T6060 aluminium pipe with a raw finish. The 3 mm wall thickness makes it very well suited to welding up bespoke applications. After welding it is advisable to polish or paint the part to prevent tarnishing and oxidation. For a neat and secure pipe end, a connecting sleeve can be cut in half and welded on. Very high quality. These bends have a long centreline radius, which is the better choice over short-radius bends where space allows. Pipes with a larger radius have better flow characteristics than short-radius bends.
