Rolling Sheet Metal Welded Cylinder Service for the Chemical Industry

In industrial fabrication, the production of rolled and welded cylinders plays a crucial role, especially in the chemical industry. Recently, our company had the privilege of successfully completing a notable project involving the fabrication of carbon steel plate rolled and welded cylinders for a prominent client in the chemical industry. The project involved the completion of a batch of rolled and welded cylinders, manufactured from Q345R carbon steel plates, boasting a thickness of 30㎜, width of 2500㎜, and diameter reaching an impressive 4000㎜.

The Challenge

Undertaking the rolling of plates with superlative characteristics—extraordinary thickness, exceptional width, large diameter, and single-piece weight of 7.5 tons—posed a considerable challenge. In the face of this unique task, our dedicated technical team engaged in extensive deliberation, thoroughly assessing the production process and potential risks. To ensure the success of the project, a meticulous plan was devised, with a strong emphasis on overcoming the anticipated difficulties and meticulously controlling the quality of each production stage.

Fabrication Process

The fabrication process involved a series of intricate steps to transform raw carbon steel plates into sturdy welded cylinders, meeting the stringent requirements of the chemical industry. Allow us to provide a glimpse into our comprehensive approach:

1. Material Preparation: Q345R carbon steel plates, renowned for their excellent mechanical properties and resistance to corrosion. The chosen plates were carefully inspected for any defects or irregularities before proceeding.
2. Plate Rolling: Employing cutting-edge equipment and leveraging our expertise in plate rolling, we executed the precise shaping of the carbon steel plates. The super-thick and super-wide dimensions demanded utmost precision, which we achieved by applying stringent quality control measures throughout the process.
3. Welding and Cylinder Formation: Our highly skilled welders meticulously joined the rolled plates using advanced welding techniques, ensuring structural integrity and optimal strength. The welding process adhered to industry best practices, ensuring a secure and leak-proof construction. The formed cylinders were subjected to rigorous quality checks to ensure compliance with the highest standards.
4. Rounding, Grouping, and Back Rounding: To finalize the construction, meticulous rounding, grouping, and back rounding processes were performed. These critical steps ensured the seamless integration of individual cylinders into a cohesive unit, providing enhanced stability and reliability.

Through our unwavering commitment to excellence, we successfully executed the challenging project. The quality of our work garnered high praise and recognition from our esteemed customer within the chemical industry. Their satisfaction not only reaffirms our technical capabilities but also reinforces our dedication to delivering superior solutions.
