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.
PT&P designed and manufactured forty PTP 200- type “E” constant hanger assemblies with pipe sizes ranging from 36” to 62” for an oil refinery in Canada. These constant hanger assemblies are designed to support and allow vertical movement of the field pipe during thermal expansion. The constants have a load capacity of 2800 lbs. to 9200 lbs. and a 3”-7” travel range. To assure quality, standard load testing was performed on the constants prior to shipping. The assemblies’ components consist of a constant load hanger, a rod and a clamp. The constants are fabricated from ASTM A36 carbon steel and the rod and clamp were manufactured from ASTM A240, Gr. 304 stainless steel.
PT&P designed and manufactured two 240″ x 12″ x 1/2″ Embed Plates with 3/4″ diameter weld-stud projections to be used in a concrete reinforcement application. All components are fabricated out of carbon steel with a hot-dipped galvanized finish. The plates were shaped to form a 45″ x 90″ frame prior to shipment. The frames were braced with 2″ x 2″ x 1/4″ angles to ensure the frame maintained its structural shape prior to installation.
PT&P fabricated heavy-duty roller stands, 60” and 72” in diameter, to support large pipes in a cooling tower. The roller stands support loads up to 60,000 lbs. while allowing the pipe axial movement during temperature fluctuation. To reduce friction the rollers are fabricated out of machined carbon steel. The round bar and the stands are fabricated from A-36 carbon steel plate.
