(1) It does not need pipe blank as raw material, which can save the cost of pipe making equipment and mold, and can obtain carbon steel elbow with any large diameter and relatively thin wall thickness.
(2) The blanks are flat plates or developable curved surfaces, so the blanking is simple, the accuracy is easy to ensure, and the assembly and welding are convenient.
(3) For the above two reasons, the manufacturing cycle can be shortened and the production cost can be greatly reduced. Because no special equipment is required, it is especially suitable for processing large carbon steel elbows on site.
(4) Carbon steel elbow is suitable for pipeline series in petroleum, natural gas, chemical, hydropower, construction and boiler industries.
