Pipes are cylindrical structures designed to transport various substances such as liquids, gases, powders, and pellets. They serve as conduits for conveying these materials, facilitating processes across industries like manufacturing, energy production, and infrastructure development.
The size of a pipe is mainly determined by two measurements: the outer diameter (OD) and the wall thickness (WT). By subtracting twice the wall thickness from the outer diameter, we get the inside diameter (ID) of the pipe. This inside diameter is important because it determines how much liquid the pipe can hold.
Tubes are hollow shapes like circles, squares, rectangles, or ovals. They're used in things like machinery, pressure systems, and measuring instruments. When we talk about tubes, we describe their size by how wide they are on the outside and how thick the walls are. We can measure these sizes in inches or millimeters.
When we talk about pipes, the two main measurements we care about are how wide it is on the outside (the outer diameter or OD) and how thick the walls are (the wall thickness or WT). If we subtract two times the wall thickness from the outer diameter, we get the inside diameter (ID) of the pipe. This inside diameter is important because it tells us how much liquid the pipe can hold.
Seamless pipes and tubes are types of cylindrical hollow structures used for conveying fluids, gases, or solids from one point to another in various industries such as oil and gas, petrochemical, chemical, power generation, automotive, and construction. The term "seamless" refers to the manufacturing process used to produce these pipes and tubes. seamless pipes and tubes offer superior performance and reliability in demanding industrial applications due to their seamless construction and high-quality materials.
Welded pipes and tubes are cylindrical hollow structures used for conveying fluids, gases, or solids from one point to another in various industries. Unlike seamless pipes and tubes, which are manufactured without any welded seams, welded pipes and tubes are created through a welding process that joins two pieces of metal along their length. Proper welding techniques, quality control measures, and material selection are essential for ensuring the integrity and durability of welded pipes and tubes.
ERW stands for Electric Resistance Welded. ERW pipes are a type of welded steel pipe that is formed by rolling steel coils or strips into a cylindrical shape and welding the edges together using high-frequency electrical resistance welding. ERW pipes offer a cost-effective and efficient solution for various piping needs, providing strength, durability, and reliability in a wide range of industrial applications. Proper quality control measures and adherence to standards are essential for ensuring the integrity and performance of ERW pipes.

| Pipe vs Tube | Steel Tubes | Steel Pipes |
|---|---|---|
| Key Dimensions | The most important dimensions for a steel tube are the outside diameter (OD) and the wall thickness (WT). These parameters are expressed in inches or millimeters and express the true dimensional value of the hollow section. | The most important dimensions for a pipe is the outer diameter (OD) together with the wall thickness (WT). OD minus 2 times WT (SCHEDULE) determine the inside diameter (ID) of a pipe, which determines the liquid capacity of the pipe. The NPS does not match the true diameter, it is a rough indication |
| Types of Pipes and Tubes | Round, rectangular, square, oval | Round only |
| Production range | A narrower range for tubing (up to 5 inches), larger for steel tubes for mechanical applications | Extensive (up to 80 inches and above) |
| Wall Thickness | The wall thickness of a steel tube is expressed in inches or millimeters. For tubing, the wall thickness is measured also with a gage nomenclature. | The thickness of a steel pipe is designated with a “Schedule” value (the most common are Sch. 40, Sch. STD., Sch. XS, Sch. XXS). Two pipes of different NPS and same schedule have different wall thicknesses in inches or millimeters. |
| Tolerances and strength | Steel tubes are produced to very strict tolerances. Tubulars undergo several dimensional quality checks, such as straightness, roundness, wall thickness, surface, during the manufacturing process. Mechanical strength is a major concern for tubes. | Tolerances are set, but rather loose. Strength is not the major concern. |
| Material | Tubing is available in carbon steel, low alloy, stainless steel, and nickel-alloys; steel tubes for mechanical applications are mostly of carbon steel | A wide range of materials is available |
| Production Process | Tubes manufacturing is more lengthy and laborious | Pipes are generally made to stock with highly automated and efficient processes, i.e. pipe mills produce on a continuous basis and feed distributors stock around the world. |
| Market Cost | Higher due to lower mills productivity per hour, and due to the stricter requirements in terms of tolerances and inspections | Relatively lower price per ton than steel tubes |
| End Connections | Threaded and grooved ends are available for quicker connections on site | The most common are beveled, plain and screwed ends |
