Custom Tanks Fabrication for Papermaking: A Project Case Study

The papermaking industry relies heavily on the efficient storage and processing of various chemicals and liquids. To meet the specific requirements of this industry, custom tank fabrication plays a crucial role. These tailor-made tanks ensure the safe and efficient storage of raw materials, chemicals, and by-products, facilitating the smooth operation of paper mills. Recently, we undertake a metal fabrication project of manufacturing custom tanks for a papermaking customer.

Project Overview

In this project, the fabrication involved the construction of over 120 tanks, comprising 10 large pressure tanks and more than 110 sets of general tank structures. These tanks were designed to store and process different liquids and chemicals used in the papermaking process. The scope of the fabrication process encompassed cutting, plate rolling, steel cone fabrication, tank head fabrication, bending, welding, non-destructive testing (NDT), sandblasting, painting, pickling, and other crucial procedures.

Fabrication Process

The custom tank fabrication process commenced with the precise cutting of steel plates according to the required dimensions and specifications. Skilled fabricators then utilized plate rolling techniques to shape the plates into cylindrical forms, which served as the main body of the tanks. Subsequently, the fabrication team employed advanced techniques to create steel cones, which were seamlessly integrated with the cylindrical body to optimize structural integrity.

To ensure a secure and tight seal, tank heads were pressed and welded onto the tanks' ends, forming a closed and robust container. The welding process employed in the fabrication phase adhered to industry-standard procedures, such as TIG (Tungsten Inert Gas) welding, which guarantees high-quality welds and prevents leakage.

After the fabrication process, NDT techniques, including ultrasonic testing and radiographic inspection, were employed to detect any potential defects or irregularities. This stringent quality control ensured that the tanks met the highest standards of safety and reliability.

The final steps involved sandblasting to remove any surface impurities, followed by protective painting to enhance the tanks' resistance to corrosion. Pickling, a process of chemical cleaning, was also employed to eliminate any residual impurities that could potentially contaminate the stored liquids.

Challenges Faced

This project presented several unique challenges. The primary challenge was the large quantity of tanks required, coupled with the diverse specifications for each tank. The fabrication team had to meticulously manage and execute the production process to ensure accuracy and consistency across the entire project. Furthermore, the tight delivery schedule added to the complexity, demanding efficient coordination and adherence to strict timelines.

How Metal Fabrication Companies Benefit Papermaking?

Metal fabrication companies play a pivotal role in supporting the papermaking industry through custom tank fabrication. By designing and constructing tanks tailored to the specific needs of paper mills, these companies ensure seamless operations and enhanced productivity. Custom tanks enable the safe and efficient storage of various chemicals, allowing paper manufacturers to optimize their production processes while ensuring worker safety.

Moreover, metal fabrication companies contribute to the longevity and durability of the tanks. The precise construction techniques, combined with the use of high-quality materials, result in tanks that can withstand harsh operating conditions and resist corrosion. These robust tanks minimize the risk of leaks, contamination, and downtime, ensuring uninterrupted paper production.
