Product details
Material Grades & Specifications
Material selection is critical for ensuring the flange can withstand the environmental conditions of the pipeline.
  • ASTM A105: The most common grade for forged carbon steel flanges. It is suitable for ambient and high-temperature service in pressure systems.
  • ASTM A350 LF2: Specifically designed for low-temperature applications, maintaining its toughness and durability in cold environments.
  • ASTM A694: A higher-strength grade used primarily in high-pressure oil and gas transmission.
  • ASTM A516: Often used for plate flanges in moderate to lower temperature services.
Pressure Ratings & Standards
Flanges are classified by their pressure-temperature capability, adhering to standards like ASME B16.5 for smaller sizes (up to 24") and ASME B16.47 for larger diameters.
  • Standard Classes: Common pressure ratings include Class 150, 300, 400, 600, 900, 1500, and 2500.
  • Temperature Impact: As temperature increases, the allowable pressure a flange can withstand decreases. For example, a Class 150 A105 flange is rated for 285 psi at 100°F but only 150 psi at 500°F.

Frequently asked by buyers
Which carbon steel flange type is best for high-pressure and high-temperature service?

Weld Neck Flange (WNRF) is the best choice because its tapered hub provides superior stress distribution and strong butt-welded connection integrity.

When should a Carbon Steel Blind Flange be used?

A Blind Flange is used to seal the end of a pipeline, pressure vessel opening, or unused branch connection.

What is the difference between ASTM A105 and ASTM A350 LF2 carbon steel flanges?

ASTM A105 is commonly used for ambient and elevated temperature service, while ASTM A350 LF2 is designed for low-temperature applications where impact toughness is important.

Which flange type is easier to install in low-pressure systems?

Slip-On Flanges are easier to align and install, making them common in low-pressure piping systems.

What pressure standards are available for this carbon steel flange?

The flange is available in standard classes including Class 150, 300, 400, 600, 900, 1500, and 2500, depending on application requirements.

Is this flange suitable for oil and gas transmission lines?

Yes, especially when specified in higher-strength grades such as ASTM A694 for high-pressure transmission service.
