The importance of selection of chemical pipe materials in chemical engineering design

As the basic material of the whole pipeline, the chemical pipe material plays an important role in the whole pipeline design. Its quality directly affects the safety of the pipeline when it is put into use.

When choosing a pipe, it often involves the selection of piping standard, type and size of piping and its components. As a special device for transporting materials, pipelines play an important role in the entire petrochemical plant.

Only by reasonable selection of pipeline material, the pipeline can work normally under various working conditions and the safety and reliability of the operation of chemical plant can be guaranteed.

As the most used component of chemical pipeline, the total amount of pipes used accounts for about two-thirds of the whole pipeline. Therefore, the correct and reasonable selection of pipes has a great impact on the safety and cost of chemical production.

The selection of pipes should follow the comprehensive conditions for the use of pipes and the principle of whether the pipes are reliable and cost-effective.

In the design of chemical pipeline, both of welded steel pipe with seam and seamless steel pipe should be considered. Because the requirements of welding standards for both of pipes are different, the steel pipe should be selected according to the temperature used.

Secondly, the outer wall of the steel pipe has two series of metric and British systems, so the selection should be based on the outer diameter of the steel pipe to adopt different series, to consider whether to use threaded pipe fittings and valve threaded form.
