Product DescriptionSeamless 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.1.Steel
Tubing is a hollow steel shape intended for structural
purposes and made from carbon, stainless, or galvanized steel
further divided as:·Mechanical Tubing is used in low stress
applications such as fences, kitchens, restaurants, hospitals,
solar panels and made with wall thicknesses up to 10
gauge.·Structural Tubing is for high stress structural
application like bridges, buildings, roll cages, and underwater
platforms with wall thickness from 3/16" and up. It is often
referred to as Hollow Structural Sections or just the acronym
HSS.2.Pipe is a hollow structure that is intended to carry
material such as liquids, gasses, or even solids. Its wall
thickness is described by its Schedule and it is often broken down
by type using the method of manufacturing it, either ERW or
Seamless.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.Product SpecificationStandardAPI, ASTM,

The tubes therefore have only low deformability.Cold-finished/soft

light finishing pass (cold drawing) With proper subsequent
processing, the tube can be cold-formed (e.g. bent, expanded)
