Fig 736 Standard 3 Bolt Alloy Pipe Clamp
APPLICATION: Fig. 736 Standard 3 Bolt Alloy Pipe Clamps are recommended for the support of hot piping with insulation when the temperature exceeds 750 °F and is less than 1050 °F. Fig. 736 Standard 3 Bolt Alloy Pipe Clamps have been designed to carry loads that are not large in magnitude. The 3 bolt design enables the attachment to the pipe clamp outside of the insulation. For high temperature piping with thick insulation and a loading larger than this clamp will carry, a Fig. 739, 742 or 745 3 Bolt Alloy Pipe Clamp may be used. Or, if the temperature and loads dictate, Alloy Yoke Clamps, Fig. 748 or 751, may be used. The selection of the proper 3 Bolt Pipe Clamp depends upon the temperature of the piping system and load to be carried. The loads shown on the data chart are listed for 950 °F, 1000 °F and 1050 °F service.
CONSTRUCTION: Fig. 736 Standard 3 Bolt Alloy Pipe Clamps are made from ASTM A387-Gr. 22 steel plate or bar stock and are provided with three alloy bolts and nuts.
FINISHES AVAILABLE: Black.
ORDERING: Specify figure number, nominal pipe diameter, name.
EXAMPLE: Fig. 736, 8”, Standard 3 Bolt Alloy Pipe Clamp.
