Piping Technology and Products, Inc. recently designed and manufactured two HD-2 hold down clamps to fit a 16” pipe at an oil refinery in Michigan.  These hold down clamps are designed to be used on pipe lines where there is a high temperature and great thermal movement requirements. They allow axial movement while restraining lateral movement. The clamp and base plate are fabricated from carbon steel with PTFE, 25% glass filled, bonded to the radius and plate.
