Arc Carbon Steel Reinforcement Ring Tank Opening Reinforcement Ring Pipeline Reinforcement Ring

Overview:
The reinforcement ring generally adopts an overlapping structure with the vessel wall, and the material is the same as that of the vessel wall. The size of the reinforcement ring can be determined with reference to the standard, or it can be calculated according to the principle of equal area reinforcement. When the thickness of the reinforcing ring exceeds 8mm, the full penetration structure is generally adopted to make it bear the force at the same time as the wall of the vessel, otherwise it will not have the reinforcing effect. For the convenience of welding, the reinforcing ring can be placed on the outer or inner surface of the wall, or symmetrically placed on the inner and outer surfaces, but for the convenience of welding, the reinforcing ring is generally placed on the outside for single-sided reinforcement. In order to check the tightness of the weld, there is a small M10 threaded hole on the reinforcement ring. Compressed air is introduced from here to conduct a weld tightness test. The reinforcement circle is now standardized.

The reinforcing ring has a simple structure, is easy to manufacture, and has a wide range of applications. However, there is a static air gap between the reinforcing ring and the shell, and the heat transfer effect is poor, resulting in a large temperature difference and thermal expansion difference between the two, which is easy to cause temperature stress. When the reinforcing ring is welded to the shell, the rigidity here becomes larger, which has a greater restraint on the cooling shrinkage of the fillet weld, and it is easy to cause cracks at the weld. In particular, high-strength steel has high hardenability, is more sensitive to welding cracks, and is more prone to cracking. Also, because the reinforcing ring and the shell or the connecting metal are not formed as a whole, the fatigue resistance is poor. Therefore, the use range of the reinforcement ring lap welding structure needs to be limited.
