About Reactors or Agitators
Reactors or Agitators
Reaction vessels or reactors, with or without agitators, with total internal (geometric) volume greater than 0.1 m³ (100 l) and less than 20 m³ (20000 l), where all surfaces that come in direct contact with the chemical(s) being processed or contained are made from the following materials:
- nickel or alloys with more than 40% nickel by weight;
- alloys with more than 25% nickel and 20% chromium by weight;
- fluoropolymers;
- glass or glass-lined (including vitrified or enamelled coating);
- tantalum or tantalum alloys;
- titanium or titanium alloys; or
- zirconium or zirconium alloys.
Agitators for use in the above-mentioned reaction vessels or reactors; and impellers, blades or shafts designed for such agitators, where all surfaces of the agitator or component that come in direct contact with the chemical(s) being processed or contained are made from the following materials:
- nickel or alloys with more than 40% nickel by weight;
- alloys with more than 25% nickel and 20% chromium by weight;
- fluoropolymers;
- glass or glass-lined (including vitrified or enamelled coating);
- tantalum or tantalum alloys;
- titanium or titanium alloys; or
