(1) need not tube for raw materials, can save Short di pipes making equipment and mold cost, and can be arbitrarily large diameter and wall thickness relatively thin Elbow push system. This push bend material is special, need not join the tube material, easy to control during processing.
(2) billet pushing elbow is flat or curved surface, so the material is simple, easy to ensure accuracy, convenient assembling and welding, easy to control in the processing of raw materials, simple operation, no complicated process, and welding and assembling more convenient.
(3) because it does not need any special equipment, especially suitable for field processing of large Elbow push system.
