DESCRIPTION:

Wespo fabric reinforced inflatable seal is a completely molded seal which is built around the same operating principles as a regular inflatable seal made ,


The bonding of fabric between two layer of rubber increase seal strengths and helps to maintain or increase uniform internal pressure by which the inflatable seal operate at  higher pressure.




There are several conditions which compels  to use of a fabric reinforced seal. However, the common reason for using a reinforced seal is to achieve higher pressures.

  1. High working pressures

  2. Extremely heavy loads

  3. Frequent uniform operation

  4. Cost doesn’t matter 

  5. Installations is time consuming 


Today western polyrub stand out as leading manufacturers of fabric inflatable seal from 30 years ,wespo make inflatable seals with hand built and fully moulded with fabric reinforcement inside ,make inflatable seal so tough and performs constantly which insure reliable inflation across striking surface ,in some special cases wespo has developed seal can withstand pressure up to 50 Kgcm2

HIGH PRESSURE INFLATABLE SEAL FOR OFFSHORE APPLICATIONS 



Western polyrub has developed technology to used fabric reinforced inflatable seal in a number of critical applications including offshore production, storage and offloading (FPSO); anchoring drill rigs to the seabed; gas loading systems; pipeline welding; and watertight doors and panel

High -pressure inflatable seals are designed to fit in metal retaining grooves, allowing axial, external radial and internal radial expansion, These seals typically can withstand pressures of up to 8 bar, and are suitable for sealing clearances from 2-10mm.

Fabric reinforced inflatable seal widely used in pulp and paper and nuclear plant 

Wespo Quality control and testing

  1. Special tooling design which make seal accurate and flash less

  2. cycle testing of inflatable seals in high pressure environments (testing both profile stress and leak rates )

  3. seal identification codes relating to production record which includes compound batch , cure time ,Food grade tc no , data sheet etc

  4. Wsds Anti Static seal for atx test properly to meet stringent surface resistance requirement

  5. custom make seal , if required then test over 10000cycles (inflate and deflate) / day dependant on volume of seal

  6. Testing of fabric on tensile machine before production


Wespo offers technical guidance to decide  the appropriate design, manufacturing process and material comparison and formulation wespo fabric inflatable must withstand environmental factors and perform using air liquid or gas controlled mechanisms under pressure. The environment and structure will affect the choice of reinforcing fabric.

Wespo unique design and quality manufacturing process, as well as our different heat moulded fabric reinforcement system, proven that wespo seals are the safest available and best to use without any problem

Failure of seal 

There are five reasons why inflatable seal  fail

  1. media

  2. temperature

  3. application

  4. pressure

  5. fitment


Sometimes normal inflatable seal can work in place of costly fabric reinforced seal
