Seamless 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.

Application
Carbon steel pipe and tube are used in high-pressure conditions. They are highly resistant to shock and vibration, making it ideal to transport fluids. Carbon steel pipes are widely used in a number of industries, such as construction material, buidlings, bridges, transporting water and sewage, oil and gas industries, boiler and condenser tubes, high-pressure applications, and chemical processing.
- Construction material / bridges
- Transporting water and sewage
- Oil and gas industries
- Boiler and condenser tubes
- High-pressure applications
- Chemical processing
Hot Finished Seamless, or HFS, has less critical tolerances and somewhat scaly finish and is not as strong as CDS.
ASTM A106 A53 X42-X80 Oil and Gas Carbon Steel Seamless Steel Pipe is a commonly used metal pipe composed of elements such as carbon and iron. It has good mechanical properties and corrosion resistance. Extensively evaluated in petroleum, chemical industry, aviation, aerospace, construction and other fields. Carbon steel pipes can be divided into seamless steel pipes, welded steel pipes, precision steel pipes, etc.
