After joining 2-3 pipes with butt joint, straighness of the centre line is deviated due to the thermal stresses and fitup face out.
To bring back the component to a straight pipe, mechanical pressing is done using hydralic press, supporting the component as a simply supported beam and the load from centre. Plastic deformation is obtained with max deforming force of 500 tons. Is the same process acceptable to creep strength materials like Grade 91/92 ? What is the max thickness of the pipe that can be straightess corrected with this available pressing force
