6060 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is much more closely related to the alloy 6063 than to 6061.The main difference between 6060 and 6063 is that 6063 has a slightly higher magnesium content.
A 7 + 5 ⁄ 8 in (190 mm) production casing is set at a depth of about 15,000 ft (4,600 m) and a 5 in (130 mm) production liner set to TD. Probably, this well required a high mud weight at the bottom of the hole and cementing the 7 + 5 ⁄ 8 in (190 mm) casing at TD would have resulted in too much pressure and lost circulation.
On September 8, 2002, Michael R. Gordon and Judith Miller published a story in the New York Times titled "U.S. Says Hussein Intensifies Quest for A-Bomb Parts": In the last 14 months, Iraq has sought to buy thousands of specially designed aluminum tubes, which American officials believe were intended as components of centrifuges to enrich uranium.
T5 temper 6063 has an ultimate tensile strength of at least 140 MPa (20,000 psi) in thicknesses up to 13 millimetres (0.5 in), and 130 MPa (19,000 psi) from 13 mm (0.5 in) thick, and yield strength of at least 97 MPa (14,000 psi) up to 13 millimetres (0.5 in) and 90 MPa (13,000 psi) from13 to 25 mm (0.5 to 1 in). It has elongation of 8%.
A tube and pipe may be specified by standard pipe size designations, e.g., nominal pipe size, or by nominal outside or inside diameter and/or wall thickness. The actual dimensions of pipe are usually not the nominal dimensions: A 1-inch pipe will not actually measure 1 inch in either outside or inside diameter, whereas many types of tubing are ...
In tube hydroforming pressure is applied to the inside of a tube that is held by dies with the desired cross sections and forms. When the dies are closed, the tube ends are sealed by axial punches and the tube is filled with hydraulic fluid. The internal pressure can go up to a few thousand bars and it causes the tube to calibrate against the dies.
Production of one kilogram of aluminium requires 7 kilograms of oil energy equivalent, as compared to 1.5 kilograms for steel and 2 kilograms for plastic. [143] As of 2023, the world's largest producers of aluminium were China, Russia , India, Canada, and the United Arab Emirates , [ 141 ] while China is by far the top producer of aluminium ...
The pipe is coated with a 99.3% specular reflective film and the distribution element at the end of the light pipe consists of a 4.6 m long diffusing radial film with an 87% visible transmittance. The light pipe introduces consistently illuminance levels ranging between 300 and 2,500 lux throughout the year at distances between 7.6 m to 10 m. [12]
