28.3. Replace the underlined words with a suitable variant from the text.
Example: 6. working – operating
1. Buried steel pipes suffer from outer corrosion.
2. DC flows between the pipe and an anode ground bed through the soil.
3. Transformer stations are controlled by output voltage data.
4. Corrosion control measures include water elimination and drying.
5. A sacrificial anode method depends on the installation of anodes on or near the pipeline.
6. The severity of corrosion depends on the working temperature.
28.4. Match the terms with Russian equivalents.
Example: 15. deterioration – L. ухудшения характеристик
1. weakening A. подаваемый ток
2. rust B. коррозионный элемент
3. discoloration C. выходное напряжение
4. impressed current D. интенсивность
5. direct current E. (удельная) проводимость
6. corrosion cell F. ослабление
7. output voltage G. обезвоживание
8. severity H. постоянный ток

10. conductivity J. ржавчина
11. operating pressure K. толщина стенки
12. yield strength L. ухудшения характеристик
13. allowance M. рабочее давление
14. wall thickness N. предел текучести

In this system, 4. __________ __________ is supplied to the pipeline. The current is adjusted to generate higher 5. ___________ _________. A 6. _________ __________ 7. relies upon the installation of 8._______ on or near the pipeline. The pipeline becomes the cathode of the system and the anodes 9.________ corrosion of the pipeline. When water is present on the transported fluid, corrosion of the internal pipe surfaces can also occur.
