We have years of experience working as a flange manufacturer and ,since our establishment, have machined nearly every kind of flange out there. One of our most requested flanges would most likely be the weld neck flange. Larger applications with high-pressure needs require a weld neck flange. We also handle slip on flanges. These are the alternative to weld neck flanges as they make it easy to weld the outer diameter of a pipe. Our experts can also help you with your blind flange, counter bore socket weld flange, threaded/companion flange and lap joint flange needs. If you have any questions regarding any of our flange types, please don’t hesitate to reach out to our helpful sales staff and customer service team.
