Pickling and Passivation process removes free iron contamination left behind on the surface of the stainless steel from machining and fabricating. These contaminants are potential corrosion sites that result in premature corrosion and ultimately result in deterioration of the component if not removed.In addition, the passivation process facilitates the formation of a thin, transparent oxide film that protects the stainless steel from selective oxidation ( corrosion ).

The failure of stainless steel components due to corrosion can reach catastrophic proportions. The cost in time, materials, rectification and lost production can be tremendous. If passivation is not carried out stainless steel can rust due to surface free iron, and since chlorides are also often absorbed from the atmosphere, some ferric chloride will be produced. Prolonged contact with ferric chloride will eventually initiate pitting and crevice corrosion on the stainless steel surface. Proper passivation will assist in the optimal restoration of the chrome oxide passive layer.

VK Jelly - Pickling Paste / Gel for Stainless Steel
VK ® Jelly ® ( Gel / Paste form ) which is used to clean weld seams and surrounding areas and is applied with brush. It is used to remove heavy scales, discolouration, annealing colours, rust particles near weld and welding affected area by heat without grinding or wire brushing or buffing.

Coverage : Approx. 100 meters of running weld seam / kg of VK Jelly

VK Spray - Stainless Steel Pickling Spray Gel / Paste
VK ® Spray is used to clean large stainless steel surface areas with plastic spray pump or pressurised spray bottle. It simultaneously removes annealing colours, ferritic contamination & weld burns. 

VK Spray is safe & easy to use for cleaning of large equipments like S.S. vessels, dryers, agitators, dairy machinery, fermentators, internals as well as externals of pipes by pressurised spray bottle or pump.

Coverage / kg : Approx. 40 sq. ft.

VK Picking Dip Liquid
VK® Dip is used for immersion (dipping) application & non-reachable areas of Stainless Steel ( S.S. ) components like internal & external of pipes, wire rolls, internal recessed areas of machinery etc. Heavy parts are dipped in a huge tank with the help of a chain pully. 

For cleaning & descaling of pipelines, VK Dip is circulated inside pipelines with the help of pump.

Coverage / kg :  Approx. 40 sq. ft.

VK Pass - 1 - Stainless Steel Passivation
VK® Passivation should be used after the application of VK Jelly, VK Spray or VK Dip as it is a must to passivate S.S. surface after pickling. VK Passivation products helps in the formation of a thin passive film on Stainless Steel surface which will protect it from further corrosion and contamination.

There are TWO types of passivation products depending on the end use of S.S. equipments / pipelines / parts.

VK Pass-1 is used for general industrial purpose S.S. equipments & pipings to be used in industries like chemical, paper etc. non-hygenic industries.

Coverage / kg : Approx. 40 sq. ft.

Silicone free - hence no further painting related problems due to Silicone
Grinding & Chipping - Time consuming & Labourious process - NOT required to remove spatters
Slags are easily removed
Cleaning cost is drastically reduced - around 75%
Increase productivity - by 10%
Increase in welder's efficiency - by 25%
Gives dense & clean weld joint
Gaseous & non-metallic inclusions are minimized
Spatters removes gently – maintaining smooth parent surface
Depth of penetration is increased
Acts as a temporary rust preventive (hence useful in avoiding V-groove flash rusting & hence discards re-grinding of V-groove before welding )

Features :

Non Toxic
Non Flammable
Odorless
Silicon Free
Does not cause porosity 

Application Procedure :

SpatFree TM – Nozzle creates an Anti-Spatter film on welding gun nozzles Cool the Nozzle gun and remove the impurities Remove spatters around the contact tip and inside the nozzle.

Dip gun nozzle in to SpatFree TM – Nozzle and start work operations.
Brush onto positioners and fixtures. Avoid build up of SpatFree TM – Nozzle in the diffuser by storing the torch in a downward direction when not in use.

Packing : 300 gm bottle and 4 kg jar

Caution : Avoid contact with eyes as the material is slightly discomforting to the eyes. Avoid prolonged skin contact as it may cause drying of the skin. Use in a well ventilated area, however, SpatFree TM – Nozzzle is not normally a hazard due to the non-volatile nature of the product.

Large structural painting jobs in various heavy engineering industries and projects especially in coastal areas involve the cumbersome rust removal by sand/shot blasting, wire brushing or mechanical grinding etc., prior to painting.

Rustocon is a single pack ready to use solution which on application converts the Rust and acts as a coating preventing further corrosion and also acts as an ideal base for painting. Rustocon prevents the steel from further rusting for a reasonable period of time without any paint coat on it. ( around 2 -3 months stored in room )

Rustocon reacts with all the layers & forms a stable non-reactive complex organo-metallic surface having BLUISH-BLACK COLOUR. It stops the migration of ions, preventing the electro-chemical corrosion process and hence prolonging the life of paint system which result in considerable savings.

Electropolishing chemical & plant which gives mirror bright Stainless Steel metal surface without buffing.

Electropolishing is a reversal electrolysis process. Material from the surface of work piece is removed uniformly leaving a bright and smooth surface finish. Surface of the components is enhanced by treating with given solution and applying appropriate electrical current.

Features :

1. Electropolished surfaces are chemically passive, free from burrs and microscopic cracks.
2. This process gives improved corrosion resistance and durability.
3. This process giving smooth effect reduces friction and wear of two different forms of materials.
4. It also improves conductivity.
5. Electropolished components are easy to clean and it helps reducing bacterial growth.  
6. It is also used for exposing built in material or manufacturing faults.  
7. Compatibility for welding, soldering and to achieve high vacuum is assured.
