Very helpful, Lee… I’ve been using this method of locating tank nozzles for years, but I never knew that it was called “strapping”….

hey found one… thanks anyway….

well the rain machine is a little out of my realm, but have a safe trip… and thanks for your help with the NH3 line…

Anton,

I found a mechanical joint-type flange from Clow Canada that is a series 40, but it’s probably not the same as a flange connected to a compressor….. doesn’t James know what these are? Go to http://www.clowcanada.com/english/flange_series40.html for a peek at what I’m referring to…..

Regards,
Bob

Jop,
I generally like to include large process ducting as if it was a piece of equipment to contend with.

Hello Jop,
Shouldn’t the Squad Check set be checked by the originating discipline (or squad) PRIOR to perfoming the actual Squad Check that includes the other disciplines (or squads)?

I had never thought of flexibility in those terms, Shrivallabha… thank you.

Hey Anton,
No… I guess that it really doesn’t make a difference in terms of actual piping… it’s more of a “tomato” vs. “tuhmahto” thing… but I’d really like to find out what other piping designers’ conceptions are.

When there is an actual lateral branch from a header (and the original header continues down the pipe rack, for example) the line number changes, as you say, and is this branch still considered a “header” or is it now a sub-header”?

I know that it may not matter… which is probably why I’m so OBSESSED with it (smiling)…

First of all… thank you to everyone who replied to my seemingly simple post. I, too, have done a little more research including writing to the Assistant VP of Product Engineering at Bonney Forge (weird huh 11echo?… smiling). These mythical 9000# S.W.unions actually appear in a published job piping spec by a fairly large engineering firm, but my feeling is that they were painstakingly fabricated from scratch to suit a corrosion allowance (3/16″ C.A.) instead of having to adhere to a prescribed pressure-temperature curve.

The Bonney Forge VP basically told me the same thing, 11echo. They are not governed by MSS SP-83 criteria so who knows what the dimensions are… thanks again for all of the positive response!

A fellow senescent piper,
Bob

p.s.
hey Jop… thanks for the new word, but I’m so senescent that I’ll probably forget it tomorrow (smiling)…

It’s Process steam, James… DP=290psig, DT=550°F, OP=225psig, OT=500°F in between a 1st stage flash drum and eventually to an atmospheric flash drum. It travels between the two drums through a flow control set about 12 meters from the atm. drum.

Then another steam stream travels from the top of the initial flash drum, through a pressure control set resulting in 40# steam to users.

Thanks,
Bob
