What is a Boiler Tube?

Boiler steel pipes and tubes are most widely used for manufacturing water cooled wall panel, economizer, reheater, superheater and steam pipeline of boilers in the industry of petrochemical and power. Boiler pipes and tubes are often used in severe environments and are required to have high strength and superior corrosion resistance. The manufacturing process for seamless boiler steel tubes does not include any welding, due to which they are considered to be stronger and more reliable. Boiler steel tubes are suitable for withstanding pressure better than other types of pipes.

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.

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

At Metallica, we will Provide you with Original MTR’s for all Alloy Steel Pipe Products! We will Send Our Test Certificates, along with Quotation
