Tube Expanding

Expanding is a method used to increase the diameter of a tube. In general, a stainless steel tube can be expanded up to 40%, but in some cases, certain materials can be worked farther. The amount of expansion is related to the thickness of the tube wall and the diameter. Some thinning of the wall should be expected after the expansion process. The inner diameter of the expanded tube can be held to +/- .002". Special requests for OD or ID tolerances can be considered also.
