Product description
Stainless steel expansion joint, also known as stainless steel bellows, stainless steel compensator, metal bellows expansion joints, stainless steel expansion joints and metal bellows, are mainly used to compensate for axial displacement. Stainless steel expansion joint can also compensate for axial displacement or synthesis of axial displacement and lateral displacement. Metal bellows expansion joints have the capacity to compensate for angular displacement.
Features
Nominal diameter: DN100-DN3000 (mm)
Design pressure: 0.1 ~ 2.5 (Mpa)
Design temperature: -20℃~ 450℃
Connection: flange / weld
Fatigue life: 1500 times
Steel expansion bellows classification
1) According to whether can absorb piping within the medium pressure generated by the thrust (blind plate force), steel expansion bellows can be divided into no constraint expansion bellows and constraint expansion bellows;
2) According to the displacement type of expansion bellows, it can be divided into axial type, horizontal type expansion bellows, and angular type expansion bellows and pressure balance type expansion bellows.
Advantages
- The simplest expansion joint to absorb all the movements of the pipe section
- The flow direction is not modified
- The lower cost of expansion joints
