Carbon Steel Flanges
Our company provides Carbon Steel Flanges.
Carbon steel pipe flanges usually adopt mild steel or low carbon steel, as it includes a small percentage of carbon, strong and tough but not readily tempered.
Carbon Steel Flange and end flange connectors are basically made of carbon steel. Common standards include ASTM A694, ASTM A105N (SA105N), MSS SP-44, DIN 2533. Accompanying pressure ratings are from class 150 to 2500.

Carbon Steel Flanges
Carbon Steel Flanges are one such type of flange that is usually made up of carbon steel. This material provides properties such as resistance to corrosion, excellent durability, and finishing in goods. They are available in various types. For instance, Carbon Steel Blind Flanges are used to terminate the pipe. High-grade raw material is used to manufacture these flanges. They have a carbon content in the range of 0.25% to 0.60%. Due to the high volume of carbon and manganese, the fabrication of the product is excellent and ductility is also good.
There is another type of flange that is known as killed Carbon Steel Forged Flanges. They are destroyed in the melting process. Due to the addition of manganese, silicon, and aluminum during the production of steel, deoxidation takes place. Carbon Steel Plate Flanges are welded onto the pipe which helps in bolting and connecting one pipe to the other. It displays good ductility, and toughness. These Carbon Steel Pipe Flanges also work well in low temperatures. They are used in fuel and water pipelines. The cost of these flanges ranges between Rs 398 to Rs 689.
To strengthen and harden the steel and cast iron alloy Carbon Steel Slip On Flanges are passed through a process known as quenching. They are used in various construction, engineering, and petrochemical industries. The outer diameter of the slip-on flange is also welded. Carbon Steel Weld Neck Flanges have a neck extension at the end. This type of flange is directly buttwelded to the pipe to provide a natural connection. Carbon Steel Flanges manufacturers in India recommend the use of these flanges when the conditions are critical and severe.
Carbon steel flanges are produced from pressure vessel plates or forged steel rings. Mill plate produced to the A516 Gr60 or A516 Gr70 standards is virtually free of voids, non-metallic inclusions, and other defects. Steel Flanges are widely accepted in pressure vessel and pipeline applications. Carbon steel Shell flange, Carbon steel end cover flange Customized flange.
Here is the detailed feature and performance table for carbon steel flanges in English, including data ranges for specifications, common standards, types, flange faces and connection methods, and the manufacturing process:
Feature/Performance | Description |
---|---|
Strength | Carbon steel flanges are known for their high strength, capable of withstanding significant pressure and mechanical stress. |
Cost-Effectiveness | These flanges are cost-effective, providing excellent mechanical properties at a reasonable price point. |
Wide Range of Applications | Carbon steel flanges find use in diverse applications, including oil and gas, petrochemicals, construction, and more. |
Common Material Grades | Carbon steel flanges have various material grades, but two common grades are: |
– ASTM A105 | Widely used carbon steel grade suitable for general-purpose applications. |
– ASTM A350 LF2 | Low-temperature carbon steel grade ideal for cryogenic and sub-zero environments. |
Specification Sizes | Carbon steel flange specifications and sizes vary depending on standards (such as ANSI B16.5, ASME B16.47, etc.) and specific application requirements. Here are typical data ranges: |
– Flange Diameter | From 1/2″ (15mm) to 48″ (1200mm) |
– Flange Thickness | From 1/4″ (6mm) to 6″ (150mm) |
– Number and Spacing of Bolt Holes | Varies with specifications and pressure ratings, typically 4, 8, 12, or more, with different spacing. |
Common Standards | Carbon steel flanges typically conform to one of the following standards: |
– ANSI B16.5 | Flange standard established by the American National Standards Institute, widely used in various engineering projects. |
– ASME B16.47 | Flange standard developed by the American Society of Mechanical Engineers for large and high-pressure flanges. |
Types | Carbon steel flanges come in various types, including: |
– Slip-On Flange | Commonly used in pipeline systems, allowing the flange to rotate, suitable for various angles of welding. |
– Blind Flange | Used to seal one end of a pipe, typically used during maintenance or inspection periods. |
Flange Faces and Connection Methods | Flanges typically have two types of flange faces and connection methods: |
– Flat Face | Low-temperature carbon steel grade is ideal for cryogenic and sub-zero environments. |
– Raised Face | The Flange face is slightly raised, often used in high-pressure or high-temperature applications, and sealed with gaskets. |
Manufacturing Process | The general manufacturing process for carbon steel flanges includes: |
– Cutting | Cutting the required flange blanks from raw materials. |
– Forging | Forging the blanks into the desired shape, increasing density and mechanical properties. |
– Machining | Processing the forged flanges, including hole drilling, thread machining, and surface finishing. |
– Inspection | Conducting various quality inspections to ensure compliance with standards and specifications. |
– Packaging and Delivery | Packaging the final flange products and delivering them to customers or project sites. |
This comprehensive table provides detailed information about the features, performance, common material grades, specification sizes, standards, types, flange faces and connection methods, and the manufacturing process of carbon steel flanges. It will help you gain a comprehensive understanding of carbon steel flanges’ characteristics, enabling you to make informed decisions regarding material and specification choices to meet specific engineering requirements. Please note that selecting the right specifications, sizes, and flange types is critical to ensuring the effectiveness and reliability of flanges in a system.
HOW TO PREVENT CARBON STEEL FLANGE FROM RUSTING?
Carbon steel can get rust, but you can prevent it using the following solutions:
1. Oil varnishing: It helps to lubricate the carbon steel. Oil forms a protective barrier against rust and allows them to move with friction.
2. Anti-rust painting: Painting a carbon steel flange helps to cover metal components in a protective layer. It helps to prevent moisture from reaching the metal and therefore prevents rust and general corrosion.
3. Electric zinc-coated (Yellow or white zinc): Galvanising or electric zinc-coating is one method to prevent rust. It is easy to stop the reach of water and oxygen underneath the metal by coating it in a thin layer of zinc.
