Kugadzira galvanizing inzira yekuisa zinc inodzivirira simbi kana simbi kudzivirira ngura. Maitiro aya anowanzo shandiswa mukugadzira mapaipi, kunyanya ayo anoshandiswa mumaindasitiri akasiyana-siyana akadai sekuvaka, mafuta negesi, uye mvura.Maitiro ekugadzirisa mapaipiZvakakosha pakuona kuti mapaipi emagetsi akasimba uye anogara kwenguva refu. Ngationgororei zvakadzama nezvemitemo yemagetsi emagetsi uye zvazvinoreva mumutsara wemagetsi emagetsi emagetsi.
Kugadzira mapaipizviyero zvinonyanya kugadzwa nesangano repasi rose reAmerican Society for Testing and Materials (ASTM). ASTM inogadza zviyero zvakananga zvemaitiro ekugadzira galvanizing, zvinosanganisira ukobvu hwe galvanized layer, kunamira kwe coating, uye mhando yese yerakarukwapamusoro. Mitemo iyi yakakosha pakuchengetedza kunaka kwepombi yesimbi yakabatidzwa uye kuona kuti inoshanda zvakanaka mumabasa akasiyana-siyana.
Imwe yemitemo yakakosha yemapaipi esimbi iASTM A123/A123M, iyo inotsanangura zvinodiwa zvemapepa esimbi, kusanganisira mapaipi. Mutemo uyu unoratidza ukobvu hwemapepa, kunamira uye kupedzisa kwemapaipi esimbi. Unopawo gwara rekuongorora nekuyedza mapombi.machira esimbikuve nechokwadi chekuti zvinodiwa zvinotevedzwa.
In mitsetse yekuisa magasi epombi, kutevedzera mitemo yeASTM A123/A123M kwakakosha pakugadzira mapaipi emhando yepamusoro egalvanized. Maitiro egalvanization anowanzo sanganisira matanho akati wandei, anosanganisira kugadziriswa pamusoro, kunyudzwa kwegalvanization nekupisa uye kugadziriswa mushure mekupisa. Danho rega rega rinofanira kutevedzera mitemo yeASTM kuti riwane ukobvu uye mhando yecoating inodiwa.
Kugadzirira pamusoro penzvimbo kunosanganisira kuchenesa mapaipi kubvisa ngura, makwande kana zvimwe zvinhu zvinogona kudziviriragalvanizingdanho iri rakakosha kuti pave nechokwadi chekuti chinhu chacho chinonamira zvakanaka.kuputira kwakarukwapamusoro pepombi. Maitiro ekupisa nekunyika galvanizing anosanganisira kunyudza mapaipi akacheneswa mubhavhu rezinc yakanyungudutswa, iyo inobatanidza nesimbi nesimbi kuti igadzire chifukidziro chinodzivirira..
Mushure mekugadzirisa magasi, pombi yacho ichagadziriswa mushure mekugadzirisa, izvo zvinogona kusanganisira kudzima, kupfava kana kutarisa ukobvu hwemagasi uye kunamira. Matanho aya ekugadzirisa mushure mekugadzirisa akakosha kuona kuti pombi yegasi inosangana nezvinodiwa neASTM uye yakagadzirira kushandiswa mumhando dzakasiyana-siyana dzekushandisa.
Kutevedzerakugadzika mapaipimitemo haingovimbisi chete kunaka uye kugara kwenguva refu kwepombi, asiwo inobatsira pakushanda kwayo kwenguva refu uye kuramba ngura. Pombi dzakagadzirwa nesimbi dzinoenderana neASTM dzakakodzera nzvimbo dzekunze, dzine hunyoro hwakawanda uye dzinoparadza, zvichiita kuti dzive dzakakodzera kushandiswa kwakadai sekuparadzirwa kwemvura, rutsigiro rwechivakwa uye masisitimu emapaipi emaindasitiri.
Muchidimbu, mitemo yekuisa mapombi mumagetsi inotsanangurwa neASTM International inoita basa rakakosha mukugadzirwa kwemagetsi mumagetsi. Kutevedzera mutemo uyu kunoita kuti zvive pachena kutipombi yakabatidzwainosangana nezvinodiwa zvinodiwa pakukora kwejira, kunamira uye kunaka kwese. Nekutevedzera zviyero zveASTM,vagadziriinogona kugadzirapombi yepamusoro-soro yakabatidzwaiyo inopa dziviriro yepamusoro yengura uye hupenyu hwebasa mumhando dzakasiyana dzemaindasitiri nedzemabhizinesi.
