Pump pipe as a kind of concrete pump and supporting the use of new type construction machinery, as a manipulator, able to quickly and accurately reach to the construction of the concrete operation of either for continuous casting, casting parts and give full play to the advantages of the two technologies, adopt welding and flange connection, you need to equipped with complex power cable, cutting machine, welding machine and oxygen and acetylene cylinders, etc., this brings to the construction organization complexity, and also there is the danger of leakage and fire hazard. A pipe connection only a few minutes, the maximum simplifies the technical difficulty of site operation, save time, thus the engineering quality is stable, improve the working efficiency. This is also the overall direction of the development of the petrochemical pump installation technology.
