Repeatedly Dehiscence and Residual Stress of Liquefied Gas Spherical Vessel

Abstract:

Comprehensive residual stress of a 1500m3 liquefied petroleum gas spherical vessel was measured and analyzed after many cracks arised. The results show that the general residual stress was at a high level in the field with cracks as well as the field without cracks. Furthermore, the measurements were taken at the same place to evaluate the effect of the heat treatment after this spherical vessel was re-welded and the integral heat treatment was performed. Meanwhile, the measurement to the stress in the vertical direction with X-Ray was finished after a set of special treatments in the outfield.
