The advantages of the production process of steel pipe elbow are mainly in the following aspects: without tube blank as raw material, can save the cost of pipe making equipment and mold, and can get any large diameter and relatively thin wall thickness of carbon steel head. Blank for the flat or surface can be developed, thus cutting a simple, easy to ensure accuracy, easy assembly and welding. Due to the above two reasons, the manufacturing cycle can be shortened and the production cost can be greatly reduced. Because it does not require any special equipment, especially suitable for on-site processing of large carbon steel elbow. Welded steel elbow pipe for oil, natural gas, chemicals, utilities, construction and boiler industries such as pipeline series.
