Black Iron (BI) Pipes

Black Iron (BI) Pipes For Sale Philippines

Black Iron Pipes refers only to the surface treatment of the pipes, whereas it is treated or coated with black paint. It is applicable only to carbon steel pipes.

“Black iron” is a term that usually refers to a type of black-coated steel, but many different types of black iron pipe exist. The main problem with this is that there are few standards that all black iron pipes adhere to. However, they are all made to handle natural and propane gas, which usually stay below 60 PSI.

Black Iron Pipes are made of steel that has not been galvanized. Its name comes from the scaly, dark-colored iron oxide coating on its surface that prevents rust. Black steel pipes are cut and threaded to fit.

• Used for pipes in oil and petroleum industries
• For water, gas and sewerage purposes
• Low-pressure hot water heating pipes
• Water wells and pipes for various automotive and industrial applications

The primary purpose of black steel pipe is to carry natural gas into homes and businesses. The pipe is manufactured without a seam, making it a stronger and safer pipe to carry gas.

The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe.

What are the advantages of Black Iron Pipes?

Strength & Durability:

High Carbon Steel Construction: Black iron pipes (BI pipes) are made from hot-rolled or cold-rolled carbon steel. This construction material offers exceptional strength and can withstand high pressure and heavy loads. This makes them ideal for critical applications like plumbing and gas lines of buildings.

Resistance to Bending and Cracking: The Black Iron Pipes’ robust construction makes them less prone to bending, cracking, or breaking than some plastic alternatives. This ensures reliable performance and minimizes the risk of leaks or structural failure in buildings.

Corrosion Resistance:

Iron Oxide Coating: Black iron pipes develop a natural rust layer during manufacturing. This offers some corrosion protection especially in places without moisture. For wetter environments, galvanized pipes provide overall better protection.

Affordability:

Cost-Effective Material: Compared to other options like copper or stainless steel, black iron pipes are a more affordable choice. This makes them a good value proposition for many plumbing and gas line applications, especially in larger construction projects.

Versatility:

Wide Range of Applications: Black iron pipes are not limited to just plumbing and gas lines as they can be used in various applications, including fire sprinkler systems, compressed air systems, and even for structural purposes due to their sturdiness.

Easy to Thread and Connect: Black iron pipes are relatively easy to thread and connect using standard pipe fittings. This allows for a secure and reliable connection, thereby simplifying pipe installation.

Fire Resistance:

High Melting Point: Black iron pipes excel in fire resistance. Their high steel melting point makes them ideal for fire sprinkler systems, helping contain fires and safeguard property.

While black iron pipes boast strength, durability, and affordability, they are susceptible to rust in damp environments and can be heavier than plastic alternatives. However, their numerous advantages often outweigh these limitations, making them a popular choice in construction.
