Application

As a raw material, capillary is widely used in chemical, petroleum, electronics, jewelry, medical, aerospace, air conditioning, medical equipment, kitchen utensils, pharmaceuticals, water supply equipment, food machinery, power generation, boilers and other fields.
Stainless steel coil tube is a versatile material that is widely used in many industrial and commercial fields. Its main uses include:
1. Industrial field. Stainless steel coils are used in chemical, mechanical, electronic, electric power, pharmaceutical, nuclear power, petrochemical and other industries, mainly as a part of heat exchangers, boilers, refrigeration systems, heating furnaces, etc., for heat transfer, condensation or fluid transport.
Fluid transport. Used for beverages, beer, milk, water supply systems, etc., for the transport of liquids or gases.
2. Construction field. Stainless steel coils are used in heating and air conditioning systems and other internal sanitary plumbing systems, making them a popular choice in the construction sector due to their corrosion resistance and ease of cleaning.
3. Energy saving. In solar energy, ground source heat pumps, energy recovery and other environmental projects, stainless steel coils are widely used because of their efficient heat transfer performance.
4. Mechanical structure. Used in printing and dyeing, printing, textile, medical equipment, kitchen equipment, automotive and Marine parts, construction and decoration, especially in the need of high temperature, corrosion resistance occasions.
5, in addition, the characteristics of stainless steel coil include high-temperature steam resistance, impact corrosion resistance, ammonia corrosion resistance, scaling resistance, etc., so that it performs well in long-term use, its long service life and reduce the need for maintenance and maintenance, thus saving costs.
