Liquid tanks are used for the transportation of liquid food, fuel, and other substances. The tanks are manufactured using a single piece of steel plate to prevent the use of circumferential welds. It has various shapes (circular, elliptical, and multi center), and the liquid tank car/train liquid tank adopts CNC bending steel or aluminum plates, with thicknesses ranging from 3mm to 15mm and widths ranging from 3 meters, 6 meters, 8 meters, or 10 meters to meet different applications. Longxu Heavy Industries provides a complete set of spherical head production lines, including presses, robotic arms, and spinning machines; These devices are widely used in the manufacturing of liquid tanks.
