The Home of HASTELLOY® and HAYNES® alloys

Pipe and Tubing

haynes building Haynes Tubular Products, established in 1976 and located in Arcadia, Louisiana, is devoted exclusively to the production of the highest quality nickel, cobalt, and titanium pipe and tubing.

We are the premier choice in innovative solutions for demanding applications. Our welded and seamless high-performance alloy tubulars are manufactured to the exacting requirements of aerospace, gas turbine, chemical processing, power pollution control, oil and gas, refining, agricultural, pulp and paper, marine, and many other industries.

Seamless Pipe

Seamless pipe is covered under ASTM B622.

Seamless Tubing

Cold-worked seamless tubing is produced from billets by either trepanning or extrusion followed by pilgering and/or drawing.

HAYNES® Ti-3Al-2.5V alloy

Ti-3Al-2.5V alloy was developed for aircraft hydraulic and fuel systems transmission lines, primarily because of it’s high strength-to-weight ratio. This ratio proved to be a major design advantage when used for hydraulic tubing lines, providing required strength levels, but more importantly, reducing weight by as much as 43% when compared to stainless steel.

Welded Pipe

Welded pipe is formed, welded, solution heat-treated, and tested in accordance with appropriate specifications, such as ASTM B619.

Welded Tubing

Welded tubing is made from strip by forming, welding, sizing or cold-working, solution heat treating, and testing in accordance with the applicable specifications. The classes of welded tubing available as described in the ASTM B626 and the ASME specifications are as follows:

  • Class I- as welded and solution-annealed
  • Class III- welded and fully cold-reduced and welded and bead-worked

Bead-worked vs. welded and fully cold-reduced

Fully cold-reduced tubing is the cold reduction of both the weld seam and tube wall (parent material.) This reduction is generally 20% of the total area and achieves optimum metallurgical conditions. Bead-worked tubing is the cold reduction of the weld seam only, generally reducing the weld seam only by 2-10%. Fully cold-reduced and bead-worked tubular products are both covered by the same classes under ASTM B626.
