Seamless carbon steel pipe connection method

Seamless carbon steel pipes can be connected using various methods, each suited for different applications. These methods are generally easy to install, solid, and reliable. Here are some common connection methods.

Compression:

Process: The pipe is inserted into the fitting’s mouth and tightened using a nut.

Mechanism: The tightening action compresses a sealing ring around the pipe, creating a leak-proof seal.

Applications: Commonly used in plumbing systems where quick and reliable connections are needed.

Welding:

Process: The pipe ends are prepared with a beveled groove and joined using manual or automatic welding.

Mechanism: Welding forms a strong, permanent joint by melting and fusing the pipe material.

Applications: Suitable for high-pressure and high-temperature systems where a robust, durable connection is required.

Flange:

Process: Flanges are welded to the pipe ends, and the connection is secured using bolts or clips.

Mechanism: A gasket between the flanges ensures a tight seal when the bolts or clips are tightened.

Applications: Ideal for systems that may need to be disassembled for maintenance, such as in industrial piping.

Clamping:

Process: The pipe is inserted into a fitting and deformed using a special tool to create a hexagonal shape.

Mechanism: This deformation secures the pipe and creates an internal seal.

Applications: Common in HVAC systems and other applications where a quick and secure connection is necessary.

Taper Thread:

Process: External threads are TIG welded to the pipe, and the pipe is then connected using tapered threaded fittings.

Mechanism: The tapering of the threads ensures a tight seal as the fittings are screwed together.

Applications: Used in systems requiring precise and leak-proof connections, such as gas and oil pipelines.
