Description

Inflatable static seals

Inflatable static seals are silicone tubes of different hollow sections which are inflated to expand and adhere to a surface in order to ensure a proper sealing effect.

Some typical applications are: container doors, doors and moving partitions of structures that have to be sealed, machines with big top covers or doors, and generally big openings with irregular shapes. Inflatable seals can also be used as temporary seals during maintenance operations, i.e. on big shaft when working on dynamic seals.

The tube’s section can be manufactured in different geometries, shapes and dimensions. These sections are accurately vulcanized together to obtain the needed shape with an internal air chamber that can be inflated through a pneumatic valve.

 

DICHTA’s personnel will verify the operating conditions and material, will evaluate the type of seal and of pneumatic valve as well as all other necessary working parameters: inflatable static seals are not standard and therefore are realized on specific customer’s demand.
 

 

Static seals

Static seals are silicone tubes of different hollow sections which use their elasticity to provide the needed sealing effect. The tube is mechanically compressed between the surfaces and adheres by sealing the whole system.

The standard compound is a silicone rubber suitable for continuous exposure to water vapor and complies to the norm FDA CFR 21 parts 170-199 Item 177.2600. Its standard colour is red, but with a minimum order quantity it can be provided in other different colors.

The shapes and the profiles are manufactured according to customer's specifications (round, squared, w/wo retaining base) and can vary from very small to big dimensions. These seals can be delivered split or vulcanized. The joint will be processed on a grinding machine to ensure a top quality surface of the tube.
