（1) Ferritic alloy cold worked steel pipes should be free of scaling and suitable for inspection. Installation with slight oxidation should not consider scaling.
(2) Ferritic alloy hot worked steel pipes should be free of loose scale and suitable for inspection.LSAW Steel Pipe
(3) Stainless steel pipes should be picked without scale, and when using bright annealing, there is no need for acid washing.
(4) Any special surface treatment requirements should be agreed upon between the supplier and purchaser
