Uncover premium alloy steel threaded and socket weld fittings compliant with ASTM A182, spanning sizes from 1/8" NB to 4" NB.

Alloy steel forged fittings, classified under ASTM A182 & ASME SA182 specifications, represent essential components in piping systems requiring robust performance under high-pressure and high-temperature conditions. These fittings are manufactured to adhere to stringent standards such as ASME B16.11, MSS SP-79, 83, 95, 97, and BS 3799, ensuring dimensional accuracy, material quality, and compatibility with various piping configurations. Available in a size range from 1/8” NB to 4” NB (DN6 ~ DN100), alloy steel forged fittings cater to a diverse range of industrial applications, offering flexibility in design and installation.

The A182 series of alloy steel grades, including F1, F5, F9, F11, F12, F22, and F91, offer varying levels of strength, corrosion resistance, and heat resistance, making them suitable for different operating environments. These grades are meticulously chosen based on specific application requirements, with F5 and F9 often preferred for low-temperature services, while F11 and F22 are commonly used in high-temperature and high-pressure applications. The versatility of alloy steel forged fittings allows engineers and designers to select the appropriate grade and class to ensure optimal performance and reliability in challenging operating conditions.

Alloy steel forged fittings are available in different classes, including 2000 LBS, 3000 LBS, 6000 LBS, and 9000 LBS, accommodating varying pressure ratings to meet the demands of specific piping systems. These fittings come in two main types: socket weld fittings and screwed-threaded fittings, providing options for different installation methods based on project requirements. With thread types such as NPT (National Pipe Thread), BSPT (British Standard Pipe Taper), and BSPP (British Standard Pipe Parallel), alloy steel forged fittings offer versatility in connecting to pipes, valves, and other components within the piping system, ensuring seamless integration and reliable performance.

01 What are A182 alloy steel forged fittings, and what distinguishes them from other types of fittings?

A182 alloy steel forged fittings are components used in piping systems, manufactured from alloy steel conforming to ASTM A182 specifications. These fittings are distinguished by their forged construction, ensuring superior strength and integrity compared to cast fittings. Available in threaded and socket weld configurations, they provide reliable connections in high-pressure and high-temperature applications.

Threaded fittings feature external threads that allow them to be screwed onto pipes or other fittings, providing a secure connection without welding. On the other hand, socket weld fittings have a socket at one end where the pipe is inserted and welded for a robust joint. Threaded fittings offer easier installation and disassembly, while socket weld fittings are preferred for applications requiring higher structural integrity.

A182 alloy steel forged fittings are manufactured in accordance with ASTM A182 specifications, ensuring material quality and dimensional accuracy. Additionally, standards such as ASME B16.11 and MSS SP-79, 83, 95, 97 provide guidelines for dimensions, ratings, materials, and testing of threaded and socket weld fittings, ensuring compliance with industry requirements.

A182 alloy steel forged fittings are available in a range of sizes, typically from 1/8” NB to 4” NB (Nominal Bore), catering to various piping requirements. These fittings are offered in different pressure ratings, including 2000 LBS, 3000 LBS, 6000 LBS, and 9000 LBS, allowing for compatibility with different operating pressures and applications.

A182 alloy steel forged fittings, whether threaded or socket weld, are suitable for a wide range of applications across industries such as oil and gas, petrochemical, chemical processing, power generation, and more. Their high strength, corrosion resistance, and versatility make them ideal for use in demanding environments where reliability and performance are paramount.
