Good morning everyone,
I would like to make an inquiry, I am repairing a oil pipeline built with X-52 material, I am offered to repair it with Type B sleeve with an ASTM A572 Gr 50

Although the A572 Gr 50 is a high strength steel, the mechanical properties are less than X52, I consider that I am demerging the pipeline, is there a standard that I can check?

Thanks in advance
 
Type B sleeve?

What design code are you using?

If you're repairing anything you're likely de-rating something.

Demerging??

Also: If you get a response it's polite to respond to it.
 
Derive the thickness of the sleeve plate using the applicable pressure design equations to achieve the necessary pressure rating.

The usual standard is API RP 2200/ASME PCC-2.
