International flanges are generally used for connection, so they are often connected with some pipes. But some people don't know much about its way. In fact, the national standard flange connection is to fix two pipes, pipe fittings or equipment on a flange first, and add flange pads between the two flanges. At this time, you can fasten them together with bolts. In this way, it is completed, so it is relatively simple. But what you need to know is that some pipe fittings and equipment have their own flanges, which also belong to flange connection.
In short, as long as there are pipelines, there must be international flanges. After all, it is an important way of pipeline construction. If it is used, it can withstand greater pressure. Flange connection is widely used in industrial pipelines. Generally used in families, because the diameter of the pipe is relatively small, we sometimes can't see the international flange, but how do you say that in a boiler room or production site, there are flange connected pipes and equipment everywhere. This is really a widely used product.
