Choosing the appropriate forged flanges is crucial to ensure the safety of pipeline connections. Consider the following areas when selecting suitable forged flanges.
- Material selection based on the medium: High-quality steel plates are typically the preferred material for manufacturing forged flanges, but in specific circumstances, one must select materials that are more corrosion-resistant or high-temperature tolerant.
- Selection based on working pressure, temperature, and medium pressure: The working pressure of pipelines varies from different operating conditions. Therefore, suitable models, specifications, and materials should be selected depending on the actual usage scenarios.
- Selection based on connector type: Forged flanges have multiple connection types such as butt-welded, threaded, and flanged connections; therefore, appropriate connector type should be selected based on design drawings and specific equipment sizing.
- Brand and quality considerations: Choose reputable large-scale manufacturers when selecting forged flanges. Avoid purchasing cheap poor quality products which may not guarantee safety.
The following are two specific production cases:
- A new project of a petrochemical company requires purchasing 1,100 forged flanges made of stainless steel and carbon steel, with the majority of the flanges connecting high-temperature and high-pressure pipelines. Due to strict safety requirements, a reputable large-scale manufacturer was chosen, and suitable production schemes were designed and screened according to actual usage requirements. ASTM A105/ASME SA105 was ultimately used for the design and manufacture of butt-welded flanges.
- A precision equipment manufacturer requires customized forged flanges to meet specific requirements. Since the product is unlike conventional processing, the manufacturing requirements for the flanges are very high, and the design drawings are also complex. Mathematical calculations and simulating assembling confirmed that the flange sizes and specifications matched related parts to ensure their compatibility and produce high-quality forged flanges.
When selecting appropriate forged flanges, one should consider multiple factors to ensure that they will operate reliably during the working process. Only by selecting suitable forged flanges can one ensure the safety and stability of the pipeline system.
