Seamless Steel Tubes: Types and Applications

Seamless steel tube is an important steel variety that is widely used in construction, petroleum, chemical, mechanical, and other fields. Depending on different application needs, seamless steel tubes can be divided into various types. This article will introduce the types and applications of seamless steel tubes.

Types of Seamless Steel Tubes:

1. Classification by application

They can be classified by their application into the following types:

(1) For fluid transportation: mainly used for transporting fluids such as oil and natural gas in pipelines, with specifications typically ranging from Φ159-426mm.

(2) For low-pressure fluid transportation: mainly used for transporting low-pressure fluids such as water, gas, and air, with specifications typically ranging from Φ10-159mm.

(3) For oil transportation: mainly used for transporting fluids such as oil and natural gas in pipelines, with specifications typically ranging from Φ219-426mm.

(4) For fertilizer equipment: mainly used for transporting chemical raw materials such as ammonia and urea, with specifications typically ranging from Φ219-426mm.

(5) For deep well pumps: mainly used for transporting groundwater, with specifications typically ranging from Φ76-168mm.

2. Classification by surface quality

They can be classified by their surface quality into the following types:

(1) Tubes with good surface quality: these tubes have good surface quality, without defects such as oxidation or cracks, and are suitable for high-pressure applications such as boilers, petroleum cracking, and chemical equipment.

(2) Tubes with poor surface quality: these tubes have surface defects such as oxidation or cracks, and are suitable for low-pressure fluid transportation or agricultural irrigation applications.

3. Classification by material

They can be classified by their material into the following types:

(1) Common carbon steel seamless steel tubes: made of common carbon steel, these tubes are commonly used in applications such as low-pressure fluid transportation or agricultural irrigation.

(2) Low-alloy steel seamless steel tubes: containing a certain amount of alloy elements, these tubes are suitable for high-pressure fluid transportation such as oil and natural gas.

(3) Stainless steel seamless steel tubes: made of stainless steel, these tubes are commonly used in industries such as food and pharmaceuticals due to their corrosion resistance and hygienic characteristics.

Applications:

Seamless steel tubes are a very important type of steel and are widely used in various fields. Below, we will introduce the applications of seamless steel tubes in the fields of construction, oil, chemicals, machinery, and more.

In the field of construction, they are widely used in high-rise buildings, cold storage, roof waterproofing and other important structures, playing a role in load bearing, waterproofing, etc.

In the field of petroleum, they are also widely used in the construction and installation of equipment such as oil pipelines and oil storage tanks. Because seamless steel tubes have the characteristics of corrosion resistance, high-temperature resistance, and high-pressure resistance, they have been widely used.

In the field of chemicals, they are also widely used in the transportation of chemical raw materials such as ammonia, urea, methanol, etc. Because these media often have corrosive properties, seamless steel tubes are needed to ensure the safe operation of pipelines.

In the field of machinery, they are also widely used in the manufacturing of parts and components for agricultural machinery such as automobiles and tractors. Because seamless steel tubes have high strength and corrosion resistance, they have been widely used.
