Steel Pipe

Steel Searcher-Steel Pipe having a hollow section much longer than its diameter or circumference. According to the sectional shape, it can be divided into round, square, rectangular and special-shaped steel tubes; According to the material is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe; According to the purpose, it can be divided into conveying pipeline, engineering structure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high pressure equipment and so on.

Types of Steel Pipe

Steel Pipe
Hot Galvanized Steel Pipe
Pipe galvanizing is a coating process that gives steel pipe a zinc coating to prevent corrosion and rust. Pipe galvanizing was widely used in residences constructed.
Spiral Tube
SSAW steel pipe is made up of hot-rolled coiled steel using a double-sided submerged arc welding method.
Welded Pipe
Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates.
Seamless Steel Tube
The seamless steel pipe is made of perforated whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe.
Square Steel Pipe
Square steel pipes are steel pipes with equal side lengths, which are rolled from strip steel through process treatment.
Rectangular Steel Pipe
Rectangular tubes are formed from coils and then ran through a series of dies.
Material Preparation

Steel pipe is made of a very high quality kind of round steel as the main material.

Tube Billet Heating

The principle of perforation is to use high temperature make the round steel for a softening work and then the top of the middle of the solid part are all removed. This time it becomes hollow round steel, which is what we see seamless steel pipe.

Oblique Rolling Perforation

Then do the round steel perforation, in the process of perforation, when the solid round steel turns into a hollow round steel.


Then Straightening, inner grinding, deviation correction, outer grinding, flaw detection, finishing, final inspection and packaging.
