1- 2 Inch Black Iron Pipe Vs Galvanized Pipe

Contents
erw carbon steel pipe

What is black iron pipe? Black iron pipe is a pipe made of ordinary carbon steel as the main material. The seamless steel pipe is hot rolled or cold rolled on the surface to travel a layer of iron oxide, so it is named.

Black iron pipe and its fittings have become an indispensable part of the pipeline system with their unique physical properties, wide range of applications, and reasonable price and cost, guaranteeing the safe and efficient operation of the pipeline system.

Black Iron Pipe and Fittings Types/Function

Black iron pipe and fittings are the key parts responsible for connecting pipes, changing the direction of pipes, branching or controlling fluid flow.

There are several types of common black iron pipe fittings.

Difference Between Black Iron Pipe Vs Galvanized Pipe

Black Iron Pipe Vs Galvanized Pipe Material/Characteristics

  • The black iron pipe is not galvanized and is made of carbon steel. With high strength, corrosion resistance, good thermal conductivity and other mechanical properties. Although the surface is prone to rust, its corrosion rate is relatively slow when the internal fluid is not in direct contact with the air. It is often used in fire sprinkler systems and high-pressure fluid transmission.
  • Galvanized pipes can be galvanized on the surface of steel pipes by hot dip plating, electroplating and mechanical galvanizing. The zinc layer can effectively isolate the direct contact between the steel pipe and the corrosive medium such as air and water. So galvanized pipe has excellent corrosion resistance. It is widely used in oil, drainage and other fields.

How To Use Black Iron Pipe Vs Galvanized Pipe

There are some precautions when using these two pipes.

  • Black iron pipes need to be maintained by coating anti-corrosion coatings and installing anti-corrosion sleeves in a humid and corrosive environment.
    • The toughness is poor, so avoid impact during use, so as to avoid rupture or deformation.
  • Galvanized pipe is prone to thermal expansion and deformation under high temperature environment, so it is necessary to control its temperature range.
    • The chemical composition of the water can react with zinc, causing the zinc coating to fall off or produce harmful substances. Water quality needs to be adequately assessed.

Black Iron Pipe Conclusion

Black iron pipe has many advantages such as high strength, excellent thermal conductivity, but poor corrosion resistance, need to take corresponding anti-corrosion measures and follow-up maintenance work.

Select the right pipe and carefully and scientifically maintain it, give full play to the advantages of black iron pipe, and provide power for the stable operation of the pipeline system.
