Today Western Has More Than 500+ Different Profiles Which We Supply To More Than 400 Clients Worldwide.
We Are Pleased To Supply Our Inflatable Seals To Our Indian Reputed Government Companies Such As ISRO, NTPC, BARC, TNPL, HAL And Many More.
Non-reinforced inflatable seals are made only from elastomers & are mostly extruded constructions; however, they can be molded to meet specific dimensional parameters.They are the preferred option for regular sealing applications as they are relatively affordable and do not compromise on quality and performance.
Molded fabric reinforced inflatable seals are recommended in applications involving extreme pressure/temperature conditions or in rugged environments. The molding process eliminates joints and the fabric reinforcement adds to the seal’s overall strength and resilience. Depending upon the application, one of the following fabrics is chosen
Axially expanding Inflatable Seals have the centerline diameter as the fixed dimension. The Inflatable Seal expands in the perpendicular direction with respect to the diameter. These seals are sometimes also referred to as face seals.
Seals expanding radially outward have the Air Inlet Valves(AIV) typically installed into a channel with the inside diameter (ID) as the fixed dimension.
Inflatable seals with small outside diameters may end up wrinkling with this kind of expansion. Seals expanding radially inward have Air Inlet Valves(AIV) typically installed into a channel with the outside diameter (OD).
Inflatable Seals with circular geometry are the most commonly used seals owing to their wide application. Circular Inflatable Seals are the mostly preferred in manhole covers, hopper seals or in industrial machinery like fluidized bed dryers, autoclaves; where in the machines are made in circular dimensions.
Rectangular Inflatable Seals are very commonly found in door applications like doors for clean rooms, nuclear facility, satellite testing facility, etc. Please note, Western Rubbers’ does not fabricate rectangular seals with tight radiused corners. This is to ensure the seal expansion is not compromised at any point.
A fabric-reinforced inflatable seal is an elastomeric tube molded into a concave, convoluted or flat configuration. It is designed to round out with the introduction of an inflation medium to form a tight barrier between a mounting and striking surface.
An inflatable seal operates by introducing an inflation medium. Upon introduction of the inflation medium, it quickly expands to the striking surface, affecting a positive seal. When the inflation medium is removed, the seal retracts naturally to the deflated molded configuration. This provides clearance for free movement of one or both surfaces.
An inflatable seal has several advantages over other sealing methods: • It provides a leak-proof closure, yet allows clearance when needed. • It simplifies the design of the structure and hardware. • It minimizes the need for close machining and/or fabricating tolerances. • It is not subject to a compression set which negates effectiveness of other seals.
Yes! Essentially all Western Polyrub Inflatable seals are custom rubber seal designs. After over 30-years in business, more than 8000 unique products have been developed. Take a look at all of the unique designs at inflatable seals product category.
It’s important to consider the application’s environment: gas temperature, radiation and abrasion exposure when maintaining your inflatable seal. Learn more about these application environmental considerations.
Generally for nominal pressure applications we suggest customers to avoid fabric reinforced seals so as to avoid high costs. But if your differential pressure requirements are higher than 7-8 Bar then we suggest customers go for fabric.
