本文就液化石油气钢瓶的爆破形式和能量计算作一简单介绍。一、爆破形式液化石油气钢瓶发生破坏主要有塑性破坏、脆性破坏和腐蚀破坏三种形式。 1.塑性破坏所谓塑性破坏,就是钢瓶材料受到过高的压力,以至超过了它的屈服极限或抗拉极限,因而使钢瓶产生较大的塑性变形,最后发生破断的一种破坏形式。 In this paper, a brief introduction is made on the blasting form and energy calculation of liquefied petroleum gas cylinders. First, the form of blasting Liquefied petroleum gas cylinder damage occurred mainly plastic damage, brittle failure and corrosion damage in three forms. 1. Plastic damage The so-called plastic damage, is the cylinder material subjected to excessive pressure, and even beyond its yield limit or tensile limit, resulting in a large plastic deformation of the cylinder, the final occurrence of a broken form of destruction.
