High-Definition Plasma Cutting combined with State of the Art Drilling and Precise Machining Applications

Product Name: Machined All Over and Drilled Tubesheet Requirement

The Specifics of the Job: Our customer needed two large diameter, heavy thickness 2205 Duplex Stainless Steel tubesheets for a critical heat exchanger project they are working on. This tubesheet was plasma cut in-house and then sent to our State-of-the-Art machine shop. Our craftsmen provided precision machining; finishing the OD to 56.500” and machining both faces down to 4.780”. The top and bottom edges of the OD were dressed with a step bevel to the customer’s requirements. Being able to dress and prep the edges of the OD the customer is one more step closer to fabrication, saving them time and money in-house.

Sandmeyer’s recent addition of our Quickmill Annihilator Machining® Center has allowed us to complete the tubesheet by drilling almost 700 holes through almost 5” thick duplex stainless steel. The holes were drilled to a tolerance of +/-.003, and finished with expansion grooves. Another example of how Sandmeyer can help your project by providing value-added services that compliment your capabilities.

Job Specifications:

• 5” Thick 2205
• 56.500” OD
• Machined All Over
• Raised Face with Bevel
• 692 Holes; 1.514 Diameter
• With 2 expansion grooves in each hole
