Abstract
The purpose of the end fitting seal system is to ensure leak proof
termination of flexible pipes. The seal system of an NKT end
fitting normally consists of a number of ring joint gaskets
mounted in a steel sleeve on the outside of the polymeric inner
liner of the pipe. The seal system is activated by compression of
the gaskets, thus using the geometry to establish a seal towards
the inner liner of the pipe and the steel sleeve of the end
fitting. This paper describes how the seal system of an end
fitting can be tested using an autoclave. By regulating
temperature and pressure, the seal system can be tested up to
130oC and 51.7 MPa. Pressure, temperature and the mechanical
behaviours of the pipe are measured for use in further research.
The set-up is used to test the efficiency of the seal system as
function of parameters such as cross sectional shapes of the
gaskets, tolerances between gaskets and inner liner, number of
gaskets, surface roughness and gasket material.
