Carbon Steel Flange

Flanges made of carbon steel are called carbon steel flanges. The CS flange itself has a compact structure, reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are always in a closed state and are not easily eroded by the medium. It is easy to operate and maintain. It is suitable for general working media such as water, solvents, acids, and natural gas. The surface of the flange cs itself is flat and smooth, without burrs, scratches, warping, unevenness, etc. The carbon flanges have high tensile, compressive, torsional, and shear strength.

Carbon steel flange appearance

1. Carbon steel flanges have a matte grayish appearance, characteristic of the steel’s composition;
2. CSflanges are generally circular in shape, with a central bore (hole) through which the pipe passes;
3. There are bolt holes around the perimeter of the flangesCS, evenly spaced, through which bolts are inserted to secure the flange to the mating component. These holes are usually drilled or machined with precision to ensure alignment during installation.

Types of carbon flange

1. Weld neck flanges feature a long tapered hub that provides reinforcement to the flange and allows for smooth transition to the pipe. They are welded to the pipe, offering excellent strength and reliability, particularly in high-pressure and high-temperature applications;

2. Slip-on flanges have a slightly larger bore diameter than the outer diameter of the pipe. They are slipped over the pipe and then welded both inside and outside to provide strength and prevent leakage. Slip-on flanges are easier to align and install compared to weld neck flanges and are commonly used in low-pressure applications;

3. Blind flanges are solid discs with no bore and are used to close the end of a piping system or vessel. They are typically used for pressure testing or to block off sections of a pipeline temporarily. Blind flanges are often installed with gaskets between mating flanges to ensure a tight seal;

4. Socket weld flanges have a socket or bore that is used to insert the pipe into the flange. The pipe is then fillet welded from the outside to provide strength and prevent leakage. Socket weld flanges are ideal for smaller-sized pipes and high-pressure applications;

5. Threaded flanges have internal threads that match the external threads of the pipe. They are screwed onto the pipe and then tightened with a wrench. Threaded flanges are commonly used in low-pressure, non-critical applications where easy assembly and disassembly are required;

6. Lap joint flanges consist of two parts – a stub end and a loose backing flange. The stub end is welded to the pipe, while the backing flange slides over the pipe and is free to rotate. Lap joint flanges are used in systems that require frequent dismantling or where alignment of the bolt holes is necessary;

7. Orifice flanges are specifically designed to accommodate orifice plates or flow meters in a pipeline. They feature a small bore that matches the bore size of the orifice plate and are often used in measuring and regulating fluid flow.

Carbon steel pipe flange applications

1. Carbon steel flanged fittingsare extensively used in upstream, midstream, and downstream operations within the oil and gas industry. They are employed in pipelines, refineries, offshore platforms, and petrochemical plants for connecting piping systems, valves, pumps, and other equipment;
2. In chemical processing plants, carbon steel fittings and flangesare used to connect pipes and equipment that handle corrosive chemicals and substances. They are chosen for their resistance to chemical corrosion and high temperatures, making them suitable for a wide range of chemical applications;
3. Carbon steel flanges are commonly used in water treatment plants, sewage treatment facilities, and desalination plants for conveying and controlling the flow of water and wastewater. They are employed in piping systems for pumps, valves, filters, and other equipment;
4. CSflanges play a crucial role in power generation facilities such as thermal power plants, nuclear power plants, and renewable energy installations. They are used in steam, water, and gas distribution systems, as well as in boilers, turbines, condensers, and heat exchangers;
5. FlangesCS are used in mining operations and mineral processing plants for transporting ores, minerals, and slurries. They are employed in pipelines, conveyors, and equipment such as crushers, mills, and separators;
6. In shipbuilding and maritime applications, carbon flangesare used in piping systems for ship propulsion, ballast systems, cargo handling, and offshore structures. They are chosen for their strength, corrosion resistance, and reliability in marine environments.

Advantages of carbon steel pipe flange

1. Carbon steel flanged fittingshas good strength and toughness, and can maintain a certain strength in low temperature environments;
2. Carbon steel fittings and flangeshave better corrosion resistance;
3. Compared with flange products made of other materials, carbon steel flanges have lower costs and are widely used in various fields.

Carbon steel flanges manufacturers

1. Advanced science and technology

All of our carbon flanges are forged. The forging process includes the following processes, that is, selecting high-quality steel billets, heating, shaping, and cooling after forging. The advantage of forged flanges is that the internal structure is uniform, the casting has no pores, and there are no harmful defects.

2. Strict inspection

We have quality control during the manufacturing process. All carbon steel pipe flanges undergo strict process inspection at every stage of the production process, from raw material handling to finished product shipping. They are visually inspected for compliance with our specifications and inspected and tested in accordance with applicable ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, you can also invite an officially certified testing agent to witness the inspection procedure.

3. Customized on demand

Our carbon steel flanged fittings can be customized on demand including construction, electric power, petroleum, chemical industry, pipelines, etc.

4. Pack and deliveron time

Our factory will complete production as soon as possible and deliver carbon steel fittings and flanges on time according to your order, ensuring that your receiving is not delayed.
