Gr1 Gr2 Seamless Piercing Titanium Tube ASTM B338

Gr1 Gr2 Seamless Piercing Titanium Tube ASTM B338

This round seamless titanium tube is made by piercing and cold rolling, then finished with pickling, and is supplied in Gr1 and Gr2 to ASTM B338. The tube comes with an outside diameter of 20 mm and a wall thickness of 1.2 mm, or in custom sizes, with a maximum overall length of 12 metres and plain, beveled or threaded ends. Purity is 99.5 percent minimum. Each batch can be supplied with an EN 10204 3.1B certificate, a 100 percent radiography test report and a third party inspection report from TUV, BV or SGS. Because titanium carries a dense oxide film on its surface, the tube stands up to acid, alkaline, neutral salt and oxidizing media better than stainless steel and most non ferrous metals.

Mechanical Behaviour

Industrial pure titanium tube combines useful strength with good plasticity. High purity titanium can reach an elongation of 50 to 60 percent and a reduction of area of 70 to 80 percent, and although its strength is low on its own, a small amount of interstitial impurity or alloying addition raises the mechanical properties sharply, so the finished tube is both strong and ductile. The strength to weight ratio is high: the tube is about as strong as steel while weighing only some 57 percent of it. Heat resistance is good, with strength and stability held in air at 500 C, and low temperature performance is sound as well, since the tube keeps high impact strength even at minus 250 C and can take high pressure and vibration.

Applications

Typical duties include heat exchangers and condensers, power generation plant, gas processing, chemical processing vessels, specialty chemicals, sea water and desalination equipment, medical equipment and pulp and paper mills. Tube is packed with an environmental protection bag and shipped in a standard plywood case for export.
