Different methods exist for joining steel pipes, depending on specific applications and requirements. Some commonly employed techniques include the following:
1. Welding: Among the most frequently used methods to join steel pipes, welding involves heating the pipe ends and applying pressure to fuse them. Various techniques can be employed, such as arc welding, MIG welding, TIG welding, and even laser welding.
2. Threaded connections: This method involves threading the ends of steel pipes to create male and female connections. These threaded ends are then screwed together using pipe threads. Threaded connections are typically utilized for smaller diameter pipes and in low-pressure applications.
3. Flanged connections: Flanges are employed to join steel pipes in situations that necessitate easy assembly and disassembly or frequent maintenance. Flanges are flat, circular discs with bolt holes that allow for the bolting of pipes together. They offer a robust and leak-proof connection.
4. Compression fittings: Compression fittings enable the joining of steel pipes without the need for welding or threading. They consist of a compression nut, compression ring, and compression sleeve. The nut is tightened onto the sleeve, compressing it against the pipe and creating a secure connection.
5. Grooved couplings: Mechanical connections are created with grooved couplings, which are utilized to join steel pipes. The pipe ends are grooved, and a gasket is inserted between the grooves. The couplings are then tightened, compressing the gasket and forming a tight seal.
6. Soldering or brazing: These methods involve the use of filler metal with a lower melting point than the steel pipes. The filler metal is heated and melted, allowing it to flow between the pipe joints and create a bond. Soldering is generally suited for smaller diameter pipes and low-pressure applications.
Each joining method has its own advantages and limitations. The appropriate method for joining steel pipes depends on factors such as pipe diameter, application, working pressure, and required joint durability. It is crucial to consider these factors and consult industry standards and guidelines when selecting the suitable joining method for steel pipes.

3. Flanged connections: Flanges are used to join steel pipes in applications that require easy assembly and disassembly or when frequent maintenance is needed. Flanges are flat, circular discs with bolt holes that allow the pipes to be bolted together. The flanges provide a strong and leak-proof connection.
4. Compression fittings: Compression fittings are used to join steel pipes without the need for welding or threading. They consist of a compression nut, a compression ring, and a compression sleeve. The nut is tightened onto the sleeve, compressing it against the pipe, creating a secure connection.
5. Grooved couplings: Grooved couplings are used to join steel pipes by creating a mechanical connection. The pipe ends are grooved, and a gasket is placed between the grooves. The couplings are then tightened, compressing the gasket and creating a tight seal.
6. Soldering or brazing: These methods involve using a filler metal that has a lower melting point than the steel pipes. The filler metal is heated and melted, allowing it to flow between the pipe joints, creating a bond. Soldering is typically used for smaller diameter pipes and low-pressure applications.
