Research on application and experimental platform of ductile iron heating pipes

In order to test the performance of ductile iron pipes under heating operation parameter conditions, a test platform is built using DN1200 ductile iron heating pipes in the project of connecting Binhe East Road and Industrial Road in Linfen City as an example, and their heat transfer, stress and strain, and pipe leakage performance are tested. The research results show that the ductile iron heating pipes have reliable stress performance, good thermal insulation performance, and safe operation, providing a practical basis for the application of ductile iron thermal pipes.
