Tube and pipe are manufactured in both carbon steel and stainless steel. The significant differences when considering which one is right for your application or project are important:
- Tube is calculated by outside (OD) diameter and wall thickness, pipe is calculated by their nominal pipe size (NPS) and schedule (wall thickness).
- Pipe is round and is used to distribute fluids and gases.
- Tube is round, square or rectangular.
- Steel tube is often used for smaller diameters where tight tolerances are needed, while steel pipe is well suited for large applications.
- Due to the manufacturing process, steel pipe is more cost-effective than steel tube since they require less processing and inspection.
Steel Tube Characteristics
Available in seamless or welded options, steel tube is well-suited for structural applications. As a versatile metal profile, steel tube provides the strength and durability needed for a wide range of industrial and commercial uses. Material options include mild carbon steel tubing as well as stainless steel tubing.Often manufactured in square, round, or rectangular (flat) hollow profiles, steel tubing offers you the following benefits:
- Can be telescoped
- Cost-efficient
- High tensile strength
Common industrial applications for steel tubing include:Applications for Steel Tubing
- Construction
- Automotive applications
- HVAC applications
- Medical device components
Steel Pipe Characteristics
Similar to steel tubing, steel piping is widely used for manufacturing and industrial purposes. Also available in seamless or welded options, steel pipe is readily available in carbon steel or alloy steel material options. To assist with corrosion resistance, steel pipe can also be galvanized with a protective coating. Carbon steel pipe is easily workable, making it suitable for general purpose applications. Stainless steel pipe is often used for gas or liquid transport or where its sanitary, hygienic properties are needed.Applications for Steel Pipe
Industrial and manufacturing uses for steel pipe include:- Chemical applications
- Oil and gas applications
- Heat exchangers
- Plumbing applications
- Automotive hydraulics
