I'm looking for some information about using air movers (air handlers) to evacuate natural gas from a pipeline. So far I've been able to come up with the AGA purging manual, and parts 1 and 2 of an article titled "Performance of expellers in evacuating gas pipelines". The article and the AGA...

Hello, My brother recently graduated with a computer engineering degree. He is thinking that there is little to no value in getting a PE for computer engineers. What do you guys think? Thanks.

I know that the experience requirements vary by state, but could you guys give me your opinion based on what your experience has been? I'm looking at a job that is labeled as "construction supervisor" at the company I currently work for. It would require some field adjustments of office...

Anybody know which standard Grade B 3-R elbows are manufactured to? I would think it should be ASME B16.9, but I can't find a reference to them anywhere in that code. Thanks, Pat

Is there an acurate way to predict the amount of flow through a partially opened valve? Particularly a plug valve flowing natural gas.

Does anyone here have the Anvil (Grinnell) Piping design and engineering manual? I'm just wondering what kind of information it has in it. Thanks

We've been having some discussions about welding materials of different thicknesses and can't come to a conclusion, so maybe someone here can help. The instance we've been talking about is welding a sleeve onto a carrier pipe. The carrier pipe is .250" X-70. The Sleeve is .750 X-52. The...

Hello, I've been asked to research monolithic insulators for use on natural gas pipelines ranging from 3" to 16" and just wondering if any one out there has had any experience (good or bad) with them. We'll be using them to seperate line sections so we can conduct studies on the...

Hello, I'm looking at getting a book to help with estimating time for ditching, welding, etc. involved with natural gas pipeline work. Do you guys have any favorite books? I was looking at a book by John S. Page called "Estimator's Piping Man-Hour Manual" Any experience with this...

Does a forged steel flange have a derating factor associated with it for construction type? Example: In a pipeline used for natural gas transmission service there is a derating factor for piping used in areas with higher populations of people .6 for areas that are remote and .5 for areas like a...
