What are the Differences between Black Pipe and Galvanized Pipe?

What is the difference between black pipe and galvanized pipe?

Black pipe: welded steel pipe for low-pressure fluid transmission is also known as general welded pipe, commonly known as black pipe. It is a welded steel pipe used for conveying water, gas, air, oil, heating steam and other low pressure fluids and other purposes. The joint wall thickness of steel pipe is divided into ordinary steel pipe and thickened steel pipe; the nozzle end is divided into unthreaded steel pipe (plain pipe) and threaded steel pipe.

The specification of steel pipe is indicated by nominal diameter (mm), which is the approximate value of inner diameter. It's usually expressed in inches. The welded steel pipe for low-pressure fluid transportation is not only used to transport fluid directly, but also used as the original pipe of galvanized welded steel pipe for low-pressure fluid transportation.

Galvanized pipe: galvanized welded steel pipe for low-pressure fluid transmission is also called galvanized pipe, commonly known as white pipe. It is a hot-dip galvanized welded (furnace welding or electric welding) steel pipe used for conveying water, gas, air oil, heating steam, warm water and other general lower pressure fluid or other purposes.

The joint wall thickness of steel pipe is divided into ordinary galvanized steel pipe and thickened galvanized steel pipe; the connection end is divided into unthreaded galvanized steel pipe and threaded galvanized steel pipe. The specification of steel pipe is indicated by nominal diameter (mm), which is the approximate value of inner diameter, which is usually expressed in inches.
