Gasket sealing occupies a very important position in modern industrial enterprises, and the good or bad sealing is directly related to the continuity of production, safety of property, energy saving and environmental protection as well as people’s physical and mental health, so the development of washer is getting more and more attention. With the rise of modern industry, especially the petroleum and chemical industries, atomic energy industry and large power stations, pressure vessels are developing in the direction of high temperature, high pressure, high vacuum, deep cooling and large size, multi-series, which constantly put forward new requirements for gasket sealing, and various new materials and structures are emerging, and their sealing performance is also very different. In addition, pressure fluctuation, temperature change, bolt preload slack, flange tilt, misalignment, sealing surface defects, media corrosion will have a great impact on the sealing effect. Therefore, how to correctly select the appropriate gasket according to the working conditions and how to correctly install is the key to ensure the sealing effect. [1]

Washer Selection

Important factors influencing gasket selection Gasket selection is not an easy task, especially in the selection of gasket sealing material, many factors have to be considered. The variables that occur at the flange connection are seemingly endless, and all of these uncertainties affect the gasket’s sealing effectiveness. In the past, the parameters “TEMP” (temperature, application, medium, pressure) seemed to be sufficient. But today, the quality of the flange machining, the amount of bolt fillet embedment, the flange rotation, the bolt tensioning, the filler of the medium and the flange surface treatment all influence the gasket sealing effect. Therefore, various parameters must be considered in order to make an appropriate selection.

(1) Temperature

In most selection processes, the temperature of the fluid is the primary consideration. This will quickly narrow the selection range, especially when going from 200°F (95°C) to 1000°F (540°C). When the system operating temperature reaches the maximum continuous operating temperature limit for a particular gasket material, a higher grade of material should be selected. This should also be the case in certain low temperature situations.

(2) Application

The most important parameters in the application are the type of flange and the bolts used. The size, number and grade of the bolts in the application determine the payload. The effective area to be compressed is calculated from the gasket contact dimensions. From the load of the bolts and the contact surface of the gasket the effective gasket sealing pressure can be derived. Without this parameter, it will not be possible to make the best choice among the many materials available.

(3) Washer supploer

There are thousands of fluids in the medium, and the corrosiveness, oxidation, and permeability of various fluids vary very much. Selection must be based on these characteristics when selecting materials. Also the cleaning of the system must be taken into account to prevent the erosion of the gasket by the cleaning fluid.

(4) Pressure

Each gasket has its own maximum pressure limit, and the pressure-bearing capacity of the gasket decreases with the increase of the material thickness, the thinner the material, the greater the pressure-bearing capacity. The selection must be based on the pressure of the fluid in the system. If the pressure often fluctuates drastically, it is necessary to know the details in order to make a choice.

(5) PT value

The PT value is the product of pressure (P) and temperature (T). Each gasket material has a different pressure resistance at different temperatures and must be considered. In general, the manufacturer of the gasket will give the maximum PT value of the material. [1]

Classification

Asbestos rubber sheet washer

Asbestos rubber sheet washer are made of asbestos fibers, rubber as the main raw material supplemented with rubber compound and filler, through the process of mixing and stirring, hot roll forming and vulcanization. Asbestos rubber washer can be divided into common asbestos rubber washer and oil resistant asbestos rubber washer according to their formulations, process performance and applications. According to the temperature and pressure, they can be divided into low pressure asbestos rubber washer, medium pressure asbestos rubber washer and high pressure asbestos rubber washer. Suitable for sealing water, water vapor, oil, solvent, medium acid and alkali, asbestos washer are mainly used in the sealing of medium and low pressure flange connections.

Installation requirements

Sealing Gasket Washer

1、The sealing surface of the sealing gasket and flange shall be cleaned and shall not have any defects such as scratches and spots that affect the sealing performance of the connection.
2、The outer diameter of the gasket should be smaller than the flange sealing surface, and the inner diameter of the gasket should be slightly larger than the inner diameter of the pipe, and the difference between the two inner diameters is generally taken as two times of the thickness of the gasket to ensure that the inner edge of the gasket does not extend into the container or pipe after pressing, so as not to obstruct the flow of fluid in the container or pipe.
3, seal gasket preload should not exceed the design provisions, so as not to over-compress the gasket loss of resilience.
4, seal gasket pressure, the best use of torque wrench. For large bolts and high-strength bolts, it is best to use hydraulic tightener. Tightening torque should be calculated according to the given gasket pressure, the size of the hydraulic tightener oil pressure should also be determined by calculation.
5, the installation of the gasket, should be in order to tighten the nuts in turn. But should not be screwed once to reach the design value. Generally should be at least 2 to 3 times in order to seal the gasket stress distribution evenly.
6, for flammable, explosive media pressure vessels and pipelines, change the sealing gasket should use safety tools, so as to avoid tools and flanges or bolts touching, sparking, resulting in fire or explosion accidents.
7, the pipeline, such as leakage, must be lowered to deal with the pressure before replacing or adjusting the installation of washer, it is strictly prohibited to operate under pressure.

Special installation requirements

1、When installing the sealing winding gasket with the flange of the abrupt plane, attention should be paid to ensure that the seal is concentric with the pipe, and the outer strengthening ring is generally used to contact the inner circumference of the bolt for positioning, and eccentric installation is not allowed. When installing the basic winding gasket in the flange with tongue and groove face sealing surface, care should be taken to maintain the same gap with the groove wall surface.

2、When installing the metal clad gasket with narrow width, a steel plate of certain thickness should be placed on the outside of the gasket and then pressed against the flange, so that the clad packing inside the metal gasket will not be pressed and swell the interface (or hitch) of the metal shell and damage the metal clad gasket.

3、When the working temperature of the flange is higher than 200℃, the sealant should be applied between the sealing surface of the flange and the sealing gasket to prevent the sealing gasket from sintering with the sealing surface of the flange under high temperature, which will add trouble to the maintenance and replacement of the sealing gasket.

4, the sealing surface is not flat, can be coated with sealant on the sealing surface and then install the gasket. Sealant is generally composed of manganese dioxide, lead, graphite powder and boiled flaxseed oil (dry oil). According to the sealing medium, working temperature and medium pressure and other conditions, choose the appropriate type and grade of liquid sealant.

5、For the installation of octagonal metal ring gasket, when the processing of metal ring gasket and flange sealing groove is not ideal, close fitting can be achieved by matching research. For large diameter metal ring washer, it is more difficult to match the research, and sealant can be used to fill the small unevenness of the metal surface.
