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 pipe bend is made by using a complete set of bending equipment, which is divided into two processes: cold bending and hot pushing. Regardless of the type of machine equipment and pipeline, most of them use pipe bends, which are mainly used for oil, gas, liquid infusion, engineering bridge construction, etc. According to its curvature radius: it can be divided into long radius elbows and short radius elbows. Long radius elbows refer to elbows whose curvature radius is equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D; short radius elbows refer to elbows whose curvature radius is equal to the outer diameter of the pipe, that is, R=1.0D.
