A client approached Conrex Steel for fabrication of a stainless double knuckle cone. As a custom fabricator, this client knew we had the skills and the knowledge to produce exactly what they needed. We can fabricate segmental double knuckle cones beyond the formed only state, and in one course which eliminates one circumferential seam. Following the design and dimensions supplied by the customer, we pressed the segments from SA387, SA516, 304H stainless, and stainless clad. The double knuckle cones were fabricated by hot forming a blank to 15' long.

With our ability to form large individual pieces, we exceed the abilities of others in the industry. To learn more about this steel double knuckle cone fabrication project, please contact Conrex Steel today.
