Technical Specifications
The ASME B16.28 standard governs the dimensions, tolerances, and mechanical properties of wrought steel buttwelding short-radius elbows. The 90° SR Elbow in this case has a Butt Welded construction. This connection method involves welding the elbow directly to the adjoining pipe, ensuring a smooth transition that minimizes the risk of leakage, enhances the flow of media through the system, and reduces the need for additional fittings. The seamless (SMLS) design further enhances the integrity of the fitting by eliminating any potential weaknesses caused by welded joints, making it suitable for high-pressure and high-stress environments.
Material Advantages: ASTM A815 UNS S32760
The super duplex stainless steel ASTM A815 UNS S32760 is the material of choice for this fitting due to its outstanding mechanical and chemical properties. Super duplex steel offers a unique combination of ferritic and austenitic structures, which delivers enhanced performance in demanding applications.
Corrosion Resistance: UNS S32760 is particularly renowned for its excellent resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. These properties make it ideal for aggressive environments, such as offshore oil and gas, chemical processing, and marine applications, where exposure to saltwater and harsh chemicals is common.
High Strength: With its high tensile strength and yield strength, this super duplex alloy provides durability and reliability under high pressure and extreme temperatures. This makes it suitable for applications requiring both structural integrity and resistance to mechanical stress.
Temperature Range: The material maintains its corrosion resistance and strength even in elevated temperatures, up to 300°C, and can perform well in cryogenic conditions as well, which is crucial for many industrial processes.
In summary, the ASME B16.28 ASTM A815 UNS S32760 90° SR elbows butt welded seamless super duplex stainless steel is an advanced pipe fitting that offers exceptional performance in harsh conditions. Its seamless construction, coupled with the superior properties of super duplex stainless steel, ensures that it can withstand high pressures, resist corrosion, and provide reliable service in a variety of industrial applications. This fitting is a trusted choice for customers who require high-quality, durable piping components.
