Types of Steel Pipe

In advancement of technology era, Steel pipes are not just hollow cylindrical tubes made from steel, but also they have the variety of features in manufacturing and construction industry. Types of steel pipes due to application requirements in building and construction. In 2021-2022, the production of steel pipes in South Korea Is expected to increase sharply to around 4.22 to 4.63 million metric tons.Before buying steel pipe, you need to know all types of steel pipes. This article will also help you to sort out this most nagging question: “Which type of steel pipe are you looking for?”

In this article we will discuss the various types of steel pipes, and their applications and uses for different purposes in manufacturing and construction industry. Let the UNIASEN Carbon Steel Pipe Supplier now review the types of steel pipes and see which type suits your needs.

Carbon steel pipe

The most familiar type that covers above 85% of the total steel pipe manufacturing industry is known as carbon steel pipe. For manufacturing purpose, steel pipe supplier prefers carbon steel pipes. Research indicates that concentrated sulfuric acid is a major thing that becomes the reason of corrosion in carbon steel pipes.

Some of the salient features of carbon steel pipe are listed below:

  • Advanced ductility
  • Non-bending nature
  • Tensile and durable
  • Corrosion-resistance
  • Harder
  • Welded
  • high mechanical performance
  • Recycle
  • Less costly

Top application of carbon steel pipes

  • The most typical application of carbon steel pipes is transporting water, sewage and other fluid.
  • They play role in construction of various machinery parts in ship building and transportation of fluids such as water and oil.
  • Carbon steel pipes show vital role in manufacturing industry, building foundation and constructive project.
  • Carbon steel pipes are most suitable for construction of automobiles like motor car, taxis and buses
  • These pipes used in medical industry

Stainless steel pipes

These are hollow round long steel pipes which are widely used in manufacturing and industrial transportation. In manufacturing of high temperature bearing part of aero engines 660 stainless steel is suitable. 316 series can be welded. 904L Stainless steel pipe and 304 grade are superior corrosion resistance. Stainless steel has light weight this property indicates their role in manufacturing industry.

Top application of stainless steel pipe

  • Equipment and apparatus
  • Medicines
  • Food
  • Light
  • Oil and chemical industry
  • Furniture
  • Manufacturing of mechanical parts

Stainless steel pipes are more durable than carbon steel pipes. Click the URL to learn more: One of the major disadvantage is highly cost. It has been proved that 3-D FE model and 2-D axisymmetric FE mode can accurately predict residual stress distributions for SUS304 stainless steel pipe.

Galvanizing steel pipes

It is a type of steel pipe that is coated with zinc and highly resistance to corrosion and rust. The lifespan of galvanizing pipe approximately 45 years. It is the best choice for home plumbing but not suites for gas lines.

Application of galvanizing steel pipes

  • Home plumbing
  • Handrails and fences
  • Transporting portable water and fluid
  • Industrial piping system
  • Oil industry
  • Automobile industry
  • Construction purposes

Benefits of galvanizing pipe

There are some characteristics of galvanizing pipes that make them unique and beneficial on an industrial level:

  • These pipes are corrosion resistance.
  • They have prolonged service life.
  • Galvanizing steel pipes can be welded.
  • These pipes are more durable than carbon steel pipes.
  • Galvanizing steel pipes have high operational convenience and mechanical performance.

Alloy steel pipes

It is a type of steel pipe that is formed by mixing of steel with other elements. These elements are called alloying elements. Chromium, copper, and silicon are some common alloying elements. These alloying elements determine the mechanical and chemical properties of steel. These elements protect against oxidation.  Alloy steel pipes are more resistance to corrosion than carbon steel pipes due to mixing of other elements.

Properties of alloy steel pipes:

The following are some physical, chemical and mechanical properties that distinguish them from other steel pipes:

  • Alloy steel pipes are typically stronger than conventional carbon steel pipes.
  • They are more ductile.
  • Alloy steel pipes have a higher strength and can tolerate high pressure.
  • Their chemical composition varies due to specific grades. 140 (chromium-molybdenum), 4130 (chromium-molybdenum-silicon), 52100 (chromium), 1020 (carbon), 8620 (nickel-chromium-molybdenum) and T304/L (stainless steel) are most commonly used grades.
  • Due to lower carbon content they can be welded easily.

Top application of alloy steel pipes

  • Automobiles and exhaust system
  • Power plants
  • Construction project
  • Household
  • Nuclear power
  • Manufacturing industries
  • Gas processing
  • Pharmaceutical equipment
  • Paper industry
  • Medical engineering
  • Aircraft turbines

Hence, alloy steel pipes are very suitable for manufacturing and 100% recyclable.


There are different types of steel pipes based on the materials used in manufacturing which helps in fulfilling the required purposes especially the strength and flexibility. As each steel pipe has its own selectable properties so up you can choose from it as per your requirement.
