Casting Flange FAQ Section
Q: What are the advantages of casting flanges over forged flanges?
A: Casting flanges offer several advantages including cost-effectiveness for large-size components, the ability to create complex geometries in a single piece, and suitability for low to medium pressure applications. The casting process allows for mass production of identical parts with consistent quality, making them ideal for projects requiring numerous identical components.
Q: How do I select the right material grade for my casting flange application?
A: Material selection depends on several factors: consider the media being transported (corrosive, abrasive, etc.), operating temperature and pressure conditions, environmental factors, and budget constraints. Carbon steel (A105) is common for general applications, stainless steel (304/316) for corrosive environments, and alloy steels for high-temperature service. Our engineers can help you determine the optimal material for your specific requirements.
Q: What quality certifications do your casting flanges carry?
A: Our casting flanges comply with multiple international standards including ISO 9001, PED 2014/68/EU, API 6A, and ASME B16.5/B16.47. Each batch undergoes rigorous testing including dimensional checks, material composition analysis, mechanical property testing, hardness tests, and non-destructive examination (NDE) including radiographic, ultrasonic, or liquid penetrant inspection as required.
