ATS Model “GA” Radial Pipe

Alignment Guides
• ATS Model “GA” Radial Pipe Alignment Guides ensure positive pipe
alignment by restricting pipe movement in all directions except
along the axis of the pipe.
• Recommended choice as the “Primary” guide in piping systems
which utilize the ATS Thermal Pak “TP2” Expansion Joint. See
Page 2 “General Guidelines for Guiding and Supporting Pipe” for
recommended spacing and locations of pipe guides and supports.
• The “GA” Guide Assembly consists of a body cylinder which can
be either bolted or welded to the support structure and a sliding
spider that is attached to the pipe. The spider moves through the
housing as the pipe expands and contracts.
