On-site pressing of field poles for a hydroelectric generator is provided. A field pole may be placed on a press cart and press bars may be placed on top of the field pole. The press cart is moved along a track to transport the field pole to a pressing unit. Hydraulic cylinders in the pressing unit press the field pole and the press bars between the cart and a top plate of the pressing unit to straighten the field pole.

Metallic tubular products having improved collapse resistance are disclosed. The metallic tubular products are produced by compressive forming processes. The method comprises identifying the types of stress that can be applied in order to change the residual stress profile of metallic tubular products, such as those that have completed a straightening process, and results in a residual stress profile that improves collapse resistance. The metallic tubular products are subjected to radial compression processing to control the residual stress profile and to enhance collapse resistance. The radial compression process may be used after the tubular product has been subjected to a straightening process.

A method to improve the collapse resistance of metallic tubular products is disclosed. Stress is applied to the metallic tubular products in order to change the residual stress profile of the metallic tubular products, such as those that have completed a straightening process, resulting in a residual stress profile that improves collapse resistance. The metallic tubular product is subjected to radial compression processing to control the residual stress profile and to enhance collapse resistance. The radial compression process may be applied after the tubular product has been subjected to a straightening process.
