Fluid Steel Pipe

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 somewhat scaly finish and is not as strong as CDS.
Seamless Steel Pipe, as the name s ests, is a pipe without a seam or a weld-joint. Seamless steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow - liquids and gases (fluids), slurries, powders and masses of small solids.
Ends: Plain end/Beveled, protected by plastic caps on both ends, cut quare,grooved,threaded and coupling, etc.
Surface Treatment: Bare, painting black, varnished, galvanized, anti-corrosion 3PE PP/EP/FBE coating.
