THE STRAIN GAGE METHOD FOR DETERMINATION OF

INPUT WORKING LIFE PARAMETERS OF PIPES IN COMPRESSOR STATIONS

INTRODUCTION

- -

For determination of safety operation of compressor stations and assessment of their residual working life is

necessary to know the levels of residual stresses, operational loading as well as functionality of real support

Key words:
