Re: Confusion regarding BW , BE and PE.

BE might be needed for different process fluids, ask the requestors if they really NEED it or if they think it just looks cooler. Look for BE small piping on specialty service. You might need it for cryogenics (smaller mass for quicker component cooldown) or clean service (less crevices for foreign matter to collect).

BE and BW are mutually exclusive, you either do one or the other. You may need a BE swage to make the transition from large-bore to small bore piping, though.

Look up the welding page <a href="http://www.pipingdesign.com/welding.html">http://www.pipingdesign.com/welding.html</a> for more information about pipe welding.
