FAQ
Storage: Should be stored in a dry, clean area to prevent contamination.
Handling: Use appropriate handling equipment to avoid scratches, dents, or any surface damage that could compromise corrosion resistance.
Yes, Hastelloy B2 flanges can be welded using standard welding methods, but care must be taken to minimize heat input and avoid carbide precipitation, which could lead to intergranular corrosion. Common welding methods include TIG (GTAW) and MIG (GMAW).
Oxidizing Environments: Hastelloy B2 is less effective in fully oxidizing environments or where oxidizing contaminants are present.
Cost: Hastelloy B2 flanges are relatively expensive due to the high cost of raw materials and manufacturing processes.
Regular inspection and maintenance are recommended to ensure the flanges remain free from damage and corrosion, especially in highly corrosive environments. It is also important to follow best practices for installation and handling to avoid mechanical stresses and damage.
Summary
The Hastelloy B2 flanges we offer are suitable for use in chemical, petrochemical, pharmaceutical, and energy production fields, particularly in situations where strong acids, corrosive chemicals, or harsh environments need to be managed.
