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.
Blind flange is a type of flange connection, which is actually a flange without a hole in the middle. One of its functions is to block the end of the pipe, and the other is to facilitate the removal of debris in the pipe during maintenance. In terms of blocking, it has the same function as the head and the pipe cap. However, the head cannot be disassembled, while the blind flange is fixed with bolts and is very easy to disassemble. The materials of the blind flange include carbon steel, alloy steel, stainless steel, plastic, etc.
