Connection form
Threaded flange is a non welded flange that processes the inner hole of the flange into a pipe threaded flange and realizes the connection with the threaded pipe.
Characteristics and features
Compared with flat welding flange or butt welding flange, threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines that are not allowed to be welded on site. Alloy steel flange has sufficient strength, but it is not easy to weld, or the welding performance is not good. Threaded flange can also be selected.
Under the condition that the pipeline temperature changes sharply or the temperature is higher than 260 ℃ and lower than - 45 ℃, it is recommended not to use threaded flange to avoid leakage.
Procurement proposal
1: It is recommended to purchase from a regular threaded flange manufacturer, which needs a certain production scale;
2: Flange manufacturers need to provide material inspection reports and other relevant data of threaded flanges;
3: The threaded flange plate shall be provided with corresponding specification and model steel seal and identification;
Flanges include: forged steel flanges of carbon steel, alloy steel, low-temperature steel, stainless steel, dual phase steel and nickel base alloy, steel forgings for various boilers and pressure vessels, as well as various machinery and ship forgings.
Flange plates include plate flat welding flange, butt welding flange, neck flat welding flange, neck butt welding flange, loose sleeve flange, large mechanical flange, pressure vessel flange, socket flange, screw flange, flange cover, spectacle blind plate, pipe plate, plug, manhole, wind power flange, pipe flange and CNC precision flange.
