Low Temperature Carbon Steel Pipe Flanges

Low temperature carbon steel pipe flanges are specifically designed for piping systems operating in sub-zero environments where standard carbon steel materials may become brittle.

ASTM A350 LF2 Forged Flanges Manufacturer & Supplier

SSMALLOYS manufactures and supplies Low Temperature Carbon Steel Pipe Flanges designed for applications requiring excellent toughness and reliable performance in sub-zero environments. Our forged LTCS flanges are produced from premium ASTM A350 LF2, LF3, En LF6 materials, making them ideal for LNG plants, cryogenic systems, offshore platforms, refineries, and low-temperature piping systems.

Manufactured in accordance with ASME B16.5, ASME B16.47, EN 1092-1, and other international standards, our flanges provide exceptional mechanical strength, dimensional accuracy, and long service life.

Low temperature carbon steel (LTCS) flanges are forged flanges manufactured from steels that have been impact-tested to ensure sufficient toughness at low operating temperatures.

Unlike ASTM A105 flanges, LTCS flanges maintain their mechanical properties in cold service, reducing the risk of brittle fracture.

Typical service temperatures range from:

0°C to -46°C
Down to -60°C (special applications)
Even lower for certain nickel-alloy grades

FAQs

What material is commonly used for low-temperature carbon steel flanges?

ASTM A350 LF2 is the most widely used forged carbon steel material for low-temperature applications due to its excellent toughness and mandatory impact testing requirements.

What is the minimum service temperature for ASTM A350 LF2 flanges?

ASTM A350 LF2 flanges are typically suitable for service down to -46°C (-50°F), depending on the design code and project specifications.

Do low-temperature flanges require impact testing?

Yes. ASTM A350 materials generally require Charpy V-Notch impact testing to verify toughness at the specified minimum design temperature.

Can ASTM A105 flanges be used in low-temperature service?

ASTM A105 flanges are intended for ambient and moderate-temperature applications. For temperatures below freezing or in cryogenic service, ASTM A350 LF2 or other low-temperature materials are generally recommended.

Can SSMALLOYS manufacture custom low-temperature flanges?

Yes. We provide OEM manufacturing, custom dimensions, special drilling, non-standard forgings, and project-specific solutions based on customer drawings and specifications.
