1020 THICK WALL STEEL PIPE HEAVY WALL STEEL TUBING
The steel pipe whose ratio of outer diameter to wall thickness is less than 20 is
called thick wall steel pipe. It is mainly used as petroleum geological drilling pipe,
cracking pipe for petrochemical industry, boiler pipe, bearing pipe,
high-precision structural pipe for automobile, tractor and aviation, etc.
The difference between thick wall steel pipe and thin wall steel pipe lies in the thickness of steel pipe wall.
Generally speaking, thin wall steel pipe is cold drawn technology,
and thick wall steel pipe is generally hot rolled technology.
If it is distinguished by measurement unit, it is generally considered that wall thickness / pipe diameter
equal to 0.02 is the watershed between thick wall steel pipe and thin wall steel pipe,
and wall thickness / pipe diameter less than 0.02 is thin wall steel pipe,
Larger than is the thick wall steel pipe.
In terms of application, thin-wall steel pipe is mostly used on the pipe.
The thick wall steel pipe is mostly used in the blank of hollow parts.
Used on pressure bearing and important pipelines.
Thick walled steel pipes are mainly used in tap water engineering, petrochemical industry,
chemical industry, electric power industry, agricultural irrigation and urban construction.
For liquid transportation: water supply and drainage.
For gas transmission: gas, steam and liquefied petroleum gas.
For structure: as pile driving pipe and bridge;
Pipes for wharf, road, building structure, etc.
