What is the difference between Alloy Steel Pipe and Tube?

Although pipes and tubes may look similar, they are in fact quite different in nomenclature and sizing. Remember that pipes and tubes are rarely interchangeable. The difference between pipe and tube include:

  • Shape – Pipes are always round, whereas tubes can be square, rectangular or round.
  • Tolerances – Pipe tolerances are set but not too restrictive. Tube tolerances are very strict – (Production process is generally lengthy and involves many quality checks around key dimensional parameters such as straightness, roundness, wall thickness, surface, etc.).
  • Measurement – Pipes are generally measured by the inside diameter (ID), often called the “nominal” diameter, and a “schedule”, which refers to the wall thickness whereas for tubes, the outer diameter (OD) and wall thickness, which are exact measures in inches or millimeters roughly corresponds to the tube size. For tubes, the difference between the outside diameter and the wall thickness, multiplied by two, defines the inside diameter of the tube.
  • Telescoping Abilities – Tube can be telescoped. Pipe, on the other hand, does not have a flash weld. DOM (Drawn over Mandrel) Tube is the best material for telescoping because the inside flash weld has been removed.
  • Rigidity – Although copper and brass tubes can be shaped relatively easily, tubes are are typically rigid. Pipes, on the other hand, are invariably rigid and cannot be shaped without special equipment.
  • Applications – Pipes are used in all process fluids and services. Tubes are generally used in tracing lines, tubes for heat exchanger, fired heater and in instrument connection. Tubes are also used as primary load bearing member in steel structure for the civil application.
  • Metal Types – Tube is available in hot rolled steel and cold rolled steel. Pipe is typically black steel (hot rolled). Both items can be galvanized.
  • Size – Pipes are typically larger than tubes.
  • Strength – Tubes are stronger than pipes.

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.

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.

How are Steel Pipes Certified?

Certification of Steel Pipes

Manufacturers issue a Material Test Report or Mill Test Report to validate that the product meets the chemical analysis and mechanical properties specification. The MTR will contain all relevant data to the product and will accompany the product through its lifecycle.

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
