Piping Technology & Products, Inc. designed and fabricated several pipe shoes with loads up to 75,000 lbs. respectively, for a 750MW power plant in Alabama.
The shoes are to support the cooling towers’ circulatory water system at the power plant. The majority of the shoes were designed for a 60″ line and 50,000 lb. load, and the remaining few were designed for a 78″ line and 75,000 lbs. of load. After extensive engineering hours and structure analysis, PT&P’s engineering department was able to produce a detailed design and 3-D model for the supports that would allow them to run electronic interface checks.
Sweco Fab, the ASME fabrication shop of Piping Technology & Products, Inc., specially designed and manufactured two 20″ OD x 36″ long, suction strainers for a chemical plant in Louisiana.
The strainers, which were fabricated from SS32, each weigh 1,300 pounds. They were designed at 300 psig and 600° F and built to ASME code. In order to insure quality of the welds, PT&P’s Q.C. inspectors 100% x-ray tested butt welds of longitudinal seams and circumference seams, head to shell. Other pressure containment welds were dye penetrant examined. The unit, as a whole, was hydrotested at 390 PSIG.

Piping Technology & Products, Inc., custom designed and fabricated a collection of constants for an oil refinery in New Jersey. This application required the use of suspended constants, 100-C and base constants, 200-F.
In order to support the lines at the oil refinery, PT&P designed the 100-C constant spring hangers (vertical constants suspended from beams) at two different loads and total travels. The 100-C constant with a load of 105,000-lbs. and total travel of 6″ (figure 1) is set to travel 1-3/4″ down and 1-15/16″ up. It is 38-3/8″ in width, 79-1/4″ in height and furnished with a double lug suspension to allow it to hang from a double point suspension beam.
In comparison to the aforementioned constant, this particular 100-C constant spring hanger (figure 2) has a load of 33,000 lbs. and a total travel of 4-1/2″, 3/8″ up and 1-1/2″ down. This specific constant is 24-1/4″ in width, 71″ in height and also furnished with a double lug suspension to suspend from a double point suspension beam. Although the dimensions of these two constants are similar, the size of the springs and cams are very different.
Opposed to the 100-C constant, the 200-F constant spring hanger is a horizontal constant used to support piping from below. These 200-F constant spring hangers were designed with loads of 40,750 lbs. and total travels of 4-1/2″, 3/8″ up and 1-3/4″ down. These constants will be used in conjunction with sway struts to support pipelines at the oil refinery.

Piping Technology & Products, Inc., designed and fabricated over 1,000 standard pipe supports for a chemical agent disposal facility. These supports are to be used in a corrosive environment, therefore a unique, off white coating known as chemical resistant epoxy was used to cover the carbon steel, structural members.
The hardware was hot dipped galvanized, but in some cases, the u-bolts were coated with neoprene. Frames, guides, cantilever and axial stop supports comprised of the bulk of the material, however other support assembly components included rod hangers, clamped shoes and riser clamps.

PT&P Utilizes 3D-Modeling Technology to Design Pipe Supports for a 750MW Power Plant
Piping Technology & Products, Inc. recently designed and fabricated 9 pipe supports with loads up to 75,000 lbs. for a 750MW power plant in Alabama. After extensive engineering hours and structure analysis, PT&P’s engineering department produced a detailed design and 3-D model for the supports that would allow them to run electronic interface checks. The supports are to support the cooling towers’ circulatory water system at the power plant. Six of the 9 supports were designed for a 60” line and 50,000 lb. load, and the remaining 3 were designed for a 78” line and 75,000 lbs. of load.
Furnace Springs Versus Standard Springs The major differences between standard springs and furnace springs are their construction and intended use. Furnace springs operate in much the same way as other variable spring supports. They are designed to support the pipe and tubes that are subject to vertical thermal movement. The design changes come about because, furnace springs are exposed to extreme temperatures.
Red oxide primer in order to aviod potential hazards when exposed to high temperatures
Hot dipped galvanizedwhich tends to melt the zinc coating. Molten zinc can damage surrounding pipe and equipment.
Unique to its application and intended use
Welded design for housing assembly
Centers the spring coils within the housing and accommodates lug attachments
Bolted configuration for the housing
Spring used as a means to determine the loading of the catalyst tubes
