Single Arch Type Stainless Steel Bellows Compensator for Industrial Pipeline

The main difference between the non-flanged metal corrugated compensator (typically referring to the direct welding type corrugated compensator) and the flanged compensator lies in the connection method. Its characteristics include: 
Connection method: Connected directly to the pipeline by welding, eliminating the need for flanges and bolts. 
Structure: Usually consists of components such as bellows and end pipes. 

Applicable scenarios:

A piping system with higher sealing requirements can benefit from welding as it can reduce leakage points. 
In situations where space is limited and it is difficult to install flange bolts. 
The working condition involves strong medium corrosion and the flange connection is prone to damage. 
Advantages and Disadvantages: 
Advantages: Excellent sealing performance, more compact structure, usually lower manufacturing cost, and potentially better fatigue resistance. 
Disadvantages: Installation and disassembly are rather difficult and require welding operations; it is inconvenient to replace the compensator individually. 
?? Selection and Installation Tips 
Correct selection: 
According to the displacement direction of the piping system (axial, lateral, angular) 
The type of compensator is selected based on the temperature, pressure and medium characteristics. For instance, the un-restrained type of bellows compensator is mainly used for axial compensation of the pipeline. 

Avoid the situation where incorrect model selection leads to the compensator being unable to meet the actual compensation requirements of the pipeline. 

Ensure welding quality: 
When welding, it is necessary to protect the corrugated tube to prevent the welding slag from splashing onto the surface of the tube shell or causing mechanical damage to the corrugated tube. 
This is to avoid compromising the sealing performance and corrosion resistance. 
The auxiliary positioning components on the compensator need to be removed as per the regulations after the installation is completed. 
Otherwise, it will restrict the compensation activities and cause them to fail. 
Criteria for consideration: 
Pay attention to whether the working temperature is within the range that the compensator can withstand. 
To prevent the deterioration of material properties. 
In an environment with corrosive media, an appropriate material for the compensator should be selected. .
