It depends on the geometry, boundary conditions and material properties. If it's a simple cylinder where at a given axial location the displacements are axysymmetric, then you can just get the displacement normal to an edge, which will be equal to your change in radius and multiply it by 2 to obtain the change in diameter. Image 1.
A more general approach will be to create a parametric 3D curve snaped to the boundary of your interest (Image 2) and then get a line average of the radial displacement (image 3). If the center of this pipe moves due to external loads or uneven pressure distribution, then first you would need to calculate the average center of the parametric curve, and then calculate the average radius by subtracting those coordinates from sqrt((x-x0)^2+(y-y0)^2).

Thanks Luis for your response. This will help me.
