Pickling Process And Pickling Tank Introduction

Pickling is a metal surface treatment that is used for the purpose of removing impurities like stains, rust, or scale from copper, alloy, and other metals. Pickle liquor, which is an acid-based solution is used to eliminate the impurities from the surface. Metal can contain impurities that may affect the quality of the product or further processing of it like plating or painting. 

Pickling is the most preferable method of removing rust and mill from structural shapes, beams, and plates in workshops, keeping the cost of removal budget-friendly. When the process of pickling is done impeccably, this method creates a surface that will have long paint life with various coatings.

There Are Six Main Pickling Methods, Which Includes – 

  • Sulfuric or hydrochloric acid pickling
  • Phosphoric acid pickling
  • Sulfuric acid-sodium dichromate pickling
  • Alkaline pickling 
  • Footner pickling
  • Electrochemical treatment

These are some of the most popular pickling methods and they are used depending on the nature of the rust and scale to be removed, the materials that are used for the manufacturing of the articles, the desired pickled surface, and the cost and availability of pickling material and equipment.

Pickling Tank 

A picking tank is a kind of tank that is used for the process of metal surface treatment containing acid where the metal is immersed in the pickling acid in order to scale off the oxide/rust from the product which is being treated.

How The Pickling Tank Designed? 

  • It is designed as per the standard DVS 2205. 
  • It has good weld joints for making it leakage proof. 
  • It has good abrasion resistant power. 
  • It is made with reinforced steel. 

What Is The Size Of Pickling Tanks?

Small tanks have a capacity of a few hundred liters while the big tanks have a capacity of over 20,000 liters. These tanks are built to the size of metal objects which will be treated in the tank.

What makes Corrotech one of the leading and reliable manufacturers of pretreatment and post-treatment tanks for galvanizing plants?

Corrotech is one of the leading suppliers and manufacturers of Pickling tanks in India and also other types of pre-treatment and post-treatment tanks for galvanized plants.  We use RITA 3 (Roechling Integrated Tank Design), which is a German Software to design the tanks and we adhere to manufacturing practices laid in the DVS (German Welding Society) Technical Codes. Corrotech has achieved a unique ability in FOLD bending the PP sheets providing more durability and strength to the tank. Corrotech strictly adheres to the welding norms laid by the German Welding Society and ensures superior quality tanks. Corrotech is immensely proud to be the company in the world to weld the main body and the end walls of the tank using the “Butt Fusion” technique which gives long life to weld seams which eliminates the risk of tank failure or leakage. At Corrotech, we fabricate the support frame structures using Rectangular Hollow Sections (RHS) and coat them with FRP to resist acid attack. The steel is procured as per IS 4923 – 1997 or any other international standard as per the requirements of the contract. The welds are prepared as per AS 1554 and the weld type is the continuous fillet.

The top features of the tanks manufactured by us are – 

Manufactured using Homopolymer Polypropylene or Copolymer Polypropylene or Fiber Resin Plastic

  • Sheets are welded using German Wegner Welding Machine according to DVS norms which eliminates leakage and ensures a long lifespan.
  • 100% leak proof welding.
  • Tanks have 900C FOLD bending at the bottom corners
  • The raw material is procured from global vendors; Rochling, Germany, Reliance, India, etc
  • Environmentally friendly design.
  • Superior design
  • Lifting arrangement.
