How can I choose the right flange dimensions?
The selection of the right dimensions of the flange is often easier than you can expect, as most flange sizes are predetermined and regulated according to the National Set of Standards. In the United States, the American company of mechanical engineers (ASME) sets the regulations governing flanges. If the dimensions of the flange you need correspond to the existing ASME flange, the dimensions are already designed and available to you. Most of the flanges you can encounter have already been created and have shown that they fit and work properly. The size of the flange
may vary considerably. Fortunately, most countries maintain standards that usually provide flanges for us. For example, ASME oversees American standards, while the German control body is known as DIN. This is an English translation for the standardization of the German Institute. For example, the total size of the defect can help determine how many screws you might need, as well as how fat it should be a flange. In other wordsWatch more or larger screws than a narrow flange.
further consideration in selecting the right dimensions of the flange is the weight and/or pressure associated with the connection associated with the flange joint. Flanges that should have a large amount of pressure, such as the steam pipes in the factory, must maximize the pressure on the clamping. Increasing the number of screws around the pipeline will achieve this target. If the screws are distributed too far apart, there is an increased risk of leakage between them.
If you want to help illustrate this idea, imagine a blanket of a picnic on a windy day. Placing rocks in four blankets will help hold it. High winds could still increase the gaps along the long pages. The division of this dimension and the location of the four more rocks between the rocks in the corners would strengthen the power of holding the blanket down. The same idea applies when attempting to maximize the clamping pressure of the flange assembly.
pTerry you are still not sure how to choose the best flange dimensions, contact the manufacturer flanges. Most dimensions used in flanges and flange systems are already determined. Consultation with an engineer can also help if the choice involves heavy loads, high pressures or configurations that are not common, such as those covered by ASME.
