Various Support Assemblies for a Power Generation Facility

Piping Technology & Products, Inc. designed and manufactured 85 support assemblies for a power generation facility in Georgia.   These assemblies consisted of Variable and Constant Assemblies and structures made with carbon steel and alloy material. The variable spring hanger assemblies have standard three-bolt clamps and lug attachments for the existing pipes. These variable spring hangers accommodate operating loads varying from 8,000 to 18,000 lb. and 1-1/2 " of upward travel. PT&P also manufactured a Fig.43 (heavy duty yoke u-bolt) for a 14" diameter pipe. Components of the Fig. 43 include yoke, U-bolt, shield, and lug. The structure (beam, plate, angle, and tube steel) was painted green as per the customer’s specifications.

17,000 lbs. Upthrust Constants for a Construction Site

Piping Technology & Products, Inc. designed and manufactured sixty nine Upthrust Constants for a construction site in Chad, Africa.  They range in constant size from 31-61 and are composed of A36 carbon steel. The applicable loads and travel for these constants are from 1,700 lbs.-17,000 lbs. and 3”-8”, respectively. The installed height for this job was much higher than our standard constants, so we had to customize them. By extending the height of our standard constant with an additional angle we were able to meet the installed height.

Variable Assemblies with Pre-Insulated Pipe Clamps

Piping Technology & Products, Inc. designed and manufactured several variable assemblies with pre-insulated pipe clamps for a chemical company in Texas. These assemblies are constructed of galvanized carbon steel hangers and hardware with Marinite® insulation.  The fabricated clamps range in size from 10" to 30", insulation thickness of 1" to 8" and with spring hanger sizes 80-180 standard, double, and triple variable spring hangers.

58 Large Diameter Floating Rings for a Refinery in Saudi Arabia

58 Large Diameter Floating Rings

Welding a Large Diameter Floating Ring

Sweco Fab, Inc. recently designed and fabricated 58 floating rings for a Refinery in Saudi Arabia. Ranging from 40"- 155" in diameter and 12"- 18" in height, these rings weigh more than 1,500 lbs. each and are made from SA240-316H stainless steel plate with thickness of 1/2" - 1 1/2". All rings are fabricated by Full Penetration Weld and examined by dye penetration test.

14,000 lbs. Load Hydraulic Shock Snubbers

Piping Technology & Products recently designed and manufactured four fig. 2100 hydraulic shock snubbers for a refinery in California. Carbon steel was used to manufacture these snubbers. They support a maximum load of 14,000 lbs., have a 3” cylinder, and 5” stroke load.  This was a custom job where the customer provided the figure number, cylinder size, and stroke load; we built the snubbers according to these specifications.

200 U-Type Constants with 46" of Travel

Inspecting the Constant Spring Supports

Piping Technology & Products, Inc. recently designed and manufactured 200 U-Type upthrust constants for a geothermal plant in Hawaii. The constant pictured on the left has frame dimensions of W 40" x H 75" x L 142", a constant load of 9,888 lb. to 10,239 lb. and a design travel of 46". It also utilizes rollers and PTFE, 25% glass filled slide plates to reduce the friction resulting from axial movements. All the constants in this project are composed of A36 carbon steel. Standard load testing and travel testing were conducted prior to shippment.

Special Application Variable Springs and Constant Supports

The three pictures above show materials being crated for shipment overseas. At the top center are pallets of variable springs designed for 10” of movement and 1000 pound load. This unusual combination of requirements is satisfied by an unusually long coil. This project required 700 of these variables. At the bottom center are constant supports designed for 14” of movement with loads near 2000 pounds. This large movement, unusual for this load, requires the large arc seen in the frame of the constant body. Two hundred of these constants were required. These spring supports are painted with a shop prime.

Pipe Shoes and Stand Assemblies for a Cross-Generating Station

Piping Technology & Products, Inc. recently designed and manufactured 46 of these support assemblies for a cross-generating power station in South Carolina.  These pipe shoes and assemblies are composed of carbon steel and accommodate pipe with diameters ranging in size from 18”-32”. All of these components are strong enough to support maximum installed loads of 8,000 lbs.
