Structural Supports for Vessels in an Oil Refinery in Texas

20 vessel supports ranging in length from 30″ to 84″ were manufactured for an oil refinery in Texas. The structural supports will be attached to existing vessels to assist in supporting the nearby pipes and piping system. The supports were fabricated from carbon steel and coated with a hot-dipped galvanize finish to prevent corrosion.

4″ to 14″ Diameter Spectacle Blinds for Process Piping

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.

Flue Gas Duct Damper
Flue Gas Duct Damper

This damper was fabricated from a combination of 304 stainless steel and Inconel®. It is designed as a shut-off damper to control the flow of flue gas in an ammonia plant. The damper will be connected to a motor-driven control system by the linkage shown in the picture. The overall dimensions are 10′ x 6′ with a weight of 2,200 lb. It was painted with standard inorganic zinc primer and top coat per customer specifications. The damper went through visual inspection, dye-penetrant, and functional testing before being shipped to the customer. Refractory lining, utilized to withstand the high temperatures, will be added during installation.

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.
