How many types of seamless steel pipes are there on the market today?
There are many types of seamless pipes on the market, depending on the seamless steel standard, application, and size. Below are the 13 most common types of seamless steel pipes on the market today.
Cold-rolled seamless steel pipes
“Cold rolled seamless steel pipe is a type of seamless pipe produced by passing the pipe through cold rolling rollers, with the English name Cold Rolled Steel Pipe.
->The hot rolling process will reduce the outside diameter and thickness of the tube. While the length of the tube increases. Thereby increasing uniformity and improving the gloss and smoothness of the tube surface.
Cold-rolled seamless pipes have diameters ranging from 6mm to 200mm and thicknesses ranging from 0.5mm to 8mm. Additionally, cold-rolled seamless pipes can be manufactured from different steel grades, such as carbon steel, alloy steel, and stainless steel, depending on the specific application.
Cold-rolled seamless tubes are used in applications requiring high precision. For example, in the automobile and motorcycle industries, oil pipes and vehicle parts In addition, this type of pipe is also used in fitness equipment, hydraulic cylinders, air cylinders,…
Hot-rolled seamless steel pipes
“Hot-rolled seamless steel pipe is a type of pipe produced by passing the molded pipe through hot-rolling rollers. Hot rolled seamless steel pipe has the English name Hot Rolled Seamless Steel Pipe.
Hot-rolled seamless pipes often have specifications such as:
- Diameter from 21.3mm to 508mm
- Thickness from 2.11mm to 40mm.
This type of pipe is widely used in the gas, oil, chemical, and water pipeline industries, in machinery manufacturing, factory structures, etc.
Hot-rolled seamless pipes are often used in applications that require high durability, pressure resistance, high-temperature resistance, abrasion resistance, and good corrosion resistance. However, hot-rolled seamless pipes also have some limitations as follows:
- It is difficult to control the precision of the size and shape of the tube
- The gloss and smoothness of the surface are not high
- The price is higher than cold rolled pipes
If you want to consolidate your knowledge about hot-rolled steel pipes and cold-rolled steel pipes, you can refer to Bao Tin Steel’s article distinguishing between hot-rolled steel and cold-rolled steel.
Carbon seamless steel pipes
“Carbon seamless steel pipe is a type of seamless pipe produced from carbon steel, a material with good strength and good elasticity.”
Carbon seamless steel pipe can be manufactured in various diameters and thicknesses to suit specific applications. Carbon seamless steel pipes are often classified according to their thickness and diameter. In addition, they can also be manufactured with different properties, such as hardness, ductility, strength, and corrosion resistance, to suit different applications.
However, carbon seamless steel pipe also has some limitations, such as not being resistant to oxidation and reacting with strong acids. And it can corrode and rust if used in high humidity or in strongly acidic environments.
Carbon seamless steel pipe carbon is mainly supplied to the transportation industry, the oil and gas industry, etc. Due to its seamless structure, seamless steel pipe carbon can meet the requirements of pipe systems with high pressure, temperature, and resistance. For example, metallurgy, petrochemicals, chemical plants, the energy industry, petroleum systems, boiler systems, etc.
Stainless seamless steel pipe
“Stainless steel seamless pipes are pipes manufactured from stainless steel. This is a material that can withstand corrosion and oxidation well, especially in humid, acidic, and alkaline environments.
Hot-dip galvanized seamless steel pipes
A hot-dip galvanized seamless steel pipe is a seamless steel pipe that is plated with a layer of zinc by passing the pipe through a hot-dip galvanising tank. This process will create a durable zinc coating to protect the cast pipe from corrosion and increase the durability of the product.
Hot-dip galvanized seamless steel pipes are often used in applications that require sustainability, high durability, and corrosion resistance. They are commonly used in civil and industrial applications such as water supply systems, wastewater treatment systems, and electrical, mechanical, and construction systems.
Types of structural seamless steel pipes
“Structural seamless steel pipes are used to manufacture factory structures, bridges, roads, oil and gas rigs, scaffolding, and other construction projects.” This type of pipe is usually produced from carbon steel or alloy steel. There are different diameters and thicknesses to suit specific applications.
seamless steel pipe structure has good strength, pressure resistance, and high-temperature resistance. Especially in applications requiring high stability.
However, when using structural cast pipes, it is necessary to ensure the safety of the structure. By using standards and regulations for design, installation, and operation. In addition, periodic maintenance and inspection measures need to be carried out to ensure the safety and durability of the structure.
Boiler seamless steel pipe
Boiler seamless steel pipes are commonly used in the construction industry, metallurgical industries,…
seamless steel pipe in a high-pressure furnace
As the name suggests, “seamless steel pipes in high-pressure furnaces are cast pipes used to conduct oxygen and gas into blast furnaces during the iron production process.”
So do you know what a blast furnace is? If you don’t know, a blast furnace is a large industrial piece of equipment used to produce pig iron from iron ore, coke, and limestone.
Types of seamless steel pipes for carrying chemicals
Seamless oil pipe
“Seamless oil pipe is a type of steel pipe used to carry oil and other liquids in oil pipeline systems in the oil and gas industry.
Pipes must meet the requirements for strength, corrosion resistance, and high-temperature durability. Oil pipes are usually manufactured from carbon steel or alloy steel. Additionally, they can also be produced in different diameters and thicknesses. To suit specific applications in the oil and gas industry.
However, you need to ensure the quality of the pipe, its installation, and its operation according to regulations. At the same time, carry out periodic maintenance and inspection measures to ensure the safety and durability of the oil pipeline system.
Gas-conducting seamless steel pipes
“Seamless gas pipeline is a type of steel pipe used to conduct gases. Such as natural gas, gas, industrial gas, liquefied petroleum gas, and other gases.”
Types of hydraulically seamless steel pipes
“Hydraulic seamless steel pipe is a type of steel pipe used to transmit and bear pressure in hydraulic systems in industry, construction, and other industries.”
Super thick seamless steel pipe
“Super thick seamless steel pipes are steel pipes with a greater thickness than regular pipes. Often used in applications requiring high strength and high-temperature resistance.”
- Oil delivery system
- Gas pipeline system
- Hot water system
- Steam pipeline system
- Industrial machinery parts
- Execution of construction projects
To ensure system security, you need:
- Install and operate in accordance with regulations. Carry out
- periodic maintenance and inspection measures
- Features and applications of each type
- Reputable address for supplying seamless steel pipes
- Especially the price of seamless steel pipe products,….
