Schedule 40 Steel Pipe
SCH 40 Steel Pipe
SCH 40 steel pipes are medium-walled pipes commonly used in a variety of industries, particularly in low to medium-pressure environments. They are widely applied in water pipelines, construction structures, and the oil and gas industry. Known for their good pressure resistance and corrosion resistance, SCH 40 pipes are a popular choice for fluid transportation and structural applications.
