When using forged flanges, it is important to pay attention to several key aspects to ensure that the flanges operate properly and have the expected service life. The following are the precautions for using forged flanges and a practical production case:
- Selecting suitable materials and specifications
Using the correct materials and specifications is critical to ensuring the proper operation of the flange. Choosing inappropriate materials or specifications may cause the flange to fail under load or create safety hazards. Therefore, before selecting forged flanges, the working conditions and requirements must be evaluated in detail, and the selected flanges must meet relevant standards and specifications.
- Checking flange structure and surface
When using forged flanges, it is necessary to carefully examine the quality of their structure and surface. If there are deep scratches, cracks, or other defects on the surface, this can reduce the strength and sealing performance of the flange. Before using the flange, it must be cleaned or treated to ensure its overall quality and performance.
- Using the correct fasteners
Choosing appropriate fasteners such as transient plugs and gaskets can improve the sealing and strength of the flange and prevent problems such as looseness and leakage. When using forged flanges, it is necessary to select and install the appropriate fasteners and perform appropriate pre-tightening adjustments.
- Technical operation specifications
Before using forged flanges, it is necessary to understand their usage conditions and environment. Users must comply with relevant safety operation specifications, including using proper operating devices, oil injection, and maintenance measures, to ensure that the flanges operate properly and to extend their service life.
- Practical production case
An airline company needs to use super alloy materials (high temperature, corrosion resistance, etc.) to forge a batch of new engine flanges for installation on wide-body aircraft. For this plan, they determined that multiple welding, cold working, and heat treatment processes were required, so they chose forged flanges. To ensure quality, they also established a QMS (Quality Management System) that makes adjustments and improvements to the manufacturing process when QMS anomalies occur. After sales, the flange can support mechanical strength and sealing performance under heavy loads and high pressures.
In conclusion, it is important to pay attention to these key issues when using forged flanges to ensure that the flanges operate properly and have long-term service life while meeting the expected reliability and performance.
