Thanks Borzki, the plant has only been operating for three years. I believe the main issue is that the line is overstressed at leak locations "shoe support and tee" so we will propose changing pipe material from A105 Gr B to A691 9CR since this is the material of the main 36" header. Also the additional loop is relaxing the line a lot since the relative movement between both headers is quite high. A good idea is the clamped shoe support but the pipe support standard does not have this at this temperature.
