Flanged copper bushing, as a key component in mechanical connections, has attracted much attention due to its diversity and importance. In mechanical design and engineering applications, the correct selection and use of flanged copper sleeves can significantly improve the stability and durability of the system. The following is a detailed analysis of the classification of flange copper sleeves:

Classified by connection type

Flat welded flange copper sleeve: this is the most common type of flange, its welding neck is low, the manufacturing cost is relatively low, but it is not suitable for high temperature, high pressure and high vacuum requirements.

Copper sleeve with neck flange: The higher neck of this flange provides better strength and rigidity, suitable for withstand higher pressure and temperature fluctuations, often used in more demanding working environments.

Butt welded flange copper sleeve: This flange has the highest strength and stiffness, suitable for high temperature, high pressure and low temperature applications, is the most widely used in the industrial field of a flange.

Classified by seal form

Flat sealing flange copper sleeve: the sealing surface of this flange is smooth plane, suitable for low pressure, low temperature conditions, is the simplest sealing form.

Face sealing flange copper sleeve: the sealing surface of this flange has a raised ring, suitable for medium pressure, medium temperature conditions, is one of the more common sealing forms.

Concave and convex sealing flange copper sleeve: This flange combines the design of protruding surface and concave surface, can provide better sealing effect, suitable for high pressure, high temperature and need higher sealing performance.

Classification by material

Carbon steel flange copper sleeve: This flange is mainly made of carbon steel, has good strength and toughness, suitable for most conventional working conditions.

Stainless steel flange copper sleeve: Made of stainless steel, it is particularly suitable for corrosive environments such as the chemical industry and seawater applications.

Alloy steel flanges with copper sleeves: Manufactured using a variety of alloy steels for industrial applications with special pressure or temperature conditions, such as the oil and gas industry.
