High Temperature Power Plant Expansion Joints Rubber Fabric Rectangular Non Metallic Bellows

DINKONDA GLOBAL Power Plants Special High Temperature Resistant Rubber Composite Fabric Skin Rectangular Non-metallic Flexible Compensator Non-metallic Expansion Joint

Product Overview
This rectangular non-metallic flexible compensator is mainly used in square air ducts and flue systems. It is assembled by combining silicone rubber composite fabric skin, rectangular steel flange, limit rod assembly, and internal guide tube. By relying on the flexible deformation of the fabric skin, it absorbs the axial, transverse, and angular thermal displacement generated by the pipeline, eliminates the thermal expansion stress of the pipeline, buffers the vibration of the fan and equipment, compensates for the installation deviation of the pipeline, and prevents the leakage of flue gas and hot air media. It is widely used in square air duct pipelines such as power plant desulfurization, boilers, cement, metallurgy, and chemical engineering.

Structural Composition
1. High temperature resistant fabric skin: silicone rubber composite glass fiber fabric is the core flexible compensation component of this product, which has high temperature resistance, aging resistance, and repeated deformation resistance; Acid alkali corrosion conditions can be replaced with fluororubber and PTFE composite skin.

2. Rectangular steel flange: Carbon steel welded rectangular flange, with evenly distributed bolt holes on the flange surface, strong structural rigidity, and easy connection with square pipeline flanges on site.

3. Limit rod assembly: Multiple sets of screws, supports, and locking nuts limit the maximum stretching stroke of the compensator, preventing the skin from being excessively stretched and torn, while also bearing some of the medium pressure thrust to protect the product.

4. Internal guide tube: Metal guide tube with medium flow direction indicator arrow, blocking direct flushing of high-temperature medium on the skin, reducing fluid flushing wear, reducing wind resistance, and extending the service life of the skin.

5. Pressure plate and fasteners: The combination of pressure strips and bolts compresses both ends of the skin to ensure a tight seal between the skin and flange interface, avoiding medium leakage.

Core Features
1. Multidimensional displacement compensation: It can simultaneously absorb axial, lateral, and angular comprehensive displacements, reduce the requirements for pipeline installation alignment, and adapt to working conditions with large thermal deformation and strong equipment vibration.

2. No significant pressure thrust: Non metallic flexible structure, compared to metal corrugated compensators, pipeline supports do not have to withstand huge medium thrust, reducing support design and manufacturing costs.

3. Vibration reduction and noise reduction: The fabric skin partitions the transmission of vibration, weakens the vibration transmitted by fans and equipment to the flue, and reduces the operating noise of pipelines.

4. Wide range of temperature resistance: Standard silicone rubber skin can adapt to high temperature smoke and hot air; Corrosion exhaust gas conditions can be upgraded with fluororubber and polytetrafluoroethylene composite skin.

5. Reliable sealing: The pressure strip bolt compression sealing structure effectively prevents the leakage of smoke and hot air.

6. Easy maintenance: flange bolt connection, convenient on-site installation; The skin is a vulnerable part that can be disassembled and replaced separately, with low maintenance costs.

7. Non standard customization: The length and width dimensions of the cross-section, compensation amount, temperature resistance, and pressure resistance can all be customized for production according to actual working conditions.
