I am in Alberta Canada. We have come across a situation that we have identified a pipeline that was installed back in the 90's had an install temperature of 10C, which puts us at a max operating temperature of 75C, however our max operating temperature of the pipeline is 85C based on the external coating. We wish to increase the operating temperature up to 85C but still keep the MOP of the pipeline at 9930kPa. Does anyone have any experience with this and provide any help on what we can do?
My only thought is that we would have to remove the anchor blocks on the pipeline and heat the pipeline (from what I understand there is a service that provides air heaters to increase the install temp of pipelines) to an acceptable temperature, and then re-install the anchor blocks. Thus giving us a new install temperature at time of restraint.
