The thickness of the corrugated compensator is an important parameter in its design and manufacture, which directly affects the strength, durability and cost of the compensator. The thickness of the corrugated compensator mainly refers to the wall thickness of the corrugated pipe, which will vary according to different applications and design pressures.
Here are some common rules and recommendations for corrugated compensator thickness:
Rectangular corrugated compensator for unpressurized pipeline：
Typically, the thickness is 1.2 mm, and if the diameter is larger than 2000×2000 mm, it can be calculated as 1.5 mm.
Corrugated Compensator for Gas Pipeline：
The corrugation thickness is calculated by pressure, and even if the pressure is small, a double-layer structure is usually employed to enhance its tightness and safety.
Corrugated compensator for pressure-bearing pipeline：
The thickness should be selected according to the technical parameter table to ensure that the compensator can withstand the working pressure in the pipeline.
Circular corrugated compensator：
When assembling, the diameter is less than 2000mm, 1.2mm-1.5mm is recommended, if it exceeds 2000mm, the corrugation thickness is calculated as a single layer of 2mm, unless there are special requirements, it is not recommended to use double layer.
Pressure pipe corrugated compensator：
There are many specifications of wall thickness, such as 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc. The choice is based on the pressure grade of the pipeline, and thicker wall thickness is required under high pressure.
Material selection：
The material of the corrugated compensator, in addition to its working pressure and temperature, should also take into account the corrosiveness of the medium, environmental conditions, and cost and performance balance.
Double or multi-layer bellows：
For high pressure or special operating conditions, a double or more layered bellows structure may be required to increase the strength and reliability of the compensator.
It is worth noting that the thickness of the corrugated compensator is not limited to the above values, and may be adjusted according to specific technical requirements and engineering standards in practical applications. For example, for specific media or extreme operating conditions, thicker bellows may be required to ensure adequate pressure resistance and durability.
When designing and selecting a corrugated compensator, detailed calculations and evaluations should be carried out by professionals with relevant experience according to the specific conditions and requirements of the pipeline system to ensure that the thickness of the selected compensator can meet the requirements of safety and performance.
