Monel 400 Demister Pad
Monel 400 Demister Pad is corrosion resisting, such as resistant to sea water and steam at high temperatures, resistant to salt and caustic solutions. It also has high strength. Monel 400 Demister pad has low corrosion rate in flowing brackish or seawater while performing excellent resistance to stress-corrosion cracking in most freshwaters.
Monel 400 Demister pad is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. However, its high copper content, make alloy 400 can be rapidly attacked by nitric acid and ammonia systems.
Monel 400 Demister also has good adaptability to wide range of application temperature. It maintains good mechanical properties at subzero temperatures, as well as in temperatures up to 1000° F, The melting point is 2370-2460° F.
Monel 400 Demister pad are porous blankets of monel wire knitted mesh, designed and constructed for the efficient, economical removal of entrained liquid droplets from vapor streams. Mesh Pads can be fabricated in any required size and shape and may be installed in new or existing process vessels.
