THREADING & COUPLING are primarily used to achieve reliable connections between steel pipes, serving as a critical component in ensuring the efficient and safe operation of pipeline systems.
Threaded processing involves machining and cutting a spiral-shaped structure at the end of a steel pipe to facilitate mechanical connections between pipes or fittings. This connection method is typically suitable for smaller-diameter steel pipes, offering advantages such as convenience and disassemblability. No welding is required during installation, enabling quick installation and maintenance. Couplings are fittings used to connect two sections of steel pipes. Common thread types include external threads and internal threads, with the former typically located at the end of the pipe and the latter used for connecting to fittings or other pipes. The use of couplings makes the extension and modification of pipeline systems more flexible. Threaded couplings are suitable for low-pressure and ambient temperature environments, while welded couplings offer higher strength and sealing performance, making them suitable for high-temperature and high-pressure applications.
The combination of steel pipes with threading and couplings further enhances the reliability and durability of pipeline systems. In industries such as petroleum, natural gas, and chemicals, steel pipes equipped with threading and couplings have become the preferred material for energy transmission and industrial manufacturing, ensuring system safety and stability.
