Piping Technology & Products, Inc. provided 35 stainless steel stanchions for pipe sizes 4 to 18 inches for a power company in Alabama.
The ends of the stanchions have shop-cut end connections that will allow field welding without any modifications by site personnel. Some stanchions were provided with straight pipe connections and others were provided with elbow connections. The minimum height requirement provided for a centerline height equal to approximately 16″ while the maximum pipe centerline was required to be at approximately 58 ½”. The stanchions were designed at 1100°F and sustained a maximum design load of 18,000 pounds. The stanchion base plates are 304 stainless steel and the tubes are constructed of A240 GR.304 seamless pipe.

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.

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.
