Difference Between Seamless and Welded Alloy 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 Process of Alloy Steel Pipe

Seamless Pipes Manufacturing Process:

  1. Mandrel Mill Process
  2. Mannesmann Plug Mill Pipe Manufacturing Process
  3. Forged Seamless Pipe Manufacturing Process
  4. Extrusion Processes

They are explained below:-

  1. Mandrel Mill Process: – In the Mandrel Mill Process, a solid round (billet) is used. It is heated in a rotary hearth heating furnace and then pierced by a piercer. The pierced billet or hollow shell is rolled by a mandrel mill to reduce the outside diameter and wall thickness which forms a multiple length mother tube. The mother tube is reheated and further reduced to specified dimensions by the stretch reducer. The tube is then cooled, cut, straightened and subjected to finishing and inspection processes before shipment.
  2. Mannesmann Plug Mill Process: – In the Plug Mill Process, a solid round (billet) is used. It is uniformly heated in the rotary hearth heating furnace and then pierced by a Mannesmann piercer. The pierced billet or hollow shell is roll reduced in outside diameter and wall thickness. The rolled tube simultaneously burnished inside and outside by a reeling machine. The reeled tube is then sized by a sizing mill to the specified dimensions. From this step the tube goes through the straightener. This process completes the hot working of the tube. The tube (referred to as a mother tube) after finishing and inspection, becomes a finished product.
  3. Forged Seamless Pipe Manufacturing Process: – Steel Products may be manufactured either by casting or forging steel. Forged Seamless Pipe Manufacturing Process implies the application of mechanical forces to heated solid blocks of steel (such as ingots and/or billets) that are shaped into desired products permanently. They require the application of high temperatures to steel raw materials (to liquefy or make it malleable).Once this forging is done, pipe is machined to achieve final dimension. Forged pipes are generally used for the steam header. This process is used to manufacture large diameter seamless pipe that cannot be manufactured using traditional methods.
  4. Extrusion Processes: – Metal extrusion is a metal forming process in which a work piece, of a certain length and cross section, is forced to flow through a die of a smaller cross sectional area, thus forming the work to the new cross section. The length of the extruded part will vary, dependent upon the amount of material in the work piece and the profile extruded. Numerous cross sections are manufactured by this method. The cross section produced will be uniform over the entire length of the metal extrusion. Starting work is usually a round billet, which may be formed into a round part of smaller diameter, a hollow tube, or some other profile.  Metal extrusion is a forming process, like other metal forming processes; it can be performed either hot or cold.

Effects of Alloying Elements on Steel

•Manganese – strength and hardness; decreases ductility and weldability; effects hardenability of steel.
•Phosphorus – increases strength and hardness and decreases ductility and notch impact toughness of steel.
•Sulfur decreases ductility and notch impact toughness Weldability decreases. Found in the form of sulfide inclusions.
•Silicon – one of the principal deoxidizers used in steel making. In low-carbon steels, silicon is generally detrimental to surface quality.
•Copper – detrimental to hot-working steels; beneficial to corrosion resistance (Cu>0.20%).
•Nickel – ferrite strengthener; increases the hardenability and impact strength of steels.
•Molybdenum –  increases the hardenability; enhances the creep resistance of low-alloy steels.

What are the Steel Pipe Sizes?

Steel pipe sizes

Pipe size is quoted as a “Nominal Pipe Size” or NPS. The origin of the NPS numbers for smaller pipes (< NPS 12) is different to the origin for larger diameter pipes. However, all pipes of a specific NPS number have the same external or outer diameter (OD). The internal diameter will vary depending on the wall thickness of the metal. The reason for this is so that the same structural supports can be used for all piping of a specific NPS number regardless of the wall thickness.

Schedules

Steel pipe schedules are a way to describe the wall thickness of the pipe. This is a critical parameter as it is directly related to the strength of the pipe and the suitability for specific applications. A pipe schedule is a dimensionless number and is calculated based on the design formula for wall thickness, given the design pressure and allowable stress.

Examples of schedule numbers are as follows: 5, 5S, 10, 20, 30, 40, 50, 60, 80, 100, 120, 140, 160, STD, XS, and XXS—with the most common being schedules 40 and 80. As the schedule number increases, the wall thickness of the pipe increases. The schedule number of a pipe therefore defines the internal diameter, as the OD is fixed by the NPS number.

The following are typical parameters that may be recorded on an MTR:

  • Chemical composition including carbon content, alloys, and sulfur
  • Material size, weight, identification, and grade
  • Material heat number, which ties back to the processing batch
  • Mechanical properties like tensile strength, yield strength, and elongation
