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 it is pressure rated up to 5,000/PSI and has a 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 class III. The class III designation covers cold-worked and solution annealed product*.

haynes buildingHaynes 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.

Quality

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.
