The results indicate that the X70 pipeline steel with acicular ferrite microstructure has high strength, high toughness, low transition temperature and high dynamic tear-resistance.
结果表明，本钢X70管线钢具有高强度、高抗动态撕裂能力、高低温冲击韧性以及低韧脆转变温度。
The silicon and fluorine rubber with high temperature resistance, low compression permanent deformation, and high tear strength properties can meet the water sealing gasket requirements.
采用耐高温、低压缩永久变形、高抗撕裂硅、氟橡胶可以满足该部位需耐高温、耐冷却水的要求。
Hydrolysis: Water and high temperature can change the consistency of certain polyurethanes. Colours change and material crumbles into small pieces. Tensile and tear strength deteriorate.
水解：水和很高的温度可以改变一定的聚氨酯类韧性。颜色改变和原料分成小块，张力和撕力会破坏。
