230 Chromoly Pipe Shoes & Clamps Custom-Designed for Service at a Natural Gas-Fed Ammonia Plant

PT&P custom-designed 230 Chromoly pipe shoes & clamps for service at a natural gas-fed ammonia plant. The pipe shoes are designed for 1″ to 42″ diameter pipelines and coated with red epoxy for high temperatures (above 750°F). Each pipe shoe design utilizes custom two-bolt pipe clamps manufactured from 387 GR. 11 CL 2 material. This design is especially useful when welding to the process pipe is prohibited. These shoes clamp around the pipe instead of welding to the pipe in order to support a given load. Special bolting is required for high temperatures utilizing A 193 GR. B16 bolting material. Quality assurance inspection was conducted prior to shipment.

Hold-Down Clamps for a Waste Disposal Facility

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.
