Study of internal corrosion on the turning angles in steel pipes

Abstract

Corrosive damages can lead to accidents on pipelines in various industries. Therefore, the main objective of the work is to study the peculiarities of propagation of internal corrosion on turning angles in steel pipes. The paper substantiates the primary importance of the propagation of corrosion on turning angles in steel pipes. It has been identified that in curvilinear areas, the rate of corrosion propagation depends on the rate of fluid flow, on the number of ions, and also on the effect of centrifugal force. The authors studied the average rate of corrosion propagation on the turns in steel pipes. Thus, the results obtained showed that the location of steel pipes affect the rate of corrosion propagation inside the pipes.

Polymer concrete production technology with improved characteristics based on furfural for use in hydraulic engineering construction

“…The rods were kept 28 and 60 days after the samples manufacture. The test data showed that the adhesion of the reinforcement to polymer concrete is 108 kg/cm 2 [25].…”

“…The corrosion effect of polymer concrete on steel reinforcement was studied by the following method [25]. Cube-samples were made from composition # 3 measuring 10×10×10 cm: aggregate -ground andesite and gravel with a grain size of 20-40 mm in a ratio of 1:1.5 by weight -1w.p.…”

“…No traces of corrosion were found on the surface of the rods. Consequently, the environment of polymer concrete based on FD resin does not have a corrosive effect on steel reinforcement [25].…”
