Pombi yakatenderedzwa yakarukwa

Mapaipi esimbi akakamurwa kuita mhando mbiri: galvanizing inodziya uye electro-galvanizing. Layer ye galvanizing inodziya yakakora, mutengo we electro-galvanizing wakaderera, uye pamusoro payo hapanyatsotsvedzerera. Mapaipi akasungirirwa anofefetera okisijeni: anoshandiswa pamapaipi anofefetera okisijeni anogadzira simbi, kazhinji mapaipi esimbi akasungirirwa dhayamita diki, ane hunyanzvi husere hunotangira pa 3/8 kusvika 2 inches. Shandisa 8, 10, 15, 20 kana Yakagadzirwa nesimbi ye195-Q235, kudzivirira ngura, zvakakosha kuita kurapwa kwe aluminizing.

Pombi yakasungirirwa yakagadzirwa nesimbi inopisa (hot-dip galvanized weld) ndeyekuita kuti simbi yakanyungudutswa iite seyakasanganiswa nesimbi kuti igadzire layer yesimbi, kuitira kuti matrix necoatings zvibatanidzwe. Kuisa galvanization mukupisa (hot-dip galvanizing) ndiko kutanga kwaisa pombi yesimbi. Kuti ibvise iron oxide pamusoro pepombi yesimbi, mushure mekuisa pombi, inocheneswa mutangi neammonium chloride kana zinc chloride aqueous solution kana mixed aqueous solution yeammonium chloride ne zinc chloride, yozotumirwa kuIn the hot dip plating tank. Kuisa galvanization mukupisa kune zvakanakira zvekuisa pombi zvakafanana, kunamatira kwakasimba uye kugara kwenguva refu.

Kuisa magasi emagetsi muchando kunoreva kushandisa magetsi, uye huwandu hwemagasi hudiki kwazvo, 10-50g/m2 chete, uye kuramba kwayo ngura kwakaipa kupfuura kwemapaipi emagetsi anonyudzwa mukupisa.
