Musiyano pakati pe-pre-galvanized uye inopisa-dip galvanized simbi pombi, sei kutarisa kunaka kwayo?

Musiyano pakatipre-galvanized pipeuyeHot-DIP Galvanized Steel Pipe

1. Musiyano mukuita: Pombi yakanyungudutswa inopisa inonyudzwa nekunyudza pombi yesimbi mu zinc yakanyungudutswa, nepo.pre-galvanized pipeyakavharwa zvakaenzana ne zinc pamusoro pesimbi strip ne electroplating process.

2. Musiyano weStructural: Hot-dip galvanized pombi itubular chigadzirwa, nepo pre-galvanized simbi pombi chigadzirwa chine hupamhi hukuru uye hudiki hudiki.

3. Zvishandiso zvakasiyana: Mapombi anopisa anopisa anonyanya kushandiswa kutakura zvinwiwa uye magasi, senge pombi dzemvura, pombi dzemafuta, nezvimwewo, nepo pombi dzesimbi dzakagara dzakagadzirwa dzichinyanya kushandiswa kugadzira zvigadzirwa zvesimbi zvakasiyana, senge zvikamu zvemotokari, imba. mabhomba emidziyo nezvimwe zvakadaro.

4. Different anti-corrosion performance: hot-dip galvanized pombi ine zvirinani anti-corrosion performance nekuda kwekukora kwemalata layer, nepo galvanized simbi tambo ine kushomeka kweanti-corrosion performance nekuda kwekutetepa kwemalata.

5. Mari dzakasiyana-siyana: nzira yekugadzirwa kwepombi inopisa-dip galvanized pipe inenge yakaoma uye inodhura, asi nzira yekugadzirwa kwepombi yesimbi iri nyore uye yakaderera.

Kuongororwa kwepre-galvanized uye inopisa-dip galvanized steel pipe quality
1. Kuongororwa kwekuonekwa
Kupera kwepamusoro: Kutariswa kwechitarisiko kunonyanya kunetseka kuti pamusoro pepombi yesimbi yakati sandara uye yakatsetseka, pasina zviri pachena zinc slag, zinc tumor, kuyerera kwakarembera kana kumwe kukanganisa kwepamusoro. Yakanaka galvanized simbi pombi yepamusoro inofanira kuva yakatsetseka, isina mabubbles, isina kutsemuka, isina zinc bundu kana zingi inoyerera yakaturika uye humwe hurema.

Ruvara uye kufanana: Tarisa kana ruvara rwepombi yesimbi rwakafanana uye runopindirana, uye kana pane kugoverwa kusina kuenzana kwezinc layer, kunyanya mumasowe kana nzvimbo dzakasungirirwa. Pombi yesimbi inopisa-dip inowanzoita chena kana kuti isina-chena, nepo pombi yesimbi isati yagarwa inogona kupenya zvishoma muruvara.

2. Zinc ukobvu kuyerwa
Ukobvu Gauge: Hukobvu hwezinc layer hunoyerwa pachishandiswa geji yakavharidzirwa ukobvu (eg magnetic kana eddy current). Ichi chiratidzo chakakosha chekuona kana zinc coating inosangana nezvinodiwa. Pombi yesimbi inopisa-dip kazhinji ine zinc layer yakakora, kazhinji iri pakati pe60-120 microns, uye pre-galvanized simbi pombi ine zinc layer yakatetepa, kazhinji iri pakati pe15-30 microns.

Nzira yehuremu (sampling): Samples inoyerwa zvichienderana nechiyero uye huremu hwezinc layer pane unit unit inotarwa kuona ukobvu hwezinc layer. Izvi zvinowanzogadziriswa nekuyera huremu hwepombi mushure mekunhonga.

Zvinodiwa zvakajairwa: Semuyenzaniso, GB/T 13912, ASTM A123 uye mamwe mazinga ane zvakajeka zvinodiwa pakukora kwezinc layer, uye zinc layer ukobvu hunodiwa pamapombi esimbi kune akasiyana maapplication anogona kusiyana.

3. Kufanana kwegalvanized layer
Yemhando yepamusoro galvanized layer ndeye yunifomu mukugadzirwa, hapana kuvuza uye hapana post plating kukuvara.

Hapana tsvuku tsvuku inowanikwa mushure mekuyedzwa nemhangura sulfate mhinduro, ichiratidza kusadonha kana kukuvadzwa kwemashure.

Iyi ndiyo chiyero chemhando yepamusoro galvanized fittings kuti ive nechokwadi chekushanda kwakanaka uye chitarisiko.

4. Kunamatira kwakasimba kwegalvanized layer
Kusungirirwa kwechigadziko chemarara chiratidzo chakakosha chehutano hwepombi yesimbi, iyo inoratidzira chiyero chekusimba kwekusanganiswa pakati pechigadziko chemarara uye pombi yesimbi.

Iyo pombi yesimbi ichaita musanganiswa we zinc uye iron ine galvanizing solution mushure mekuita kwekunyudza kugeza, uye kunamatira kwezinc layer kunogona kukwidziridzwa nesainzi uye chaiyo galvanizing process.

Kana iyo zinc layer isingabvi nyore kana yakabatwa nerubber mallet, inoratidza kunamatira kwakanaka.
