ASTM A350 LF3 Flanges

ASTM A350 LF3 Flanges

Superior Quality SA-350 LF3 CL2 Blind Flange Manufacturer in India, Refer Pressure Rating of LF3 Carbon Steel Weld Neck Flanges

Flanges manufactured using the A350 LF3 Material have been designed for use in low temperature applications. Aside from being tested for tension, the specified carbon or low alloy steel A350 LF3 class 2 Pipe Flange needs to conform to the required values of tensile strength, yield strength as well as elongation. This grade of flanges, depending on the client’s requirements have also been tested for Impact. Which means that the steel material used to produce the ASTM A350 LF3 CL1 Flange has to conform to the required values as mentioned in the specification in terms of its minimum impact energy, temperature, along with the minimum equivalent absorbed energy. In addition to the above mentioned tests, there are mechanical parameters such as hardness and hydrostatic behaviour which are also tested. The ASTM A350 specified Carbon Steel A350 LF3 flange is often seen used in low temperature applications involving nuclear components, heat exchangers, oil and gas industries.

Besides following the mechanical and chemical requirements of the ASTM A350 specification, the produced ASTM A350 Gr LF3 Cl1 Blind Flange also takes into account both the heat and product analysis as well. After being forged, the ASTM A350 LF3 Flanges undergo heat treatment such as tempering, normalizing, quenching and precipitation heat treatment. In order to secure freedom from injurious piping and undue segregation, the SA 350 LF3 Flange has been sufficiently discarded.
