Incorporating a corrosion inhibitor into the packing is thus required, which will influence the anodic or cathodic reactions to produce a minimum corrosion rate. Of the anodic inhibitors evaluated, only those containing an oxidizing anion, such as sodium nitrite, are efficient. Cathodic protection by sacrificial metals such as zinc, contained in the packing, also provides good corrosion control. Better protection with a minimum effect on compression and serviceability characteristics of the packing is provided by homogeneously dispersed sodium nitrite and a zinc-dust interlayer incorporated into the material.

Therefore, from the point of noise attenuation, the diameter of the perforations should be as small as possible. To avoid the nozzles from becoming blocked, nozzles with a minimum diameter of 5mm are frequently used. If the flow velocity in the pipe downstream of the silencer is high, the boundary layer turbulence along the pipe may generate a noise comparable with the attenuated valve noise. 3. Predicting valve noise and silencer performance is a complex matter. Discussions on these subjects, including the design of silencers, may be found in the References 29, 30, 31, 32 and 33.

At this stage, the sealing action has become automatic. 12*13 The pressure gradient at low fluid pressures is more or less uniform, which indicates little influence by the fluid pressure on the sealing action. On the other hand, the readings at high fluid pressure show that 90% of the pressure drop occurs across the packing ring just below the gland. This indicates a dominant influence of the fluid pressure on the sealing action. In the case of high fluid pressures, therefore, the packing ring just below the gland is the most important one, and must be selected for resistance to extrusion and wear and be carefully installed.
