Thanks for the input, it is very much appreciated. I wondered if I was trying to apply something that wasn't meant for the case.

Hi BigInch, We are still not entirely on the same page. I am using a tee, not a branch connection. The tee is a B16.9 XS welding fitting. The requirement for reinforcement is not based on any pressure or material replacement requirement, but purely on the code requirement I quoted, which...

Ah, you meant a full encirclement support on each side of the tee. Sorry, a bit slow... If I do that the stresses in the tee are too high.

Thanks for the reply This is for attachments welded to the pipe, there is no wear aspect to this requirement. The full encirclement is required so that welded attachments "will not cause ... excessive localized bending stresses, or harmful thermal gradients" in the pipe; from section 404.3.4...

Hi All, I am designing some piping according to B31.4 and this includes a number of places where supports are welded onto the pipe. I am using full encirclement as per the code at these locations, as the stress is > 20%. However, I am not quite sure what to do at a location where I need to...

Thanks to all for the input.

Hi, I have a VFD controlled 55 kW motor running a centrifugal pump through a gearbox. The motor runs at 50Hz with the current setup. Not a vary variable duty, almost fixed speed with occasional slight variation (about 5Hz). Someone has suggested removing the gearbox (for a new stream, same...
