About Carbon Steel Low Temperature Flanges

SKYLAND METAL AND ALLOYS INC.is one of the recommended manufacturers of Carbon Steel LF2 Flanges In India. ASTM A350 LF2 Flanges is composed of general Carbon steel and it is almost always supplied in conditions such as Quench and Tempered, Normalised and Tempered or Normalised. These types of flanges have moderate impact toughness and moderate strength. Regarding machining of A350 LF2 Flanges, these flanges exhibit excellent machinability, but the machinability of these flanges is based on various factors such as the conditions involved and various operations such as turning, milling, sawing, broaching, etc. Machining of flanges of A350 LF2 can be achieved by using the standard feeds and speeds that have been recommended by manufacturers of machine tools.

ASTM A350 LF2 flanges are in big demand in applications that use cold temperatures and do not need resistance to corrosion. Regarding the forging of these types of flanges, the temperature for forging should be in the range of 900 1200 o C. To avoid scaling from taking place, the soak times for flanges of A350 LF2 should be at a minimum. Yet, enough time should be allocated so as to allow the centre to reach furnace temperature. After the process of forging is over, the pieces that have been forged, should be allowed to cool down in still air. Flanges of A350 LF2 can be procured in Classes/Pressures of 2500#, PN16, 150#, PN64, PN10, 300#, PN25, 1500#, 600#, PN40, 900#, PN6, etc.

Reliable Performance in Extreme Temperatures

Designed for low temperature service, our flanges ensure tough resilience and operational safety from -46C up to +345C. The use of high-quality LF2, LF3, and LF1 carbon steel grades provides exceptional impact strength and resistance to brittle fracture, making them ideal for the oil, gas, and petrochemical industries.

Multiple Flange Types and Face Options

Choose from a wide range of flange types-Weld Neck, Slip-On, Blind, Socket Weld, Threaded, and Lap Joint-with face options including Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ). This versatility allows seamless integration into various piping systems, meeting diverse project requirements.

Superior Corrosion Resistance and Coating

Our flanges come with either a robust black paint or anti-corrosion oil finish, significantly extending their lifespan in corrosive environments. Combined with precise forging and anti-rust oil coating, they maintain performance and aesthetics even under the harshest industrial settings.

FAQ's of Carbon Steel Low Temperature Flanges:

Q: How are carbon steel low temperature flanges tested for quality?

A: Each flange is rigorously tested using ultrasonic, hydrostatic, positive material identification (PMI), and impact tests. These quality checks ensure the flanges meet ASME and EN standards for mechanical strength and material integrity, suitable for critical applications in oil, gas, and chemical plants.

Q: What applications are suitable for low temperature carbon steel flanges?

A: These flanges are ideal for industries such as oil & gas, chemical processing, power generation, and cryogenic services where both durability and performance in sub-zero and elevated temperatures are essential.

Q: When should I use an RTJ, RF, or FF face type?

A: Raised Face (RF) offers general-purpose sealing; Flat Face (FF) is used with cast iron or equipment with flat-faced flanges; and Ring Type Joint (RTJ) is chosen for high-pressure, high-temperature environments requiring a metal-to-metal seal.

Q: Where are your carbon steel low temperature flanges exported from?

A: We manufacture, supply, and export from India, serving global markets with reliable delivery supported by secure packaging in plywood cases or pallets to ensure quality upon arrival.

Q: What process ensures high corrosion resistance in these flanges?

A: The application of black paint and anti-corrosion oil provides a protective barrier against rust and environmental corrosion. This, combined with high purity steel and anti-rust oil coating, guarantees superior longevity in service.

Q: How do I select the right flange type for my project?

A: Your choice depends on the piping connection and pressure class requirements. Weld Neck is best suited for high-pressure or critical applications, while Slip-On is easier to install for moderate pressure. Socket Weld, Threaded, Blind, and Lap Joint types offer flexibility for varied installation needs.

Q: What benefits do these flanges offer over standard carbon steel flanges?

A: They provide enhanced low temperature toughness, high impact resistance, and superior corrosion protection, making them a reliable choice for demanding service conditions where safety and durability are paramount.
