Product description
Overview
- 1 Bellow made of stainless steel
- 2 Gunmetal or silicon bronze press connector
The compensator is suitable for absorbing axial movements in pipeline installations. Do not use if radial loads occur.
Handling
Storage
For storage, comply with the requirements specified in the applicable regulations, see Regulations from section: Storage :
Store components in a clean and dry place.
Do not store the components directly on the floor.
Assembly information
Mounting conditions
Installation and mounting instructions
Do not install the compensator under torsion (twisted) or place under strain.
Protect the stainless steel bellows from mechanical damage.
The compensators are not rated to withstand strain from lateral movement (lateral and/or angular).
The compensators do not need to be pre-stressed prior to assembly.
Pipe guide and bearing
- 1 Guide
- 2 Compensator length
- 3 Expansion compensation
- 4 Fixed point
The guide on both ends of the compensator must not be removed more than 2 x DN (pipe nominal width). The next guide should have about ⅔ of the prescribed fixing distance.
Gliding and fixed points
Adhere to the maximum distance for gliding points (pipe clamp distance). The pipe sections to be compensated must be aligned (coaxial pipe thrust).
Provide fixed points of sufficient strength at the pipe ends and branches. Install only an axial compensator between two fixed points.
The maximum fixed point load in (Newtons) is calculated using the following formula:
Pressure in bar x effective bellows cross-section x conversion and safety factor (Fmax= p x A x 20)
Compensator | Pressure P | Effective bellows cross-section A | Max. fixed point load Fmax | Expansion compensation * | |
