Abstract
Experimental studies of the tensile and compression strength as well as the strength at three-point bending of heat exchange tubes with various types of surface intensifiers, were made. The effect of intensifier geometry on sample strength is shown. The ranges of geometric parameters of intensifiers, which provide high-performance characteristics of heat exchange tubes, and possibilities to improve the maintenance reliability, are given.
