... submarine pipeline gas field composite pipe lined steel pipe base alloy 625 specification cra inspection strength liner pipe lined pipe ABSTRACT CRA (Corrosion-Resistant Alloy) composite pipe for submarine pipeline has both corrosion resistance and high strength, which can effectively...

... material behavior (UMAT) program to elucidate the essential relationship between composite pipe and attenuation of mechanical properties of the element. For numerical assessment of tensile fatigue failure, the stress and failure element were identified, and stiffness attenuation due to tensile load on FRTP...

... Abstract Through force analysis on pipe body during ocean laying, this paper first puts forward the possible failure modes (e.g. wall thickness reduction exceeds the standard, ellipticity exceeds the standard, liner tube wrinkles, etc.) of mechanical bi-metal composite pipe during the process...

... Fibre reinforced composites have been attractive for certain industrial applications because of improved stiffness and corrosion resistance. In this study three composites pipes of stacking sequence [0 2 /45 2 /90 2 /-45 2 ] s , [45 2 /0 2 /90 2 /-45 2 ] s and [90 2 /45 2 /0 2 /-45 2 ] s were...

... by a defect is measured through the use of a laser vibrometer. The technique was tested on graphite/epoxy and glass/epoxy composite pipes. It is shown that small defects in the pipe wall may be detected at a distances on the order of one meter from the transducer. INTRODUCTION In order for composite...
