Black steel pipe. Bare steel pipe and fittings will rust in 4 hours after production or shot blast, if no surface coating. Rust is permeable to air and water, therefore the interior steel beneath a rust layer continues to corrode. Also surface rust is flaky and friable, providing no protection to the underlying steel. Surface coating is required to prevent and delay rust.
