Preguntas frecuentes

How should Hastelloy B2 Flanges be handled and stored?

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.

Can Hastelloy B2 Flanges be welded?

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).

Are there any limitations of Hastelloy B2 Flanges?

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.

¿Existen consideraciones especiales para el mantenimiento de las bridas 254 SMO?

Se recomienda la inspección y el mantenimiento regulares para garantizar que las bridas se mantengan libres de daños y corrosión, especialmente en entornos altamente corrosivos. También es importante seguir las mejores prácticas de instalación y manipulación para evitar tensiones mecánicas y daños.
