With the development and progress of pipeline technology for pipe bending machine, the transportation of crude oil and refined oil products has been changed from the transportation of automobile and train to the transportation of long-distance oil and gas pipelines. Analysis on the successful application of small vertical pipe bender: in the current construction, with the progress of technology and the expansion of the project, for some good details are required to deal with very well, so that it is applied to the small pipe bender.

Most of the former pipe bender is imported, and the imported pipe bender has many disadvantages such as high cost and insufficient supply of spare parts, which seriously restrict the production capacity of pipeline construction. In the process of laying oil pipeline, pipe bender often needs to bend the pipe because of the dead mouth or around obstacles. Therefore, in the field construction, the pipe bending machine is used to simmer the pipe. The small vertical pipe bender mainly uses hydraulic technology, hydraulic equipment has a good power to weight ratio, the use of hydraulic system to make its structure simple, etc., in line with the characteristics of hard field construction conditions, to meet the needs of field construction.
