Device for determining adhered forms of SRB at the pipeline corrosion control unit

摘要

The utility model relates to the field of the oil industry, in particular, it provides trouble-free operation of the pipeline transport system, control of the microbiological activity of sulfate-reducing bacteria (SRB) and corrosion processes in the process fluid flow. The technical results are to improve the quality of monitoring the corrosion process, expand the functionality and increase the reliability of the determination of corrosion processes and microbiological activity of adhered forms of SRB in the process fluid flow in an operating pipeline, which makes it possible to reduce pipeline wear, eliminate an emergency, and increase the overhaul period of the equipment of the transportation system during using a simple design of the witness sample for complex monitoring of the corrosive activity of the environment. The device for determining the adhered forms of SRB at the pipeline corrosion control unit includes a rod made with an external thread at both ends, a lead-through bushing 4 with an outer diameter of 30.5 mm is installed in series on the rod, a landing bushing 5 with a diameter of 20 mm, on which three cylindrical specimens are mounted - witness 1 of the corrosion rate with a diameter of 24.5 mm, then an insulating sleeve 6 with a diameter of 30.5 mm is installed, a bushing, on which three cylindrical witness specimens 7 with a diameter of 24.5 mm are mounted, on the outer surface of each around the circumference evenly at an angle of 120 ° six recesses 8 with a diameter of 6 mm are made, the clamping nut 3 is made of fluoroplastic with an internal thread. Insulating fluoroplastic bushings 2 are placed between the witness specimens. The height of the witness specimens, the bushing and the length of the rod depend on the inner diameter of the investigated pipeline. 1 ill.
