Hot Dip Galvanizing Process

R.K. Engineering & Galvanizers offers hot deep galvanizing as traditional corrosion protection for steel and metal components. The entire process is done by the skilled professionals of the organization.

We have galvanizing process in high / normal temperature.

Hot Dip Galvanizing Process

1 . Preparing the surface for galvanizing :

Three steps comprise surface preparation for galvanizing: Dirt, paint marks, grease, and oil are examples of organic pollutants that can be removed from the metal surface using a hot alkali solution, mild acidic bath, or biological cleaning bath.

2 . Fluxing :

The metal is submerged in a flux solution after being cleaned. Any leftover oxides are eliminated by fluxing, which also stops new oxides from forming during the galvanizing process. It facilitates zinc's adhesion to the metal surface as well.

3 . Galvanizing bath :

After the metal has been cleaned and fluxed, it is submerged in a bath of molten zinc, which is normally kept at 450°C (850°F). A metallurgical link may be formed between the zinc and the metal thanks to this molten zinc bath.

4 . Withdrawal:

The metal is gradually removed from the zinc bath after submersion to enable any excess zinc to drain out. This procedure guarantees a consistent zinc coating.

5 . Quenching :

In certain circumstances, the galvanized metal is quenched in water or another cooling media to cool it down fast. The final galvanized surface's appearance may be affected by this stage.

6 . Inspection :

The object that has been galvanized is examined for deficiencies or places where the zinc coating could not have bonded correctly. We can deal with these problems if needed.

Features

Corrosion resistance : Hot galvanizing line is used to produce corrosion resistance and smooth layer on the surface of raw pipes after cleaning.

Lowest First Cost : In many cases galvanizing costs less to apply compared to other coatings with short.

Lowest Long Term Cost : Even in case where the initial cost of galvanizing is higher than comparable system, Galvanizing is invariably cheaper in the long run on life cycle cost analysis.

Long Life : The Standard 610 gm / Sqm galvanized coating has a typical life without maintenance of mon environments & 35-50 years in urban & coastal conditions.

Realiability : The galvanizing coating is bonded metallurgically to the base steel so that it becomes part of Coating life & performance are therefore reliable & predictable.

Coating Toughness : A galvaizing coating has unique metallurgical structure which gives out standing mechanical damages in transport, erection & service.

Eliminatin of Maintenance for long periods : The use of galvanizing defers maintenance for coating on steel. Remember maintenance can be extremely expensive when it entails difficult access or located in inaccessible areas.

Automatic Protection for Damaged Areas : Galvanized coating corrode preferentially to steel, protection to small exposed areas of steel through damage to the coating. Unlike organic coatings no to

Complete Protection : Every part of galvanizing article is fully protected, even recess sharp corner other coating applied to a structure can provide the same protection.

Ease of Inspection : Galvanizing coating thickness is controlled automatically by steel thickness & coating mass is assured. Soundness & continuity of coating can be judged by bare eyes.

Mechanical Properties : Galvanizing has no effect on the mechanical properties of commonly gal

Time Saving : Galvanizing is a faster process than painting or epoxy & elimination of site painting subtantial time in site erection or assembly of jobs.
