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 […]
How to deal with the rough surface of stainless steel flange
Flange surface is smooth and decided the sealing surface of the connection effect, in the usual contact will have many such rough stainless steel flange, it is difficult to seal, so the roughness of the stainless steel flange for sealing effect is very important, here and share with you why roughness determine the connection quality of […]
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, […]
Stainless steel flange production of industrial standards and regulations
Stainless steel flange is a kind of used to connect two pipes connection parts, in the entire plumbing system of stainless steel flange is just a part of the connection parts. Stainless steel flange are classified into the category of the stainless steel flange parts, flange can be connection and some of the water pump, there […]
How to seal stainless steel flange By yaang.com
Because the flexible graphite has plasticity and good packing, when using this kind of gasket to precision machining of flange sealing surface does not need to match, for stainless steel flange sealing surface water; Groove can be adaptive, relatively economy. The gasket is also called flexible graphite composite gasket, metal it is made of salt tooth metal […]
Flange design, casting and sealing by yaang.com
The internal structure of the casting flange is loose and uneven, and the strength and quality are difficult to be guaranteed. The forging molding is more and more energy consumption and high cost. For weeks to continuous distribution, metal grain arranged tight and neat, fast molding, low energy consumption, saving materials, good surface quality, forming […]
The use of the high pressure flange requirements By yaang.com
High pressure flange is used very widely, but its quality requirements are very high, traditional high pressure flange: is the seal (oval gasket, octagon gasket, gasket, etc.) pad plastic deformation to achieve sealing effect and connected to the end of the tube, pipe and the pipe are mutually connected parts, there are holes on the […]
