DINKONDA GLOBAL Power Plants Special Circular Non-metallic High-temperature Resistant Composite Skin Compensator Expansion Joint, Circular Air Duct Flexible Compensation Element

Product Overview
The circular non-metallic skin compensator is a flexible compensation component specifically designed for circular air ducts, consisting of high-temperature resistant composite skin, circular flange, limit rod, and compression fastener. Mainly used in circular smoke, hot air, and dust removal pipeline systems, relying on the flexible deformation of non-metallic skin to absorb the axial, lateral, and angular comprehensive displacement generated during pipeline operation, release thermal expansion stress, and have the functions of vibration reduction, noise reduction, and smoke corrosion resistance. It is widely used in circular ventilation and smoke exhaust pipelines such as thermal power, metallurgy, chemical engineering, and kilns.

Structural Composition
1. Non metallic skin: multi-layer composite structure, the main body is silicone rubber coated with glass fiber cloth, which can be added with thermal insulation layer. The red skin is temperature resistant and anti-aging, directly contacting with flue gas media, to achieve flexible deformation.

2. Circular flange: Carbon steel circular flange with evenly spaced bolt holes, used for docking with pipeline flanges, tightening and fixing the skin to ensure assembly strength.

3. Limit rod component: an external metal limit rod that can withstand the pressure and thrust of the pipeline medium, limit the maximum expansion and contraction displacement of the compensator, and prevent skin swelling, tearing, and damage.

4. Pressure strips and fastening bolts: evenly arranged along the circumference of the flange, tightly pressing the edge of the skin to prevent smoke leakage and ensure overall sealing performance.

Core Features
1. Strong multi-dimensional displacement compensation capability, capable of simultaneously absorbing axial expansion, lateral offset, and angular deflection, with good adaptability to pipeline installation alignment errors, and overall compensation superior to metal circular expansion joints.

2. Temperature resistant and corrosion-resistant, the skin can be made of silicone rubber or fluororubber materials according to the working conditions, suitable for high temperature flue gas, sulfur-containing and dusty exhaust gas, resistant to flue gas corrosion, and not easy to rust and fail.

3. Vibration reduction and noise reduction effectively block the transmission of vibration from fans and boiler equipment to pipelines, reducing system vibration fatigue and operational noise.

4. Light weight, low support load, significantly reduced weight compared to metal expansion joints, reducing the load-bearing capacity of pipeline supports and hangers.

5. Low maintenance cost, the skin is an independent vulnerable part, and in case of damage, the skin can be replaced separately without the need to replace the entire equipment.

6. The specifications can be customized, and the diameter, length, and temperature resistance level can be customized according to needs, suitable for various circular ventilation and smoke exhaust pipes.
