Does anyone have the UT shearwave formula for calculating the sound path and surface distance for a tubular, following the curvature of the tube, for a given angle, O.D., and thickness? Thanks.

Re: Shear wave formula You can use the Thickness-OD ratio charts for calculating beam path and surface distance for tubular products. This is useful only for the direction perpendicular to the pipe axis. Replicating the surface curvature using profile gauge or lead wire and plotting it on a paper is very useful for curvature correction at any angle. This is mostly useful in testing of TKY connections.

Re: Shear wave formula Sorry I am a bit late getting in on this thread. SOme years ago I made the NDT ProblemSolver Software available on NDT.net. you can download it from http://www.ndt.net/publicat/bibliog/pss.htm

It is based on old DOS so a bit less splashy than today's materials but there is a section in the UT version that does geometry calculations. You enter diameter wall thickness and refracted angle from either the ID or OD and the distances are calculated. Hope it is useful.
