A. Heat exchangers and piping in crude oil desalination units.
B. Catalytic Cracking Unit. Catalytic absorption and desorption tower lining, tray plate, tube, etc., gasoline reheater.
C. Hydrocracking unit. Air cooler, desulfurization reactor, heat exchanger of water cooler.
2. Petrochemical industry (neutral chloride)
A. Polyvinyl Chloride (PVC) Stripper and Heat Exchanger.
b. Coil oxychlorination reactor and vinyl chloride reboiler in vinyl chloride plant.
c. Catalyst tube bundles, feed/effluent heat exchangers, medium pressure flash tank top condensers for methanol synthesis reactors.
D. Oxo alcohol pipeline loop reactor.
E. Production equipment and pipelines of organic acids (formaldehyde, formic acid) such as acetic acid.
3. Onshore and Offshore Oil and Gas Industry (Sour Oil Well Tubulars and Pipelines)
A. Delivery pipes and gas collectors.
b. Heat exchangers, water treatment and water supply systems for offshore oil platforms, fire protection systems, water spray systems, and water stabilization systems.
4. Pulp and Paper Industry
A. Continuous sulfuric acid cooking or batch cooking units. Such as: sawdust preheater, digester, condenser, etc.
5. fertilizer industry
A. Urea industry. CO2 compressor cooler line. Methyl ammonium pump body. The stripping pipe of the stripping tower, the condensing pipe of the high-pressure condenser, the decomposition pipe and the conveying pipeline of the high-pressure decomposition tower.
b. Phosphate fertilizer industry. Reaction tank, slurry circulation and slurry transportation pipeline.
6. high-strength structural parts
The tensioning system of the drilling frame on the platform and the submarine pipeline are adopted. Steam passes through flat blades, barges, tankers, etc.
