Hot Tap on Elbow

Hot Tap on Elbow

Hot Tap on Elbow

Have a scenario, where I had to weld a 2" piping connection (through HOT TAP) on to an 24" A234-W elbow, oriented in skewed direction, i.e., elbow rotated in 2 plane.
would like to explore the feasibility of executing hot tap of 2" connection anywhere in the surface of the elbow or is there a limitation on the location / orientation of the Hot tap on an A234 fitting.

RE: Hot Tap on Elbow

This isn't really a Safety relief valve question but should be in the pipelines and piping forum...

My issue / thought is more around the fitting you're welding on.

Most "elbowlets" are intended to be welded in line with the plane of the elbow and are contoured that way. So whilst you could rotate the location around the circumference at least a small amount, you can't "twist" the elbolet on its axis as the re-inforcement will be wrong.

I would suggest an FEA of this strange orientation as well.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Green light on lidar: Developing low cost systems for autonomous vehicles
Lidar has been around for quite some time, but to date, it’s been custom—and expensive. Right now, there isn’t a clear-cut solution that’s suitable for all applications, such as lidar in autonomous vehicles. As they explore options, optical and mechanical engineers are forced to make choices and tradeoffs during the design process. Download Now
