Chigadzirwa Nhanganyaya

Nhanganyaya – Chii chinonzi Galvanized Pipe & Chii chinopisa-Dip Gal

Galvanized steel pipe imhando yepombi yesimbi yakafukidzwa nechidziviriro chezinc pamusoro payo. Iyo zinc coating inoshanda zvese sechivharo chemuviri uye sechibairo anode, zvichireva kuti kunyangwe iyo yekupfekedza yakakwenya, iyo zinc yakatenderedza inotanga corrodes kudzivirira simbi yepasi kubva kune oxidation. Izvi zvinoita kuti mapaipi ane galvanized arambe akasimba munzvimbo dzakanyorova kana dzinoora.
Pane nzira mbiri dzakajairika dzegalvanizing:

Electro{0}}galvanizing-Yatete zinc layer, yakatsetseka pamusoro, yakanaka kunamatira, asi yakaderera corrosion resistance.
Kupisa-dip galvanizing (HDG)– Pombi yesimbi yakacheneswa inonyudzwa muzinc yakanyungudutswa pa450–500℃, ichiita zinc-iron alloy layer inobatanidzwa nesimbi uye pamusoro pezinc chaiyo. Ukobvu hwekuvharisa hunogona kubva pa35 μm kusvika pa650 μm, zvichipa kusaita ngura kwepamusoro uye hupenyu hwesevhisi zvichienzaniswa neelectro-galvanizing.

Nekuda kwekukora kwayo, yunifomu, uye yakasungirirwa zvakasimba zinc layer, inopisa-dip galvanized steel pipe inoshandiswa zvakanyanya mukupa mvura, kugovera gasi, petrochemical properties, kuvaka, magadhi, uye zvivakwa zvekunze, zvichipa mhinduro ine mari uye yakareba-yenguva refu.

Zviyero Zvinoenderana Nezvakatemwa

ASTM A123-Zinc (Kupisa-Dip Galvanized) Coatings paSimbi neSimbi Zvigadzirwa
ASTM A53 (Galvanized Option)– Seamless uye welded galvanized simbi pombi
BS 1387-Kupisa-kunyudza mapaipi emvura, gasi, uye chiutsi
GB/T 3091– Mapombi esimbi akaiswa galvanized for low{0}}pressure fluid transport

Kugadzira / Coating process

Danho	Tsanangudzo
a. Kugadzirira Kwepamusoro	Mapombi esimbi anocheneswa, akacheneswa (asidhi yakacheneswa) kubvisa chigayo uye ngura; flux inogona kuiswa kudzivirira oxidation isati yaita galvanizing.
b. Kunyudzwa muMolten Zinc	Mapaipi akanyikwa muyakanyungudutswa zinc yekugezera paanenge 450-500 dhigirii, zvichibvumira kuita kwesimbi kuumba alloy layer uye yekunze yakachena zinc layer.
c. Kudzima / Kutonhodza	Mapaipi akabviswa, zinc yakawandisa inobvumirwa kudonha, yobva yadzimwa kana mhepo yakatonhodzwa kuti isimbise kupfekedza uye kuderedza kukanganisa.
d. Post-Kurapwa / Kupedza	Dzimwe nguva kuchenesa slag, kukuya spangles kana zvichidikanwa, kuve nechokwadi kunyange chitarisiko; Optional passivation kana kupfekedza pamusoro pekuvheneka kuitira basa chairo.
e. Kuongorora & Kugadzirisa	Tarisa uone ukobvu hwemabhachi, -zvisina kukanganisa (mazororo), kunamira, kufanana pamusoro pemuviri, mawedhi neshinda.

Dziviriro Mechanism

Barrier Protection-Zinc yekuputira inoparadzanisa simbi kubva munyoro uye oksijeni.
Cathodic Protection-Zinc corrodes zviri nani, inodzivirira simbi yakafumurwa pamakwara kana kumicheto.
Alloy Layer Bonding-Zinc-iron alloy layers inopa kunamira kwakanaka uye kusada kupepeta kana kupeuka.

Zvakanakira (Zvakawedzerwa)

Hupenyu Hwebasa Hwakawedzerwa- Mumamiriro ekunze emuchadenga, mapaipi ane galvanized anogona kugara makore 30-50; munzvimbo dzeindasitiri kana dzemahombekombe, 15-20 makore ekudzivirira akajairika.
Complete Coverage-Inopa dziviriro yakafanana pamusoro pepombi yose, kusanganisira mawedhi, makona, uye zvakaoma-kusvika{1}}nzvimbo.
Mutengo-Kushanda-Kamwe-kuvheneka kunopa makumi emakore edziviriro, kuderedza kugadziridza uye kupenda patsva mukati mehupenyu hwesevhisi.
High Durability– Metallurgical zinc-iron alloy layer inoshingirira kuabrasion uye kukanganiswa kwemuchina panguva yekubata, kutumira, nekuisa.
Eco{{0}Hushamwari– Zinc inogona kushandiswa zvakare, uye kupisa-dip galvanizing kune kushomeka kwemamiriro ekunze kana zvichienzaniswa nependi yakawanda.
Easy Inspection-Kupfeka ukobvu uye hunhu hwepamusoro hunogona kusimbiswa zviri nyore nekutarisa kwekuona kana mageji ukobvu.
