The NBR 5590 Standard fixes the required conditions for ordering, manufacturing and supplying carbon steel tubes, with seam or non-seam tubes, black or galvanized for conduction of fluids, and under pressure, mechanical applications, being also oil for use in lines of steam, water, gas, and compressed air.
The tubes manufactured according to this Standard are classified in:
Normal – N;
Reinforced – R;
Double Reinforced – DR.
And it can be two types:
Type E: welded by electrical resistance, grades: A and B;
Type S: sem seam, nos graus: A e B.
The tubes, according to NBR 5590, are designated by nominal diameter (NPS), class, type and grade of steel.
