海上输油漂浮胶管的研制

Development of Offshore Floating Oil Hose

介绍海上输油漂浮胶管的研制。主体材料采用丁腈橡胶、氯丁橡胶、高强力聚酯浸胶帘布、高强力钢丝、闭孔聚乙烯泡沫板及锻造法兰接头。产品主要由内层胶、增强层、外层胶、漂浮层、外覆层及两端法兰组成。生产工艺采用两次成型和硫化,第1次成型硫化的是胶管的内层胶、增强层和外层胶,第2次成型硫化的是胶管的漂浮层和外覆层。胶管的耐压强度、最小拉伸力、漂浮能力及成品性能均达到了设计和相关标准要求。

The development of offshore floating oil hose was introduced. NR, CR, high tenacity dipped polyester cord, high tensile steel wire, closed cell PE foam board and forged flange were used as main materials. The hose consisted of inner layer, reinforcement layer, outer layer, floating layer, coating layer and flange ends. Two-stage molding and curing processes were designed. In the first stage the inner layer, reinforcement layer and outer layer were molded and cured. In the second stage the floating layer and coating layer were added and cured. The experimental test results showed that the hydrostatic strength, the minimum tensile force and floatability of the hose met the requirements of de- sign and corresponding standards.
