    Welding an olet on a welded cap

    Hello everyone, Just a quick question....is there any standard that prevents me from welding a threadolet/flexolet on the end of a welded cap or even limits the size of the tap as well? I've looked through some applicable standards but can't seem to find anything. Thank you!

    Distance between compressor building

    Is there a guideline (maybe from AGA) that provides requirements for the minimum distance between two compressor buildings so that they can still utilize the same ESD system? For example if there are 3 compressor buildings in the same facility, what is the minimum distance they can be from each...

    Pipeline Class Locations

    This is just a general question but where do the requirements for the class location originate from? So for example, a class 1 is intended for 10 or fewer buildings or dwellings. My question is why is it 10 and not 11 or no? Who made the decision that it was 10 for class 1 and 46 for class 2, etc?

    Liquid Hydrocarbon Permeation and HDPE Pipe

    Hi guys We're having some issues with the inability to fuse HDPE pipe which has been attributed to the natural gas quality, specifically hydrocarbon liquids. These is indication of bubbling of the plastic after preheat making it difficult to get a high quality fusion. I've done some research...

    Filter Separator Flash Fire

    Last night we had a small incident at one of our station and I was looking to see if anyone else has seen this before. A filter separator was left over night to air out before the filters were changed. When operations got on site they saw a fire around the door of the vessel and had to put it...

    EG/TEG Solubility with NaCl/CaCl2

    Has anyone ran into any charts that show this? I've just seen EG/TEG/NaCl/NaCl2 with water. Any help would be appreciated. I'd like to see something showing how temperature affects this. Thanks guys!

    Zebra Mussel Control

    We have a cooling water system at one of our compressor stations that use cooling water from a local pond (that contains zebra mussels) to cool down natural gas discharge from compressors through heat exchangers. We are having issues with the mussels plugging off the exchangers and having to...

    mcketta wehe chart

    This may be a stupid questions but the temperature on this chart is the dew point temperature correct and not the temperature of the actual gas? Thanks!

    Heat Exchanger Vendors

    This is just an opinion question but have you guys had previous dealings with either cust-o-fab, perry products or southern heat exchanger? How would you rate them? I'm looking to purchase some heat exchangers from one of them and have never done business with either of them. Thanks a lot

    Body Bleed Valve

    I was wondering what kind of valve would you guys recommend for body bleeds on large valves (ANSI 600 and 900). Currently we have been using WKM's and Balon but they seem to leak over time, which makes it dangerous for operations to remove bull plugs on the end of these valves. Any valves that...

    Throttling Valve

    What is a better valve for throttling natural gas with a high differential around the valve? Ball, plug or globe? To me, I thing a globe would be the best option but I know a lot of people choose the plug instead. Could someone please clarify for me. Thanks!
