Product information of internal and external pressure balanced bellows: Example: .*
means: working pressure is ., diameter, wave number is, internal and external pressure balanced corrugated compensator connected to the pipe.
Instructions for use:
The internal and external pressure balance bellows compensator can compensate for the axial displacement in the pipeline system, and the internal pressure thrust balances itself. This structure can be used in pipelines with high objects where it is not suitable to install fixed brackets.
Calculation of the force exerted by the internal and external pressure balanced corrugated compensator on the support:
Axial elastic force*(*)
In the formula: - Axial stiffness
- Axial actual Deformation amount
- Calculation coefficient, when pre-deformation (including △)/, when no pre-deformation is performed.
Structural Features
The internal and external pressure balanced expansion joint is composed of an internal pressure expansion joint and an external pressure expansion joint.
Precautions for installation and use:
Keep the drain outlet downward during installation.
After on-site installation, the tie rod must be removed.
During installation, the medium flow direction should be consistent with the flow direction mark of the pipe expansion joint.
The internal and external pressure balance bellows is composed of a working wave of internal pressure and a balance wave of external pressure. It is small in size and its column instability wave number is doubled compared to the straight tube pressure balance compensator because the two sets of bellows in the middle It has good stability under external pressure.
Product features of internal and external pressure balancing bellows: multi-directional compensation, which can provide large multi-dimensional compensation in a small size range, low noise and energy saving, which can effectively reduce the noise and vibration of fans and other systems and save energy. It consumes no reverse thrust, and the main material is fiber fabric. The weak transmission prevents the use of larger supports for the pipelines and equipment on the project, saves a lot of materials and labor, and improves the safety of the equipment and systems. The internal and external pressure balance bellows are made of organic materials. Coated with silicon, fluorine and other polymer materials, it has excellent high temperature resistance, corrosion resistance and sealing performance, anti-fatigue and anti-aging. Simple installation and easy replacement. No high-demand alignment is required. No lifting equipment is required during replacement. short time.
