Product details

Advantages of stainless steel capillaries

Good corrosion resistance: stainless steel capillaries have good corrosion resistance and can work normally at quite high temperatures and various strong corrosive media for a long time, especially in the environment of chemical media, especially when working in low temperature freezing environment, stainless steel capillaries must be used.

Good bending performance: stainless steel capillary has good bending performance, and its shape can be adjusted according to needs, which is easy to meet the needs of structural space.

High strength: Stainless steel capillaries have high strength and tensile strength than traditional stainless steel pipes, which can adapt to various application requirements.

Application of stainless steel capillaries

Petrochemical, chemical industry and other processes of conveying equipment, water treatment: stainless steel capillaries can be used for drinking water treatment and other water treatment processes, automotive industry: stainless steel capillaries can be used for automotive engine refrigeration systems, fuel systems, etc., air conditioning refrigeration: stainless steel capillaries can be used for air conditioning refrigeration systems, etc. Power: Stainless steel capillaries can be used in the power industry, such as hydropower stations, thermal power stations, etc.
