Abstract

The changes in structure and physical properties of polymeric materials that exploited in a long time with complex mechanical loads used in pipe systems for high-pressure cold water have been studied. A significant reduction in the mechanical properties of polymeric materials has been established. The most typical structural defects that occur in polymer materials during manufacture and in the exploitations, using electron microscopic studies identified.

Highlights

Polymeric materials widely used in modern building and engineering equipment, which lead to constantly increasing demands on their technical, physical and chemical characteristics, increasing the life cycle of such materials
The aim of this work was to study the morphology of the surface and the mechanical properties of polymeric materials used in pipe systems for products for highpressure cold water
The results of research of mechanical characteristics of polyethylene pipes for cold water were slightly different from his other researchers [2, 3]

Summary

Introduction

Polymeric materials widely used in modern building and engineering equipment, which lead to constantly increasing demands on their technical, physical and chemical characteristics, increasing the life cycle of such materials. One of the areas in which polymeric materials use are pipelines and pipeline equipment, which are made from different thermoplastic materials and their compositions, such as polyethylene, polypropylene, polyvinyl chloride, polybutylene, polyamide, different types of filled and thermosetting polymers. Often, for these purposes, as a major matrix material, use highdensity polyethylene (HDPE) brand PE 63, PE 80, PE 100 and PE 100+, which constantly changing and picking up new composite formulations according to the needs of consumers.
