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.

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.
