Hangzhou Flat Washer Factory, the factors of gasket selection + seven precision stamping core technology patents

The production staff in charge of the Hangzhou Flat Washer Factory said that the important factors affecting the selection of gaskets is not an easy task. Especially in the selection of gasket sealing materials, many factors must be considered. The following Xiaoshuo takes you to understand the selection factors: (1) Temperature In most of the selection process, the temperature of the fluid is the primary consideration. This will quickly narrow the selection, especially from 200°F (95°C) to 1000°F (540°C). When the system operating temperature reaches the limit of the maximum continuous operating temperature of a particular gasket material, a higher-level material should be selected. This should also be the case under certain low temperature conditions. (2) Application The most important parameters in the application are the type of flange and the bolts used. The size, number, and grade of bolts in the application determine the payload. The effective area to be compressed is calculated from the contact size of the gasket. The effective gasket sealing pressure can be derived from the load of the bolt and the contact surface of the gasket. Without this parameter, you will not be able to make the best choice among many materials. (3) Medium There are thousands of fluids in the medium, and the corrosiveness, oxidation and permeability of various fluids vary greatly. Materials must be selected based on these characteristics when selecting a model. In addition, the cleaning of the system must also be taken into consideration to prevent erosion of the gasket by the cleaning fluid. (4) Pressure Each type of gasket has its highest ultimate pressure. The pressure-bearing performance 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 fluctuates frequently, you need to know the details in order to make a choice. (5) PT value The so-called PT value is the product of pressure (P) and temperature (T). The pressure resistance of each gasket material is different at different temperatures and must be considered comprehensively. Under normal circumstances, the gasket manufacturer will give the maximum PT value of the material.
