Hot-Dip Galvanized Pipe
Hot-dip galvanized pipe
Iyo inopisa-dip galvanized pombi ndeyekuita kuti simbi yakanyungudutswa iite nesimbi matrix kuti ibudise alloy layer, kuitira kuti matrix nejasi zvibatane.Kupisa-dip galvanizing ndiko kutanga kutora pombi yesimbi.Kuti ubvise iron oxide pamusoro pepombi yesimbi, mushure mekunhonga, inocheneswa mutangi neammonium chloride kana zinc chloride aqueous solution kana yakasanganiswa aqueous solution yeammonium chloride uye zinc chloride, yozotumirwa inopisa dip plating tank.Kupisa-dip galvanizing kune zvakanakira kupfeka yunifomu, kunamatira kwakasimba uye hupenyu hurefu hwebasa.Matrix yepombi yesimbi inopisa-dip inopindirana nechimiro chakaoma uye kemikari inosangana neyakanyungudutswa yeplating solution kuti igadzire chidziviriro chinodzivirira zinc-iron alloy layer ine compact structure.Iyo alloy layer inosanganiswa neiyo yakachena zinc layer uye simbi pombi matrix, saka kushora kwayo kwakasimba.
Pombi inotonhora
Cold galvanized pipe is electro-galvanized, uye uwandu hwegalvanizing iduku zvikuru, chete 10-50g/m2, uye kushorwa kwayo kwekuora kwakasiyana zvakanyanya pane iyo inopisa-dip galvanized pipe.Formal galvanized pombi vagadziri, kuitira kuti vave nechokwadi chemhando, vazhinji vavo havashandisi electro-galvanized (kutonhora plating).Iwo chete mabhizinesi madiki ane zvidiki uye zvechinyakare michina anoshandisa electro-galvanization, uye hongu mitengo yavo yakachipa.Bazi rezvekuvaka razivisa zviri pamutemo kuti mapombi anotonhora ane hunyanzvi hwechinyakare anofanirwa kubviswa, uye mapombi anotonhora haabvumidzwe kushandiswa sepombi dzemvura negasi.Iyo galvanized layer yeinotonhora galvanized steel pipe is electroplated layer, uye zingi layer inoparadzaniswa nesimbi pombi substrate.Iyo zinc layer yakatetepa, uye zinc layer inongoomerera kune yesimbi pombi base uye inodonha nyore.Naizvozvo, kushorwa kwaro kwakashata.Mudzimba dzichangovakwa, zvinorambidzwa kushandisa pombi dzesimbi dzinotonhora sepombi dzinopa mvura.
Nominal wall ukobvu (mm): 2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5.
Coefficient parameters (c): 1.064, 1.051, 1.045, 1.040, 1.036, 1.034, 1.032, 1.028.
Cherechedza: Iyo mechanical properties yesimbi indekisi yakakosha kuti ive nechokwadi chekupedzisira kushandiswa kwekushanda (mechanical properties) yesimbi, uye zvinoenderana nemakemikari ekuumbwa kwesimbi uye kupisa kwekupisa.Mune iyo simbi pombi mwero, zvinoenderana neakasiyana mashandisirwo ezvinodiwa, iyo tensile zvivakwa (tensile simba, goho simba kana goho poindi, elongation), kuomarara uye kuomarara indexes inotsanangurwa, pamwe nepamusoro uye yakaderera tembiricha zvivakwa zvinodiwa nevashandisi.
Simbi mamakisi: Q215A;Q215B;Q235A;Q235B.
Test pressure value/Mpa: D10.2-168.3mm is 3Mpa;D177.8-323.9mm is 5Mpa
