ABSTRACT

 As a result of analyzing the causes of defects in high-pressure valves, it was found that gate and seat failures are dominant. From this point of view, it is important to increase the service life of the parts included in this pair.

The article discusses the implementation of the iron process and the results obtained in order to increase the resource of the gate-seat pair of high-pressure gate valves. It turned out that the coating of the gate's working surface by the iron-iron method allows, along with an increase in corrosion resistance (by 1.5-1.7 times), creates a serious basis for increasing the service life by 75-80%.

Keywords:  iron process, electrolysis method, gate, service life.
