Aluminum alloys include high amounts of aluminum. Additionally, this alloy comprises manganese, silicon, tin, copper, zinc, and magnesium. Aluminum alloy's remarkable properties make it the most demanding alloy in industrial applications. Because of its superior properties, this alloy is used in a wide range of sectors. Aluminum alloys shield the surface from the damaging elements outside and have exceptional corrosion resistance. This metal is lightweight and has good electrical and thermal conductivity. Aluminum Alloy Flanges constructed from this alloy have good features such as formability, weldability, malleability, tensile strength, and others.

Aluminum flanges are widely used in a variety of industrial applications. These flanges are used in a wide range of sectors, including paper, oil and gas, pharmaceuticals, fertilizers, food and dairy, petrochemicals, chemicals, and desalination facilities. These flanges are also used in nuclear power plants, electric power plants, water system pipe projects, and more. Following manufacture, these flanges are tested for rigorous quality inspections to ensure their long-term durability. This is accomplished using a variety of tests, including PMI, IGC, hardness, tensile, chemical, mechanical, micro, and macro.

Aluminium Flanges Marking

Every Standards have clearly requirements for steel flanges’ marking style, usually the marking words include seller’s Logo, buyer’s Logo (OEM), standard number, flange’s type, flange’s pressure, flange’s size, flange’s material, place of origin, heat number and other words for convenient to trace. If the flanges repaired by welding, it must mark on flanges showing this flange repared by welding. If the flange’s dimensions (OD, ID, PCD, Thickness, Holes number, Holes diameter, Tolerance etc) are different with the normal standard, it also must mark on flanges where it is different with normal ones. Another important place is heat number marking, it is the tracing base for every piece flange, and from the heat number we can trace to the beginning of raw material import.

The Marking Style for European Standards Flanges, DIN, UNI, EN 1092-1 norms etc
LOGO, EN 1092-1, TYPE 01, PN16, DN80, 88.9, P265GH, HEAT NUMBER
