Two Hundred HD-2 Hold Down Clamps

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.

27' x 16' x 21' Structural Frame for an Offshore Site

PT&P custom designed and fabricated a 27′ x 16′ x 21′ structural frame to be placed on the sea-bed for an offshore rig. This assembly will be used as an undersea cable support frame, capable of withstanding a load of 600 Kilonewtons (68,000 lbs for each pad). It is constructed of 8 tube-steel, a 10 channel, and a steel plate. The frame will remain stationary on the sea-bed and is designed to endure heavy wave action when lowered to or raised from the sea-bed.

Finite element analysis of the lifting lug on the structure was performed to verify load conditions. A trial fit-up of bolted sections was also conducted to ensure the structural frame will assemble easily before being placed in position.
