FIG 255 PIPE ALIGNMENT GUIDE
|The Figure 255 Pipe Alignment Guide is designed to maintain alignment of piping through its axial expansion and contraction cycles.Specify size number, pipe size, insulation thickness, figure number, name and finish when ordering.|
|1″ through 24″ pipe and insulation thickness of 1″ through 4″|
|Carbon Steel, Plain or Galvanized|
|The primary function of the Figure 255 is to maintain axial alignment of a system. Other components should be incorporated into the system to carry the primary loading of the system. Guides are designed such that minor loading amounts may be transferred to the guide in any given direction, up to 20% of dead weight load for typical maximum spans of a given pipe diameter.|
Normally, two or more pipe alignment guides are used on a single piping run to avoid a pivoting effect within the piping system. It is recommended that the first guide be located a maximum of four pipe diameters from an expansion joint. The second guide should placed a maximum of 18 pipe diameters from an expansion joint. Additional guides should be employed in accordance with the guide spacing data contained in the table below. Supports are usually required between the intermittent guides to comply with standard support practice.
- Attach outer housing to structure by bolting or welding.
- Remove upper section of housing to open position.
- Attach spider clamp to pipe and completely insulate.
- Set pipe and spider clamp into outer housing.
- Replace upper section of housing to closed position and secure.
Note: Spider attachments to pipe must be properly located to insure that a minimum of 1/2 the spider width remains within the length of the outer housing for all conditions of operation. See table above for maximum recommended travel. If larger travel values are required, special guides can be furnished to special order.
