ASTM A350 LF2 Flanges

The ASTM A350 LF2 grade flanges are general carbon steel flanges that possess excellent impact resistance. ASTM A350 LF2 Flanges are designed with a chemical content of carbon, silicon, manganese, phosphorous, sulfur, chromium, molybdenum, copper, niobium, and vanadium. This content allows them to possess good corrosion resistance properties across harsh conditions. The ASTM A350 Gr LF2 Forged Flange is a high-strength grade that is employed possessing lower surface porosity and a finer grain structure. These flanges also showcase higher ductility compared to processed steel. A350 LF2 Cl1 Material is designed with superior mechanical properties. They possess a tensile strength of 485 to 655mpa with a minimum yield strength of 250mpa and can be easily elongated by 30% in the system. The ASTM A350 Pipe Flange is a device that is employed to join piping componentsefficiently. These flanges provide strength and stability to different applications. They are designed to work in high as well as low-temperature setups. A350 Gr LF2 LTCS Flange possesses superior hardness at low temperatures and are very reliable.

The SA 350 LF2 Blind Flange is produced without any boring center or a lip. The flanges are used to seal the ends of piping components. They can be welded but are generally bolted in place, allowing room for repair and maintenance. A350 LF2 Weld Neck Flange is a high-strength component that possesses a larger lip or protruding hub that allows them to be utilized to provide stability to different piping equipment. The SA 350 LF2 Cl1 Long Weld Neck Flange has a slightly bigger neck than a standard weld neck flange. This allows them to be used in different high-pressure and temperature conditions. The SA 350 LF2 Class 1 Slip On Flange is one of the most common flangesused in the oil and gas industry that is easily slid on the piping grade and can be welded using a standard fillet weld. A SA 350 Gr LF2 Threaded Flange has threads that allow it to be wound to threads on subsequent modules. These flanges are used in applications where stress on the system is low. The ASTM A350 LF2 Cl1 Lap Joint Flange is made with a two-component assembly with a stub end and a ring-type lap joint allowing it to securely seal different components in place. A350 Gr LF2 Plate Flange is a flat circular disc that has grooves on its face allowing it to join different piping grades. The robust Sa350 LF2 Cl1 Loose plate flange is available across all our outlets at the best rates.
