Stainless Steel Tubing

Dover Tubular Alloys maintains an extensive inventory of seamless tubing & welded pressure tubing.

Commonly referred to as instrumentation tubing, heat exchanger tubing, condenser tubing, boiler tubing, or general service tubing, this product is used throughout many end-use markets and industries. We inventory this material in many different varieties including: Domestic, DFARS, AML and import.   We also maintain several different surface conditions and tempers including OD Polish, Bright Annealed, Annealed & Pickled, and Unannealed.

At Dover Tubular, our focus is not just the “core sizes” that the other guys inventory but also the “in between” sizes and product grades that are not available from many other supply partners.
