In general, carbon steel pipe fittings and flanges are widely used for applications which do not require materials with higher resistance to corrosion such as stainless steel and alloy steel. Carbon Steel Fittings is primarily used across piping systems for its hardness, moderate to good tensile strength and inexpensiveness.

Butt weld fittings are manufacture by seamless or welded pipe. For pipe fittings manufacturers, the forming process of welded pipe and seamless pipe is basically same. Butt welded fittings can be divided into carbon steel butt welded fittings and stainless-steel butt-welded fittings
