Hold-Down Pipe Clamps

Hold-down pipe clamps are used in applications where you would like to either 1.) anchor the pipe in position or 2.) permit axial movement of the pipe. Slide plates, such as PTFE, 25% glass filled or graphite, can be incorporated into the design to reduce the friction between the pipe and clamp.

Fig. HD-3: Arrestor Type Hold-Down

MATERIAL: Carbon steel
FINISH: Galvanized
TEMP: 200°F
APPLICATIONS: Fig. PTP HD-3 is an arrestor type hold down. This hold down is actually a restraint that is used when there is very low thermal movement. Its radius is lined with a belting material that is well designed to absorb shock from vibration. This type is generally used on compressor lines or similar application.
ORDERING: Specify figure number, pipe size and description.
NOTE: Belting material remains impervious to heat up to 200°F.
