Abstract
The invention provides an assembly for hydrostatic testing of welds between components, such as but not limited to welds which connect components such as nozzles (2) or patches (40) to a pressure vessel (1). A sealing body (8) is secured against one of the components to define a sealed space (25) adjacent to the weld (5) to be tested. The body is secured by at least one tie rod (9), positioned to pull the body against the component by tightening of a nut (12). Pressure testing can then be carried out by introducing pressurized fluid into the sealed space and applying appropriate monitoring techniques to check for leakage.
Claims6
A weld testing assembly for hydrostatic pressure testing of welds between a patch connecting two components, said weld testing assembly comprising:
- a body securable against at least one surface of at least one of said components so as to define a sealed space adjacent to the weld to be tested;
- and
- at least one port for receiving a pressurized test fluid into said sealed space;
- said body being provided with one or more threaded tie rods and one or more nuts adapted to be threaded on said tie rods;
- said at least one tie rod is secured to said patch and tightening of said nut forces said body towards said patch, said body extending beyond said patch such that said sealed space includes said weld.
A method for testing a weld between a first component and a patch on the first component, comprising the steps of:
- providing a sealing assembly comprising a body adapted to be forced into engagement with at least one surface of said first component, said body extending beyond said patch;
- providing at least one threaded tie rod secured to said patch;
- securing said sealing assembly against said at least one surface so as to define a sealed space adjacent to, and including, the weld to be tested, said sealing assembly being secured against said at least on surface by tightening a nut on each of said at least one threaded tie rod such that tightening of said nut pulls said body towards said patch;
- injecting a pressurized test fluid into said sealed space;
- and
- monitoring said sealed space for indicia of a leak of said test fluid from said sealed space.
A weld testing assembly for hydrostatic pressure testing of welds between two components, said weld testing assembly comprising:
- a body securable against at least one surface of at least one of said components so as to define a sealed space adjacent to the weld to be tested;
- and
- at least one port for receiving a pressurized test fluid into said sealed space;
- said body being provided with one or more threaded tie rods and one or more nuts adapted to be threaded on said tie rods;
- wherein said body is comprised of two or more sections, each of said sections including a means for joining said sections together to form said body.
