DINKONDA GLOBAL Power Plants Special High Performance Composite Skin Non-metallic Compensator Expansion Joint, Power Plant Air Ducts Compensation Component 

Product Overview
Non metallic skin compensator is a specialized air duct compensation component composed of high-performance composite skin as the flexible main body, combined with metal frame, flange, and limit rod. It is commonly used in hot air, flue gas, and dust removal air duct systems in power plants, metallurgy, and chemical industries. By relying on the flexible deformation of non-metallic skin, it absorbs the axial, lateral, and angular comprehensive displacement generated by the air duct, releases the thermal stress of the pipeline, and has the functions of vibration reduction, noise reduction, and seismic isolation. It can solve the problems of high temperature corrosion and limited compensation of metal expansion joints, and is a key component of large smoke and air pipelines.

Structural Composition
1. Non metallic skin: multi-layer composite structure, with an outer layer of temperature resistant and anti-corrosion silicone rubber/fluororubber coated fiberglass cloth, a middle insulation layer, and an inner layer of temperature resistant and anti-corrosion layer; Orange in the figure refers to silicone rubber composite skin, which is resistant to temperature and aging and directly contacts with smoke medium.

2. Metal frame flange: Carbon steel welded rectangular frame, with bolt holes around it, used to connect and press the skin tightly with the flue flange, and fix the seal.

3. Limit rod component: an external metal rod that bears the system pressure thrust, limits the maximum deformation, and prevents the skin from being damaged by pressure bulging or excessive stretching.

4. Tighten the pressure strip and bolt fasteners evenly along the flange, press the edge of the skin tightly to ensure interface sealing and prevent smoke leakage.

Core Features
1. Strong compensation capability, able to simultaneously absorb multi-dimensional comprehensive displacement in axial, lateral, and angular directions, with strong adaptability to pipeline installation misalignment, and can achieve greater compensation compared to metal expansion joints.

2. Resistant to high temperature and smoke corrosion, the skin can be selected with materials such as silicone rubber and fluororubber according to the working conditions. It can withstand high temperature smoke, sulfur-containing and dusty exhaust gases, resist smoke corrosion, and avoid high-temperature corrosion and failure of metal parts.

3. Vibration reduction and noise reduction can block the transmission of vibration from fans and boiler equipment to the air duct, reduce system noise, and alleviate equipment vibration fatigue.

4. Excellent sealing performance, overall flexible sealing, adaptable to slight flange deformation, effectively reducing flue air leakage rate; The overall weight is light, and compared to metal compensators, it has a smaller load on pipeline supports.

5. Easy disassembly and maintenance, the skin is a replaceable component, and can be replaced separately if damaged later, without the need to replace the entire equipment, reducing operation and maintenance costs.

6. Flexible customization of specifications, rectangular, square, and circular can be produced, and the size and temperature resistance level can be customized according to the on-site working conditions of the flue.
