Type of product	Grade(s)	Technical requirements* according to
Titanium tubes and pipes	Ti and Ti alloy grades 1, 2, 3, 7, 9, 11, 12, 16, 17, 26 and 28	ASTM B337, ASTM B338, ASME SB338 NACE MRO 175-94 VdTÜV 230/2 Dimensional tolerances acc. to DIN 17861 D3/T3 or closer

Titanium tubes are light in weight, high in strength and have superior mechanical properties. It is widely used in heat exchange equipment, such as tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and delivery pipes. Many nuclear power industries use titanium tubes as standard tubes for their units.

 

Our titanium welded pipe is welded with a single continuous seam and is 100% X-ray and liquid penetration tested.

The table below provides and a overview to the tube and pipe range that we manufacture and supply. We also specify many orders against the NPS standard aswell as providing bespoke sizing. The choice of welded or seamless tubing is largely governed by the size of tube and the application it is to be used for. It is necessary to specify either welded or seamless along with titanium pipe surface treatment and manufacturing standard. Titanium tubes are available in both seamless and welded for with differing size ranges.

High-quality titanium products that stand the test of time

GNEE is a supplier of titanium tubing with focused inventory serving the aerospace industry, commercial and military markets. Titanium tubes are the ninth most abundant element and the seventh most abundant metal in the earth's crust. The combination of its low density (just over half that of steel) and its high strength is why the metal is increasingly favored for military and commercial aircraft. Alloying titanium tubes with elements such as aluminum and vanadium increases titanium's strength while retaining its weight advantage over steel.
