Import 254smo S31254 Stud End — Buy in wholesale FOB from Supplier in China

The 254SMO S31254 stud end from Zhengzhou Huitong Pipe Fittings is a threaded pipe fitting designed for high-integrity connections in corrosive environments, particularly where weld neck flanges are not feasible. Stud ends are typically used in high-pressure systems, allowing for easy assembly and disassembly with threaded flanges or other components. This fitting is manufactured in sizes from 1/2 inch to 24 inches (seamless) and 4 inches to 78 inches (welded), adhering to ASME B16.9, JIS, DIN, EN, and ISO standards.

Made from UNS S31254 (254SMO), the stud end offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking due to its high chromium (20%), molybdenum (6%), and nitrogen (0.2%) content. This alloy is standard for applications in chemical processing, offshore oil and gas, and desalination, where standard stainless steels like 316L are inadequate. The fitting’s threaded ends are machined to precise tolerances, with typical thread types including NPT, BSPT, or metric threads, depending on the application.

Industrial buyers in sectors such as petroleum, chemical, and marine engineering use stud ends for systems requiring frequent maintenance or modifications, as they eliminate the need for welding. The fitting is compatible with a range of materials, including carbon steel, stainless steel, and nickel alloys, though the 254SMO grade is specified here for its superior corrosion resistance. Buyers should confirm thread specifications, pressure ratings, and material test certificates to ensure compatibility with their systems.

Zhengzhou Huitong Pipe Fittings is based in Room 2004, Expo Center, Dongfeng Road, Zhengzhou, Henan Province, China, and specializes in the production of pipe fittings for industrial applications.
