Fozy,
We are quoting to make a saddle for a pipe to enable the a tee to be cut into it without cutting the pipe apart. I just need to source some 35mm thick LT60 (or equivalent, as this is a flange material spec). It isn't subject to particularly high pressures (only 190 bar max, but has to be tested to 285 bar), but due to it's application (oil & gas industry), it must be of this type material.
