Pipe fittings mainly include several types: welded, compression, crimp, and flared.
Welded pipe fittings: These connect pipes together by welding, offering high connection strength and sealing performance. They are typically used for transmitting high-pressure, high-temperature, and corrosive media.
Compression fittings: These connect pipes using compression fittings. Installation is simple, and they are suitable for medium and low-pressure hydraulic systems. However, it should be noted that compression fittings may loosen or leak during use due to vibration or temperature changes.
Crimp fittings: Primarily used for hose connections, these are characterized by ease of installation and disassembly. They secure the hose to the fitting by crimping, providing good sealing and reliability. This type of fitting is suitable for applications requiring frequent disassembly and installation.
Flanged pipe fittings: These are made by flaring the pipe end and fitting it onto the fitting, then securing it with threads. Flared fittings can withstand greater pressure and impact, and are commonly used in high-pressure and high-vibration applications.
