S-730-C — Chair and Roll
Designed for longitudinal movement of pipe where vertical adjustment is not required.
Because the chair is made of steel, it can be either welded or bolted in position.
Material: Carbon Steel Chair and Axle with Cast Iron Pipe Roll.
Use a Figure 17 when a Cast Iron Chair is required. Do
not exceed 450°F / 232°C at the contact point to the roll.
Compliance: Federal Specification A-A-1192A Type 44, MSS-SP-69 Type 44.
Finish: Black (add suffix “-B”).
Electro-Galvanized (add suffix “-HDG”).
For pipe with insulation and a pipe covering protection saddle,
the S-730-C will have to be oversized to suit. Please see the
Table below showing the correct sizing for insulated pipe.
Ordering: Specify chair number, catalog number and finish.
