Howdy all,
I'm trying to track down information on a piping code, CODETI, which I believe is a French Industrial Piping Code. Any ideas where I can buy the most recent (English) version, or has it been superseded by EN 13480 (or some other European standard)? Who is the body that publishes...
Hi folks.
I'm doing some design work for piping in Toledo, Ohio, and I would like to know what regulatory body, or legislation, governs the design of piping in this area. Piping is mostly B31.3, all of it is in a refining facility.
Any links, or references, would be greatly appreciated.
Alright...this is probably not the best place to post this, but I'm lost.
I have a drawing in Intergraph's Smartsketch that I want to get into a Microsoft Word document. I've tried saving the image in a .tif format, but the printout from word looks like it was run through a fax machine. I...
Alright, somebody please correct me if I am wrong here.
ASME B31.3 302.3.1 states "The allowable stresses defined...shall be used in design calculations unless modified by other provisions of this code." It then goes on to state that the design stresses for bolting materials are as per Table...
I'm trying to find out what the 1997 version of ASTM A350 says regarding the LF2 material. 1996 does not specify different classes, the 1999 version specifies Class 1 and Class 2. Does 1997 specify different classes?

Alright. I have a list of pipe sizes, formatted as text. For example,
3"
6"
1-1/2"
1/2"
26"
I want to convert these to numbers. What I have done is:
1) Determine length of text string =LEN(...)
2) Strip off inch symbol =LEFT(...,LEN-1)
3) Convert to number =VALUE(...)
This is a little bit...
I have come across a reference to a formula that I can't track down. Specifically Roark's Formula's for Stress and Strain, 4th Edition, Page 354, Item s(34).
I have access to a 5th edition and a 6th edition. Anyone able to tell me the equivalent in one of these editions?
Thanks in advance...
Anyone know if there is a backwater (check) valve that can be installed directly on the drain of a sink? I did a very quick search on the internet, and looks like most of the valves are designed for the main sewage line heading out of the building. I have a particular application where I only...

Hi folks,
I am trying to figure out how to determine the fire endurance rating of an insulated pipe. Anybody have any advice on how to go about doing this? A quick methodology, or a good reference to the topic would be appreciated.
Will this be specific to each insulation manufacturer, or...
Hey folks,
If there are any committee members out there, I'd like some insights into the workings of the B31.3 committee.
I sent an inquiry into the B31.3 committee in November of 2002. Actually, it was a request for either a code case (which I know is very rare) or a reconsideration of a...
Hi there. Just wondering if anyone is aware of a good software package that is suitable for designing and evaluating pipe tracing/insulation systems. I'm specifically looking for something that would be good for designing thermal oil tracing systems.
Any advice appreciated.
Hi folks,
Imagine that I have a 600# ASME B31.3 piping system with a minimum design temperature of -29°C. Now imagine that it is -35°C outside and the piping is also at that temp. If a person were to run low pressure steam through the pipe until the metal temperature reached -29°C, and then...
Hi folks.
Does anyone out there have any background on how the weld joint quality factors (Ej) in Table 302.3.4 of ASME B31.3 were derived?
I am trying to put together an argument that 100% radiography of welded pipe is not required because any flaws in the weld are more than compensated for...
Hey folks. I am looking for a good reference, handbook, or anything on the design of steam tracing/electrical tracing/hot oil tracing systems (and associated insulation)for piping. Our company has all kinds of charts saying "use two steam tracers and 2 inches of insulation", but they...
Hi folks. I was looking through the ASTM A53 specification and noticed that ERW piping can be supplied either nonexpanded or cold expanded, at the option of the manufacturer. What does this mean? I believe that it has something to do with getting the piping to the final tolerances, but am not...

OK. Here is the situation. I have a very complex Excel spreadsheet. I want to vary two of my inputs, and check what happens to a single output. I want to do this thousands of times so that I can analyze some trends.
I thought what I would do is create an Excel component within Mathcad...
