In order to determine the sealing behavior of gasket materials in particular, tightness tests are carried out in advanced laboratories close to the conditions found in practice. To determine the sealing failure of equipment or material that needs to be sealed, a different test method is required to determine the uniformity of sealing behavior. Detection of the leak in its early stages and then the precise determination of the leak rate is accomplished by conductivity measurements. The effectiveness of a gasket depends on sealing in case of gasket and adhesion in case of compression. Gaskets attach to equipment used in a wide variety of industries, including chemicals, water supply, paper manufacturing, food processing and many other applications.
In general, the following points are emphasized in the leak tests:
There are various types of gaskets, each with different functions, used for sealing purposes. Compression seal, diaphragm seal, ferrofluid seal, flange seal, mechanical seal, Dowty seal (integrated seal, Bridgman seal (piston sealing mechanism), hydrostatic seal, hydrodynamic seal, inflatable seal, radial shaft seal, wiper seal, dry gas seal and Bodok gasket (a special gas-tight gasket for medical applications) are the most commonly used gasket types.
However, other than gaskets, there are other systems that provide sealing. For example, induction seal or lid sealant, adhesive sealant, O-ring, heat seal, hose couplings, hermetic seal and container lid.
The purpose of sealing qualification tests is to determine the effectiveness of sealing components from their internal volumes, ie the insulating strength of internal volumes. Sealing failures either allow the ingress of contaminants, reducing the effective life and reliability of the equipment, or cause the stored liquid or gaseous content to flow out of the container.
Our organization also provides impermeability qualification testing services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
