Mild steel black pipes

Mild steel black pipes

Mild steel black pipes refers to a pipe made of mild carbon steel, the carbon content is generally 0.05%-0.25%, and its surface forms a black oxide coating during the manufacturing process, providing it with a certain corrosion resistance. They are commonly used for water supply, plumbing, fire fighting, HVAC, etc. They can also be used in a variety of other industrial and engineering applications. These pipes are usually coated with metal, paint, etc., to prevent rust.

Main features:
Low carbon content, it has better ductility, weldability and is relatively soft compared to high carbon steel.
High weldability: Low carbon steel is easy to weld and can be molded into different shapes, suitable for manufacturing and construction.
High strength, good durability: Low carbon steel has enough strength to be used for general purposes such as structural support or fluid transport, but the strength is not as strong as high carbon steel.
Corrosion resistance: Due to its special manufacturing process, a black oxide layer is formed on its surface, which can provide certain anti-rust protection.
Versatility: These pipes are available in a variety of sizes and thicknesses for use in construction, plumbing and manufacturing.

Disadvantages: 

The tensile strength of low carbon steel black tubes is lower than that of high carbon steel, which limits its use in higher stress situations

. Although it has a black oxide layer on its surface, it provides limited protection and is not enough to cope with more corrosive environments without further treatment.

Application place:
Water and gas delivery: Commonly used in gas and low pressure water systems, such as household plumbing and heating.
Structural applications: mainly used in the construction of building frames, columns and other structural components.
Mechanical and general engineering: The manufacture of machines, parts and components for various industries.
Conduits: In electrical installations, mild steel black tubes can be used as conduits for electrical wires.

In summary:
Mild steel black tubes are a versatile and affordable choice in many industries, especially in low-pressure fluid transport, structural applications, and general construction. Although they have good durability and are easy to manufacture, they are not suitable for more corrosive environments unless appropriate protection measures are taken.
