Ways In Which Piston Seals Ensure Process Safety
In most commercial and industrial applications
, the safety of hydraulic and pneumatic processes depends on the choice of sealing components to a large extent. Piston seals are the sealing element of choice in a number of pneumatic and hydraulic processes and systems. There are several desirable attributes of these seals. These include but are not limited to: tight sealing properties, less consumption of space, light weight, ability to remain unaffected by process media, endurance to high temperature and pressure, low friction and so on.
Of course, there are a number of other industrial requirements for sealing elements and these are catered to by the various manufacturers on the market. In fact, there are some firms that can also offer custom products with respect to size, diameter, thickness, hardness and so on. When seals are made from high quality materials using the best manufacturing techniques, they are likely to last longer and provide excellent results.
Purchasing piston seals
Before you can go ahead and purchase a piston seal, you would need to draw up a list of must-haves for your hydraulic or pneumatic processes. This list will help you make comparisons between the different seals available on the market and make a well-informed decision. The desired shape, size, diameter, material, other geometrical dimensions, resistance, mating surface, etc are just a few points that should feature on the must-have list that you draw up.
There are seals that are especially made for the aerospace or automotive industry, for plastic injection molding applications, for regular or heavy-duty hydraulic and pneumatic cylinders, valves, excavators and hydraulic fracturing machines, and much more.
Advantages of piston seals
In many cases, these seals are considered to be an economical and effective option to the more expensive T-seals and PTFE loaded cap seals. However, there are several advantages over and above these.
Here are a few major advantages:
The installation time and cost is low
With an extended seal life, these components offer reliable performance
There are several applications that are susceptible to high shock loads. In such cases, these seals provide the desired performance.
They are available in designs that are resistant to high abrasion, caustic process media, friction, and so on.
Users can expect static as well as dynamic static function.
They do not extrude or nibble as they pass over ports.
These seals are available in a variety of working pressures and temperatures, and surface speeds.
There are certain piston seals that are available in special compounds that offer an extended seal life. These piston rings are made from glass reinforced nylon that shows a great amount of tensile strength. Thus, if you have a heavy-duty hydraulic or pneumatic application, then the use of a piston seal would ensure the safety of your process and people.
