Seven factors affecting gaskets and packing seals

Factors affecting gasket and packing seal (1) Surface condition of sealing surface: the shape and surface roughness of sealing surface have certain influence on sealing performance, and smooth surface is beneficial to sealing. The soft gasket is insensitive to the surface condition because of its easy deformation, while the hard gasket is greatly affected by the surface […]

How to choose gasket

A, the related factors should be considered when choosing gasket to know: A. to seal of highly toxic chemicals, chooses gasket safety performance is stronger, so as to guarantee; For transporting flammable liquid pipeline system, the need to pay attention to the gasket on the flange of the highest working pressure and temperature to control within a […]

The choice of gasket materials

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow “less-than-perfect” mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials. Gaskets for specific applications, such as […]

There are several types of flange sealing surface by yaang.com

There are three kinds of flange sealing surface model: planar seal face, is suitable for the occasion of pressure is not high, medium non-toxic; Concave-convex sealing surface, suitable for pressure slightly higher occasion; Mortise sealing surface, suitable for flammable, explosive, toxic medium and high pressure situation. Gasket is a kind of can produce plastic deformation, and has […]

Knowledge of flange gasket by yaang.com

Compression spring constitutive relationship, bolt pretension and flange contact with consideration of the nonlinearity of the gasket. From the results of finite element calculation from both inside and outside edge of the flange axial displacement difference (i.e. relative deflection) is then divided by the inner and outer flange diameter difference. Will take over the combined flange, gasket, […]
