(1) It is not necessary to use the blank as a raw material, which can save the cost of the pipe making equipment and the mold, and can obtain a carbon steel elbow of any large diameter and relatively thin wall thickness.
(2) The blank is a flat plate or a developable curved surface, so the material is simple to cut, the precision is easy to ensure, and the assembly and welding are convenient.
(3) Due to the above two reasons, the manufacturing cycle can be shortened and the production cost is greatly reduced. It is especially suitable for processing large carbon steel elbows on site because it does not require any special equipment.
(4) Carbon steel elbows are suitable for pipeline systems in the petroleum, natural gas, chemical, hydropower, construction and boiler industries.
