Description: Pipe is a tubular product intended primarily for such purposes as the conveying of water, fuel, gas, air, steam, etc. It has also been found to be a convenient form for use as structural members such as columns and railings. It is produced from steel in a variety of analyses by the welded, seamless, and extrusion methods. As distinguished from tubing, pipe is commonly produced in greater quantities and in relatively few standard sizes. It is generally made to less exacting specifications for dimensions, finish, chemical composition, and mechanical properties than tubing. Sizes and wall thicknesses of pipe were originally standardized to permit threading the end for joining lengths with couplings or other connectors. A large proportion of the product is also used without screw threads (plain end), where lengths are joined together, or fittings attached, by welding or other means. Pickling & Oiling is a treatment that consists of passing the metal through an acid to remove surface oxides, and then rinsing and oiling the metal to reduce the formation of rust.
Application: A general purpose pipe, most commonly used in steam, water, gas and air lines.

Description: Pipe is a tubular product intended primarily for such purposes as the conveying of water, fuel, gas, air, steam, etc. It has also been found to be a convenient form for use as structural members such as columns and railings. It is produced from steel and aluminum in a variety of analyses by the welded, seamless, and extrusion methods. As distinguished from tubing, pipe is commonly produced in greater quantities and in relatively few standard sizes. It is generally made to less exacting specifications for dimensions, finish, chemical composition, and mechanical properties than tubing. Sizes and wall thicknesses of pipe were originally standardized to permit threading the end for joining lengths with couplings or other connectors. A large proportion of the product is also used without screw threads (plain end), where lengths are joined together, or fittings attached, by welding or other means.
Application: Suitable for welding, coiling, bending, and flaring.
