D-type ultra-high pressure large gap sealing element

Mainly used for pressure testing machines to test the pressure resistance of steel pipes. In a non-working state, there is a certain gap between the sealing element and the sealed surface; during operation, the sealing element is pressed against the outer periphery and tightly contacts the sealed surface to achieve sealing, conducting the water pressure test.

Performance and Purpose

The sealing component is made up of a polyurethane sealing ring and fan-shaped supporters. It is mainly used in the pressure test of steel pipe by hydro-static testing machine. In the non-working state between the sealing ring and surface of steel pipe exists gap. When hydraulic liquid is applied to the external of the sealing ring, the ring is pressed to enclose the surface of steel pipe firmly, and then the pressure testing can be performed. It is applicable to the pressure testing of casing, tubing, natural gas pipe and other steel pipe. It has also been used in leak inspection of the steel pipe, connection, welded joints and sealing for the high pressure valve.

D型超高压大间隙密封元件是由密封圈和扇形支撑块组成的密封元件。主要用于水压试验机对钢管的耐压试验。在非工作状态下，密封元件与被密封面之间有一定的间隙；工作时，密封元件受外周加压后与被密封面紧密接触实现密封，进行水压试验。本产品适用于水压试验机对套管、油管、天然气输送管道等钢管进行水压试验，也可用于钢管、管接头、焊口检漏及超高压阀门密封等。

Advantage

1. Lip Optimization: under peripheral pressure, the lip and groove surface fit more closely, and the higher the pressure, the better the lip sealing.

唇边优化，在外周受压下，是唇边与沟槽面贴合更紧密，压力越大唇边密封越好

2. The fan-shaped supporters, in the premise of increasing the strength of the sealing ring, can shrink and expand in radial direction with the sealing ring.

专业设计扇形支撑块，在增加密封圈强度的前提下，能随密封圈在径向方向收缩、胀大
