PT&P designed and manufactured two hundred and thirty HD-2 hold down clamps to fit 6” to 8” pipes at a chemical refinery. These hold down clamps are used on pipe lines where there is a high temperature and great thermal movement requirements, they allow axial movement and restrain lateral movement at the same time. The clamps are fabricated from carbon steel with 3/32” PTFE, 25% glass filled, bonded to the radius. The plates are manufactured from three layers of materials; 3/32” PTFE, 25% glass filled, 1/2” thick fabric belting material and carbon steel.
