| 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 design and corresponding standards. |
