PURPOSE:To provide a pipe supporting device for thermal-cutting which simply centers without generating the centering slip of pipe even if the diameter of the pipe to be machined changes, and which is made compact without enlarging the device itself even if the diameter of pipe enlarges. CONSTITUTION:Freely rotating left and right rotary shafts 37L, 37R are installed on a base plate 27, lower parts of arm members 57L, 57R which freely swing synchronously with this each rotary shaft 37L, 37R are supported, and together freely rotating work supporting members to support a pipe W to be machined on the upper part of each arm member 57L, 57R are installed. |
