Types of Oil & Gas Pipes: Seamless and ERW

Seamless pipes

Steel billets are heated and perforated to form the tubular section, which is then used to construct seamless pipes. The lack of seam welds is referred to as seamless.

Within the oil and gas sector, seamless steel pipes are applied in a variety of ways

  • Operations upstream (OCTG pipes).
  • Midstream (transmission and distribution of fluids, such as oil, gas, steam, acids, and slurries).
  • Applications of general plumbing for utility services downstream (process pipework to refine oil and gas in derivative goods).

Some requirements, like ASTM A106, apply to both seamless and welded pipes, whereas others solely cover Carbon Steel Seamless Pipes (for example ASTM A53).

The majority of high- and low-temperature applications can be utilized for carbon steel pipes (A53, A333, A106, and API 5L), while corrosive services are the primary usage for stainless steel pipes, which have a smaller market share and higher grades are used as the temperature and the pressure increase, or when the conveyed fluid is more and more aggressive.

The primary specification for OCTG pipes in the upstream oil and gas sector is API 5CT (oil country tubular goods).

To avoid confusion, seamless tubes and steel pipes must be distinguished. Tubing and pipes do differ in a few significant ways that go beyond simple lexical distinctions. In general, a Carbon Steel Seamless Pipes or tube is a tube or tube section used in transporting fluids, while a tube or section used in the construction of pressure equipment such as boilers and heat exchangers is a tube or section of various shapes and sizes.

ERW pipes

Steel coils are used to make ERW pipes; the coil is first uncoiled, followed by smoothing, cutting, and ultimately, electrically attaching its two ends to form a pipe.

Due to the advanced welding techniques used by ERW pipe producers, ERW pipes have recently emerged as a cost- and performance-effective alternative to seamless pipes (example HFI and HFW, high-frequency welding). As a result of these developments in welding technology, seamless and ERW pipes are now interchangeable, at least in some low- to medium-pressure and temperature applications, which has decreased the technical superiority of ERW pipes over seamless pipes over time. Naturally, seamless pipes will always benefit from the steel billets’ inherent better mechanical strength over coils and plates.


Steel coils are first uncoiled, cut, processed, welded, and tested. For oil and gas pipes, the “high-frequency induction technology” (ERW-HFI), with its induction current applied to the outside surface of the pipe, is the most frequently used welding method.

  • In comparison with cast iron, die casting techniques enable them to be shaped into complicated shapes without sacrificing strength or durability due to their lighter density i.e., lighter than cast iron.

Seamless and Welded Stainless Steel Pipes: What’s the Difference?

What are Pipes Exactly?

Water is transported through pipes, and sewage is carried through them, as well as gas is transported through pipes, although it is less efficient than other forms of piping, such as steel pipes. The pipes are used in many applications, including plumbing, oil and gas pipelines, and irrigation systems. The pipes typically have two ends, one at each end of the tube that is connected or piped together in some manner. Metal pipes (copper or steel pipes) are commonly used, but plastic pipes or other materials can also be used.

Welded Pipes

Stainless steel welded pipes are made by rolling the stainless steel sheet and welding process. Spot-welded pipes fall into four categories, welded pipes, spiral welded pipes, arc welded pipes, and pipes with straight seams.

Seamless Pipes

Seamless stainless steel pipes have a hollow cross-section and no seams, have inconsistent wall thicknesses, and lack quality of brightness both on the inside and outside. There are a number of complicated processes used to produce seamless tubes, starting with drilling holes in billets, followed by drawing, drawing, and rolling after cold drawing.

The Difference among Seamless and Welded Stainless Steel Pipes

Surface finishing is original

An original surface of welded stainless steel pipe is superior to a seamless steel pipe. The faults in the exterior surface of a hot-rolled billet cannot be corrected during the hot rolling process; they can only be corrected after the seamless pipe has been fabricated. The removal of superficial flaws is complicated. Once the finished product is ready for processing, the flaws can be removed.

The grade that was used

Stainless Steel 304 Welded Pipes are considered to be the most common grade of pipes. 316 type welded stainless steel pipe is rare since it is more expensive than 304. In the petrochemical, compressor machinery, heating, and boiler industry, seamless stainless steel pipes are primarily used in grades 304 and 316, which have higher pressure capacities and greater strength.

Differences in thickness and size

Pipes made of welded stainless steel have thinner and more uniform walls. Stainless steel seamless pipes have thick, heavy walls.

Price and Cost

There is a lower price difference between seamless and welded stainless steel pipes, and welded stainless steel pipes are generally available in highly uniform lengths.


Seamless pipes can usually be used when low-pressure applications or when flexibility is required, such as in gas lines, since stainless steel welded pipes can handle greater pressures without bursting. Welded stainless steel pipes are commonly used in high-pressure applications where they can handle greater pressures without bursting.
