ASTM A350 LF2 Flange
- Material: ASTM A350 LF2
- production: Slip on flange/WN flange/Long WN flange/Threaded flange/SW flange/Blind flange
- Production standards: ASME B16.5
PRODUCT DESCRIPTION
The steel flanges that are made from the ASTM A350 LF2 material come in various shapes, sizes, and thicknesses. The most common types of flanges include Weld Neck(WN) Flange, Slip-On(SO) Flange, Socket Weld(SW) Flange, Blind Flange, Threaded Flange, and Lap Joint Flange etc. These flanges are widely used in all kinds of pipelines, industries, and applications that require tight and secure connections. The ASTM A350 LF2 Flange is highly resistant to corrosion and can withstand high temperatures and pressures, making it an ideal choice for oil and gas pipelines, refineries, petrochemical plants, and many other industrial applications.

ASTM A350 is the Standard Specification for Carbon and Low-Alloy Steel Forgings, Requiring Notch Toughness Testing for Piping Components. The ASTM A350 LF2 Flange is manufactured according to the American Society for Testing and Materials (ASTM) standard specifications. ASTM A350 LF2 is a low-temperature carbon steel that is ideal for use in environments where temperatures can drop to -46°C.
