Because of its low cost and anti-corrosion characteristics, welded and seamless stainless steel instrumentation tubing has become ubiquitous in industrial applications. At MillCorp Industrial Sales, LLC, we are a leading provider of stainless steel tubing to customers in the South and West Texas regions. We specialize in seamless and welded instrumentation tubing and offer it in the most popular diameters and lengths. Tubing is available in 3/16” to 5/8” diameters and in custom cut lengths or coils from 100’ to 25,000’. Other specifications such as austenitic, ferritic, and precipitation hardening are also available, as well as polishing, pickling, bright annealing, and a number of end finishes. We also offer tubing in duplex and high nickel/high performance alloys, all of which is fully qualified.
