Welded pipe joints and ferrule fittings characteristics

Welded pipe joints
Use over and pipe welding. Between the connector body and takes over the O-ring seal. Simple structure, easy to manufacture, sealing, pipe size for less precision. Requires high quality welding, assembly and disassembly inconvenience. Working pressure up to 31.5MPa, operating temperature -25 ~ 80 ℃, as the medium for the oil pipeline system.
Card sets of pipe joints
Stuck pipe deformation using the card sets and sealed, advanced structure, good performance, light weight, metric hydraulic fittings small size, easy to use, widely used in hydraulic systems. Working pressure up to 31.5MPa, required pipe size, high precision, cold drawn steel pipe required. Card sets are also high precision. For oil, gas and general corrosive media pipeline system
