Description
Schedule 40 Steel Pipe is a commonly used wall thickness grade in American Standard piping systems. It has clear pressure standards and application specifications and is widely used in industries such as the petroleum and chemical industries. SCH40 Steel Pipe is available in welded steel pipe, seamless steel tubes, and galvanized steel pipes versions, depending on the production standards and intended use.
Schedule 40 Steel Pipe represents medium-wall steel pipe, with outer diameters ranging from 1/8″ to 32″, or 10.3mm to 813mm, and wall thicknesses from 1.73mm to 17.48mm.
Schedule 40 Steel Pipe has a wide range of applications:
Common Materials: Carbon steel, stainless steel, and other steel pipes may all feature SCH40 wall thickness.
Typical Applications: Medium-pressure applications such as building water supply and drainage, and industrial fluid transportation.
Features: It offers both pressure resistance and cost-effectiveness, making it a highly versatile choice.

Applications of Schedule 40 Steel Pipe:
Schedule 40 Steel Pipe is a seamless/welded carbon steel pipes or stainless steel pipe of American standard wall thickness. It is primarily used for medium- and low-pressure fluid transport and general structural support. It is not suitable for ultra-high pressure or extreme corrosive/low-temperature environments.
1. Fluid Transport: Schedule 40 Steel Pipe is widely used in industrial piping systems for oil, natural gas, water, steam, compressed air, and chemical media (non-strongly corrosive). For DN ≤ 250 mm, it is equivalent to a “Standard Weight Pipe (STD)”.
2. Mechanical Structural Components: Schedule 40 Steel Pipe is used to manufacture non-pressure-bearing components requiring certain strength and bending stiffness, such as supports, frames, hydraulic supports, and drive shafts.
3. Buildings and Infrastructure: Schedule 40 Steel Pipe is suitable for scaffolding, guardrails, bridge components, and general building steel structures (non-critical load-bearing parts).
4. Boilers and Heat Exchange Systems: Schedule 40 Steel Pipe is used in medium and low-pressure boiler water pipes, condensers, or heaters (requires matching materials such as ASTM A106 Gr.B or A53 Gr.B).
5. Shipbuilding and Offshore Platforms: Schedule 40 Steel Pipe is used for medium-pressure auxiliary pipelines such as bilge pump pipes and ballast water systems (often requiring additional corrosion protection).
