High-pressure heater

PRODUCT DESCRIPTION:

High-pressure heaters are high-efficiency, energy-saving products that utilize steam extracted from a steam turbine to heat boiler feedwater and increase its temperature. Our company typically designs and manufactures high-pressure heaters with a U-tube structure, suitable for units of 300MW and below.

PRODUCT DETAILS

Features  

1. Structurally adaptable to varying generator parameters, ensuring safe and reliable operation. It is vibration-proof, erosion-proof, leak-proof, and features excellent self-tightening sealing performance.

2. High heat transfer efficiency, improving the heat transfer coefficient of the piping system, adapting to peak-shaving operation of the unit, and maximizing the heat transfer efficiency of the equipment's heat transfer area.

3. Easy to maintain. The equipment body is a fully welded structure, and the manhole is self-tightening and sealed, allowing for quick disassembly and convenient maintenance.

4. Advanced manufacturing technology. It employs a pre-welding and post-expansion process. Pipe joint welding uses all-position argon arc welding, and expansion joints use a liquid bag expansion method, ensuring leak-proof pipe joints.

5.The high-pressure heater manufacturing process requires strict standards and is classified as a Class A1 high-pressure vessel. The company has a complete quality assurance control system with strict process control requirements for the materials used, as well as inspection, testing, and process methods, ensuring product reliability.
