Heavy-Duty Pipe Clamps For Service At A Coal-Fired Power Plant

These clamps were installed in a coal-fired power plant on the Ohio River and this plant features one of the largest smokestacks in the world at 1038 feet. For this plant, sub-bituminous coal is used in conjunction with steam turbine technology to generate thermal power with over 10k Gigawatts of output annually.

Heavy-duty pipe clamps are bolted around the pipe and connect to the remainder of the pipe hanger assembly. This assembly included a Fig. 30 Forged Turnbuckle, which is also available on Amazon as a stocked item. PT&P maintains an extensive inventory of pipe clamps required for pipe hangers and support assemblies. These Fig. 80 Three-Bolt Pipe Clamps are fabricated from carbon steel and for this project, the pipe clamps were painted with a red oxide primer. These pipe clamps are designed for 36” diameter pipelines and are recommended for suspension of cold pipelines or hotlines where little or no insulation is required and are capable of supporting both horizontal and vertical piping. A visual inspection test along with “sample pipe” dimensional checks were conducted prior to shipment.

Such clamps can be used in any type of piping system for various industries such as chemical, biofuel, food processing, and refining plants. We have the ability to get such products at your jobsite overnight given our pipe hanger hardware inventory of over 1 million pounds, our quick order system through Amazon, and 24/7 manufacturing and engineering support provided by our teams around the clock.

Do you need this exact pipe support? Skip the line and order our Standard Pipe Support Components on Amazon. From forged carbon steel turnbuckles and light or heavy 2-bolt, 3-bolt pipe clamps, riser clamps to long tangent u-bolts, we stock standard sizes for your quick-turn orders.

Sway Braces Designed to Absorb Pipeline Vibrations Leading into a Containment Shelter

Sway Braces Designed To Absorb Pipeline Vibrations Leading Into A Containment Shelter

PT&P manufactured Fig. 550B Sway Braces for preventing excessive loading on 12″ diameter flanged expansion joints leading into a containment shelter. The sway braces include our Fig. 30 Forged Turnbuckles, spring casing. and size 3 spring coils along with other internal components. They are fabricated from carbon steel, hot-dipped galvanized, and designed for a spring rate of 450 lb./in. These sway braces measure 91-3/8″ pin-to-pin and are suitable for full deflection forces from 200 to 1,800 lb. Initial pre-compressed spring forces are from 50 lb. to 450 lb. to dampen vibrations, oppose pipe sway and absorb shock forces.

Fig.550B Sway Braces

Sway braces are recommended for controlling vibration, absorbing shock loadings; guiding or restraining the movement of the pipe resulting from thermal expansion; bracing a pipeline against sway. The vibration control and sway brace is shipped and ready for installation. The rod coupling rotates with slight resistance and the tension test collar can be rotated by hand while holding the rod stationary.

The sway brace should be in the neutral position when the system is hot and operating, at which time the tension test collar should be hand tight. If it is not, the sway brace should be adjusted to the neutral position by use of the load coupling. The screws in the tension test collar need not be loosened, since they serve only to secure it to the load coupling.

Constant Supports Designed with Bronzphite® Slide Plates for Oil Refinery in China
April 4, 2022

These big-ton constant spring supports with Bronzphite® slide plates were designed for a 400 KTA light oil processing and utilization unit in Southeast Asia. The constants are designed for high loads and utilize self-lubricating bearing plates consisting of high-quality bronze and graphite-filled grooves. Bronzphite® can be used where temperatures are up to 1100°F and for high loads, low-velocity applications, and in places where the use of oil or grease is undesirable or unfeasible.

Big Ton Constant Supports Designed With Bronzphite® Slide Plates For Oil Refinery In China

PT&P custom-designed and manufactured a total of four big ton constant spring supports w/ Brozphite® slide plates for a 400 KTA light oil for a processing and utilization unit at one of the largest of largest oil refineries in China. In US refineries, crude oil still makes up a majority of what is produced today: Us Energy Info Admin Petroleum Supply

These constant assemblies were fabricated from carbon steel and hot-dipped galvanized for extra protection against corrosion. The bronze plate acts as the bearing surface, supporting heavy loads, while the graphite inserts provide a solid, oil-free sliding surface. They are designed for operating temperatures up to 1100°F and an operating load of 187,393 lb., with 1-1/2″ total travel.  It is through the combination of high-strength bearings and impregnated graphite that it is an ideal environment for maintaining excellent wear resistance and durability under severe operating conditions.  Load and travel testing was performed prior to shipment.

Bronzphite Slide Plate

For this particular crude oil production and mining facility, we also supplied other key products from our portfolio, including variables, snubbers, sway braces, and sway struts. Petroleum refineries change crude oil into products such as jet fuel, gasoline, polypropylene, polyethylene, propane, sulfur, carbon black feed, and diesel that can be used for transportation, heating, feedstocks for making other chemicals, generating electricity, renewable energy, and paving roads.

As an industry leader in the oil, gas, and petrochemical industries for over 47 years, we specialize in designing pipe supports, expansion joints, and insulated supports for unique applications involving both products readily available and products not readily available. Our products are used in the CDU (crude distillation units), hydrocracking units, RFCC (residual fluid catalytic cracking), naphtha hydrotreater, hydrodesulfurization units (also known as alkylation units), and sulphuric acid regeneration (SAR) units in refineries.
