The oil and gas industry is one of the most challenging industries due to adverse conditions and demands involved. A few engineered components such as oil seals are required to perform in these adverse conditions, where they may be exposed to various extreme conditions. Although most of these seals are precision designed for a long-term performance, they may fail due to several reasons. This post gives a brief insight into the challenges that the seals are exposed to, and explores various reasons behind their failure.
An Overview on the Challenges Endured by Gas and Oil Seals
Mechanical seals are always designed in adherence to the conditions of a particular application where they may be used. Oil and gas seals are designed to resist the following:
Analyzing the Top 3 Reasons for Failure of Oil Seals and Corrective Actions
Like any regular mechanical seal, oil seals fail due to several reasons or one of these reasons. Here, the failure reasons are also followed by their solutions.
Solution: Selection of the right sealing material is important for ensuring the compatibility of the seal with chemicals. This chemical incompatibility leads to chemical attacks, which accelerate at high temperatures or pressures. So, check the compatibility of the elastomer seal material before choosing it for your application.
Solution: Many industry experts suggest using backup devices to avoid the formation of clearance gaps between the mating edges. The selection of a properly sized oil seal is also important to avoid extrusion and nibbling.
Solution: Use the materials that are rated to the temperature of application. Also, ensure that the elastomer used is free from volatile ingredients such as waxes, plasticizers, and so on. Both these will help you avoid the chances of outgassing.
The above mentioned are only the top three causes of oil seal failure; however, there can be several other reasons for the same. In addition to these solutions, it is important that you source these seals from some trusted manufacturer such as SSP Seals. The company provides customized oil seals in different specifications to its clients in the oil and gas industry.
