用嘴唇接触密封

轮 与框架 聚氨酯

性能及用途:1。它由密封圈,扇形支撑块和扇形角度。主要用于钢管的压力测试hydro-static试验机。2。因为它是用来测试钢管的内径,测试时,密封圈会扩展到封闭管道内径来达到密封的目的。3所示。唇优化:在外围的压力下,嘴唇和槽表面适合更密切,和压力越高,越好唇密封。4所示。扇形的支持者,提高密封圈的强度的前提下,可以缩小和扩大在径向密封圈。5。Its test head is smaller than type D or C and production cost is lower as well. It is applicable to the pressure testing of casing, tubing, natural gas pipe and other steel pipe. Working conditions: Working pressure: ≤ 60 M Pa Working temperature: -20℃～+80℃ Working medium: water, emulsion, hydraulic oil Material: Polyurethane
