Hold-Down Clamps for a Waste Disposal Facility

September 4, 2021

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.

Cable Tray Support Rack Fabricated for a Groundwater Remediation

PT&P provided a cable tray support rack to a groundwater treatment facility in California. Groundwater remediation is a process whereby groundwater is purified by removing pollutants and containments rendering the water useful for crop irrigation and industrial processes. Groundwater remediation techniques can include but are not limited to, oxygen gas injection, dual-phase extraction, membrane separation, carbon absorption, and chemical oxidation. Cable trays, used in this facility, were designed to suspend electrical cables, wiring, and small-bore piping throughout the facility. Cable trays are also used in biochemical plants, solar power plants, sports stadiums, green energy plants, as well as, traditional plants such as petroleum refineries, chemical and coal-fired power plants. As a general rule, cable trays protect and carry cable and wiring from point “A” to “B” inside the facility.

This section of cable tray in the photograph (blue in color) is 25’ long, 7’ wide, and 11’ tall completely assembled. It is fabricated from carbon steel and painted with a highly chemically resistant epoxy mastic designed for immersion conditions to protect against corrosion in marine or industrial conditions. PT&P can fabricate any combination of instrument stands and structural supports from floor mounts, wall mounts to secondary supports, and more. In addition, we have the capabilities to do what few other structural fabricators can do including:

– Complete Engineering designs including FEA (Ansys) and Structural Engineering (STAAD)
– Load Testing
– Incorporation of Contact Corrosion Solutions including TPI (half-round thermoplastic) and FRP
– Incorporation of Vibration Control Solutions
– Ability to fabricate with a wide variety of metals including all grades of Stainless and Nickel Super Alloys

PT&P has worked on and is working on some of the largest water remediation projects in the US where we have supplied expansion joints, variables, fire protection insulated supports, and structural pipe supports. Our ASME shop is large, local to the United States, and includes heavy-duty equipment and specially trained personnel with over 45 years of experience making this division of PT&P ideal for large-scale projects such as this structural support as we can leverage our massive manufacturing scale and expertise.

Custom-Designed Bird Screens for LNG Service Provide a Humane Deterrent

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.

Piping Technology & Products custom-designed constant spring supports for crude oil processing at one of the largest refineries in the world. Petroleum refineries change crude oil into products such as jet fuel, gasoline, polypropylene, polyethylene, propane, sulphur, carbon black feed, and diesel that can be used for transportation, heating, feedstocks for making other chemicals, generating electricity, renewable energy, and paving roads. Piping Technology and Products was awarded this project because we were the only engineering manufacturing firm vendor of constant spring manufacturers in the world that could both design, manufacture, and test these units for the unique design conditions. These constant springs will support loads ranging from 88,185 lb. to 143,300 lb. They are designed for temperatures up to 650°F, and movements of 0.39” up, 4.72” down, -2.36” up, and 0.39” down. The Type-C constants are 67” H x 21” W x 88.25” L and the Type-F constants are 85” H X 39.75” W x 86.56” L. The F-Type springs will include graphite slide plates and are designed to support the piping from below while allowing both lateral and axial movement. All constant assemblies underwent magnetic particle inspection of welds, travel, and compression tests. Additionally, a special “cramp test” was conducted on each spring coil. A “cramp test” is done by compressing the spring coil by a specified length for a specific period of time. This assures the spring’s functionally especially when a large “wire diameter” is used to manufacture the spring coil for these high loads. At Piping Technology and Products and our subsidiaries, we specialize in designing pipe supports, expansion joints, and insulated supports for unique applications involving products not readily available. Our products are used in the CDU (crude distillation units), hydrocracking units, RFCC (residual fluid catalytic cracking), naphtha hydrotreater, and hydrodesulfurization units (also known as alkylation unit), and sulphuric acid regeneration (SAR) units in refineries.
