With the development of industry such as electric power transmission,communications,capital con-struction piling,prefabricated construction,wind power,oil transportation,and gas pipelines,the requirements for the variety and specifications of forming machines are constantly increasing.Heavy type pipeline fabrica-tion forming machines are the core equipment for producing various types of steel pipes.This paper compares the status and technical level of domestic and foreign pipe forming machines before 2010,as well as two different pipe forming processes and their technology economy.The development status and technical level of domestic and foreign pipe forming machines after 2020 were discussed,and the development trends in the main structure,hydraulic system,control system and other aspects of heavy type pipeline forming machines in the future were proposed.
