Product Description

Designated as UNS N06035 or DIN 2.4643, Alloy G-35 is a nickel-chrimium-molybdenum alloy designed to resist “wet process” phosphoric acid, which is used in the production of fertilizers. Similar to Hastelloy G-30, G35 alloy also has excellent resistance to localized attack in the presence of chlorides, since this can be a problem beneath deposits in evaporators used to concentrate “wet process” phosphoric acid. Besides, it is much less susceptible to chloride-induced stress corrosion cracking than the stainless steels and nickel-chromium-iron alloys traditionally used in “wet process” phosphoric acid. Due to the high chromium content, Hastelloy G-35 is high to other oxidizing acids, such as nitric, and mixtures containing nitric acid. It possesses moderate resistance to reducing acids, as a result of its appreciable molybdenum content, and, unlike other Ni-Cr-Mo alloys, it is very resistant to “caustic de-alloying” in hot sodium hydroxide.

The threaded olet is also called the saddle seat, and saddle type pipe joint. It is mainly used for reinforcing pipe fittings of branch pipe connection, instead of using reducing tee, reinforcing plate, reinforcing pipe section and other branch pipe connection types. It has the advantages of safety and reliability, reducing cost, simple construction, improving medium flow channel, series standardization, convenient design and selection, etc., especially in high pressure, high temperature, large diameter, thick wall pipes are used increasingly widely, replacing the traditional branch pipe connection method.
