Product Description

Product Description

 

As a key component of the connection and support structure, screws play a crucial role in ensuring the normal operation and efficient performance of steam turbines. screws are mainly used in high-temperature parts of steam turbines, such as high-temperature blades, high-temperature cylinder bodies, etc., to maintain the stability of key parts of the turbine and ensure the normal operation of the system.

The high-temperature screws used for steam turbines are made of special high-temperature alloy materials, which have excellent high-temperature strength, anti loosening, corrosion resistance, and oxidation resistance.

The commonly used special high-temperature alloys for steam turbines include 15CrMoA, 35CRMOA, 40CrMoV-5, 45Cr1MoV, 0Cr18Ni9, 1Cr11Co3W3NiMoVNbNB, 1Cr18Ni9Ti, 20Cr1Mo1VNbTiB, 20Cr1Mo1VTiB, 25Cr2MoVA, 2Cr11Mo1NiWVNbN, and 2Cr12NiMo1W.

The manufacturing of high-temperature screws requires precise process control to ensure their precise dimensions and meet high quality standards. Quality control is crucial throughout the entire manufacturing process. By using various inspection techniques such as size measurement, metallographic microscopy, ultrasonic testing, etc., ensure that each screw meets the specification requirements.

Product Features of High-temperature screws

1. It has excellent high-temperature resistance and can work stably for a long time in high-temperature environments.

2. High strength, able to withstand high pressure and high temperature force loads during turbine operation.

3. It has good anti loosening performance and can maintain stable fastening force in vibration environments.


 

Wide Application of High-temperature screws

High temperature hex nuts are widely used in various key parts of steam turbines, including the following aspects:

1. Used to fix the blades and ensure reliable connection between the blades and the rotor.
2. Used to fix the cylinder head to ensure sealing and structural stability.
3. Used to link the pipelines of various steam turbine systems to ensure the safe operation and sealing performance of the pipeline system.
4. Used for installing accessories such as pumps and valves in the steam turbine to ensure a secure connection with the turbine body.
