What is the difference between rubber flexible joints and metal flexible joints

Metal flexible joints are made of metal, formed through high-precision plastic processing of seamless or longitudinally welded stainless steel pipes. They have excellent high-temperature resistance and corrosion resistance and can withstand temperatures above 200 degrees Celsius. They belong to the second generation of pipeline compensators.


Rubber flexible joints, on the other hand, are made of rubber and adopt a multi-layered spherical structure with strong vibration absorption and good noise reduction effects. They can withstand higher working pressure and have strong resistance to explosions. The flexibility of rubber allows it to effectively compensate for compression, tension, and torsional deformation. The joints can be connected using flanges or threaded joints that can rotate 360 degrees, making installation more convenient and flexible.

The main body is made of polar rubber, which has good resistance to heat, oil, acid, and aging. They belong to the third generation of pipeline compensators, with more comprehensive product functionality.


The connection methods for metal flexible joints with pipes generally include flange connection, threaded connection, clamp connection, and welding connection.

 Rubber flexible joints are typically connected to pipes using flange connection, threaded connection, and clamp connection.
