1 1/2 Black Iron Pipe

The raw material of 1 1/2 black iron pipe is carbon steel such as Q235B, which has good welding performance and strength and low cost. However, because its surface is prone to rust, the anti-corrosion coating on the surface should be checked regularly. It is more common in some scenes with low corrosion requirements, such as temporary support in building structures, non-drinking water supply systems with low water quality requirements, and can be used to transport gases such as hydrogen and nitrogen in chemical production.
