Mapaipi esimbi ane galvanizedakakamurwa kuita pombi dzesimbi dzinotonhora uye pombi dzesimbi dzinopisa.Mapaipi anotonhora esimbi akarambidzwa.Mumakore ekuma1960 nema1970, nyika dzakasimukira pasi rose dzakatanga kugadzira mhando itsva dzepombi uye zvishoma nezvishoma dzakarambidza mapaipi emarara.Mapazi nemakomisheni mana anosanganisira bazi rezvekuvaka reChina aburitsawo gwaro rinoti mapaipi ane marata ari kurambidzwa kushandiswa sepombi dzemvura kubva muna 2000. Mapombi emvura inotonhora munharaunda dzichangovakwa haawanzo shandisa marata, uye mamwe mvura inopisa. pombi mune dzimwe nharaunda dzinoshandisa mapaipi ane galvanized.Hot-dip galvanized simbi mapaipi ane zvakasiyana-siyana zvekushandisa mukudzivirira moto, simba nemigwagwa mikuru.
Applications
Kupisa-dhipi kwakakurudzira simbi mapaipi anoshandiswa zvakanyanya mukuvaka, michina, migodhi yemarasha, makemikari, simba remagetsi, njanji mota, indasitiri yemotokari, migwagwa mikuru, mabhiriji, midziyo, midziyo yemitambo, michina yekurima, petroleum michina, michina yekutsvaga, kuvaka greenhouse nezvimwe. maindasitiri ekugadzira.
Galvanized steel pombi ipombi yesimbi yakashongedzerwa ine inopisa-dip galvanized kana electro-galvanized layer pamusoro pepamusoro.Galvanizing inogona kuwedzera kushorwa kwepombi dzesimbi uye kuwedzera hupenyu hwesevhisi.Mapaipi ane galvanized anoshandiswa zvakanyanya.Pamusoro pekushandiswa semapombi epombi ezvinwiwa zvakaderera-zvinodzvinyirira zvakaita semvura, gasi, uye oiri, anoshandiswawo sepombi dzemafuta uye pombi dzemafuta muindasitiri yepetroleum, kunyanya muminda yemafuta ekumahombekombe, uye mahita emafuta nemacondenser. mumakemikari ekubika midziyo.Mapombi ezvinotonhorera, marasha distillation anowachisa oiri anotsinhanisa, uye pombi dze trestle mirwi, anotsigira mafuremu ematani emugodhi, nezvimwe.

Hot dipgalvanized pipe
Hot-dip galvanized pipe ndeyekuita kuti simbi yakanyungudutswa iite pamwe nesimbi matrix kuti ibudise alloy layer, kuitira kuti matrix nejasi zvibatane.Kupisa-dip galvanizing ndiko kutora pombi yesimbi kutanga.Kuti ubvise iron oxide pamusoro pepombi yesimbi, mushure mekunhonga, inocheneswa mutangi yeammonium chloride kana zinc chloride aqueous solution kana yakasanganiswa aqueous solution yeammonium chloride uye zinc chloride, yozotumirwa kune inopisa dip kugeza.Kupisa-dip galvanizing kune zvakanakira kupfeka yunifomu, kunamatira kwakasimba uye hupenyu hurefu hwebasa.Iyo inopisa-dipgalvanized steel pipesubstrate inosangana nemaitiro akaomarara emuviri uye emakemikari neyakanyungudutswa yeplating mhinduro kuti igadzire inodzivirira corrosion zinc-iron alloy layer ine compact chimiro.Iyo alloy layer inosanganiswa neyakachena zinc layer uye simbi pombi substrate, saka ine yakasimba corrosion resistance.
Pombi inotonhora
Cold galvanized pipe is electro-galvanized, uye huwandu hwemarara hudiki kwazvo, chete 10-50g/m2.Kudzivirirwa kwayo kwekuora kwakasiyana zvakanyanya neiyo inopisa-dip galvanized pipe.Kuti uve nechokwadi chemhando, vazhinji vanogara vakagadzika pombi vanogadzira havashandisi electro-galvanized (inotonhora plating).Iwo chete mabhizinesi madiki ane michina yechinyakare anoshandisa electrogalvanizing, uye hongu mitengo yavo yakachipa.Bazi rezvekuvaka rakapa zviri pamutemo mutemo wekubvisa pombi dzinotonhora dzine tekinoroji yechinyakare, uye kusashandisa mapaipi anotonhora emagetsi emvura negasi.Iyo galvanized layer yeinotonhora galvanized simbi pombi ndeye electroplating layer, uye zinc layer yakazvimiririra yakaturikidzana nesimbi pombi substrate.Iyo zinc layer yakatetepa, uye zinc layer inongoomerera kune simbi pombi substrate uye iri nyore kudonha.Naizvozvo, kusaita ngura kwayo hakuna kunaka.Mudzimba dzichangovakwa, zvinorambidzwa kushandisa pombi dzesimbi dzinotonhora sepombi dzinopa mvura.
