“…The real measurement of contact width was studied with considering surface roughness and local contact stress have been examined by using numerical analysis and the distribution of contact stress has been clarified. The previous research used a single material SUS304 [6][7][8]. By using elastic design and plastic design mode, it can be denoting the gasket design with 1.5 and 2.5 m flange surface roughness produces no leak, but high clamping load is required.…”

“…As shown in Figure , only the micro‐convex body contacts the seal face between the metal seal element and the closure member before the differential pressure is applied. If the deformation on the seal face is insufficient, two seal faces will not fully contact, which will result in generating the micro‐leak path . The micro‐leakage paths will be blocked by reducing the height of micro‐peaks and the depth of micro‐pits, or increasing the diameter of micro‐peaks, which can realize a reliable seal …”

Intelligent wells equipped with the interval control valve (ICV), which have the potential applications to significantly improve oil production or control the water production of wells and fields, are more and more widely utilized in the oilfields. The radial metal seal of an ICV is intended to isolate the flow of produced fluids between the casing annulus and the well tubing. The contact mechanical behaviors of the radial metal seal are essential to the structural design and reliability of ICVs in the intelligent well. In this paper, the two‐dimensional axisymmetric assembly of the radial metal seal and the closure member is abstracted as a combination of interference fit model and cantilever beam model. Based on that, the related theoretical model, between the radial metal seal's contact stress and its independent variables, has been derived. Next, numerically simulations of contact stress between the radial metal seal and the closure member for different independent variables are conducted by the finite element method (FEM) to validate the theoretical model. It is found that the mean absolute value of relative error between the numerical and theoretical results of the contact stress is approximately 10%. Additionally, the structural parameters of the radial metal seal are proposed with the absolute value of relative error <10%. Furthermore, the value of the contact stress based on the cantilever beam model can be used to calculate an approximation theoretical solution. In summary, the proposed theoretical model provides a foundation for the design, improvement, and selection of radial metal seal under the known oilfield conditions.

“…To verify the leakage rate experimentally British, ASME and API, standards can be used. Recent experimental work by Haruyama et al (2013) and Geoffroy and Prat (2004) have shown promising methods of detecting and quantifying leakage and its link to the transmissivity K and diffusivity D values. More specific research into PRV leakage which detracts from surface finish has been conducted by Ritchie (1989) which examines the effect of misalignment of the valve and its effect on pressure drop.…”

This chapter is part of a research program to investigate and model the leak tightness of a Pressure Relief Valve (PRV). Presented here is: a literature review; high temperature numerical study involving the deformation of contact faces for a metal-to-metal seal accounting for micro and macro effects; and also microscopic measurements of surface finishes and how they are modelled over a micro to nanometer scale. Currently, no review of literature exists which attempts to understand the leakage phenomenon of metal-to-metal seal contact PRV for static closed positions as they reach the set pressure point. This work attempts to do just that by drawing on inspiration from other research areas such as metal-to-metal contact and gasket seals. The key topics of interest surrounding the leakage of fluid through a gap are: fluid flow assumptions, surface characteristics and its deformation, and experimental techniques used to quantify leakage. For the numerical study, the valve geometry is simplified to an axisymmetric problem, which comprises a simple geometry consisting of only three components: a cylindrical nozzle, which is in contact with a disc (representing the valve seat on top), which is preloaded by a compressed linear spring. The nozzle-disk pair is made of the austenitic stainless steel AISI type 316N(L) steel. In a previous study, the macro-micro interaction of Fluid Pressure Penetration (FPP) was carried out in an iterative manual procedure at a temperature of 20 • C. This procedure is now automated and implemented through an APDL script, which adjusts the spring force at a macro-scale to maintain a consistent seal at elevated temperatures. Finally, using the Alicona Infinite Focus the surface form and waviness is measured, presented and modelled as 1/4 symmetric over a macro to nanometer scale. It is clear the surface form also needs to be accounted for, something which the literature does not focus on.
