Structural Features
● Bending radius: the bending radius of the long radius (LR) elbow is usually 1.5 times the nominal diameter of the pipe, and this design helps to reduce the resistance of fluid flow in the elbow and reduce the scouring and wear of the fluid on the pipe wall.
● End connection: the ends of the elbow are usually butt-welded connection, that is, by welding with the end of the pipe to realize the connection, this connection has the advantages of solid connection and good sealing.
● Size specifications: Butt-welding 180° long radius return elbow has various size specifications, including different nominal diameters, wall thickness, etc., to meet the needs of different piping systems.
Application Scenario
● Petroleum and Gas Industry: Used in pipeline system for transporting oil, gas and so on.
● Chemical Industry: It is used to connect various devices and tubes in the course of chemical production, to ensure that the fluid flows along a predetermined path.
● Electricity Industry: It is used to change the flow direction of cooling water in a power station cooling system.
● Other: such as shipbuilding, paper-making, food-processing, and so on, also widely used in 180 ° radius butt welding.
