Manufacturing characteristics of packaging steel strip staggered pressure vessel
Compared with other structural types of high pressure vessels, the production efficiency of steel strip staggered pressure vessels is significantly improved, and the manufacturing cost is greatly reduced. The reasons are as follows:
1) The inner cylinder only occupies 1/4-1/6 of the total thickness of the container, and the manufacturing process is greatly simplified. Only ordinary thickness (about 40mm) steel plate can be used to manufacture large-scale high-pressure thick-walled (about 200mm) containers The need to avoid heavy dumping of factory buildings and overhead cranes. This is equivalent to making a manufacturing plant's manufacturing capacity (such as coiling, lifting and flaw detection capabilities), which can be increased by about five times without changing other conditions.
2) Most of the raw materials used are hot-rolled flat steel strips that are easy to roll and low-cost. The size is (4-8)mm*(80-120)mm, which is a narrow and thin section material, regardless of the diameter of the vessel The size and wall thickness of the vessel are all wound with this kind of steel belt.
3) The winding layer is only required to be tight and not required to be 'engaged' like the channel steel belt. Not only the thickness of the winding layer can be thicker than that of the groove winding container, but also the precision of the spiral groove of the inner cylinder is completely avoided. Processing.
4) Most of the thickness of the container is composed of the winding layer, thus reducing a lot of welding, flaw detection and heat treatment workload, especially avoiding thick girth welds and overall heat treatment, the consumption of welding rods, electric power and perspective film The hairline can be reduced by about 80%.
5) The winding of the steel belt can be completed on the simple winding device, and equipped with appropriate tools for welding, grinding and pressing the steel belt, it is not only easier to ensure the winding quality of the steel belt, but also the winding quality of the steel belt. Higher efficiency. The manufacturing process of the container is basically the process of making the inner cylinder and winding the steel belt; after the steel belt is wound, the container is basically completed, with few procedures and short cycle.
Industrial production practice shows that, compared with the current internationally recognized more advanced thick plate coil welding and two-layer hot-sleeve vessels, the production efficiency of steel strip staggered pressure vessels can be more than doubled, and the cost can be reduced. 30%-50%, the economic benefits are very significant.
