Coiling Frame for Site-built Steel Tanks Fabrication:
EuroTankWorks JSC is one of the few storage tanks and silos manufacturers in the world equipped with the special coiling machine. This enables to produce coiled panels of the wall, bottom and roof of the tank with the use of automated double-welding.
First, a map of the panel is collected on the upper tier of the coiling frame. Then the joints are welded by the automatic welding tractor. Then, through the auxiliary coil, the panel stretches to the lower tier, after which the joints are welded from the back side.
The quality control is then made: all welded joints are visually inspected and checked by an X-ray. For the work of the Non-destructive Control Laboratory under the lower tier of the coiling machine, staff access is specially provided. As a matter of fact, only the two-tiered coiling frame allows to really carry out quality control of welded joints in accordance with the requirements of Regulatory documents.
The quality of rolled tank structures, produced at the special facility, is sufficiently higher than that of the plates, “rolled” on the floor by the hauling winches. Our enterprise guarantees the exact geometric parameters, lack of deformation and ideal welding joints.
Technical equipment of the our steel tanks fabrication facility:
Our company is one of the storage tanks manufacturers , having sufficient material and technical possibilities for appropriate metal-roll preparation, which ensures high quality of all tank elements.
Since a tank is not just a set of walls and bottom, but also manway plates, fitting pipes, flanges, footpaths and other technological elements, the quality of the final unit is greatly dependent on the accuracy of each element’s production.
Our enterprise has fully equipped mechanical metal processing shop, highly-accurate scarfing machines, plate-bending and plate-flattening equipment, metal turning lathes and drilling machines.
