Tubular products sizes for
and HASTELLOY® alloys
Seamless pipe is covered under ASTM B622.
Cold-worked seamless tubing is produced from
billets by either trepanning or extrusion followed by
pilgering and/or drawing.
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
Welded pipe is formed, welded, solution
heat-treated, and tested in accordance with
appropriate specifications, such as ASTM B619.
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:
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 class III. The class III designation covers cold-worked and solution annealed product*.

Haynes Tubular Products, established in 1976 and located in Arcadia, Louisiana, produces welded and seamless pipe and tubing. The Tubular facility has more than 36 years’ experience in producing HASTELLOY®, HAYNES® alloys and Titanium 3Al-2.5V tubular products.
Our 200,000 square tubular facility is located on approximately 42 acres of land houses a complete range of pilgering, welding and drawing equipment designed especially for the manufacture of diversified sizes of seamless and welded products in HAYNES®, HASTELLOY®, and titanium Ti-3AL-2.5V alloys.
The tubular uses feedstock produced from the Kokomo, Indiana mill to fabricate welded and seamless alloy pipe and tubing and purchases extruded tube hollows to produce seamless titanium tubing. Manufacturing processes at Arcadia require cold pilger mills, weld mills, draw benches, annealing furnaces and pickling facilities.
Our Manufacturing Equipment
• 9 Pilger mills
• 2 Draw benches
• 2 Continuous weld mills
• 1 Pipe mill
• 3 Vacuum furnaces
• 1 Continuous hearth furnace
• 3 UT testers for inspection
Our products exceed the most rigorous specifications and are trusted worldwide to provide exacting service requirements. We use state-of the art inspection equipment and methods to provide process control and ensure product integrity. Samples are tested for conformance to the chemical composition requirements of the applicable specification.
Consistent quality levels with optimum metallurgical conditions are sought by plant personnel when using welded tubular products. In theory, procurement to ASTM specifications should lead to assurance of consistent, well-defined metallurgical conditions. However, the ASTM specifications leave the option to the buyer to select between the cold working of the weld-metal only (bead working) or of cold working both the weld and the base metal (cold-reduction via drawing or pilgering). As such, additional detailed specifications are required to insure optimum metallurgical conditions for best resistance to corrosion.
