kune zvakanakira zvekuputira zvakafanana, kunamira kwakasimba uye hupenyu hurefu hwebasa. Maitiro mazhinji ari kuchamhembe anoshandisa nzira yekudzoreredza zinc yegalvanized belt direct coil pipe.
Hupenyu hwemapaipi esimbi anonyungudutswa nekupisa munzvimbo dzakasiyana hahuna kufanana: makore gumi nematatu munzvimbo dzine maindasitiri akawanda, makore makumi mashanu mugungwa, makore zana nemana mumaguta, uye makore makumi matatu muguta.
