Selecting the right welded-metal bellows seal Understand the differences to get the most effective product for the application

摘要

Welded-metal bellows seals are a core sealing technology and have gained popularity in recent years as their use expands to a variety of new innovative sealing technologies such as high-temperature, noncontacting, gas-lubricated seals and high-temperature, corrosion-resistant seals. This is especially important in the oil, gas and chemical industries where pumping liquid from one area to another is complicated with great temperature extremes. Unfortunately though, all seals are not the same. Differing features, materials and a host of other factors can impact overall seal effectiveness. Only with an understanding of these differences can plant operators select the most effective product for the application.
