Ɔhyew-Dip Galvanizing a ɛyɛ hyew

Galvanized steel pipe yɛ dade paipu bi a wɔde zinc a ɛbɔ ho ban akata so. Zinc a wɔde kata so no yɛ adwuma sɛ honam fam akwanside ne afɔrebɔ anode, a ɛkyerɛ sɛ sɛ wɔsɛe ade a wɔde kata so no mpo a, zinc a atwa ho ahyia no di kan sɛe de bɔ dade a ɛwɔ ase no ho ban fi oxidation ho. Eyi ma paipu a wɔde galvanized ayɛ no kyɛ kɛse wɔ mmeae a ɛhɔ yɛ nwini anaasɛ ɛhɔ yɛ hyew.
Akwan abien na wɔtaa fa so de galvanizing yɛ:

• Ɛlektrɔnik-galvanizing– Zinc layer a ɛyɛ tratraa, ne soro yɛ torotoro, adhesion pa, nanso ɛko tia corrosion a ɛba fam koraa.
• Nsuo a ɛyɛ hyew-dip galvanizing (HDG) .– Wɔde dade paipu a wɔatew ho no hyɛ zinc a ayɛ hyew mu wɔ 450–500℃, na ɛyɛ zinc-dade a wɔde afrafra a wɔde dade abɔ dade no ho ne zinc a ɛho tew a ɛwɔ soro. Nneɛma a wɔde kata so no mu duru betumi afi 35 μm kosi 650 μm, na ɛde ahoɔden a ɛkorɔn a ɛko tia nsɛe ne ɔsom nkwa ma sɛ wɔde toto electro-galvanizing ho a.

Esiane sɛ zinc a ɛyɛ den, ɛyɛ pɛ, na ɛka bom denneennen nti, wɔde dade paipu a ɛyɛ hyew-dip galvanized di dwuma kɛse wɔ nsu a wɔde ma, gas kyekyɛ, petrochemical adwumayɛbea ahorow, adansi, awɛmfo akwan, ne abɔnten adan mu, na ɛma ahobammɔ ano aduru a ɛho nhia na ɛkyɛ{1}}.

• ASTM A123 na ɛwɔ hɔ– Zinc (Hot-Dip Galvanized) Nneɛma a Wɔde Kata Dade ne Dade Nneɛma So
• ASTM A53 (Galvanized Ɔkwan a Wɔfa so Yɛ) .– Seamless na welded galvanized dade paipu
• BS 1387 na ɛwɔ hɔ– Hot-dip galvanized pipes ma nsuo, gas, ne nsuo a ɛyɛ hyew
• GB/T 3091 na ɛwɔ hɔ– Welded galvanized dadeɛ paipu ma low-nhyɛso nsuo akwantuo

• Akwanside Ho Ahobammɔ– Zinc a wɔde kata so no tew dade fi nsu ne oxygen ho.
• Katodfo Ahobammɔ– Zinc corrodes preferentially, bɔ dade a ɛda adi ho ban wɔ nsensanee anaa anoano.
• Alloy Layer Nkyekyɛm– Zinc-dade a wɔde afrafra layers ma adhesion a eye kyɛn so na ɛko tia peeling anaasɛ flaking.

• Ɔsom Nkwa Ntrɛwmu– Wɔ wim tebea a ɛfata mu no, galvanized pipes tumi di mfe 30–50; wɔ mfiridwuma anaa mpoano mmeae a, mfe 15–20 ahobammɔ yɛ nea ɛtaa ba.
• Nsɛm a Wɔakata So a Edi Mu– Ɛma ahobanbɔ a ɛyɛ pɛ wɔ paipu no nyinaa so, a welds, ntwea so, ne mmeae a ɛyɛ den-to{1}}du hɔ ka ho.
• Ka-Ɛyɛ nea etu mpɔn– Pɛnko-bere galvanizing ma mfe du du pii ahobammɔ, ɛtew nsiesie ne repaint ka so wɔ ɔsom nkwa nna mu.
• Nteaseɛ a Ɛkorɔn– metallurgical zinc-dade alloy layer no yɛ kɛse a ɛko tia abrasion ne mfiri nkɛntɛnso bere a di dwuma, po so hyɛn, ne installation.
• Eco-Adamfofa– Zinc yɛ nea wotumi san de di dwuma, na hot-dip galvanizing no nya nneɛma a atwa yɛn ho ahyia so nkɛntɛnso a ɛba fam sɛ wɔde toto mfoniniyɛ nhyehyɛe pii ho a.
• Nhwehwɛmu a Ɛnyɛ Den– Coating thickness ne surface quality betumi ayɛ mmerɛw sɛ wobɛhwɛ denam aniwa nhwehwɛmu anaasɛ thickness gauges.

• Municipal Nnwuma a Wɔyɛ: Nsuo a wɔde ma, gas nhama, nsuo a ɛkɔ nsuo mu
• Adansi Nnwuma: Scaffolding, guardrails, adan a wɔde gyina so
• Ahoɔden Dwumadibea: Petrochemical, abɔde mu mframa, nsu a ɛyɛ hyew a wɔkyekyɛ
• Nneɛma a Wɔde Yɛ Adwuma & Transport: Bridge guardrails, kwan so ban, akwan akɛse so adan
• Kuadwuma & Nnwumayɛbea: Nsuo a wɔde gugu nnɔbaeɛ so, nneɛma a wɔde siesie nneɛma, banbɔ

Wɔ Octal Pipe no, wɔyɛ hot-dip galvanized pipes wɔ QA/QC nhyehyɛe a ɛyɛ katee ase:

• Coating thickness sɔhwɛ (μm anaa g/m2) sɛnea ASTM/BS/GB gyinapɛn ahorow te
• Adhesion, uniformity, ne nkyene a wɔde petepete so sɔhwɛ
• Nsusuwii a edi mũ ne aniwa so de hwɛ hu sɛ sintɔ-awie a enni mu
• Flexible supply a ɛwɔ dade grades, diameters, ne tenten ahorow pii
• Nwoma a ɛyɛ papa ne traceability a edi mũ ma adwuma no gye tom

• Kwan: Wɔde gu zinc a wɔayam mu wɔ digrii 450–500 mu
• Zinc a Wɔde Kata So: 35–650 μm
• Nneɛma akɛse: 1⁄2′′ – 20′′ (DN15 – DN500) .
• Gyinapɛn ahorow: ASTM A123, ASTM A53, BS 1387, GB/T 3091. Ɔkwan a wɔfa so yɛ aduru a ɛma obi nya apɔwmuden
• Nnwuma a Wɔde Di Dwuma: Nsu, gas, adansi, ahoɔden, nneɛma a wɔde yɛ adwuma
