What is the difference between galvanized pipe and black pipe

In view of this, transport gas by galvanized pipes is dangerous so it is often used in carrying water. Black steel pipe, on the other hand, is not suitable for water transport. Black steel pipes are tending to corrode in water and mineral of the pipe will dissolve into the water and clog the line as well. General speaking, black steel pipe is cheaper than galvanized pipe.

This is due to the zinc coating on galvanized pipe and the manufacturing process making it. Black steel pipe is low maintenance; it costs less to the fitting. Black steel pipe and galvanized steel pipe looked similar in the eye of many people. So how to differentiate this two pipe? Water and gas require pipes to supply residential homes and businesses. Gas supplies power to stoves, water heaters, furnaces and other devices.

Water is essential and obvious. The two most common types of steel pipe used to carry water and gas are black pipe and galvanized pipe. Confusion is common among home owners, and even some professionals, as to where to use these steel pipes and under what circumstances. Seamless Alloy Steel Tube. Welded Alloy Steel Pipe. Titanium Pipe. Stainless Steel Seamless Pipe. Stainless Steel Welded Pipe. Stainless Steel Plate.

Stainless Steel Coil. Hot Dip Galvanized Pipe. Pre Galvanized Steel Pipe. Galvanized Steel Coil. Hot Induction Bend. FBE Coated Pipe. Concrete Coated Pipe. Square Steel Tube. Rectangular Steel Tube.

The zinc increases the pipes life expectancy and makes it more resistant to corrosion and mineral deposits in the line.

It is a plumbing material that is used in water supply lines and has been used in homes for more than 30 years. It cannot be used for gas lines because the zinc can clog the lines when it begins to flake, but it has many other uses. It can also be used in outdoor railings, scaffolding, fence, sewage plumbing, and farm irrigation and it is best used for bigger construction projects and has a life expectancy of 40 years.

Although the zinc that coats galvanized pipe can prevent corrosion, it corrodes quicker than copper or PVC pipes. Aside from this, it contains lead which can be harmful. It is also more expensive than black pipe. The flaking of the zinc in galvanized pipes can cause pipes to burst. While there are now safer and stronger pipes made from materials other than steel, black pipes and galvanized pipes are still very popular and are being used in homes and buildings. The thing to remember is to use them according to the specifications of the project and to use only one type of pipe in conveying water or gas to your homes.

It is not advised to combine two types of piping material. Summary 1. Black pipe is made of steel as is galvanized pipe.

The difference is that galvanized pipe is coated with zinc, while black pipe is not. Black pipe is best used for gas lines, not for water lines because it rusts easily, while galvanized pipe is the safer pipe to use in water lines, but it cannot be used to convey gas.

Black pipe is cheaper than galvanized pipe because of the zinc that is added to galvanized pipe. Difference Between Black and Galvanized Pipe.
