Ways to connect pipe fittings to pipes

Piping systems rely on pipes and fittings as fundamental components, each serving distinct functions and possessing unique characteristics. Steel pipes, a common material, are categorized based on cross-sectional shape, material composition, intended use, and production method. Conversely, pipe fittings serve to connect pipelines, facilitating functions like connection, control, direction alteration, diversion, sealing, and support within the system. Various methods are employed to connect pipe fittings and pipes, including:

Threaded Connection:

This method involves screwing together pipes and fittings with internal and external threads, creating a secure joint. It's user-friendly and suitable for low-pressure, small-diameter pipeline systems.

Flange Connection:

Using flanges and flange gaskets, pipes and fittings are joined. Flange connections include flat welding flanges and butt welding flanges, typically utilized in large, high-pressure pipeline systems.

Welding Connection:

Pipes and fittings are welded for a permanent connection. Common welding techniques include butt welding, fillet welding, and socket welding, preferred for high-pressure, high-temperature piping systems.

Clamp Connection:

Clamps secure pipes and fittings together, ideal for smaller diameter systems like water pipes and irrigation setups.

Groove Connection:

Special tools create grooves in pipes, allowing clamps to secure pipes and fittings together using hooks or grooves.

Pressure Connection:

Special pressure tools compress sleeves or seals on pipes and fittings, creating a sealed connection. Methods include ferrule connection, pressure sleeve connection, and link connection, suitable for diverse piping materials.

Tension Connection:

Bolts and nuts are used to fasten pipes and fittings, suitable for large and high-pressure pipelines.

Quick Connection:

Utilizing quick connectors enables rapid assembly and disassembly, ideal for applications requiring frequent changes like liquid or gas transportation systems.
