Monel 400 alloy (UNS N04400 or MCu-28-1.5-1.8 or Ni68Cu28Fe) is a nickel-based alloy material with good corrosion resistance in seawater, chemical solvents, ammonia sulfur chloride, hydrogen chloride, various acidic media such as sulfuric acid, hydrofluoric acid, hydrochloric acid, phosphoric acid, organic acid, alkaline media, salt and molten salt. Monel 400 alloy also has good mechanical properties, from low temperature to high temperature wide range of use temperature, with good welding performance and medium and high strength.
Socket welding flange refers to the flange that the pipe end is inserted into the flange ring step and welded at the pipe end and the outside. There are two types: with neck and without neck. The neck pipe flange has good rigidity, small welding deformation, good sealing, and can be used in occasions with a pressure of 1.0~10.0MPa. The type B flange for containers is also a socket welding flange, which is used in occasions with high sealing requirements. When designing, the socket welding flange can be checked as an integral flange.
