The shape and size of ordinary carbon steel flanges are accurate, the processing volume is small, and the cost is low. However, the cast flange will have holes, cracks and impurities, and the cast internal structure is poor. The advantage is that it can have more complex shapes and is less expensive to produce.

Flange is also called flange or flange. The part that connects the pipe to the pipe, connected to the pipe end. There are holes on the flanges, and bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flange is a disc-shaped part, the most common in pipeline engineering, flanges are used in pairs. In pipeline engineering, flanges are mainly used for the connection of pipelines.

The company mainly produces forged carbon steel flanges: flat flanges, sliding flanges, slotted flanges, galvanized flanges, square flanges and other special-shaped flanges
The connection method of the national standard flange!
Another meaning of the national standard flange is: the flange plate produced according to the size and tolerance range required by the national standard is different from the flange sheet produced not according to the standard size, which is also called the second standard flange (some people call it non-standard flange). is incorrect), usually some unscrupulous merchants will reduce the flange thickness and outer diameter to save materials, and use scrap steel or scrap steel to process flanges, usually this steel is chemical composition and mechanical Scrap whose performance does not meet the standard, and even the use of private steelmaking in black steel plants to produce flanges. The steelmaking technology used in this private steelmaking is outdated and cannot guarantee mechanical properties and welding performance. It may not be able to be welded with steel pipes during use, or The steel itself has cracks, pores, etc., and it will leak water after welding.
Therefore, try to use national standard flanges when purchasing flanges. If the funds are limited to choose the second standard flange, you must carefully observe and measure the flange size and test its material to avoid being fooled.
The national standard flange (flange) connection is to fix two pipes, pipe fittings or equipment on a flange plate first, add flange pads between the two flange plates, and fasten them together with bolts. connect. Some pipe fittings and equipment already have their own flanges, which are also flanged connections. Flange connection is an important connection method in pipeline construction.
Flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used. In the home, the pipe diameter is small, and it is low pressure, and the flange connection is not visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
According to the connection method, the flange connection type can be divided into: plate flat welding flange, flat welding flange with neck, butt welding flange with neck, socket welding flange, threaded flange, flange cover, butt welding ring with neck Loose flanges, flat welding ring loose flanges, ring groove face flanges and flange covers, large diameter flat flanges, large diameter high neck flanges, eight-character blind plates, butt welding ring loose flanges, etc.
