جدول 40 black steel pipe is a type of carbon steel pipe used in a variety of applications. ال “جدول” 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 أنابيب الصلب السوداء:
- سمك الحائط: 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.
- مادة: The pipe is made from carbon steel, which provides good strength and can be welded or fabricated with the right techniques and equipment.
- Finish: ال “أسود” 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.
- متانة: جدول 40 black steel pipes are durable and designed to withstand high pressures and temperatures.
- قطر الدائرة: The nominal pipe size can range from very small to several feet in diameter. لكن, for most practical uses, common diameters are from 1/8 بوصة ل 24 بوصة.
- السباكة: Widely used for transporting water, غاز, 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, السقالات, 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.
- صناعة النفط والغاز: جدول 40 pipes are used for some oil and gas applications due to their ability to withstand الضغوط العالية.

- لحام: Black steel pipe is generally joined by welding. It requires proper technique and precautions to ensure a strong and safe connection.
- خيوط: These pipes can also be connected using threaded connections, where the pipes are threaded on the ends and joined with fittings.
- الحماية من التآكل: 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 أنابيب الصلب السوداء, it’s important to verify the exact specifications, such as the diameter, سمك الحائط, طول, and any additional treatments needed for the intended application. Suppliers typically provide pipes in pre-cut lengths or custom cut to specifications.
