ASTM A350 LF6 flange advantages
The ASTM A350 LF6 flanges are intended to be used in low-temperature services. The chemical composition of the material makes them ideal to be used in applications that take place in lower temperature environments. Note that, the operating temperature of ASTM A350 LF6 flange can go as low as -28 degrees C. The major advantages of the The ASTM A350 LF6 pipe flanges are:

  • They help to connect the piping system.
  • They help in easy repair of the piping system.
  • They can be assembled very easily and there is no need for welding.

These flanges are available in different types of faces and ideal for pipe sizes ranging from NPS ½ to NPS 24.

ASME SA 350 LF6 CL2 material properties
The ASME SA 350 LF6 CL2 material is basically a carbon steel or a low alloy steel. They are available in a wide range of surface finishes and they are popularly used for manufacturing gaskets. Different types of gaskets and flanges are made with the material, and they are used for various purposes according to their structure. They are perfect for low temperature services. They have a good tensile strength, yield strength, and they come with a minimum elongation of 20%. They are hard, sturdy, and have good longevity. They are available in various pressure ratings ranging between class 150 to class 2500.

A350 LF6 forged ring uses
The A350 LF6 forged rings are used in a wide range of applications. One can find them in different types of machinery and equipment. They are also found in pipes, valves and various other hardware. They are basically a ready-made base plate which is hot-rolled into the shape of a ring for meeting the specific dimensions of a base plate. They come with enhanced strength and durability. They are reliable and easily replaceable too. They can easily be exposed to low temperature applications, and they would work perfectly well for long durations.
