Stainless steel hardware is particularly crucial in the aerospace and petroleum industries, as it must withstand extreme environments and high-precision requirements. This is primarily reflected in the following areas:

Precision connections and protection in the aerospace sector: Stainless steel fittings, valves, and other accessories are core connectors in spacecraft fuel delivery systems and hydraulic control systems. They must withstand the intense vibrations of rocket launches, extreme temperature fluctuations (-200°C to over 500°C), and the vacuum environment of space. Their high strength, fatigue resistance, and excellent sealing properties prevent the leakage of media such as fuel and hydraulic oil, ensuring the stable operation of spacecraft propulsion systems and attitude control systems. Furthermore, stainless steel screws and flanges provide lightweight and secure connections in spacecraft structural assembly, while protecting against cosmic rays and space particles, maintaining the structural integrity of the equipment.

Corrosion-resistant and pressure-resistant support for oil extraction and transportation: Stainless steel pipe fittings, fittings, valves, and other accessories are widely used in oil drilling platforms and pipeline systems. The crude oil and natural gas involved in oil extraction often contain corrosive media such as hydrogen sulfide and chloride ions, and the transmission pressures are extremely high (reaching tens of megapascals). The corrosion resistance and pressure resistance of stainless steel (such as 316) play a crucial role in this process, effectively resisting media erosion and high-pressure shock, reducing risks such as pipeline leaks and fitting damage. In deep-sea oil extraction equipment, stainless steel hardware must also withstand the intense corrosion of seawater and the high pressures of the deep sea to ensure the long-term stable operation of equipment such as underwater Christmas trees and oil pipelines.

Safety and cleanliness in the refining process: The oil refining process involves reactions and transmission of high temperatures, high pressures, and a variety of chemical solvents. Stainless steel flanges, compression fittings, and other fittings are used to connect equipment such as reactors, heat exchangers, and pipelines. Their smooth interior and chemical resistance prevent contamination from the media, while their sealing properties prevent leakage of flammable, explosive, and toxic media, minimizing safety risks. Furthermore, the easy-to-clean nature of stainless steel fittings meets the refining industry's stringent requirements for equipment hygiene and process precision, ensuring the quality of refined products.
