    Right click, pick options, click on the display tab (upper left) click on the Colors button. Under content pick 2d model space or Sheet/Layout depending on what you’re working in. Under Interface element pick Uniform background and finally under color change to black.

    Welding of slip-on flanges

    @ ansh93; First welcome to Eng-tips forums, it’s a great place to get information and learn. My advice when asking a question is to added as much detail as possible. To use your original question for example, if you have a specific situation that you need to install a slip-on flange include as...

    Welding of slip-on flanges

    To expand on my yes answer from earlier. Our inspection procedures call for a dye check on the root & final pass of both of the weld locations. On top of this a 1/8 inch hole is drilled and tapped into what will be the space between welds, prior to installation, so that when all welding is...

    Closed Cooling Tower System

    The “cooling tower” in your thread title got me thinking, like the previous responders, of a different type of closed loop cooling system that uses an unpressurized gravity cooling tower. In theory it should not matter where you put the pump in your pressurized closed loop system. When it...

    Your opinion about this pipe support

    My thoughts: 1. Pipe shoe for 600 deg. line along with a good pipe stress engineer to determine the need for guides and anchors. 2. The specs I work with actually require ½” dia. smooth bar stock as the contact point on all supports. 3. The same specs do not allow pipe supports to be fabricated...

    4" low psi air piping requirements

    "...Consider that, if the piping system fails and someone gets badly hurt, a snarling, blood-sucking attorney may make some real money." And in this case, rightly so.

    4" low psi air piping requirements

    One of my questions would be. Is this truly a 60 psig system? If they are this careless with the construction, how much thought put into the process design? Is the system properly protected from over pressure? What is the compressor’s maximum psig output and what happens when this poorly...

    Rolling offset

    I use “The pipe fitter’s and pipe welder’s handbook” by Thomas W. Frankland as a reference and also found the following at Google books. http://books.google.com/books?id=c4QOZm9El4IC&pg=RA1-PA397&dq=45+degree+rolling+offset

    Drilling & tapping an elbow for relief valve

    I’m sorry that I can't help you when it comes to the code issue. That's the first time I've seen that configuration and I know it would not be allowed in the refinery I work at. It even gave my boss with 30 plus years of piping experience a chuckle.

    Method to design a big concentric reducer

    Search on the web for “The pipe fitter’s and pipe welder’s handbook” by Thomas W. Frankland. It describes what you are looking for. Now if it meets current codes? I can’t help you with that.
