Steel pipe is a widely used steel product, and there are many types, which are classified according to different factors such as production process, material, and use. Some common steel pipe classifications and their uses are listed below:
Classified by production process:
a) Seamless steel pipe: Seamless steel pipe is a steel pipe that has no welds throughout the entire process of the steel pipe. It is usually used for high pressure transportation, such as oil, natural gas, gas, water, etc.
b) Welded steel pipe: Welded steel pipe is a steel pipe in which the edges of steel plates or strip coils are welded into a cylindrical shape. Welded steel pipes are divided into straight seam welded steel pipes and spiral welded steel pipes. Mainly used in low-pressure fluid transportation, building structures and other fields.
Classified by material:
a) Carbon steel pipe: Carbon steel pipe is a steel pipe made of carbon steel, which is mainly used in industrial and civil construction, conveying low-pressure fluid and other fields.
b) Stainless steel pipe: Stainless steel pipe is a kind of corrosion-resistant steel pipe, which is mainly used in food, chemical, petroleum, pharmaceutical and other industries, as well as transporting corrosive fluids.
c) Alloy steel pipe: Alloy steel pipe is a steel pipe made of alloy material, which usually has high strength and wear resistance, and is widely used in petroleum, chemical, aviation, aerospace and other fields.
Classified by purpose:
a) Conveying pipe: used to convey oil, natural gas, gas, water and other fluids, such as seamless steel pipe, welded steel pipe, etc.
b) Structural tubes: used for building structures, bridges, supports, etc., such as square tubes, rectangular tubes, round tubes, etc.
c) Automobile tubes: used in the manufacture of auto parts, such as auto bearings, brake systems, etc.
d) Oil well pipe: used in oil drilling, oil production and other fields, such as oil casing, drill pipe, etc.
e) Boiler tubes: used in the manufacture of boilers, heat exchangers, etc., which need to withstand high temperature and high pressure.
f) Mechanical tubes: used to manufacture various mechanical parts, such as bearings, gears, transmission shafts, etc.
g) Pipes for steel bars: used to produce steel bars, widely used in construction, bridges, roads and other projects.
In conclusion, steel pipes have various classifications and uses, which means they can be applied in different industries and engineering projects. When selecting steel pipes, it is necessary to determine the appropriate steel pipe type according to actual application requirements and environmental conditions.
Here are some other types of steel pipe and their uses:
h) Wire duct: used for laying electrical lines to protect cables from damage.
i) Hydraulic strut pipe: used in hydraulic support systems in coal mines, oil drilling and other fields.
j) High-pressure gas cylinder tube: used to manufacture high-pressure gas cylinders, such as oxygen cylinders, nitrogen cylinders, etc., which need to withstand high pressure.
k) Thin-walled pipe: steel pipe with small wall thickness, used in manufacturing industries such as furniture and home appliances.
l) Pressure tube: used in the manufacture of pressure vessels, heat exchangers and other equipment that need to withstand high pressure and high temperature.
m) Steel pipe piles: steel pipes used in foundation works such as bridges and building foundations.
n) Precision steel pipe: used to manufacture high-precision mechanical parts, such as cylinders, bearings, etc.
o) Steel-plastic composite pipe: A layer of plastic material is coated on the inner and outer surfaces of the steel pipe to improve the corrosion resistance of the steel pipe. It is widely used in water supply and drainage, HVAC and other fields.
p) Steel pipe pallet: used to manufacture storage equipment such as shelves and storage racks.
Here are a few things to consider when choosing the right steel pipe:
Understand the actual needs of engineering projects, including engineering environment, pressure, temperature, etc.
Familiar with the production process and material characteristics of steel pipes to choose the most suitable steel pipe type.
Considering the budget and cost factors, select the appropriate steel pipe under the premise of meeting the engineering requirements.
The most important thing is to choose suppliers and manufacturers with good reputation and product quality assurance.
If you want to source from China, Royal Group would be a good choice.
