21. New Engineering Solutions in the Production of Laminated Composite Pipes for the Oil Industry

The oil industry of Russia currently needs innovative development projects intended for a radical improvement of the performance of material resources and a decrease of their consumption. One of the most promising trends in corrosion protection is the production and use of pipes made of laminated composite materials. There are several principal ways of producing them by metal forming processes. World practice shows that lining technology is reasonable for oil well tubing. Lining consists of simultaneous expansion of pipes made of dissimilar materials, which possess different properties. A pipe of the kind manages to combine high corrosion resistance and mechanical strength, and this makes its service life more than four times higher than that of pipes made by conventional methods. However, previous foreign experience of manufacturing and using these pipes prompts the necessity of improving some pipe-making processes. This paper discusses new engineering solutions in the production of lined pipes, as well as in situ testing results.
