Hastelloy B2 Nipple

Hastelloy B2 Concentric Swaged Nipple has excellent resistance to all temperatures and concentrations of hydrochloric acid. Additionally, Hastelloy B2 Eccentric Swaged Nipple has good stress corrosion cracking and pitting resistance as well. However, due to the presence of high molybdenum content, Alloy B2 Hexagon Nipple is expensive.

Alloy B2 Hexagon Reducing Nipple is an alloy with controlled thermal expansion and an average coefficient of expansion in the temperature range 20 Degree C – 100 Degree C. Alloy B2 One End Threaded Nipple can be easily formed using all the conventional methods, and also can be welded using the traditional welding methods. Special precautions for Alloy B2 Both End Threaded Nipple should be taken to avoid excessive heat input.
