Chemical Pretreatment Tanks

We have been providing Pretreatment Tanks since 1962 and offer a service guarantee and replacement warranty. Environmental and safety issues need to be considered during the cleaning, painting and curing of products. In the paint or coating industry, there will be disposal of solid waste in the form of heavy metals, pigments and liquid waste containing some solvents, burning fuel gases and solvent vapors, where water will be the carrying medium. The cleaning, painting and curing process of the product includes industrial tanks, pretreatment tanks, Pickling Tank, galvanizing tanks and galvanizing baths.

Galvanized pretreatment

The pretreatment area is a fundamental part of the hot dip galvanizing facility. In the pretreatment area, in addition to the appropriate Pickling Tank, there are Degreasing, Rinsing, Fluxing and Pickling Tanks. all operations related to the chemical preparation of the steel surface to be galvanized are performed in the Pretreatment Tanks. Traditionally, these steps of surface treatment have not been the central focus of galvanizing plants, mainly due to the inherent stability of the entire process.

Annuo has developed and introduced to the market an advanced and up-to-date pretreatment management concept, which is an important part of the company's broad mission to promote a forward-looking hot dip galvanizing culture. Customers who have embraced this innovative approach have experimented with the efficiency of Annuo's pretreatment concept. The main advantages for customers who have adopted our automated pretreatment management system are:

Chemical stability of the process, resulting in an unprecedented increase in average product quality.
Reduction in the number of operators required in the pretreatment area.
Full compliance with the most stringent environmental regulations.
Complete capture and reduction of acid fumes, thus protecting the building structure.

Advantages of PP pickling tank:

1. The outside of the tanks are made of high strength steel frame, with PP plate inside.
2. Due to the high strength of the steel frame and thick PP plate, these tanks are very suitable for Galvanizing requirements.
3. Since the steel frame is not in contact with the acid, so the tanks are good anti-corrosion. In addition, in case of leakage, it is very easy to find the leak point quickly, and easy to repair.

Advantages of granite pickling tank:

1. Convenient in manufacturing and construction, reliable quality and performance, strong durability, high functional.
2. Flexible setting, easy to maintain.
3. Strong acid and alkali resistance, crash resistant.
