轮密封

d形环 聚氨酯 对于圆柱体

我。性能和用途:密封组件由聚氨酯密封圈和扇形支座组成。主要用于水压试验机对钢管进行压力试验。在非工作状态下，密封圈与钢管表面之间存在间隙。当液压液作用于密封圈的外部时，将密封圈压紧，牢固地包裹住钢管表面，然后进行压力测试。适用于套管、油管、天然气管及其它钢管的耐压试验。还用于高压阀门的钢管、接头、焊接接头和密封的检漏。2材质:参照GB/T3672.1-2002公差。聚氨酯三世。工作条件:符合API 5CT/ISO11960:2004、GB/T9711.1-1997、GB/T9711.2-1999等标准。 Such as oil well casing or tubing in the oil and natural gas industry.
