Use of high pressure elbow: connect two pipes with the same nominal diameter to make the pipe a 90 degree turning head.The raw material of carbon steel seamless elbow is seamless steel tube, the main production process is round tube blank → heating → perforation → three-roller cross rolling, continuous rolling or extrusion → off pipe → sizing (or reducing) → cooling → straightening → hydraulic test (or flaw detection) → marking → warehousing.SCHXX is wall thickness equal, 90e(s) is short radius 90 degree carbon steel elbow;90e(l) represents the elbow with a long radius of 90 degrees;45e(l) represents the elbow with a long radius of 45 degrees;45e(s) represents the bend with a short radius of 45 degrees;180e(s) for short radius 180 degree carbon steel elbow;180e(l) represents the long radius 180 degree elbow;The carbon steel elbow is the metal pipe fitting which changes the direction of the pipe on the carbon steel pipe.The forming process of carbon steel seamless elbow is a process of using special elbow pusher, core die and heating device to make the blank covered on the die move forward under the push of the pusher.Hot push bend deformation characteristics are based on volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter bend diameter, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by hole diameter, wall thickness uniform Angle is obtained.Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production.The forming process can be heated by medium frequency or high frequency induction heating (heating coil can be multi-coil or single-coil), flame heating and reflector heating.
