A method for mutually positioning tubes. End faces, which includes a generally annular and generally circular end surface near an inner surface of the tube and a beveled edge surface connecting the end surface to an outer surface of the tube, are provided on first and second tubes, respectively. Plural clamping cylinders are engaged with the first and second tubes, respectively. Each cylinder is radially arranged onto and evenly distributed around respective tubes. The first and second tubes are pre-positioned relative to each other such that their respective end faces are opposite each other. At least one radial offset is assessed between the respective end surfaces of the first and second tubes. The clamping cylinders of the first and/or second tube are moved relative to each other in accordance with the assessed radial offset based on an optimization of areas in which their respective end surfaces coincide. |
