Steel pipe [ท่อ เหล็ก สเตย์, which is the term in Thai] is a hollow steel shape meant for structural functions as well as made from stainless, carbon, or galvanized steel additionally divided as:

Mechanical tubing is used in low tension applications, such as fences, restaurants, cooking areas, photovoltaic panels, health centers, and made with wall thicknesses as much as 10 gauge.
Architectural Tubes is for a high-stress architectural application like bridges, roll cages, buildings, and undersea platforms with wall density from 3/16″ as well as up. It is commonly referred to as hollow structural areas or just the phrase HSS.

The pipe is a hollow framework that is meant to bring material such as gasses, fluids, or even solids. Its wall thickness is defined by its Schedule as well as it is commonly broken down by type utilizing the technique of making it, either Smooth or ERW.

How it’s made?

Both tubes, as well as pipes, are made by the first two techniques below. The third is reserved for tubes only.

Electric Resistance Welded, often abbreviated as ERW, is a process that utilizes detailed equipment to form the pipe as well as tubes. A steel sheet is unwound from a coil, as well as shaped making use of contoured rollers, compelling the edges together under pressure. These edges are then welded with each other by warming the product to over 2,000 degrees. After welding, the tubing or pipe is cut right into the specific size required.

Smooth Pipeline, and tubing, are made by squeezing out a steel block or by piercing a strong steel bar. Next, the extrusion or the drilled steel bar is chilly drawn with color to accomplish the diameter, as well as density needed. Since this process can create mechanical hardening, occasionally the product is annealed and straightened as the last procedure. Smooth pipe and tubing are subdivided as:

Cold Drawn Seamless, or CDS, displays precise tolerances as well as a good surface area finish.

Hot Finished Seamless, or HFS, has much less critical tolerances and rather a scaly surface as well as is not as solid as CDS.
