The application scope of butt-welded flange is as follows:  

One, the length of the workpiece: such as strip steel, profile, wire, steel bar, rail, boiler steel pipe, oil and gas transmission pipeline butt welding.  

Two, annular workpiece welding: such as car rim and bicycle, motorcycle rim welding, all kinds of chain welding, etc.  stainless steel weld neck flange suppliers-GKSTEELPIPE

Three, component welding: simple rolling, forging, stamping or machining parts into complex parts welding, to reduce costs.  For example, automobile direction axle shell and rear axle shell butt welding, all kinds of connecting rod, pull rod butt welding, and special parts butt welding, etc.  

Four, dissimilar metal butt welding: can save precious metals, improve product performance.  For example, the butt welding of the working part of the tool (steel) and the tail (medium carbon steel), the butt welding of the head of the exhaust valve of the internal combustion engine (not afraid of hot steel) and the tail (structural steel), the butt welding of the aluminum copper conductive joint, etc.  

Butt-welded flange mainly refers to the mechanical function depends on the carbon content in the steel, and generally does not increase a lot of alloying elements of steel, sometimes also known as carbon steel or carbon steel.  Connect the pipeline and adhere to the sealing function of the pipeline;  Butt-welded flange connection is widely used in industrial pipelines.  Flange connection is easy to use and can withstand large pressure.  Easy to replace a section of the pipeline;  Carbon steel is also called carbon steel, refers to the carbon content of WC less than 2 percent of the iron carbon alloy.  

Butt welding flange in the practice of production and in use in the development of different methods and technology to manufacture and produce, according to the method and principle of technology, to attack the important value and role of different, in the practice of yield increasing corresponding element in the features and value of carbon steel flange, the use of good characteristics and value.  To facilitate the closure of a section of pipeline.  Easy to open to check the pipeline situation;  This will increase the effectiveness of members to get used to the modern trend, with the global foundry industry.  

Butt-welding flange is one of the flanges, widely used and promoted in the machinery industry, by the user's praise and favor.  The purpose of butt-welding flange is common, the use range is determined according to different characteristics, and it is mostly used in the case of relatively moderate medium conditions, such as low-pressure non-purification compressed air and low-pressure circulating water. Its advantage is that the price is not very high.  Butt-welding flange refers to the flange with a neck and a circular pipe transition and butt-welding connection with the pipe.  Butt-welded flange is not easy to deformation, good sealing, widely used, nominal pressure PN in about 16MPa.  Butt-welding flanges are suitable for pipelines with high temperature, high pressure and low temperature or pipelines with large fluctuations in pressure and temperature. Butt-welding flanges are also used for conveying expensive, flammable and explosive media on the pipeline.  

The sealing surface of butt welding flange can be made into smooth type, concave-convex type and tenon groove type.  Smooth butt-welded flanges have a large amount of application, and the other two kinds of butt-welded flanges are also more common in use.  The main application environment of butt-welded flange is appropriate. It needs to be determined according to the specific situation, to determine the specific use value and performance of butt-welded flange, and to withstand high temperature and high pressure.  Butt-welded flanges are suitable for the connection of steel pipes with nominal pressure not exceeding 2.5MPa.
