Aerospace Grade Stainless Steel Pipes SUS329J1/254SMO/F44/S31254 Professional Manufacturer for Aerospace Hydraulic Tubing

Product Overview

Our Aerospace Grade Stainless Steel Pipes, including SUS329J1, 254SMO, F44, and S31254, are specifically designed for aerospace hydraulic tubing applications. These pipes are the result of advanced manufacturing techniques and strict quality control, meeting the high - standards required in the aerospace industry.

Material and Surface Treatment

• Material Composition: The SUS329J1, 254SMO, F44, and S31254 stainless steel grades used in these pipes offer exceptional corrosion resistance, high strength, and excellent mechanical properties. For example, 254SMO is a high - alloy austenitic stainless steel with a high content of chromium, molybdenum, and nitrogen, which provides outstanding resistance to pitting and crevice corrosion in aggressive environments.
• Surface Treatment: The pipes undergo a polished surface treatment. This not only gives them an aesthetically pleasing appearance but also enhances their corrosion resistance. The smooth surface reduces the risk of debris accumulation and makes the pipes easier to clean, which is crucial in aerospace applications where cleanliness is of utmost importance.

Manufacturing Technique

• Hot Rolled Process: These pipes are manufactured using the hot - rolled technique. Hot rolling involves heating the steel above its recrystallization temperature and then passing it through rollers to achieve the desired shape and dimensions. This process improves the mechanical properties of the steel, such as its ductility and toughness. It also ensures a more uniform grain structure, which is essential for the reliable performance of the pipes in aerospace hydraulic systems.

Shape and Standard

• Shape: The pipes are round in shape, which is the most common and practical shape for hydraulic tubing. The round shape provides uniform stress distribution, allowing the pipes to withstand high - pressure hydraulic fluids without deformation.
• Standard: They comply with the ASTM standard. ASTM standards are widely recognized and respected in the global market, ensuring that our pipes meet the strict quality and performance requirements set by the industry. This compliance also makes it easier for our international customers to integrate our pipes into their existing aerospace systems.

Applications in Aerospace Hydraulic Systems

• Hydraulic Fluid Conveyance: These pipes are primarily used for conveying hydraulic fluids in aerospace hydraulic systems. They can handle high - pressure fluids, ensuring the smooth and efficient operation of various hydraulic components such as actuators, valves, and pumps.
• Reliability and Safety: In aerospace applications, reliability and safety are non - negotiable. Our pipes are designed to withstand the harsh conditions of flight, including extreme temperatures, vibrations, and pressure fluctuations. Their high - strength and corrosion - resistant properties ensure long - term performance and reduce the risk of system failures, which is crucial for the safety of aircraft and their passengers.
