I am working on a design where we are routing compressed air in type k copper tubing and Liquid Petroleum gas in sch. 40 black steel. The pipe is located in an area of a building exposed to external blasts. I am looking for the maximum allowable stress that would be allowed for the above...

If I am in a 3-D seed. How do I rotate about the x-axis?

I am new to Microstation j716 and trying to develop piping isometrics. I am able to draw isometric lines easily per the Isometric settings on microstation. However, How do I insert valves in the proper orientation? If the x-axis runs horizontally on my screen, how do I rotate with respect...

It is my understanding that DI water at 18 megaohm is pure H2O. Can someone explain to me why when DI travels through cast iron pipe that it will cause the cast iron to leach into the fluid stream? Is the statement above even true? Is this statement true for all metal piping? ie., copper...

I want Autocad to calculate and label pipe sizes as I draw the piping system in plan view. Once the piping system is drawn in plan view, I want Autocad to convert it into an isometric. Where do I began? Can anyone suggest any good reference books I can start with? My background is...
