Detailed Information:
Different types, sizes, and ASTM A350 LF2 F orged Flanges classes exist. While the class 1 forged flange is the most widely used, the class 2 forged flange has a higher mechanical strength and is more suitable for applications. A350 LF2 Cl1 Flanges are available from Steel India Company and are class 2 flanges. The types of flanges also differ depending on the production method.
There are many applications where the SA350 Gr LF2 Forged Flange is used, such as when pipes transmit fluids and gases in rough conditions, but the material is primarily carbon steel. The specification is ASTM A350, and the dimensions vary according to the standard. The ASTM A350 LF2 Class 1 And Class 2 Flanges range in nominal bore sizes from 12 inches to 48 inches, with different types of faces available, such as flat faces, ring joints, and raised faces. The LF2 Class1 Flange is also available with varying classes of pressure and wall thicknesses that correspond to its different pressure capacities. In addition to 150, 300, and up to 2500, pressure numbers indicate the pressure capacities of A350 LF2 Class1 Flanges, ranging from PN6 to PN64 in pressure capacity. We make ASME SA 350 Gr LF2 Cl1 Flanges of carbon steel, a strong metal. The toughness of the metal translates into the high wear and tear properties of the ASME SA 350 Gr LF2 Cl1 Flanges and the increased wear and tear properties. Consequently, the flanges have a high-impact strength and a long life over time. If you would like more information on the different types, such as the A350 LF2 plate flanges and their complete price list, please do not hesitate to contact us.
A350 LF2 flanges are usually made from a low-carbon steel alloy, either forged or ring-rolled. They are available in various sizes, ranging from 1/2 inch to 24 inches in diameter. Their properties include maximum machinability, mod erate strength, and leakproof connections.
We make oil and gas pipelines and ASTM A350 LF2 Flanges from high-quality materials resistant to heat and pressure. Such flanges frequently appear in pipeline installations for natural gas and oil.
