It is also commonly used as furniture and kitchen utensils. Stainless steel pipe fittings have good mechanical properties and corrosion resistance, and are widely used in aerospace, ocean, nuclear energy, medical equipment, petrochemical and other fields. Aluminum tubes have good corrosion resistance and are mainly used in fluid delivery pipelines for high-end products. In recent years, with the development and innovation of technology, people's demand for stainless steel pipe fittings has been increasing, and their quality requirements have been continuously improved.
