FAQ (Frequently Asked Questions)

Are Incoloy 825 Flanges suitable for cryogenic applications?

Incoloy 825 flanges are generally not recommended for cryogenic applications due to potential embrittlement and reduced toughness at low temperatures. They may experience decreased ductility and susceptibility to cracking, compromising their performance and reliability in cryogenic environments. Alternative materials with better cryogenic properties are preferred for such applications.

How do I ensure the reliability of Incoloy 825 Flanges suppliers?

To ensure reliability, assess Incoloy 825 flange suppliers based on factors such as reputation, certifications (ISO, ASME), product quality, adherence to industry standards, delivery capabilities, and customer reviews. Conduct audits, request samples, and establish clear communication channels to verify their commitment to consistency and reliability in product supply.

Can Incoloy 825 Flanges be used for potable water applications?

Incoloy 825 flanges are typically used in corrosive environments, but they may not be suitable for potable water applications due to potential leaching of nickel and other alloying elements, which could exceed regulatory limits. Stainless steel or other materials specifically certified for potable water are preferred for such applications.
