This universal expansion joint is designed with 5″ thick refractory-lining for a 52″ pipe in a Styrene Plant in Thailand. It measures 154″ long and is fabricated with ASTMA 304H stainless steel pipe ends and Incoloy 800H bellows. The expansion joint is designed for a lateral movement of 6.982″ with a design pressure of 30 psig at 1085°F. The bellows and pipe longitudinal seams and the pipe circumferential welds were x-rayed. All welds were also dye penetrant examined. A pneumatic test between the plies at 15 psig and the complete expansion joint at 45 psig was performed. The carbon steel surfaces were coated with a special three-coat paint system after testing and prior to shipment.

Duct Work for Absorbing Tower Piping in an Acid Plant
This duct work was fabricated with mitered elbows from SA-516 grade 70 carbon steel, and was designed for absorbing tower piping in an acid plant. It has a 72″ outside diameter and measures 23″-2/4″ from the centerline, elbow to elbow. This assembly was only a single portion of a duct work system that included 36″, 48″ and 60″ diameter sections of fabricated duct work. The duct work was fabricated with roundness tolerance of +/- 1/8″. A 100% dye penetrant test, soap and air test, and spot x-ray testing of all pipe circumferential and long seam welds was performed prior to shipment.
