burst pressure

基本解释

The main research results are as follows:(1)Based on strength equivalent method, short-time burst pressure formula of PSP was deduced.
采用力平衡法推导出了这种复合管的短期爆破压力计算公式。
In order to make the calculated burst pressure coincide with actual value, the developed fiber strength value must be determined by the simulation test.
为了使计算的爆破压强与实际结果相符合，纤维发挥强度的选取必须由模拟试验确定。
As shown in the experimental results, its short-time burst pressure at room temperature is increased by 129%, ring stiffness by 19%, and critical buckling pressure by 57% in comparison with PE pipe.
结果表明，与相同规格尺寸的PE管相比，其短期爆破压力、环刚度和临界失稳压力分别提高了129%、19%和57%；

Does this mean a burst is on the cards, or does it suggest selling pressure (both short and closing longs) may exert an influence at a more gradual pace?

爆破压力
The pipes exhibited 4-fold improvement of hoop tensile strength and 70% increase of burst pressure . The formation of fibril structure along hoop direction and elimination of weld-lines resulted in the high hoop strength of the pipes.
争下实现管材的自增强，自增强管材的周向强度提高了4倍，爆破压力提高了70％，管材强度提高的原因是管材中形成了微纤结构；采用芯棒旋转口模挤出管材，可改变熔接痕的结构，在合适的挤出速度和芯棒转速下，甚至可消除熔接痕。
