Surface Condition
Ferritic alloy cold-finished steel tubes shall be free of scale and suitable for inspection. A slight amount of oxidation is not considered scale.
Ferritic alloy hot-finished steel tubes shall be free of loose scale and suitable for inspection.
Stainless steel tubes shall be pickled free of scale. When bright annealing is used, pickling is not necessary.
Any special finish requirement shall be subject to agreement between the supplier and the purchaser.
