Import Astm A182 F51 Threadolet — Buy in Bulk from Supplier in China

The ASTM A182 F51 Threadolet is a forged branch connection fitting made from duplex stainless steel, designed for high-pressure piping systems where corrosion resistance and strength are critical. This specific threadolet conforms to ASTM A182 F51, a grade of duplex stainless steel containing approximately 22% chromium and 5% nickel, offering excellent resistance to stress corrosion cracking and pitting in chloride-rich environments. It is typically used in sizes ranging from 1/2" to 24", with threaded ends for easy installation in pipelines requiring frequent disassembly or maintenance.

Duplex stainless steels like F51 combine austenitic and ferritic microstructures, providing higher tensile strength and impact resistance than standard austenitic grades while maintaining good weldability. The threadolet is produced in compliance with ASME B16.11 for socket welding and threaded fittings, ensuring dimensional accuracy and pressure integrity. Surface finishes are typically pickled to remove scale and contaminants, meeting industry standards for cleanliness in oil and gas, chemical processing, and marine applications.

These fittings are sourced by EPC contractors and pipeline fabricators who require reliable performance in aggressive media such as seawater, acids, or alkaline solutions. The supplier packages these components in plywood cases or wooden boxes to prevent damage during transit, with exports documented to the United States, Germany, Saudi Arabia, and South Korea. Buyers are advised to confirm thread types (NPT, BSPT) and pressure ratings (Class 3000, 6000, or 9000) to match their system requirements, as these can vary by application.
