This matrix is offered as a basic point of reference for dimensional accuracies off the flowforming equipment. The specified minimum and maximum wall thicknesses for a given diameter range, as well as other shown limits, are not fixed and can be varied to meet your requirements. It should be noted, however, that the degree of dimensional accuracy is highly dependent on the material of the component, its size and thickness, as well as possible distortion caused by the requirement for any post-forming heat treatment. As such, applicability of dimensional tolerances is on a case by case basis.

CAPABILITIES: Our flowforming capabilities range from diameters of .866” to 25.600” (22-650mm), wall thicknesses from .006” to .600” (0.15-15mm) with lengths up to 26.5ft (8 meters). Since flowforming poses no limitations on the relationship between component diameter and wall thickness, quite often we produce large diameters with precise, thin walls.
