An elbow and reducer was thinning, causing the plant to fear that it may one day leak sour product. A 2-box connecting design with 7 bores was designed to enclose the entire elbow and reducer. The challenge with this one was ensuring the enclosure could be installed with many obstructions close by, ensuring it would be stable on the line, and making sure there were no leak paths. With the help of accurate scan data and virtual installation tests, this enclosure will work just fine.
