Low Temperature Carbon Steel Flanges are designed to operate in environments where temperatures are significantly below standard ambient conditions. These flanges are used in industries where low temperatures can affect material performance, such as in cryogenic applications, cold weather pipelines, and certain industrial processes.Specifications and Standards for Low Temperature Carbon Steel Flanges1. Material Specifications:Low temperature carbon steel flanges are usually made from materials that are specifically treated or alloyed to retain strength and toughness at low temperatures. Key material specifications include:• ASTM A350 LF2: Standard specification for carbon and low-alloy steel forgings used for pressure vessels and piping at low temperatures.• ASTM A333: Specification for seamless and welded steel pipe for low-temperature service.Material Composition for ASTM A350 LF2:• Carbon: 0.26-0.34%• Manganese: 0.60-0.90%• Phosphorus: 0.035% max• Sulfur: 0.040% max• Silicon: 0.15-0.35%• Nickel: 0.40% max• Chromium: 0.30% max• Copper: 0.20% max2. Flange Types:Low temperature carbon steel flanges come in several types, each suited for different applications:• Weld Neck Flanges: Provides a strong, high-integrity weld connection. Ideal for low-temperature applications where the flange will be subject to thermal cycling.• Slip-On Flanges: Easier to align and install, typically used in less critical low-temperature applications.• Blind Flanges: Used to seal the end of a pipe or vessel; important in systems that are periodically opened for maintenance.• Socket Weld Flanges: Useful in smaller pipe sizes; the pipe is inserted into the socket of the flange and then welded.• Threaded Flanges: Not commonly used in extremely low temperatures due to the risk of leaks and reduced mechanical strength at low temperatures.3. Dimensions and Tolerances:• Dimensions: Adhere to standards such as ANSI B16.5 and ANSI B16.47, which provide detailed dimensioning for flanges, including bolt circle diameter, number of bolt holes, and bolt hole diameter.• Tolerances: Ensure that flanges meet dimensional tolerances for proper fit and function, which is crucial for maintaining integrity at low temperatures.4. Pressure Classes:Low temperature carbon steel flanges are available in various pressure classes, such as:• Class 150• Class 300• Class 600• Class 900• Class 1500• Class 2500The pressure class determines the maximum pressure rating of the flange at a given temperature.5. Standards and Codes:• ASME B16.5: Provides dimensions and pressure-temperature ratings for flanges and flanged fittings.• ASME B16.47: Covers large diameter flanges.o 2. SPECFICATIONS:• Manufacturing Range: DN 15 (1/2”) to DN 1500 (60”)• Rating/Class: 150/300/600/900/1500/2500 & PN 10/16/25/40/63/100 etc.• Dimension Standard: ANSI/ASME B16.5/B16.47/B16.36/B16.48/DIN/EN 1092-1, etc.• Face Finish: Raised Face (RF) Finish, Flat Face (FF) Finish, Ring Type Joint (RTJ) Finish• Material Type: LTCS: ASTM/ASME A350 LF2, ASME/ASTM A694 F42, F46, F52, F60, F65, F70

 A pipe flange connects piping and components in a piping system by use of bolted connections and gaskets. Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange).
The main use of flange is to connect pumps, pipes, valves, and other equipment to make a pipework system. Usually, flanges are threaded or welded, and you can connect two flanges by bolting them with gaskets and providing a seal that gives easy access to the piping system.

We are offering IBR Flanges to our clients.
Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels. A cover plate can be connected to create a "blind flange". Flanges are joined by bolting, and sealing is often completed with the use of gaskets or other methods.
