Carbon Steel Flange Supplier in MOZAMBIQUE 

Carbon steel flanges are essential for piping systems to connect pipes, valves, pumps, and other equipment. They are made from carbon steel, a steel alloy primarily composed of iron and carbon, with different elements added to enhance properties like strength, hardness, and durability. Carbon steel flanges are known for their strength, resistance to corrosion, and affordability, making them widely used in various industrial applications.

Several carbon steel flanges are designed for specific purposes and applications. Some of the most common types include:

1. Slip-on Flanges in MOZAMBIQUE (SO): These flanges have a slightly larger bore diameter than the outside diameter of the pipe. They are slipped over the pipe and then welded at the inner and outer edges, providing a strong and secure connection.

2. Weld Neck Flanges in MOZAMBIQUE (WN): Weld neck flanges feature a long, tapered hub that provides an ideal pipe connection. They are welded to the pipe and the adjoining pipe, offering excellent strength and stability, particularly in high-pressure and high-temperature applications.

3. Blind Flanges in MOZAMBIQUE (BL): Blind flanges seal the end of a pipe or vessel. They are typically used in applications where future expansion might be needed or temporarily block off a pipeline.

4. Socket Weld Flanges in MOZAMBIQUE (SW): Socket weld flanges are designed with smaller-diameter pipes. They are welded directly onto the pipe, creating a smooth bore and a tight seal.

5. Threaded Flanges in MOZAMBIQUE: These flanges have internal threads that allow them to be screwed onto the pipe. They are commonly used in low-pressure applications and where welding is not feasible.

6. Lap Joint Flanges in MOZAMBIQUE (LJ): Lap joint flanges are used with stub ends. They allow for easy alignment of bolt holes and are ideal for non-standard connections or systems requiring frequent dismantling.

7. Orifice Flanges in MOZAMBIQUE: Orifice flanges are specifically designed for flow measurement or restriction applications. They feature a small orifice opening that can be used with an orifice plate to measure flow rates.

8. Ring-Type Joint (RTJ) Flanges in MOZAMBIQUE: RTJ flanges use a ring joint gasket to create a tight seal in high-pressure and high-temperature applications. They are commonly used in the oil and gas industries.

These are just a few examples of the many carbon steel flanges available, each with unique features and advantages suited to different piping requirements.
