What are the types of seamless steel pipes?

Firstly, seamless steel pipes have a hollow cross-section, and many of them are used as pipelines for transporting fluids, such as oil, gas, liquefied gas, water, and some solid raw materials. Compared with solid core stainless steel plates such as round steel, seamless steel pipes have a relatively light net weight when their bending strength, torsion strength, and compressive strength are the same, making them an economically developed cross-sectional steel. The surface of hot-dip galvanized seamless pipes has undergone hot-dip galvanizing and an additional layer of corrosion-resistant and rust proof zinc treatment.

Secondly, essential resource materials include 10 #, 20 #, 35 #, 45 #, and 16Mn. Among them, 20 # is widely used, and 16Mn is also commonly referred to as Q345B by some people.

Thirdly, the main uses of seamless steel pipes generally include the following categories:

1. Architecture majors include: underground pipeline transportation, extracting surface water when building houses, and transporting water from heating furnaces.

2. Mechanical processing manufacturing, roller bearings, production and processing machinery equipment manufacturing, etc.

3. Electrical majors: natural gas transmission, water and electricity generation fluid pipelines.

4. Anti static pipes, etc. for wind power plants.

Fourthly, according to different main uses, pipes can be classified into the following categories:

1. High pressure fertilizer pipes GB6479-2000 can be used in chemical plants and pipelines with temperatures ranging from -40 to 400 ℃ and pressures ranging from 10-32Mpa.

2. GB/T8163-2008 is a general seamless steel pipe suitable for conveying fluids.

3. General structural pipes GB/T8162-2008 and GB/T8163 are suitable for general construction, engineering project support frames, mechanical processing and manufacturing, etc.

4. Petroleum waterproof casing ISO11960 oil pipeline is used as the wellbore for extracting oil or gas from oil and gas wells.

 Fifthly, it is widely used to manufacture components and mechanical parts, such as petroleum drilling tools, transmission shafts, bicycle frames, and steel pipe scaffolding used in construction projects. Seamless steel pipes are used to manufacture circular parts, which can improve the utilization rate of raw materials, simplify the manufacturing process, save raw materials and production and construction time. Seamless steel pipes have been widely used for manufacturing.
