In this article, it expatiated the sealing principle of steel pipe hydrostatic testing machine sealing surface, and analyzed two main factors caused leak, including the gap existing sealing pair and the differential pressure existing in both sides of sealing pair. It pointed out that the valve sealing surface should be designed according to process conditions, fluid performance, working temperature, pressure and valve size and other technical parameters. The calculation method for sealing surface design parameters was provided, a conclusion of the influence of sealing surface width and sealing force on sealing performance was obtained through calculation. Simultaneously, it analyzed the relevant factors for affecting sealing performance of sealing surface in the case of water medium.
