Abstract

The invention relates to a compression joint (3) for reinforcement of a tubular component (1), for example a reactor vessel (1). According to the invention, the compression joint (3) comprises a first sleeve (4) divided into a plurality of parts (5) along axial sections. The sleeve (4) is fixed around the component (1) by means of at least one winding (9) of strip or wire of memory metal. Also a second sleeve (10), in the same way divided into a plurality of parts (11), is fixed, at some distance from the first sleeve (4), around the component (1) by means of at least one winding (13) of strip or wire of memory metal. Before being wound around the respective sleeves (4, 10) at a temperature below the transition temperature of the memory metal, these strips or wires have been stretched into a suitable length to achieve the desired compressive stress in the joint after the winding on and a subsequent increase of the temperature of the winding above the transition temperature. The sleeves (4, 10) are provided around their periphery with a number of fixing devices (7) for a number of axially arranged tension elements (8) stretched from fixing devices (7) on the first sleeve (4) to fixing devices (7) on the second sleeve (10).
