Abstract
The paper gives the results of testing 720 x 10 and 530 x 8 mm pipes with composite-polymer bands in sections with defects simulating local corrosion damage. Joint work of the band and pipe at static and cyclic loading caused by inner pressure is shown. Effectiveness of reinforcement of defective pipeline sections by composite-polymer bands is established and features of fracture of a banded pipe are noted.
Keywords: pipeline, defective sections, strength restoration, composite polymer band, inner pressure, testing, stresses, deformation
