Description

1. Flared pipe joint: These hydraulic fittings are suitable for connecting copper pipes, thin – walled steel pipes, nylon pipes, and plastic pipes. They feature a simple structure and are well – suited for medium and low – pressure pipeline systems.
2. Welded pipe joint: They are connected by welding the pipe to the inner core of the fitting. They offer good sealing, a simple structure, and strong pressure resistance. However, a large amount of welding is required during installation, making installation and disassembly inconvenient.
3. Card sleeve pipe joint: These hydraulic fittings use an elastic card sleeve to clamp the oil pipe for sealing. With a simple structure and convenient installation, they are suitable for connecting high – pressure cold – drawn seamless steel pipes.
4. Crimp pipe joint: These fittings are suitable for hose connection and are composed of a fitting jacket and a fitting core.
5. Removable pipe joint: These hydraulic fittings are convenient for frequent removal of the hose and are suitable for connecting high – pressure small – diameter hoses.
6. Quick-change pipe joint: These hydraulic fittings have a complex structure and are suitable for pipeline systems with oil and gas as the medium.
