Variable Spring Supports for an Off-Shore Oil and Gas Refinery

January 5th, 2010 No comments
C-Type Variable Spring Support Assemblies

C-Type Variable Spring Support Assemblies

The C-Type variable spring assemblies range in overall length from 3′-2½” to 3′-5/8″, and the F-Type measures 1′-1½. The C-Type variables are designed with an operating load of 1653 lb. and a spring rate of 680 lb/in. The F-Type variable is designed with an operating load of 1511 lb. and a spring rate of 340 lb/in.

F-Type Variable Spring Support

F-Type Variable Spring Support

The variable supports will be utilized in a highly corrosive environment; therefore, Grade 316 stainless steel was used with a unique 3-coat paint system applied to the can housing.

5′ 7-1/2″ Tall F-Type Variable Spring Support Assemblies

5′ 7-1/2″ Tall F-Type Variable Spring Support Assemblies

PT&P designed and fabricated F-type variables for an oil refinery in California. The variable springs are designed for an operating load of 49,771 lb. and an installed load of 43,000 lb. Two coils are used in tandem to achieve a vertical movement of 1-5/8″ downward. The variables are fabricated from hot-dipped galvanized carbon steel and are customized with an extended load column to reach an installed height of 67-1/2″. The variables for this project are the largest standard double springs offered; however, PT&P can customize to any load specification. Standard load testing was performed prior to shipment.

48" I.D. ASME Code Process Vessel

48" I.D. ASME Code Process Vessel

This process vessel has an inside diameter of 48″ and measures 60″ tangent to tangent. The overall height of this vessel is 81″, and measures 120″ including the legs. It is fabricated from 1/2″ 516-70 carbon steel material. This vessel is designed and fabricated according to ASME Section VIII Div 1 codes. It has a capacity of 500 gallons with an internal design pressure of 50 PSIG. The maximum acceptable working pressure is 178 PSIG. This process vessel was heat treated for stress corrosion resistance in the field and 100% x-ray tested and hydro-tested at 231 PSIG prior to being shipped to the customer. This vessel was designed for the customer as a replacement vessel for one in the field that had already provided 20 years of service in a mildly corrosive environment.

Sweco Fab, Inc. worked with the customer to provide a vessel that was even more efficient than the previous one by including 1/8″ thicker walls, an additional 12″ between tangents, heat treatment, an internal drip plate, and an OSHA compliant ladder and platform.

Polyurethane Saddle Supports for FRP Pipe

Piping Technology & Products, Inc. designed and fabricated these saddle supports to support FRP pipe or similar plastics in sizes from 2″ to 36″ in diameter. The saddle support is fabricated from a molded density 20 polyurethane block with a load bearing capacity of 150 PSI that allows for high loads for a 36″ diameter line.

The base is bonded to a 20 gauge steel pan that provides a steel to steel resting surface. The foam is extended on each side of the base to allow field strapping of the support to the pipe. These saddle supports are often used in a circulating water service. These particular supports are to be used in a power generating station in the U.S.

7′- 6" Long Custom Variable Spring Hangers

November 21st, 2007 No comments
7'- 6" Long Custom Variable Spring Hangers

7'- 6" Long Custom Variable Spring Hangers

These variable spring hangers were custom designed per customer specifications for a power plant in Turkey. The pipe hanger assembly measures 7′- 6″ long and the diameter of the can measures 12″. The variable spring hanger is capable of 55,137 lb. of hot load and 63,339 lb. of cold load. The assembly allows for 1″ upward travel.

In order to achieve the required spring rate, PT&P utilized a set of stacked coils (5 5/8″ O.D.) nested inside a larger coil. This produced an overall spring rate of 9,235 lb/in. The upper and lower attachments were minimized to fit within the space requirements provided.

Base Insulated Supports

PT&P fabricated base insulated supports used to minimize thermal conductivity between the base and un-insulated lines. The support is designed with a carbon steel bottom and a stainless steel upper for cryogenic temperatures of -300°F. The insulation is made of 20 PCF polyurethane block. These supports are designed to handle lateral and axial pipe loads. They also include a wear pad for extra pipe reinforcement, which prevents local deformation of the pipe.
