What problems should be paid attention to in the design of steel skeleton PE composite pipes?


Because of the particularity of the material of the steel skeleton PE composite pipe, it needs to synthesize all kinds of factors and combine with the whole structure of the pipe to design the pipe. Because of the unstable factors of the material itself, how to choose the steel skeleton PE composite pipe should be considered in the design. Several questions:


(1) Because of the connection method and pre-processing characteristics of this kind of pipe, the technical disorder belongs to high-precision prefabricated type. Any change of scale and direction will result in the extension of the construction period. Therefore, it is necessary for the planner to make the construction drawings accurately, especially for similar reconstruction projects.

(2) As the steel skeleton PE composite pipe is a new type of environmental protection pipe, it has not a comprehensive and specific specification in many data and articles of association, so it needs to be integrated into the design according to the similar specifications of the relevant pipe as a reference factor.




(3) From the point of view of the operator's reaction, long-distance laying should consider the installation of pipeline compensation equipment, but so far there is no more appropriate compensation method, generally can choose flange connection, but the connection point to think as far as possible in the valve well and other places, to prevent burial and corrosion more troublesome.




(4) Because of the limited variety of pipe fittings, the treatment of irregular turning angles should be considered in the layout. First, rigid fittings should be selected, and second, longitudinal expansion bending and elbow turning to any viewpoint should be used in the pipeline. These two methods have bad gas effects on the water conservancy conditions of the pipeline, so they are needed in operation. Extra care.
