Hold-Down Pipe Clamps for a 20" Pipeline at a Waste Disposal Facility

These hold-down pipe clamp assemblies are specially fabricated and include wedges with 25% glass-filled PTFE to absorb vibration and also serve as a buffer between the steel pipe and pipe support. Vibration can occur in Power, Solar, Biofuels, and Chemical plants because of flow-induced and/or acoustic-induced vibration due to the flow of fluids or gas/steam through the piping system. Similarly, vibration can occur in pipelines near rotating equipment such as reciprocating pumps and compressors resulting in pulsations or mechanical forces that can occur in both onshore or offshore production facilities. Vibration can be strong enough to cause premature failure or cracks resulting in unplanned shutdowns. These units shown in the photograph are custom-designed for pipe sizes up to 20″ in diameter and temperatures up to 200°F and can be adjusted to accommodate a range of heights for the T.O.S to the B.O.P. They are 21″ wide x 26″ long x 23″ high and are proven to greatly reduce vibration to acceptable levels. These hold-down pipe clamps are fabricated utilizing A 36 carbon steel plate and A 307 Gr. All-threaded rods. All components were hot-dipped galvanized and a quality control inspection was performed before shipment.

Variable Spring Supports Designed for a Highly Corrosive Environment in Peru

Type: Variable Spring Supports w/ PTFE Slide Plates
Size: PTP-4 | 9.5″ – 11.5″ Height
Design: 1/8″ Upward & 3/16″ Downward Travel
Material: HDG Carbon Steel | Gloss Aliphatic Polyurethane Topcoat | PTFE, 25% Glass Filled Slide Plates
Testing: Standard Load Testing & Q.C. Inspection

Piping Technology & Products, Inc. recently designed and fabricated F-type variable spring supports for a plant in Peru. The variables are fabricated from carbon steel, hot-dipped galvanized and a gloss aliphatic polyurethane topcoat was applied for corrosion protection. PTFE, 25% glass filled, slide plates are bonded to the top of the load flange to reduce the friction caused by lateral movement. The variables range from 9.5″ to 11.5″ in height and are designed for a travel range of 1/8″ upward to 3/16″ downward. To ensure quality, standard load testing was performed prior to shipping.

PTFE Slide Plates Designed for an Oil Refinery in Texas

PT&P custom designed PTFE slide plates for an oil refinery in Texas. These slide plate assemblies are comprised of 3/32″ thick 25% glass filled (PTFE) slide plates bonded to hot dipped galvanized carbon steel backing plates. The assemblies measure 47-1/2″ long by 36-1/2″ wide and 45″ long by 16″ wide. PTFE material provides a low coefficient of friction, is easy to install, does not require surface treatments, or grouting, and is unaffected by weather conditions.

Custom Designed PTFE Slide Plate and Pipe Shoe Assemblies

These custom designed PTFE slide plate and pipe shoe assemblies are fabricated from A 516 Gr. 70 carbon steel and painted to protect against corrosion. The slide plates are comprised of 3/32″ PTFE, 25% glass filled material bonded to 10 gauge backing plates. A total of twenty guided cradle supports were designed for pipes ranging in diameter from 8″ to 30″.
