Seamless steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances that can flow — liquids and gases (fluids), slurries, powders and masses of small solids.

Seamless Pipe (and tubing) is made by extruding a steel block or by drilling a solid steel bar. Next, the extrusion or the drilled steel bar is cold drawn through a dye to achieve the diameter and thickness needed. Because this process can cause mechanical hardening, sometimes the material is annealed and straightened as a final process. Seamless Pipe & Tubing is subdivided as:

Cold Drawn Seamless, or CDS, exhibits precise tolerances and a good surface finish.

Hot Finished Seamless or HFS has less critical tolerances and a somewhat scaly finish and is not as strong as CDS.

For Drawn over Mandrel, or DOM tubing, the first stages of manufacturing are identical to the ones used to make electric resistance welded tubing, but in the finishing stages the entire flash weld is taken out and the tube is cold drawn over a mandrel. A mandrel is a round object against which material can be forged or shaped. The cold-drawn process provides the tube with better dimensional tolerances, improved surface finish and the strongest weld strength achievable.

EN10210 & EN10216

EN10210 and EN10216 are both European standards for steel pipes.

EN10210 specifies technical delivery conditions for hot-finished hollow sections of circular, square, rectangular or elliptical forms, while EN10216 specifies the technical delivery conditions in two parts for seamless steel tubes for pressure purposes.

EN10210 is intended for structural hollow sections and applies to hollow sections formed from non-alloy steel, fine grain steel, or steel with specified minimum impact properties at temperatures not lower than -20°C. It covers sizes ranging from 21.3mm to 660mm in diameter and wall thicknesses from 2mm to 50mm.

EN10216 applies to non-alloy and alloy steel pipes with specified properties for high-temperature service. It covers sizes ranging from 10.2mm to 711mm in diameter and wall thicknesses from 1.6mm to 100mm. Part 1 of the standard specifies the technical delivery conditions for pipes made of non-alloy and alloy steel with specified properties at room temperature or at elevated temperatures, while Part 2 specifies the technical delivery conditions for pipes of non-alloy and alloy steel with specified properties at low temperatures.
