Different types and uses of seamless steel pipe

Date:2024-05-14Tags:Seamless steel pipe,Stainless steel seamless steel pipe

Seamless steel pipe is a steel pipe made in a unique way. It does not require welding during the production process and therefore has high strength and pressure resistance. Because of their different manufacturing processes, they are divided into two types: hot-rolled (extruded) seamless steel pipes and cold-drawn seamless steel pipes. Cold drawn tubes are divided into round tubes and special-shaped tubes. A steel pipe without seams along the perimeter of its cross-section. According to different production methods, they are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, pipe jacking, etc.all of which have their own process regulations. Seamless steel pipe is an important steel product widely used in construction, petroleum, chemical industry, machinery and other fields. Seamless steel pipes can be divided into many types according to different application requirements. The editor has sorted out the types and applications of seamless steel pipes for everyone.

1. Classification by use: Seamless steel pipes can be divided into the following categories according to use.

Seamless steel pipe for fluids: mainly used for transporting oil, natural gas and other fluid pipelines, the specification is generally Ф159.426mm.

Galvanized seamless steel pipe for low-pressure fluid transportation: mainly used to transport low-pressure fluids such as water, gas, and air. The specifications are generally 10-159mm.

Seamless steel pipes for transporting petroleum: Mainly used for transporting fluid pipelines such as petroleum and natural gas. The specifications are generally Ф219-426mm.

Seamless steel pipes for fertilizer equipment: mainly used to transport chemical raw materials such as ammonia and urea. The specifications are generally Ф219-426mm.

Seamless steel pipes for deep well pumps: mainly used for transporting groundwater, with specifications generally ranging from 76 to 168 mm.


2. Classification by material

Carbon structural steel seamless steel pipe: with carbon as the main alloy element, it has low cost and good welding performance, and is widely used in various structural parts.

Low-alloy high-strength structural steel seamless steel pipe: Adding a small amount of alloy elements to low-carbon steel to improve the strength and toughness of the steel, suitable for large-scale steel structures.

Alloy structural steel seamless steel pipe: contains more alloy elements, has higher strength and toughness, and is suitable for harsh environments such as high temperature, high pressure, and high corrosion.

Stainless steel seamless steel pipe: has good corrosion resistance and aesthetics, and is widely used in chemical industry, medical treatment, food and other fields.


4. Classification by cross-sectional shape

Circular seamless steel pipe: With a circular cross-section, it is the most common form of seamless steel pipe and is suitable for various application scenarios.

Square seamless steel pipe: with a square cross-section, high rigidity and load-bearing capacity, it is suitable for construction, machinery and other fields.

Rectangular seamless steel pipe: rectangular in cross-section, has good bending resistance and stability, and is suitable for bridges, vehicles and other fields.


Applications of seamless steel pipes

Seamless steel pipe is a very important type of steel that is widely used in various fields. The following introduces the applications of seamless steel pipes in construction, petroleum, chemical industry, machinery and other fields.


Construction sector
Seamless steel pipes are widely used in the construction field. They are mainly used in important structures such as high-rise buildings, cold storages, and roof waterproofing to play load-bearing and waterproofing functions.


Petroleum field
Seamless steel pipes are also widely used in the petroleum field, mainly used in the construction and installation of petroleum pipelines, petroleum storage and other equipment. Seamless steel pipes are widely used because of their corrosion resistance, high temperature resistance, and high pressure resistance.


Chemical industry
Seamless steel pipes are also widely used in the chemical industry, mainly used to transport ammonia, urea, methanol and other chemical raw materials. Since these media are often corrosive, seamless steel pipes are required to ensure safe operation of the pipelines.


Mechanical field
Seamless steel pipes are also widely used in the machinery field, mainly used to manufacture parts for agricultural machinery such as automobiles and tractors. Seamless steel pipes are widely used due to their high strength and corrosion resistance.
