Sweco Fab., a division of PT&P, fabricated a water treatment vessel from 3/8″ thick SA516 Grade 70 carbon steel for a refining facility in Texas. This pressure vessel has an 84″ outside diameter, is 11′ tangent to tangent and has an overall height of 14′-8″. It is designed for maximum working pressure of 100 psig at 100°F. A radiography test and hydrotest at 130 psig, held for 1 hour was conducted prior to shipment.

PT&P’s Sweco Fab division designed and manufactured a pig launcher and receiver with a flag type indicator and a flanged HI-T Pig Alert pig signaler. They are fabricated from carbon steel with a three coat paint system. The pig launcher has an 8” diameter minor barrel, a 10” diameter major barrel, and is 110” in overall length. The pig receiver has a 10” major barrel, a GD II closure and is 170” in overall length. They are designed for 430 psig at 100°F and were hydro-tested at 645 psig , held for four hours. Both pig launcher and receiver went through a 100% radiography test prior to shipment.

The pig launchers and receivers were designed for a coal-bed methane gas production facility in Colorado. They are equipped with an integral safety locking system, which works on the principle of mechanical key interlocking (transfer of keys). This system avoids serious injuries from human error and insures safety of personnel.
One starter key per launcher/receiver is kept in a box located in the control room. Each lock is executed with two keys. When the first valve is opened with this starter key, it releases the second key. This key is transferred to the next valve, which releases the second key from that valve, and so on and so forth. This process guides the operator through the specified sequence for opening and closing valves with a unique key for each step.

Piping Technology & Products recently completed the fabrication of a specialized ASME pressure vessel designed for a major Beaumont chemical plant. This project highlights our ability to deliver critical infrastructure that meets rigorous safety and performance standards within the petrochemical industry.
The core of this project was a heavy-duty piping vessel engineered to meet specific high-pressure chemical processing requirements. Due to the critical nature of the application, the pipe vessel underwent precise fabrication and extensive non-destructive testing to ensure compliance with all ASME code requirements before shipment.
In addition to the vessel shell, the project required complex integration of the vessel piping. These connections and nozzles were strategically fabricated to ensure seamless alignment with the plant’s existing infrastructure. By delivering this robust solution, we ensured that the Beaumont chemical plant could maintain operational efficiency with a fully compliant, high-performance system.
Unlike standard fabricators who supply standalone components, we engineer the complete pipe vessel system: from the high-pressure shell to the complex vessel piping connections. We deliver fully code-compliant, custom solutions that ensure seamless integration with existing infrastructure, minimizing downtime across nearby Texas chemical plants and global facilities.
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.

This high pressure knock-out drum has a 2.5″ thick shell fabricated from ASTM SA516 Grade 70, and a SA105 and SA350 carbon steel flange. The drum has a 48″ diameter, a total length of 15’8″ and weighs over 23,000 lb. It underwent a hydro-test and design test per ASME section VIII-1 “U” stamp vessel prior to shipment.

Sweco Fab, a subsidiary of Piping Technology & Products, recently completed the fabrication of a critical order of precision-engineered spectacle blinds:
We offer spectacle blinds in standard pressure classes (CL. 150, 300, 600, 900, 1500, 2500). Custom designs are also available, engineered to ASME B31.3 and based on your specific design pressure and temperature requirements.
Designed for rigorous process piping applications, these heavy-duty pipeline blinds provide a fail-safe mechanism for positive line isolation during maintenance and shutdown operations.
Spectacle blinds, also known as a figure, are essential safety devices used in piping systems where leakage past a valve could create hazardous conditions. Designed to provide positive line isolation during maintenance and shutdown operations, these heavy-duty components serve as a reliable, fail-safe barrier.
Each spectacle blind is fabricated to precise tolerances to ensure a proper seal between flanges. Whether positioned in the “open” configuration to allow flow or rotated to the “closed” position to block the line, the assembly provides clear visual confirmation of system status, enhancing operational safety and compliance.
As a specialized subsidiary of Piping Technology & Products, Sweco Fab delivers more than just standard metal fabrication. The Sweco team provides ASME-code-compliant, turnkey isolation solutions engineered for performance, reliability, and rapid delivery.
Sweco Fab provides a range of process piping components, such as spectacle blinds, line blinds, bleed rings, orifice plates, and strainers, in various alloys. Quick turnaround on both standard and custom components distinguishes Sweco Fab from commodity suppliers—ensuring clients meet the highest standards of containment, safety, and operational efficiency.

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.
