Black Steel Pipe VS Galvanized Pipe Fittings

by | Apr 27, 2023 | News

When it comes to plumbing pipes, black steel pipes and galvanized steel pipes are two of the options often used for water supply lines and other applications. Both types of pipe are made of steel. However, galvanized pipe has a zinc coating to prevent corrosion, while black steel pipe has a dark color from the manufacturing process.

Introduction to Galvanized Pipe Fittings

Galvanized pipe is coated with zinc, which reacts with oxygen to form a coating that prevents further rusting. Black steel pipe has no coating, so it can rust over time when exposed to moisture. However, black steel pipe is also more durable and can handle higher pressure than galvanized pipe. Black steel pipe is also cheaper than galvanized pipe and can last up to 50-100 years with proper maintenance.

Galvanized pipe fittings are suitable for applications like plumbing hot and cold water supply lines. The zinc coating helps prevent rusting and corrosion. Then it makes a good solution for high-moisture environments. However, galvanized pipe corrodes over time and can release small traces of lead. It has a lifespan of 25-50 years, depending on the water conditions. Galvanized pipe is also more expensive than black steel pipe.

Black Malleable Iron Pipe Fittings

Black malleable iron pipe fittings are a type of plumbing fitting. They are made from malleable iron. Moreover, it is a type of cast iron that has been treated with heat and other processes to make it more malleable and ductile. Actually, black malleable iron pipe fittings are as matched as black steel pipe. This means that it can be easily shaped and molded into different forms without breaking or cracking.

One of the main advantages of black malleable iron pipe fittings is their strength and durability. They are designed to withstand high pressures and temperatures, which makes them a popular choice for industrial and commercial plumbing systems. They are also resistant to corrosion and rust, which means they can last for many years without needing to be replaced.

Another advantage of black malleable iron pipe fittings is their versatility. They can be used in a wide range of plumbing applications, including water and gas pipelines, air conditioning systems, and steam heating systems. They are also compatible with a variety of different pipe materials, including copper, PVC, and galvanized steel.

Conclusion of Both Black Steel Pipe and Galvanized

In the end, both black steel pipe and galvanized pipe have pros and cons for different applications. For most residential plumbing, galvanized pipe is a good choice due to its resistance to corrosion. But for industrial plumbing where higher pressure is involved, black steel pipe may be more suitable. The choice also depends on factors like cost, longevity, and safety requirements for your specific plumbing project.
