Carbon steel Flanges:

Carbon steel flanges are essential components in piping systems that connect pipes, valves, and other equipment. Our high-quality flanges provide a reliable and secure connection, ensuring the smooth flow of fluids and gases in various industries. Carbon steel flanges are specifically constructed from carbon and steel, which contains carbon as the primary alloying element.




  • Standards:









ASTM A105N (SA105N),

MSS SP-44,

DIN 2533.



  • Pressure ratings:





Class 150-2500



  • Standard dimensions.





Types of Carbon Steel Flanges:

Weld Neck Flanges: These flanges have a long-tapered hub, which provides reinforcement and stability. They are commonly used in high-pressure and high-temperature applications.

  • Material: Carbon, Alloy, and Stainless Steel
  • Standards: ASTM A105, ASTM A182
  • Sizes: 1/2'' to 24'', Customized up to 48''
  • Pressure Ratings: Class 150 to 2500

Slip-On Flanges: These flanges have a slightly larger diameter than the pipe, allowing them to slide over the pipe. They are easy to install and are suitable for low-pressure applications.

  • Standard: ASTM A105, ASTM A182
  • Material: Carbon Steel, Alloy Steel, Stainless Steel
  • Size: 1/2'' to 24'', customized up to 60''
  • Pressure Ratings: Class 150 to Class 2500

Blind Flanges: These flanges are solid discs that are used to close off the ends of pipes or valves. They are commonly used in systems where future connections may be required.

  • Material: Carbon, Alloy, and Stainless Steel
  • Standards: ASTM A105, ASTM A182
  • Sizes: 1/2'' to 24'', Customized up to 48''
  • Pressure Ratings: Class 150 to 2500

Threaded Flanges: These flanges have internal threads that allow them to be screwed onto the pipe. They are commonly used in low-pressure applications and where disassembly may be required.

  • Standard: ASTM A105, ASTM A182
  • Material: Carbon Steel, Stainless Steel, Alloy Steel
  • Size Range: 1/2'', 1'', 2'', 3'', 4'' to 24''
  • Pressure Class: Class 150 to 2500

Socket Weld Flanges: These flanges have a socket-like end that fits over the pipe, creating a strong and leak-resistant connection. They are commonly used in small pipe sizes and high-pressure applications.

  • Standard Carbon steel ASTM A105, ASTM A350 LF1/2, ASTM A181
  • Pressure Ratings: Class 150 to Class 2500

Lap Joint Flanges: These flanges are used in conjunction with stub ends, allowing for easy alignment of the bolt holes. They are commonly used in systems requiring frequent disassembly.

  • Carbon steel: ASTM A105, A350 LF2
  • Pressure Ratings: Class 150 to Class 2500


Benefits of Using Carbon Steel Flanges (cs pipe flanges):

  •  Strength and Durability: Carbon steel flanges offer excellent strength and durability, making them suitable for demanding industrial applications. They can withstand high pressure and temperature conditions.
  • Corrosion and Resistance: Carbon steel flanges can be coated or lined to enhance their resistance to corrosion, protecting them from environmental factors and extending their lifespan.
  • Versatility: Carbon steel flanges are available in various sizes, pressure ratings, and types, making them versatile for different piping system requirements.
  • Cost-Effective: Carbon steel flanges are generally more affordable compared to flanges made from other materials, making them a cost-effective choice for many industrial applications.
  • Easy Installation and Maintenance: Carbon steel flanges are designed for easy installation and maintenance. They can be quickly and securely connected, reducing downtime and maintenance costs.
