Tok i go pas – Wanem samting em Galvanized Pipe & Wanem samting em Hot-Dip Gal

Galvanized steel paip em i wanpela kain ain paip we i gat wanpela 'zinc' antap long en. Dispela 'zinc coating' i save wok olsem wanpela 'physical barrier' na olsem wanpela 'sacrificial anode', dispela i min olsem maski ol i skrapim dispela 'coating', 'zinc' i stap klostu i save bagarap pastaim long lukautim 'underlying steel' long 'oxidation'. Dispela i mekim ol paip we i gat 'galvanized' i stap longpela taim moa long ol ples we i gat wara o i save bagarap.
I gat tupela rot bilong 'galvanizing':

Electro-galvanizing– Tinpela 'zinc layer', gutpela pes, gutpela 'adhesion', tasol i no inap long bagarap.
Hot-dip galvanising (HDG)– Ol i putim ain paip we ol i klinim pinis insait long 'molten zinc' long 450-500 digri, na dispela i kamapim wanpela 'zinc-ain aloi leia we i pas long ain na wanpela top leia bilong 'pure zinc'. Tiknes bilong 'coating' inap long 35 μm i go inap 650 μm, na i save givim gutpela 'corrosion resistance' na 'service life' taim yumi skelim wantaim 'electro-galvanizing.

Bikos em i gat tikpela, wankain, na strongpela 'zinc layer', ol i save yusim hot-dip galvanised steel paip long wara saplai, ges distribusen, petrokemikel fasiliti, konstraksen, 'guardrails', na ol ausait straksa, na dispela i givim wanpela ekonomik na longpela taim proteksen solusen.

Ol Standet na Spesifikasen we i stret

ASTM A123– Zinc (Hot-Dip Galvanized) Koting long ol Ain na Stil Prodak
ASTM A53 (Galvanized Option)– Paip bilong ain we i no gat rop na i weldim
BS 1387– Hot-dip ol paip bilong wara, ges, na stim
GB/T 3091– Ol paip ol i wokim long ain we ol i weldim bilong karim wara i go i kam long liklik presa

Proses bilong wokim / kotim

Step	Diskripsen
a. Redim pes	Ol i save rausim gris long ol paip ain, klinim, putim pik (klinim long asid) bilong rausim ol 'mill scale' na 'rust'; ol i ken putim 'flux' long stopim 'oxidation' pastaim long 'galvanizing'.
b. Putim insait long Molten Zinc	Ol i save putim ol paip insait long 'molten zinc bath' long 450-500 digri, na dispela i larim ol 'metallurgical reaction' long kamapim ol 'alloy layers' na 'outer pure zinc layer'.
c. Kukim / Kulim	Ol i rausim ol paip, larim planti 'zinc' i go aut, na bihain ol i kilim o mekim i kol long win bilong mekim 'coating' i kamap strong na daunim ol bagarap.
d. Post-Tritmen / Pinisim	Sampela taim klinim ol 'slag', grindim ol 'spangles' sapos i gat nid, na mekim ol i luk wankain; opsenel pasivesen o koting antap long galvanising bilong mekim wanpela sevis.
e. Sekim na stretim	Sekim sapos 'coating' i tik, ol samting we i no inap bagarapim (ol holide), 'adhesion', 'uniformity' antap long bodi, ol 'weld' na 'thread'.

Proteksen Mekanisme

Proteksen bilong banis– Zinc koting i save rausim ain long wara na oksijen.
Katolik Proteksen– Zinc i save bagarap gut, na i save lukautim ain we i stap ples klia long ol mak o arere.
Alloy Layer Bonding– Ol 'zinc-'ain aloi leia i save givim gutpela 'adhesion' na i no inap bruk o bruk.

Ol bikpela gutpela samting (I go bikpela)

Laip bilong sevis i go longpela– Long ol nomol kondisen bilong win, ol paip we i gat 'galvanized' inap long stap inap 30-50 yia; long ol indastrial o nambis envairomen, 15-20 yia bilong lukautim em i save kamap.
Komplit Kavrej– I givim wankain proteksen long olgeta paip, wantaim ol weld, kona, na ol hap we i hat long kisim.
Kost-Ifektiv– Wanpela taim bilong 'galvanizing' i save givim planti yia bilong lukautim, na i save daunim ol kos bilong lukautim na penim gen long sevis laip.
Bikpela strong– Metallurgical zinc-ain aloi leia em i no inap bruk na bagarap long masin taim ol i holim, salim, na putim.
Eco-Frenli– Zinc em i samting we ol i ken yusim gen, na hot-dip galvanising i no gat bikpela hevi long envairomen taim yumi skelim wantaim planti peinting sistem.
Isi Inspeksen– Tiknes bilong 'coating' na kwaliti bilong pes bilong en i ken kamap isi long lukluk long en o long ol 'thickness gauges'.
