Zeitplan 40 schwarzes Stahlrohr


Zeitplan 40 black steel pipe is a type of carbon steel pipe used in a variety of applications. Der “Zeitplan” number in pipe specifications refers to the thickness of the pipe wall, with higher numbers indicating a thicker wall. Here’s an overview of the characteristics and uses of Schedule 40 schwarzes Stahlrohr:



  • Wandstärke: For Schedule 40, the wall thickness varies based on the diameter of the pipe. The wall thickness is more than sufficient for most high-pressure applications.
  • Material: The pipe is made from carbon steel, which provides good strength and can be welded or fabricated with the right techniques and equipment.
  • Finish: Der “Schwarz” in black steel refers to the protective coating on the steel to prevent rust. This is achieved through a black oxide scale that forms on the surface of the steel during the hot fabrication process.
  • Haltbarkeit: Zeitplan 40 black steel pipes are durable and designed to withstand high pressures and temperatures.
  • Durchmesser: The nominal pipe size can range from very small to several feet in diameter. Jedoch, for most practical uses, common diameters are from 1/8 Zoll zu 24 Zoll.


  • Installation: Widely used for transporting water, Gas, air, and steam, as the schedule 40 thickness provides a good balance of strength and weight.
  • Structural Applications: Because of its strength, it can be used in structural applications such as handrails, Gerüst, and support columns.
  • Industrial: Used in process industries for conveying fluids under high pressure and temperature.
  • Fire Protection Systems: Often used for piping fire sprinkler systems due to its durability and resistance to heat.
  • Öl-und Gasindustrie: Zeitplan 40 pipes are used for some oil and gas applications due to their ability to withstand hohe Drücke.

Installation Considerations:

  • Schweißen: Black steel pipe is generally joined by welding. It requires proper technique and precautions to ensure a strong and safe connection.
  • Einfädeln: These pipes can also be connected using threaded connections, where the pipes are threaded on the ends and joined with fittings.
  • Korrosionsschutz: Although the black oxide helps prevent rust, it is not a substitute for proper corrosion protection in corrosive environments. Additional coatings or paint may be applied depending on the usage conditions.
  • Code Compliance: Always ensure that any use of Schedule 40 black steel pipe complies with local building codes and standards for the application in question.

When purchasing or specifying Schedule 40 schwarzes Stahlrohr, it’s important to verify the exact specifications, such as the diameter, Wandstärke, Länge, and any additional treatments needed for the intended application. Suppliers typically provide pipes in pre-cut lengths or custom cut to specifications.

    What is the difference between SCH 40 and SCH 40S?

    • Ronsun2023

      daher, the difference between SCH 40 and SCH 40S is the wall thickness, with SCH 40 being thicker and suitable for standard steel pipe applications, while SCH 40S is thinner and specifically designed for stainless steel pipes.

      The main purpose of sch 40 black steel pipes is to transport propane or natural gas to residential and commercial buildings. The pipeline has no seams, making it a better pipeline for carrying gas. Black steel pipes are also used for fire sprinkler systems.
