Lịch trình 40 black steel pipe is a type of carbon steel pipe used in a variety of applications. Các “lịch trình” 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 ống thép đen:

 

Characteristics:

  • Độ dày của tường: 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.
  • Vật liệu: The pipe is made from carbon steel, which provides good strength and can be welded or fabricated with the right techniques and equipment.
  • Finish: Các “đen” 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.
  • Độ bền: Lịch trình 40 black steel pipes are durable and designed to withstand high pressures and temperatures.
  • Đường kính: The nominal pipe size can range from very small to several feet in diameter. Tuy nhiên, for most practical uses, common diameters are from 1/8 inch đến 24 inch.

Công dụng:

  • Hệ thống nước: Widely used for transporting water, khí, 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, đoạn đầu đài, 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.
  • Ngành công nghiệp dầu mỏ và khí đốt: Lịch trình 40 pipes are used for some oil and gas applications due to their ability to withstand áp lực cao.

Installation Considerations:

  • Hàn: Black steel pipe is generally joined by welding. It requires proper technique and precautions to ensure a strong and safe connection.
  • Luồng: These pipes can also be connected using threaded connections, where the pipes are threaded on the ends and joined with fittings.
  • Bảo vệ chống ăn mòn: 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 ống thép đen, it’s important to verify the exact specifications, such as the diameter, độ dày của tường, chiều dài, and any additional treatments needed for the intended application. Suppliers typically provide pipes in pre-cut lengths or custom cut to specifications.

      Lịch trình 40 steel pipe makes sturdy and attractive curtain rods, shelves, coat hooks, floor lamps, and magazine racks. Of course, lịch trình 40 pipe’s primary application is transporting high-temperature, high-pressure liquids for commercial and residential properties in the oil and gas industry

      Vì thế, 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.
