In the production process of spandex, the specific application scenarios of titanium fittings mainly include the following aspects:

1. Aggregation reactor: The production of spandex begins with polymerization reaction, which is usually carried out at high temperature and pressure. Titanium fittings can be used as internal components of polymerization reactors, such as pipes, flanges, valves, etc., because they can withstand high temperatures and corrosive media inside the reactor.

2. Heat exchanger: During the polymerization reaction and subsequent processing, it is necessary to control the temperature through a heat exchanger. Titanium fittings are highly suitable as components for heat exchangers due to their excellent heat resistance and corrosion resistance.

3. Transportation pipeline: At different stages of spandex production, various chemical substances need to be transported, including monomers, polymerization agents, solvents, etc. Titanium fittings are suitable for transporting these chemicals in pipelines due to their corrosion resistance and temperature resistance.

4. Spinning component: During the spinning process, spandex solution is squeezed through tiny pores to form silk threads. Titanium fittings can be used to manufacture these spinning components due to their smooth surface and resistance to contamination, which helps maintain the quality and uniformity of the threads.

5. Filtration system: In spandex production, the filtration system is used to remove impurities from the solution. Titanium fittings can be used for pipelines and connectors in filtration systems, and due to their corrosion resistance, they will not react with the filtration medium.

6. Storage and transportation containers: Chemical substances used in the production process of spandex need to be stored and transported, and titanium fittings can be used as connecting components for these containers to ensure the stability and safety of the medium during storage and transportation.

7. Recycling system: During the production process, there may be waste liquid or unreacted monomers that need to be recycled. Titanium fittings are suitable for pipelines in these recycling systems and can work stably in harsh chemical environments.

The application of titanium fittings in spandex production is not limited to the above scenarios. Their use can run through the entire production process, from raw material preparation to the formation of the final product, playing an important role.
