48 Sway Braces for a Refinery Expansion Project.

48 Sway Braces for a Refinery Expansion Project

48 Sway Braces for a Refinery Expansion Project

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.

Slide Plate Assemblies with Marinite® Insulation and Vibration Pads

Slide Plate Assemblies with Marinite® Insulation and Vibration Pads

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.

Neoprene Lining

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.

U-Type Constants with Rollers to Reduce Friction

Rollers

This constant utilizes sealed cam follower roller bearings in place of slide plates that are generally used between the moving table and stationary frame. The rollers help to reduce the friction on the table, reduce residual loads which improve constant deviation, and help to restrict table movement in horizontal directions. These U-Type constants are fabricated from A36 carbon steel with dimensions of 28″H x 37″L x 17″W. The boxing, bolting patterns and loading table location are custom designed per customer specifications. The design also includes a graphite plate bonded to the top of the load flange to reduce the friction between the constant load flange and the saddle support above it. The supports are designed to carry 3015 lb. of piping load with an upward travel of 6″. The constants underwent standard load and travel testing before being shipped to an energy plant.

48" Guided Pre-Insulated Pipe Supports for High Temperatures

48" Guided Pre-Insulated Pipe Supports for High Temperatures

Pipe Shields, Inc., a subsidiary of Piping Technology & Products, Inc., designed these pre-insulated supports for a pipe size of 48″. The clamp and base are fabricated from carbon steel that includes a hot dipped galvanized finish. The 4″ thick insulation is a high density calcium silicate. These guided supports allow for a maximum axial travel of plus or minus 4 1/2″ and have a vertical load rating of 7,100 lb. The operating temperature of the pipe may exceed 1,200ºF, therefore the hot shoes are designed for 1,700ºF. These heavy duty base mounted pipe supports are specially designed to be installed on four emergency diesel exhaust mufflers in a hospital.

C-Type Constant with Special Lugs

C-Type Constant with Special Lugs

This PT&P 100 C-Type constant spring support was designed in conjunction with special lugs to fit inside of a trolley. The lugs will provide for movement up and down, as well as extensive horizontal movement. This constant was fabricated entirely from A-36 carbon steel with a hot-dipped galvanize finish. The constant measures 16″ wide x 25″ long x 56″ high. It is designed to carry 16,164 lb. of piping load with a travel of 3 1/2″ downward. The lugs will fit within a trolley by a single pin connection. This configuration will prevent swinging by maintaining the constant in an upright position, which will ensure proper functionality and eliminate any load deviation.

These custom designed constants will be utilized for a heavy load of 109,000 lb. They are designed for a downward travel of 1 1/2″. In order to support the heavy load and low take-off, the constants are designed with an inner and outer spring coil with the outer coil measuring 56″L with a 18 3/4″ O.D. These U-Type constants are fabricated from A36 carbon steel with a hot-dipped galvanize finish.

The dimensions of the constant are 31″H x 90″L x 32″W. The image above shows a PTFE, 25% glass filled slide plate on top to reduce the friction between the constant load flange and the structure above the support. The constant also includes slide plates between the table and the frame of the constant to reduce the friction on the table and improve constant deviation.

120 3/8" Long Custom Variable Spring Supports with Four Individual Coils

120 3/8" Long Custom Variable Spring Supports with Four Individual Coils

These variable springs are custom designed from carbon steel material. The springs are fabricated with extra long housings to allow for a pre-compression lower than the standard. This ensured that the starting (cold) load of 26,745 lb. could be achieved. The springs are designed for a movement of 5.55″ downward, which would produce an operating load for each assembly of 38,305 lb. These springs are to be utilized in pairs together with a 22″ riser clamp to produce a 407″ total pipe hanger assembly length and an overall combined operating load of 76,610 lb.
