Butt weld flanges are widely used in different industries, this is one of the popular type of industrial flanges. Younglee is a leading manufacturer of various flanges<\/strong> including butt weld flange. Here this article is the most detailed introduction about butt weld flanges. \"Butt<\/a><\/p>\n

The range of butt weld flange use is determined according to different characteristics. They are mostly used in the case of moderate medium conditions, such as low pressure non-purifying compressed air and low pressure circulating water. Its advantage is that the price is cheaper. Butt weld flanges are suitable for connection of steel pipes whose nominal pressure does not exceed 2.5MPa. The sealing surface of butt weld flanges can be made into three types of smooth, concave and convex. Smooth butt weld flange application of the largest amount, the other two methods of butt weld flange is also common in use.<\/p>\n

Butt Weld flange is not easily deformed, with well sealed, so they are widely used. They have the corresponding rigid and elastic requirements and a reasonable butt welding thin transition, welding seam from the joint surface distance, so the joint will not be affected by the welding temperature deformation. They have a more complex body structure, so they are suitable for pressure or temperature fluctuations in the pipeline or high temperature, high pressure and low temperature pipe, generally used for PN greater than 2.5MPa pipe and valve connections; also used to transport prices Expensive, flammable, explosive medium on the pipeline.<\/p>\n

Butt Weld flanges are used for connecting flanges and pipes, including many types and models. They are mainly used in welding technology and perform well in service and performance. They have reasonable structure, high strength and rigidity, Withstand high temperature and pressure and repeated bending and temperature fluctuations, reliable sealing, butt flange designed for nominal pressure of 0.25 ~ 2.5MPa is with concave and convex sealing surface. The main application environment of butt weld flange should be appropriate, this need to be determined according to the specific circumstances to ensure the specific use of welded flange of the value and performance, withstand high temperature and pressure.
\nButt weld flanges, especially for SAE butt weld flanges, are generally made by forgings or forging processes. When using steel or steel manufacturing, the following requirements must be fulfilled:<\/p>\n

    \n
  1. Finished Butt Welded flange should be ultrasonic flaw detection, no denomination defects;<\/li>\n
  2. Material should be cut along the direction of the steel strip into a bar, welded into a ring by bending, and the surface of the steel ring to form a cylindrical surface. Do not use steel plate directly machined into a neck butt weld flange;<\/li>\n
  3. The butt weld ring should be fully welded through the weld;<\/li>\n
  4. The butt weld ring should be post-weld heat treatment, and for 100% ray or ultrasonic flaw detection and ray inspection in line with JB4730 (or equivalent standards ) Class II requirements, ultrasonic flaw detection in line with JB4730(or equivalent standards ) Class I requirements.<\/li>\n<\/ol>\n

    In piping engineering, flanges are mainly used as pipe connectors. The SAE flanges are used to connect hydraulic pipes. Flanges of different pressures have different thicknesses and use different bolts, pumps and valves. When connected with pipes, the parts of these equipment and equipment are also made into corresponding flange shapes, also called flange connections. Two flat surfaces are bolted together at the same time. Connection parts that are closed at the same time, commonly referred to as “flanges”, such as ventilation ducts, may be referred to as “flanged parts”. But this connection is only a part of the equipment, such as the flange and the pump connection, it is not good to pump called “flange parts.” Smaller, such as valves, can be called “flange parts.”<\/p>\n

    SAE butt weld flange<\/a> is one of the typical type of hydraulic SAE flanges<\/a>, while SAE flanges are one of the popular types of flanges, which are widely used in hydraulic systems and other applications in various industries. This product win great praise and favor from their users.<\/p>\n","protected":false},"excerpt":{"rendered":"
