In my past experience, the line would have to be cut and pulled from the casing. The pipe would then have to be reinserted with new insulators(spacers)and then tied back in.

MikeHalloran: Thanks for the response. I have a client asking for "material for instrument tubing shall be stainless steel with a safety factor of 6:1". It didn't mean anything to me either.

How does a 6:1 safety factor relate to stainless steel tubing specfications?

Thanks again metengr. I can take it from here.

Thanks metengr for the response. I had found some internet information that indicated the general differences in allowable stress levels of the two grades of bolts. If I were to have two mated 300# flanges at 150 Degrees F, what impact would Grade B7M over B7 bolts have on the pressure rating of...

Is there any impact on the pressure rating of a flange with utilization of B7M bolts versus B7 bolts?
