Hot Dip Galvanizing in Howrah (1 service providers available)

Fluxing The acid-cleaned steel article is immersed in a flux solution, usually 30% zinc ammonium chloride with wetting agents, maintained at about 65◦C. The flux solution removes the oxide film which forms on the highly reactive steel surface after acid cleaning and prevents further oxidation before galvanising. The work is then dried ready for galvanising.   Galvanising On immersion in the galvanising bath the steel surface is wetted by the molten zinc and reacts to form zinc-iron alloy layers. To allow formation of the metallurgic bond the work remains in the bath until its temperature reaches that of the molten zinc, in the range 445◦C to 465◦C. The work is then withdrawn at a controlled The period of immersion in the galvanising bath varies from several minutes The resulting galvanised coating is tough and durable, comprising relatively pure zinc and zinc-iron alloy layers bonded metallurgically to the underlying steel, completely covering the article externally and internally, providing resistance to corrosion. The fact that hot dipped galvanising provides internal as well as external protection.   Galvanising Facilities NSEPL Galvanizing 9 m long x 1.2m wide x 1.2m deep.NSEPL Galvanizing work 24 hours a day, offering industry leading turnarounds with the majority of work being galvanized within 2 days of receipt.The layout of the galvanizing facilities at Domjur, Howrah have been designed with customers in mind.
