DINKONDA GLOBAL Power Plants Special Curved Tube Pressure Balance Corrugated Expansion Joint Compensator, Pipeline Systems Specialized Flexible Compensation Element

Product Overview
This curved pressure balanced corrugated expansion joint is produced by DINKONDA GLOBAL and is a specialized flexible compensation component for pipeline systems. It is mainly used to absorb thermal displacement of pipelines and can also balance the thrust generated by the internal pressure of corrugated pipes, reducing the load on pipe racks and equipment interfaces. The product is suitable for pipeline conditions with lateral branch pipes and is widely used in gas, air, coal powder pipelines, thermal pipelines, chemical, metallurgical and other medium transportation pipelines in thermal power plants. It effectively solves displacement, vibration and other problems caused by thermal expansion and contraction.

Structural Composition
The whole machine is mainly composed of working corrugated pipes, balance corrugated pipes, curved pipes (bypass connections), pressure bearing frames, limit rods, flanges/connections, base support components, and lifting lugs.
1. Working bellows: As a core compensation component, it absorbs axial and small lateral thermal displacement generated by the pipeline, and can withstand changes in medium pressure and temperature;

2. Balanced bellows: In conjunction with the working bellows, it relies on medium pressure to achieve pressure self balance and counteract internal pressure thrust;

3. Curved pipe bypass connection: realizes medium connection, ensures medium circulation, and completes pressure balance circuit;

4. Pressure bearing frame and limit rod: bear the thrust generated by the medium pressure, limit the maximum compensation amount, prevent damage to the corrugated pipe due to excessive stretching and compression, and also bear the lifting force of the equipment;

5. Connection end structure: can be in the form of flanges or welded connections for easy connection with on-site pipelines;

6. Base support: supports the expansion joint body, reduces the additional load of the pipeline on the equipment interface, and facilitates on-site installation and positioning.

Core Features
1. Automatic pressure balancing: The curved tube pressure balancing structure can effectively counteract the huge thrust generated by the internal pressure of the pipeline, significantly reduce the design load of the fixed support, and reduce the investment cost of the support.

2. Strong displacement compensation capability: It can absorb axial displacement of pipelines and adapt to a certain amount of lateral displacement, as well as complex pipe sections such as elbows and three-way branch pipes.

3. Overall frame limit protection: equipped with limit rods and pressure bearing frames, limiting the maximum allowable deformation of corrugated pipes, avoiding over displacement damage, and improving equipment operation safety.

4. Excellent temperature and pressure resistance: The corrugated pipe is made of stainless steel material, which can adapt to high-temperature flue gas, hot air and other media, resist fatigue and corrosion, and is suitable for long-term continuous operation of power plant flues and thermal pipelines.

5. Vibration reduction and noise reduction: It can absorb pipeline vibration, weaken the transmission of vibration to equipment and pipe racks, and reduce system noise.

6. Good installation adaptability: It comes with a supporting base and lifting ears, making it easy to lift and align on site. Welding or flange connection methods can be selected as needed.
