PT&P has extensive experience involving the custom design and fabrication of hold-down pipe clamps for piping systems and skid mounted units for the power, chemical, and refineries industries throughout the world. These hold-downs are custom designed to limit vibration caused by rotating equipment and avoid damage to the surrounding piping system. They are fabricated from carbon steel with a hot-dipped galvanized coating and include PTFE slide plates to reduce the friction between the pipe and clamp, combined with fabric pads to reduce vibration dampening. The hold-downs are designed for pipelines ranging in 2” to 16” diameter. They range from 3″ wide x 9-1/8″ long to 8″ wide x 25-3/4″ long, and designed for an operating temperature of 200°F. We performed a Q.C. visual inspection prior to shipment. PT&P can custom design and fabricate hold-downs for any pipe size application. In addition to hold-downs, PT&P also offers other types of vibration control devices to accommodate different pipe orientations and locations.

PT&P Designed and Fabricated Variable Springs for a Refinery in Texas City
Type: | G-Type Variable Spring Support Assemblies |
Design: | Operating Loads from 3000 lb. to 4000 lb. Movement of 1” |
Material: | Carbon Steel |
Testing: | Load & Travel Test | Q.C. Inspection |
Pictured here is a Type G variable spring hanger assembly designed for an operating load up to 4000 lb. and 1” movement. This type of support assembly is formed by welding two standard spring assemblies to the ends of a pair of channels. The Type G assembly is especially adaptable for avoiding interference in spaces where the headroom is limited. The assemblies are fabricated from carbon steel and underwent spring load tests before shipment.

Material: | A36 Carbon Steel | Hot-dipped Galvanized |
Design: | Operating Load Range: 3,170 lb. to 48,400 lb. Movement of 3” to 8” |
Testing: | Q.C. Inspection | Load and Travel Tests |
PT&P manufactured B-type constant spring supports for LNG service in Louisiana. These constants are fabricated from A36 carbon steel with alloy steel 5160 spring coils. The constants are designed for an operating load range of 3,170 lb. to 48,400 lb., and movements from 3” to 8”. They range in size from 11-5/8 W x 41” L x 19” H to 21” W x 88” L x 38” H. To avoid delivery delay, a standard frame was paired with an oversized coil and coil housing. The lugs were rotated 90 degrees from the standard to allow the hanger to swing beyond +/- 4” of side-to-side swing. Standard load and travel tests were performed prior to shipment.
