Sweco Fab, Inc., a division of PT&P, fabricated a variety of six spectacle blinds that will be used for selective line isolation. The spectacle blinds are fabricated from A516-70 carbon steel with sizes ranging from 4″ to 14″ diameter and per ASME B16.48 code. The function of a spectacle blind is to allow a line to be in either full shut-off mode or full flow mode, depending on which side is being utilized. Spectacle blinds are a lower cost alternative to double block and bleed valves where OSHA requires positive isolation of piping segments for safety reasons.

The carbon steel sway braces for this project range in length from 88-3/8″ to 95-3/4″. The largest sway brace has an operating load of 18,000 lb., a design travel of 12″ in either compression or extension, and a spring rate of 1416 lb. per inch. The smallest sway brace has an operating load of 7000 lb., a design travel of 8″ in either compression or extension, and a spring rate of 1000 lb. per inch.
The anticipated loads and movements exceed those of the largest standard PT&P sway brace; therefore, these sway braces required a custom design and fabrication. Each of the 48 sway braces are configured with a unique combination of spring coils, housings, and internal components to accommodate the non-standard loads and movements.

The slide plate assemblies were fabricated from a combination of stainless steel for the low-friction sliding surface and 2-3/4″ Marinite® insulation to isolate the higher temperatures. A fabric reinforced isolator pad was placed between the slide plate and the I-beam for vibration control. The slide plates were tested for both load and heat transfer and will be utilized in a chemical plant.

Both pig launcher and receiver are fabricated from various low temperature carbon steels. They also include a GD Closure built to ASME Section VIII specifications. The operating temperature range is from -35°C to 65°C. The receiver is 33′ long and the launcher is 20′ long. Both have a 24″ diameter major barrel feeding into a 16″ diameter minor barrel. A rugged three coat paint system was applied per customer specifications. Various tests were performed, from hydrostatic and dye-penetrant to full radiography and ultrasound.

The riser clamps are 54″ in diameter and custom designed to be installed in the Emission Control Unit of a 1600 MW coal fired power plant in Texas. The clamps include neoprene lining adhesively bonded to the carbon steel to protect the FRP pipe. Prior to assembly, the riser clamps received a coat of Red Alkyd Primer to prevent rust and resist moisture and corrosion.

Piping Technology & Products, Inc. manufactured a variety of F-type variable springs with loads ranging from 526 lb. to 33723 lb. These variable springs are fabricated from a combination of carbon steel and A193-B7 CroMoly steel with A304 stainless steel slide plates. The variable springs are modified to include fully adjustable travel stops. The first purpose of the adjustable travel stops is to aid by distributing the load evenly during the installation process. The second purpose is to allow spring adjustment to any load within the operating range.
