ALLOY B2 is a corrosion-resistant, solid-solution Ni-Mo alloy.The extremely low carbon and silicon content of Alloy B2 reduces precipitation of carbides and other phases in the heataffected zone of welds and ensures adequate corrosion resistance even in the welded condition. Alloy B2 exhibits excellent corrosion resistance in aggressive reducing media such as hydrochloric acid in a wide range of temperatures and concentrations, as well as in mediumconcentrated sulphuric acid even with limited chloride contamination. It can also be used in acetic and phosphoric acids. Optimum corrosion resistance can be obtained only if the material is in the correct metallurgical condition and exibits a clean structure.ALLOY B2 is used in a wide range of applications in the chemical process industry, especially for processes involving sulphuric, hydrochloric, phosphoric and acetic acid.
Buttwelding Elbow :In the piping system, elbows are pipe fittings that change the direction of the pipeline. According to the angle, there are three most commonly used elbows: 45°, 90°, and 180°. In addition, according to the needs of the project, there are other nonnormal angle elbows such as 60°. The materials of elbows include cast iron, stainless steel, alloy steel, forgeable cast iron, carbon steel, nonferrous metals and plastics.The ways to connect with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electric fusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welded elbow, stamped elbow, push elbow, cast elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle elbow, etc.
