COATINGS Chemically Resistant Filter Housings for API Manufacturing Highly corrosive chemicals such as concentrated acids are often used in API manufacturing which places great demands on both filter media and filter housings. Where highly corrosive chemicals are being processed, specialised filter housings such as those manufactured with an internal coating or made from exotic nickel alloys may be considered. However, neither of these options is ideal. Coatings are prone to mechanical damage and nickel alloys have limited resistance to corrosion by certain acids and some other chemicals. Traditionally, the preferred construction materials for filter housings used in API manufacturing have been Hastelloy Steel or Titanium - unfortunately both can be very costly with long lead times for delivery.
