I am looking people (someone, anyone) who have experience with high temperature pipe-in-a-pipe systems. I was told of a facility that uses a such a system for hot air at 1350+ F and 650 psig. The inside pipe (12") is vented to the outside pipe (~20") such that it is not pressure retaining; it...
I have been looking at a PDP (Parallel Disc Press) butterfly that is being offered in the USA by a company called "Critical & Severe Service Products, LLC (www.critical-severe.com). I believe they are actually manufactured in Korea and distributed by Critical & Severe Service Products in the...
Has anyone tried A+ flowtek's balanced flow meters (http://www.aplusflowtek.com)? I am trying to find people with first hand operational experience to support or dispute their claims of flow metering accuracy to +/- 0.5%. They are a NASA spin-off company. I also know that Texas A&M did some...

We are currently investigating the installing a 16" nps 0.500" wall pipe to carry 1200F air at 450 psig. Due to the manufacturing dimensional tolerances of SA312 Type 316, the maximum allowable working pressure calculated per B31.1 is below the design pressure of 450 psig. Instead we have...
I would appreciate any help you guys can give me on this issue.

I am currently reviewing a Section VIII pressure vessel design and am stumped as how to verifiy the possible need for reinforcement in a 6" 300# blind flange that is drilled through the center with multiple penetrations. The blind flange has twenty 7/16" diameter penetrations that are spaced...
We are considering using a steam trap that utilizes an ISO standard venturi nozzle to remove the condensate from the steam system. It has no moving parts and appears to be very energy efficient. Our testing shows that it works well under varying loads (above 15% of rated max load). The venturi...
I am looking for a high flash point hydrualic fluid that is "user friendly" (ie, easily handled and noncorrosive). The fluid is used to actuate the hydraulic actuator on a valve in a piping system. The system piping is 900F and the fear is that if the oil contacts the hot surface or creates a...
