Objectives

The application of plastic coated pipeline in rural water supply projects is more and more extensive, but the small diameter pipeline is easy to destroy the internal anti-corrosion layer after welding, in order to solve the above problems, the goal of this topic is to form a set of economic and reasonable and can ensure the quality of pipeline anti-corrosion solution - anti-corrosion robot application technology.

Conclusions

1. The connection methods of plastic coated pipes are mainly wire connection, flange connection, bimetal welding, etc., of which wire connection is only suitable for small-caliber low-pressure pipes, because flange connection and bimetal welding need to match flanges and embedded metals, so each interface, the construction cost of the internal anti-corrosion robot is about 100 yuan lower than the above process, with good economic advantages
2. The internal anti-corrosion robot is used for welding machine, and the pipeline can make turns with the change of terrain, and can realize welding and internal anti-corrosion construction at the same time, and the construction is convenient
3. Therefore, the anticorrosive technology of internal anticorrosive robot pipeline has a broad application prospect in rural water supply projects
