Multidimensional Thermal Displacement Flexible Compensator Non Metal Expansion Joint For Power Plants

DINKONDA GLOBAL Power Plants Special Multidimensional Thermal Displacement Rectangular Non-metallic Flexible Composite Skin Compensator Non-metallic Expansion Joint

Product Overview
Rectangular non-metallic compensators are mainly used in rectangular flue and hot air duct systems in industries such as power plants, metallurgy, cement, and chemical engineering. They rely on flexible composite skins to absorb multidimensional thermal displacements in the axial, transverse, and angular directions of pipelines, while also providing vibration reduction, noise reduction, compensation for installation deviations, and resistance to flue gas corrosion. The product has a rectangular flange structure and is equipped with an internal guide tube and a limit rod. It is suitable for high-temperature flue gas, desulfurization and denitrification waste gas, hot air and other media, and solves the pain points of large thrust of metal expansion joint blind plates and poor resistance to acid and alkali flue gas corrosion. It is a commonly used flexible compensation component in smoke and air pipelines.

Structural Composition
1. Flexible composite skin: The core compensation component is made of multi-layer high-temperature resistant fiberglass fabric composite silicone rubber material, which has flexible deformation, sealing, temperature resistance and anti-corrosion properties, achieving pipeline displacement compensation.

2. Internal guide tube: Red brown steel guide structure with medium flow direction identification, blocking direct erosion of the skin by high-temperature medium, buffering airflow, reducing dust wear, and extending the service life of the skin.

3. Rectangular carbon steel flange: A green anti-corrosion painted square flange with evenly spaced bolt holes on the flange surface, which is installed in conjunction with the on-site rectangular air duct flange bolts.

4. Pressure plate and rivet assembly: Rivets around the edges of the skin are tightened to ensure a tight seal between the skin and flange connection, preventing smoke leakage.

5. Limit rod assembly: consisting of screws, nuts, and supports, it limits the maximum tension and compression stroke of the compensator, protects the skin from excessive pulling and damage, and does not withstand the pressure and thrust of the pipeline medium.

6. Interlayer insulation layer: The skin interlayer is equipped with high-temperature resistant insulation filler to reduce heat loss in the pipeline and lower the temperature of the outer wall of the equipment.

Product Features
1. Multi directional comprehensive compensation
It can simultaneously absorb axial, lateral, and angular displacement, with a large compensation amount, and can digest pipeline thermal deformation and positional deviation caused by on-site installation.

2. No blind plate thrust
Non metallic flexible structure, which does not generate the huge internal pressure blind plate thrust of metal corrugated pipes, simplifies pipeline support design, and reduces support engineering costs.

3. Vibration and noise reduction
Flexible skin can block the transmission of vibration from fans and boiler equipment to pipelines, weakening the vibration and noise of the air duct system.

4. Temperature and corrosion resistance
Different skin materials can be selected according to the working conditions, suitable for -40 ℃~850 ℃ working conditions, resistant to corrosion from sulfides and acid-base media in flue gas, and suitable for harsh exhaust gas environments such as desulfurization and denitrification.

5. Excellent sealing performance
The skin compression structure is tight, effectively preventing smoke and hot air from leaking outwards; The overall weight is relatively light, reducing the load on the air duct structure.

6. Easy installation and maintenance
Flange bolt connection, easy to disassemble and assemble on site; The skin components can be replaced separately in the later stage, without the need to replace the equipment as a whole.

7. Non-standard customization
The length and width dimensions of the rectangle can be customized according to needs, suitable for various non-standard rectangular flue and air ducts.
