High pressure Swivel Joints is a ball bearing mounted metal pipe fittings, oilfield workover connection line, red sand commonly used tools, which can regulate the orientation changing, quick connection, reasonable structure, small size, light weight, sealed good performance, safe, reliable, easy to operate features, and its specifications are 2 "to 4", rated working pressure of 42 ~ 105MPa (6000psi ~ 15000psi), can provide various types of activities bent at room temperature, low sulfur gases and conditions of use head and kits. Swivel Joints have long radius elbows and short radius of two types, long bend radius activities have a smooth path, the liquid can be minimized through the resistance of the fluid on the corner of the wall thickness of resistance to erosion corrosion better than short radius, but sometimes due to the lower limit or pressure field installation space is also used short radius.
