Can you use black steel pipe for water？
Black steel pipe is made from uncoated carbon steel and is mainly used to transport gas or air rather than water. While it is strong and affordable, it is not recommended for water supply systems because the lack of a protective coating makes it prone to rust and corrosion when exposed to moisture. Over time, rust buildup can contaminate the water and cause blockages inside the pipe.
Black steel pipes are commonly used in fire sprinkler systems, natural gas pipelines, and industrial air lines where water is not constantly present. For water supply or plumbing applications, galvanized steel pipes or stainless steel pipes are much better choices since they provide a zinc or chromium protective layer that prevents corrosion and ensures clean water flow.
Yuantai Derun’s galvanized steel pipes are specially coated to resist rust and deliver safe, long-lasting performance for both industrial and residential water systems, making them a reliable alternative to black steel pipes in wet environments.
