Difference Between Seamless and Welded Carbon Steel Pipe. How to Identify Whether a Pipe is Seamless or Welded?
Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.
In Seamless pipe, there are no welding or joints and is manufactured from solid round billets. The seamless pipe is finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 26 inch OD. Applicable in for High-pressure applications such as Hydrocarbon Industries & Refineries, Oil & Gas Exploration & Drilling, Oil & Gas Transportation and Air and Hydraulic cylinders, Bearings, Boilers, Automobiles, etc.
ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24” OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge. It is mainly used for low/ medium pressure applications such as transportation of water / oil. Common sizes for ERW Steel Pipe range from 2 3/8 inch OD to 24 inch OD in a variety of lengths to over 100 feet. Surface finishes are available in bare and coated formats and processing can be handled on site to customer specifications.
How to identify whether the pipe is seamless or welded?
If it is ASTM A53,
Type S means seamless.
Type F is furnace but welded,
Type E is Electrical resist welded.
That is how. It is the easiest way to identify whether pipe is Seamless or ERW.

Manufacturing and Testing Requirements of Carbon Steel Pipe
(Click Here to Read More About Manufacturing Process of Welded Steel Pipes in our Blog Section)
| Heat Treatment | Hot-finished pipe need not be heat treated. Cold-drawn pipe shall be heat treated after the final cold draw pass at a temperature of 1200 °F (650 °C) or higher. |
| Process | Carbon steel and mild steel are manufactured in three stages: |
| 1. Primary steelmaking | |
| 2. Secondary steelmaking | |
| 3. Casting | |
| The steel shall be killed steel, with the primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining. If secondary melting, using electroslag remelting or vacuum-arc remelting is subsequently employed, the heat shall be defined as all of the ingots remelted from a single primary heat. | |
| Steel cast in ingots or strand cast is permissible. When steels of different grades are sequentially strand cast, identification of the resultant transition material is required. The producer shall remove the transition material by any established procedure that positively separates the grades. | |
| Surface Treatment | Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting, Hot dip galvanizing, Electrolytic galvanizing |
| Hydrostatic Testing | Inspection test pressures produce a stress in the pipe wall equal to 60% of specified minimum yield strength (SMYS) at room temperature. Maximum Pressures are not to exceed 2500 psi for NPS3 and must stay under 2800 psi for the larger sizes. Pressure is maintained for not less than 5 seconds. |
| Non-destructive Electric Test | The full body of each pipe shall be tested with a non-destructive electric test in accordance with Practice E 213, E 309, or E 570. |
| Mechanical Tests Specified | Tensile Test — NPS 8 and larger — either transverse or longitudinal acceptable smaller than NPS 8 — weighed in lots. |
| Larger sizes — by length. | |
| Flattening Test — NPS 2-1/2 and larger. | |
| Bending Test (Cold) — NPS 2 and under. |

Prices for Carbon Steel Welded Pipes
Prices for carbon steel welded pipes are directly co related to prices of the raw materials such as iron ore, metal scrap, chromium, nickel and various other alloying elements. The production cost of heat resistant stainless steel and nickel alloy plates is high as they contain high amount of nickel and chromium. Meanwhile, mild steel material is among the lowest cost steel available, followed by carbon steel, 400 series stainless steels, aluminium, alloy steel, and 300 series stainless steel. Special alloys such as titanium, Inconel, Monel and Hastelloy cost very high as the nickel, chromium and moly content is very high.
