Flange pipe fittings are a kind of welded pipe fittings. Such fittings are used to match pipes. Some are processed and some are not processed. Some castings are cast out of the flange together. The welding is post-processed. The factory can process it, and it can also be processed at the construction site. There are big and small flange pipe fittings, but also elbow and tee flange pipe fittings. Its materials are also diverse, including carbon steel, alloy steel, stainless steel, etc.
1. Flange is also called flange plate or flange plate. The flange is the part that connects the pipe and the pipe to each other and is connected to the pipe end. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. The flange is divided into screw connection (wire connection) flange and welding flange.
2. Connect the pipe into a pipe part. According to the connection method, it can be divided into four types: socket-type fittings, threaded fittings, flange fittings and welded fittings. Mostly made of the same material as the tube. There are elbows (elbows), flanges, three-way pipes, four-way pipes (cross heads) and reducers (large and small heads). The elbow is used in the place where the pipe turns; the flange is used to connect the pipe and the pipe to each other, and is connected to the pipe end. Diameter pipes are used where two pipes of different diameters are connected.
