1. Classify by material type
Pure titanium reaction kettle: mainly made of TA1 and TA2 industrial pure titanium, suitable for conventional corrosive media;
Titanium alloy reactor:
TA9/TA10: Contains palladium or nickel alloys, resistant to pitting/crevice corrosion, suitable for strong acid environments;
TC4: High strength alpha+beta alloy, used in high-pressure reaction scenarios;
Composite titanium reactor: titanium material is combined with carbon steel/stainless steel to reduce costs and achieve balanced performance.
2. Classify by function and structure
Standard type reaction kettle: volume 0.1-100m ³, wall thickness 10-30mm, suitable for conventional chemical reactions;
Customized reaction kettle: Integrated stirring, heating/cooling, and sealing systems, supporting aseptic processes in the pharmaceutical and food industries.
Domestic grades: TA2, TA9, TA10, TC4.
International grades: Gr2, Gr7, Gr12, Gr5.
1. Raw material processing:
Using a vacuum consumable electric arc furnace to melt titanium ingots, with impurity content ≤ 0.1%;
2. Molding process:
Rolling welding: Titanium plate rolling welding, with weld strength ≥ 90% of the substrate;
Explosive composite: titanium layer and carbon steel composite to enhance cost-effectiveness;
3. Welding technology:
Argon arc welding or laser welding, inert gas protection to prevent weld oxidation;
4. Surface treatment:
Acid pickling passivation forms a uniform oxide film, and sandblasting treatment improves the accuracy of the sealing surface.
Corrosion resistance: Corrosion rate in 3% hydrochloric acid is less than 0.1mm/year, which is 10 times better than stainless steel;
High temperature stability: TA10 titanium alloy has a strength of ≥ 450MPa at 600 ℃ and is suitable for high-temperature catalytic reactions;
Health and safety: Complies with FDA and GMP standards, with an inner wall smoothness Ra ≤ 0.4 μ m, reducing material residue;
Lightweight and energy-saving: With the same volume, the weight of the stainless steel kettle is reduced by 40%, and energy consumption is reduced by 25%.
Chemical industry: sulfuric acid concentration, chlor alkali production, dye synthesis;
Food industry: food additives, enzymatic hydrolysis reactions;
Metallurgical industry: Metal electrolysis, surface treatment, titanium reaction kettle for electroplating solution treatment;
Energy sector: nuclear fuel reprocessing, hydrogen catalysis.
