The threaded couplings have a straight channel and an internal thread connection. They are suitable for piping systems in many industries, used to extend pipes, connect pipes, or connect with other accessories, through the straight channel of the inner wire joint, so that the fluid can pass through the joint smoothly.
They can be manufactured with many kinds of steel, such as carbon, galvanized, stainless, or black. Since stainless steel has excellent corrosion resistance and high-temperature resistance and is suitable for the transportation and control of a variety of media, it is considered the best material and is widely used.
Unlike other pipe-fitting connectors, it is highly flexible and adjustable. Stainless steel thread couplings usually have threads and are used to mate with the threaded portion of the pipe or pipe to achieve fastening and connection.
Stainless steel threaded couplings are sized based on specific needs and applications. Common specifications include grade of material, thread type, thread size, pipe diameter, length and surface treatment, etc. According to the design and requirements of the piping system, select the appropriate size to achieve a tight and stable connection effect.
