C型大间隙超高压密封部件它由密封圈、扇形支撑块和扇形角组成。主要用于水压试验机对钢管进行压力试验。2.C型比D型有更多的密封间隙(参考公司原有目录),相同尺寸的密封部件适用于更广泛的钢管范围。3.唇边优化:在周边压力下,唇边与槽面贴合得更紧密,压力越高,唇边密封效果越好。4.扇形支架,在增加密封圈强度的前提下,能随密封圈径向收缩和膨胀。5.适用于套管、油管、天然气管及其它钢管的耐压试验。 It has also been used in leak test of the steel pipe,welded joints and sealing for the ultrahigh pressure valve. Working conditions: Working pressure: ≤ 120 MPa Working temperature: -20℃~+80℃ Working medium: water, emulsion, hydraulic oil Material: Polyurethane
