Seamless steel pipes are an important steel material variety, widely used in construction, petroleum, chemicals, machinery, and other fields. According to different application needs, seamless steel pipes can be divided into many types. In this article, we will introduce the types and applications of seamless steel pipes in detail.
Types of Seamless Steel Pipes
Classification by Usage
(1) Seamless pipes for fluid transportation: mainly used for transporting fluids such as petroleum and natural gas in pipelines, with specifications ranging from Φ159-426mm.
(2) Galvanized seamless pipes for low-pressure fluid transportation: mainly used for transporting water, gas, and air in low-pressure pipelines, with specifications ranging from Φ10-159mm.
(3) Seamless pipes for oil transportation: mainly used for transporting oil and natural gas in pipelines, with specifications ranging from Φ219-426mm.
(4) Seamless pipes for fertilizer equipment: mainly used for transporting chemicals such as ammonia and urea, with specifications ranging from Φ219-426mm.
(5) Seamless pipes for deep-well pumps: mainly used for extracting groundwater, with specifications ranging from Φ76-168mm.
Classification by Surface Quality
(1) Seamless pipes with good surface quality: These pipes have a good surface quality, with no defects such as oxidation or cracks, and can be used in high-pressure boilers, petroleum cracking, chemical equipment, and other applications.
(2) Seamless pipes with poor surface quality: These pipes have surface defects such as oxidation or cracks, and can be used in low-pressure fluid transportation, agricultural irrigation, and other applications.
Classification by Material
(1) Common carbon steel seamless pipes: These pipes are made of common carbon steel and are commonly used in low-pressure fluid transportation, agricultural irrigation, and other applications.
(2) Low-alloy steel seamless pipes: These pipes contain certain alloying elements and are commonly used for transporting fluids such as petroleum and natural gas at high pressures.
(3) Stainless steel seamless pipes: These pipes are made of stainless steel and are commonly used in food, pharmaceutical, and other industries due to their corrosion resistance and hygiene features.
Applications of Seamless Steel Pipes
Seamless steel pipes are a crucial steel material variety that is widely used in various fields. The following sections will introduce their applications in construction, petroleum, chemicals, machinery, and other industries.
- In the construction industry, they are widely used for important structures such as high-rise buildings, cold storage facilities, and roof waterproofing, serving as load-bearing and waterproof components.
- In the petroleum industry, they are also extensively utilized for the construction and installation of petroleum pipelines, petroleum storage tanks, and other equipment. Due to their corrosion resistance, high-temperature resistance, and high-pressure resistance, seamless steel pipes have gained widespread application.
- In the chemical industry, they are also widely used for the transportation of chemical raw materials such as ammonia, urea, methanol, etc. Since these media are often corrosive, seamless steel pipes are required to ensure the safe operation of pipelines.
- In the machinery industry, they are widely used for manufacturing automotive, tractor, and other agricultural machinery components. Due to their high strength, corrosion resistance, and other characteristics, seamless steel pipes have been widely used.
