DINKONDA GLOBAL Power Plants Special Square And Rectangular Air Duct Specialized Corrugated Compensation Element Axial/angular Displacement Rectangular Expansion Joint Compensator

Product Overview
This rectangular compensator is produced by Yanshan Shuntong Pipeline Manufacturing Co., Ltd. It is a specialized corrugated compensation component for rectangular air ducts. It is mainly used for square and rectangular smoke and air pipelines, absorbing axial, small lateral, and angular displacements caused by pipeline thermal expansion and contraction, releasing pipeline thermal stress, and reducing the risk of stress damage at equipment interfaces and duct weld positions. It is widely used in large section rectangular air ducts of power plants, metallurgy, and dust removal systems, and is suitable for medium conditions such as high-temperature flue gas, hot air, and dusty gases.

Structural Composition
The product mainly consists of a rectangular corrugated body, a rectangular flange frame, a guide lining plate, a reinforced pressure plate, and a bolt hole flange frame.
1. Rectangular corrugated body: the core flexible component is formed by pressing and welding stainless steel plates, relying on corrugated deformation to achieve displacement compensation, and has high temperature resistance and fatigue resistance characteristics;

2. Rectangular flange frame: steel plate welding processing, evenly opening bolt holes, used for docking and installation with on-site rectangular air duct flanges;

3. Guiding lining plate: Built in guiding structure, reducing the erosion and wear of high-speed dusty airflow on ripples, and minimizing the impact of eddy currents;

4. Strengthening the pressure plate: Reinforce the root of the corrugation to enhance overall rigidity and prevent local deformation of the corrugation under pressure.

Core Features
1. Suitable for square and rectangular air ducts, designed for large cross-section non-circular smoke and air ducts, capable of absorbing axial displacement and compatible with a small amount of lateral and angular comprehensive displacement.
The corrugated body is made of stainless steel material, and the flange frame is made of carbon steel, which balances temperature resistance, corrosion resistance, and structural strength, making it suitable for high-temperature dusty flue gas conditions.

2. The flange is perforated as a whole, and on-site bolt docking and installation are convenient, without the need for on-site welding, making disassembly and maintenance easy.

3. The guide lining plate effectively resists the erosion of dust particles, reduces ripple wear, and extends the service life of the equipment.

4. It can reduce air duct vibration, block the transmission of vibration to equipment such as fans and dust collectors, and reduce system operating noise.

5. The overall structure is compact, and the cross-sectional specifications and number of ripples can be customized according to the size of the air duct to match different compensation requirements.
