Direct Conclusion
Under ultra-high temperature conditions, Airuisen anti-seize compound can be selected to prevent screw seizure. Apply it to the threaded surface to form a lubricating protective layer, avoiding thread bonding and seizure at high temperatures; if the working condition is special, confirm the suitable product with the purchasing consultant based on the condition.
Application Pain Points
In industrial high-temperature environments, screws are prone to seizure due to thermal expansion causing thread clearance disappearance, oxide layer bonding, and lubricant failure. This not only increases disassembly difficulty but may also damage components and affect equipment operation and maintenance efficiency.
Applicable Working Conditions
This solution is applicable to scenarios such as industrial machinery, chemical reactors, high-temperature pipelines, metallurgical equipment, etc. The temperature of corresponding threaded connection parts is usually above 200℃, and some working conditions can reach 500℃-800℃, with continuous high temperature or temperature fluctuations.
Adhesive Selection Guidelines
Priority should be given to anti-seize products with high temperature resistance, oxidation resistance, and stable lubricity, to avoid failure of ordinary thread locking agents due to high-temperature decomposition. It is necessary to match the working condition temperature, load type, and screw material to ensure the product maintains protective performance at high temperatures.
Key Parameter Table
| Product Type | Applicable Temperature Range | Core Performance |
|---|---|---|
| Airuisen Anti-Seize Compound | 200℃-800℃ | Anti-seize, oxidation resistance, long-lasting lubrication |
| Confirm with purchasing consultant based on working conditions | Customized matching | Suitable for special high-temperature corrosion working conditions |
Construction and Testing Suggestions
Before construction, clean the screw threads and contact surfaces with Airuisen cleaner to remove oil stains and rust; apply the anti-seize compound evenly, controlling the thickness at 0.1-0.2mm to avoid thread sticking caused by excessive amount; tighten according to the standard torque during installation to avoid excessive tightening that aggravates seizure.
During testing, try to disassemble after the equipment runs for 100 hours, check if there are bonding traces on the threads. If seizure occurs, adjust the product model or application amount, and consult a technical consultant if necessary.
Purchasing Communication Checklist
- Provide the maximum temperature and duration of the working environment
- Specify the screw material, specifications and load type
- Inform if there are additional factors such as corrosive media, vibration, etc.
- Confirm if supporting cleaner/accelerator pretreatment is required
Frequently Asked Questions
What are the main causes of screw seizure under ultra-high temperature?
It is mainly due to thermal expansion causing thread clearance disappearance, oxide layer formation on metal surfaces leading to bonding, and original lubricant decomposition and failure at high temperatures—these three factors together cause seizure.
Can anti-seize compound replace thread locking agent?
Anti-seize compound focuses on anti-seize and lubrication, while thread locking agent focuses on anti-loosening. Their functions are different, so they can be used in combination according to needs, no need to replace.
How to select products for special high-temperature working conditions?
You can confirm with Airuisen purchasing consultant based on working conditions. After providing detailed working condition parameters, you can get customized product recommendations and application suggestions.
