Talking about the choice of bolt diameter and area

The design of the bolt includes selecting materials, calculating the bolt diameter and number, and determining the bolt size according to the thread and bolt standards, and finally checking the bolt spacing. Bolt load After the gasket material, type and size are determined, the preload and operation loads are calculated to determine the minimum bolt area required, and the actual bolt area selected should be no less than the required bolt area.

When selecting the bolt diameter, it should not be too small. If the bolt diameter is too small, it is easy to be broken. Generally, the bolt diameter is larger than M12. Moreover, in the case of high temperature and high pressure, especially in the case of pressure fluctuations, full-thread or equal-strength studs should be used.

The design of the flange is carried out by trial calculation. Generally, the standard flange is used as a model to assume the flange cone or flange ring size, and the flange torque and the flange stress are calculated.

If the stress value differs greatly from the corresponding allowable stress, the size of the flange neck or flange ring must be adjusted, and then the calculation process is repeated until the stresses tend to be full stress, so that the strength of the material can be fully utilized. Performance, and can achieve the purpose of flange optimization design. In addition, under the premise of meeting the requirements, the diameter of the center circle of the bolt should be as small as possible; the gasket load should be controlled as much as possible in the gasket design; try to make the stress of the flange full of stress. This can achieve the purpose of flange optimization design.

Polishing Buff Wheel

Bias Airway buffing wheel, also called as airway buffs, airflow buffs, Ventilated buffs. The special air folded structure brings bias airway buffing polishing wheel strong cutting force, high brightness, fine finishing, can cool the workpiece surface at a very short time. Make airway buffing polishing wheel widely use on metal and non metal products polishing, such as wood, stainless steel, aluminum, copper etc. Involved in variety of industries: furniture, automobile spare part, hardware, building materials,etc.

Airway buffs are a type of buffing and polishing wheel that is made up of multiple plys of cotton Cloth attached to a steel center plate. Each cloth layer of these 16-ply wheels is attached to the steel plate in a way that forces the cotton to form pleats.
High-speed buffing and polishing wheels can create a lot of heat from the constant friction of the wheel, surface being buffed, and Polishing Compound grinding at the same time. The fold are designed to increase airflow so that you can buff and polish at a lower temperature. This allows you to work continuously longer than traditional polishing wheels, extends the overall serving life of the airway buff, and lowers the chance of causing damage or burn to the object you are polishing.

The different colors of airway buffs are not there to let you work with your favorite color. Each of these colors has a different firmness/softness of the cloth pieces which are meant for different steps in the polishing process. You should also consider pairing each color buffing wheel with the appropriate color buffing compounds.
