REGULARITIES OF CREATION OF LAYERED METAL CORROSION-RESISTANT MATERIALS WITH INTERNAL PROTECTOR

In this article regularities of the creation of laminated metal corrosion-resistant materials with an internal protector obtained by explosion welding are considered. For the first time, a laminated material is considered as a technical system. A systematic approach was used to construct the configuration of layered materials. The functions of individual elements are identified, the nature of the connections is established, and the complexity of the system is assessed. Corrosion tests were carried out, indicators of corrosion resistance were calculated by varying the number of protected and protective layers in comparison with monometallic material. An assessment of the economic efficiency of using laminated metal corrosion-resistant materials with an internal protector is carried out in comparison with monometallic and bimetallic materials.

PRODUCTION BY EXPLOSION WELDING OF SEAMLESS PIPES MADE OF LAYERED METAL MATERIALS INCREASED CORROSION RESISTANCE

The paper presents schemes for producing seamless pipes made of multilayer metal material with an internal protector using explosion welding technology. The developed scheme of explosion welding to the original liners for later they rolled into a seamless tube. The features of creating permanent joints from these materials using arc welding methods are indicated.
