The product is quite useful in the case of hydrochloric acid and the like, where such aggressor media cause corrosion even in acid-resistant alloys.
- Has an exceptional resistive ability towards hydrochloric acid and strong reducing agents
- Is able to retain its mechanical strength when operated under high pressure and temperature conditions
- Can be used in the weld neck, blind, and socket weld flange configurations
- Has very good metallurgical stability which makes it ideal for longer service life
- The production process is in line with the standards set by ASTM B564 and ASME B16.5
Hastelloy B2 flanges find their major application in chemical processing plants, power stations, and offshore installations that need corrosion resistance of a reliable kind. By purchasing via a specialized B2B platform, companies can get the exact dimension, pressure rating, and surface finish that they need along with the quality, test, and delivery certificates required for uninterrupted operations.
