The Combined Application of Nondestructive Testing Technology in the Periodic Inspection of Spherical Tank

Spherical storage tank is widely used to carry high pressure and contain inflammable explosive or poisonous and harmful media. Its regular inspection is directly related to its safe operation and is very important. Two case studies were performed in relation with the periodic inspection of spherical tank in this paper, so as to expound the optimization of the combination of nondestructive testing technology in application of periodic inspection, to improve the level of inspection and to ensure equipment safety.
