Original Abstract

Stainless steel corrugated hoses are widely used in many areas of industry. They are used in application such as distribution of drinking and supply water, gas and also various working fluids, for example in cooling systems. During the assembly of AISI 316L corrugated hoses for cooling systems defects form due to deformation of the hoses during assembly. The absolute tightness of such systems is required and any defects of the hoses are therefore undesirable. This study deals with evaluation of most common defects of corrugated hoses via light and scanning electron microscopy and proposes measures to minimize such defects. This study deals with evaluation of most common defects of corrugated hoses via light and scanning electron microscopy and proposes measures to minimize such defects. It was revealed, that defects form due to deformation of the hoses during assembly or, in case of unfavorable microstructure, during the service life. In later case, failure of the hose was caused by higher content of deformationinduced martensite in microstructure as a result of intense cold forming. Component with such microstructure exhibited les favorable mechanical properties and hoses were more prone to the failure.
