High Pressure Butt Welding Flange

High quality high pressure butt welding flange is offered by China manufacturer SN Valve. High-pressure butt-welding flanges are the type of flanges that are butt-welded to the pipeline through the long neck, and their structural features include the long neck, the flange face and the welding bevel. The design of the long neck part makes the connection between the flange and the pipe stronger and can withstand higher pressure and temperature. The flange face is used to make contact with the sealing gasket to form an effective seal. The welding bevel is designed to facilitate the welding operation between the flange and the pipe.

Product Description

Function and Application

Sealing performance: High pressure butt-welding flanges form a reliable seal through the close contact between the flange face and the sealing gasket, preventing the leakage of medium and ensuring the safe operation of the pipeline system.
Pressure-bearing capacity: due to its structural characteristics and welding method, the high-pressure butt-welding flange can withstand high pressure and temperature, and is suitable for high-pressure, high-temperature or high sealing requirements of the working conditions.
Convenient connection: high-pressure butt-welding flanges are connected with pipelines by welding, which is easy and fast to install and the connection is firm and reliable.
Application scope: High pressure butt-welding flanges are widely used in petroleum, chemical, shipbuilding, pharmaceutical, metallurgical and other industries for connecting pipelines and equipments to ensure the integrity and safety of pipeline systems.

Types and Specifications

High pressure butt weld flanges can be categorized into necked high pressure butt weld flanges (also known as high neck flanges) and other types of high pressure butt weld flanges according to their structural forms. High pressure butt welding flanges with necks have longer necks, which can provide better support and sealing effect. In addition, high pressure butt welding flanges can be categorized and selected based on parameters such as material, pressure level and connection size.
