Pipe fittings are essential auxiliary accessories in a pipeline system, facilitating the connection, diversion, and regulation of flow within the pipeline. Our offerings include a range of steel pipe fittings designed for pipelines. Categorized by different processes, steel pipe fittings are mainly classified into flanges, threaded pipe fittings, and butt-welding pipe fittings. When purchasing butt-welded pipe fittings, it is imperative to specify whether they are welded or seamless.
