October 19, 2021

Compact Spring Supports Designed For 9K Load At An Oil Refinery

Type: Compact Spring Supports
Material: Carbon Steel w/ Hot-Dipped Galvanized (HDG)
Design: 9,000 lb. Load | +/-0.125″ Vertical Movement
Testing: Load Testing

PT&P custom-designed 76 compact spring supports or “disc spring” supports for a major oil refinery. This type of spring supports is ideal for locating under equipment flanges to limit excessive loads on sensitive equipment. PT&P has supplied custom compact springs for over a decade as the industry leader in plants all over the world. Compact springs are used for small travel systems to prevent equipment failures, assure safe plant operations, and reduce operational costs. Such springs can support loads equal loads to conventional springs while using 50% less space. If not addressed, pipe strain can cause misalignment, thermal expansion, and pipe-lift off resulting in strain on expensive equipment. For example in a typical refinery, upwards of $15M a year is spent on pump repair alone due to pipe strain issues. Compact springs are used in systems to support Centrifugal pumps and compressors, air-cooled heat exchangers, vessels, and steam turbines while addressing regulatory codes for API, ASME, UBC, and government compliance for organizations such as OSHA, EPA, WISHA, etc.

The springs are stainless steel Belleville washers and the housing is fabricated from A-36 carbon steel with a hot-dipped galvanized finish to protect against corrosion. The assemblies are 3″ high, designed to support a 9,000 load and movement of +/-.125″ (upward). Each assembly underwent load testing before shipment. Compact springs are specifically designed to minimize excessive loads on process equipment by managing nozzle loads and the flange seal and can be installed directly under the equipment. Another benefit of compact springs is to address corrosive environments (saltwater, marine air, or chemicals) by manufacturing them with metals like stainless steel and/or using amorphous glass coatings making them impervious to corrosion.

Hold-Down Pipe Clamps For A 20&Quot; 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.

August 24, 2021

Custom-Designed Bird Screens For Lng Service Provide A Humane Deterrent

PT&P custom-designed bird screens for a 3″ diameter pipeline at an LNG facility. Bird screens (or insect screens) are used on an open-ended pipe (i.e. exhaust) where birds or insects can be trapped inside the pipe creating a blockage. Birds such as pigeons and other roosting birds often build nests inside exposed piping and their droppings can carry diseases and even pose potential contamination and health hazards. Bird droppings have even been known to cause damage to sensitive equipment such as valves and gauges not to mention creating safety hazards on ladders, steps, and catwalks. It’s best to incorporate bird screens during the design of the refinery, chemical, power, LNG, or green energy plant and install them during construction. Our bird screens are fabricated from corrosion-resistant 304 stainless steel and can withstand temperatures up to 800 degrees Fahrenheit. They are designed to be easily assembled in the field without requiring a skilled welder or special equipment. PT&P can provide bird screens for any size piping or configuration.
