Abstract
Pipes made from polymeric, corrosion-resistant materials offer variety of advantage over traditional steel pipes. In recent years, these pipes have become increasingly common in the construction of field pipelines of different purpose. Given that these pipelines represent complex and costly infrastructure systems, the problem of ensuring their structural reliability – both during the use of advanced technologies and throughout their further operation – has a critical national-economic importance. When transporting hydrocarbons through field pipelines made of multilayer polypropylene reinforced pipes, it is essential to account for stresses induced by pipe bending and temperature drops. To properly select a bending radius that meets the required strength properties of multilayer reinforced polypropylene pipes, the authors addressed the problem of determining allowable bending radii. Additionally, the authors an algorithm developed an algorithm to assess the stress-strain state of curved sections of pipelines made from multilayer reinforced polypropylene. This work is of particular relevance. This is due to the fact that implementing the algorithm into object-oriented visual programming systems – during accumulation of sufficient databases and pipeline facilities passportization – will be possible to create software with advanced graphical interfaces using procedural programming languages.
