Fig 754 Riser Clamp
APPLICATION: Fig. 754 Extension Pipe or Riser Pipe Clamps are recommended for the support and/or restraint of vertical steel pipes. A Fig. 754 Extension Pipe or Riser Pipe Clamp is designed to attach to the pipe and to rest on a structural member or floor; it is not designed to have hanger rods attached to it to support the pipe. Note that the maximum recommended service temperature for this pipe clamp is 650 °F. The clamp should be bolted to the pipe just below support lugs or other attachment that can carry a shear load. Placing the clamp just below adequate support lugs will prevent movement of the clamp along the pipe should the frictional resistance between the clamp and the pipe not be sufficient to support the pipe. See the table of torque values that are provided as a guide for tightening the bolts on the clamp.
CONSTRUCTION: Fig. 754 Extension Pipe or Riser Pipe Clamps consists of two carbon steel flat bars bent to shape and held together by two carbon steel bolts.
FINISHES AVAILABLE: Black, Hot Dip Galvanized, Electro-Plated or Painted.
ORDERING: Specify figure number, nominal pipe diameter, name and finish, if other than black.
EXAMPLE: Fig. 754, 8”, Extension Pipe or Riser Pipe Clamp, HDG.
