Product catalog summary
Cold Drawn Seamless Tubes in Steel E 235

Specifications:
The document provides detailed specifications for cold drawn seamless tubes made from steel E 235. These tubes are available in various dimensions and are characterized by their external diameter, thickness, weight per meter, working pressure, and burst pressure. The tubes are categorized into different series, including the normal gas range and reinforced gas range, each with specific pressure ratings.

Procedures and Standards:
The tubes are manufactured following the NFA 49112 standard, ensuring they are seamless, hot rolled, scoured, oiled, and obturated. The document also mentions compliance with ISO 10763 for hydraulic and pneumatic circuits.

Delivery State:
The tubes are delivered with oiled internal and external surfaces to protect against corrosion during transport and storage. The surfaces are smooth with a maximum roughness of Ra ≤ 4 μm. Tube ends are cut perpendicular to the axis and are free of burrs, sealed with plastic plugs.

Marking and Packaging:
Normydro tubes are marked longitudinally with the logo, grade, standard, dimensions, manufacturing date, and casting number. Standard tube lengths are 6.00 meters, with deliveries made in hoop-bound bunches, each dimension separately bound.

Bending:
The tubes can be bent to a minimum radius of 2.5 times the diameter.

Key Data from Tables:
The tables provide a comprehensive list of tube dimensions, weights, and pressure ratings. For example, the TA 8 x 13 tube has an external diameter of 13.25 mm, a thickness of 2.25 mm, a weight of 0.610 kg/m, a working pressure of 373 bars, and a burst pressure of 1494 bars. The reinforced gas range offers higher pressure ratings, such as the TAR 8 x 13 with a working pressure of 518 bars and a burst pressure of 2073 bars.

Recommendations:
For specific thickness requirements ranging from 2 to 20 mm, consultation is advised. The document emphasizes the importance of proper storage conditions to maintain tube integrity.

Les surfaces extérieure et intérieur des tubes sont lisses, avec une rugosité Ra ≤ 4 μm. Les extrémités des tubes sont livrées coupées d’équerre par rapport à l’axe et exemptes de bavures. Extrémités affranchies et obturées par des bouchons en plastique.” Internal and external tube surfaces are oiled to protect them during carriage and for a more or less long storage under shelter, in undamp and non corrosive atmosphere. External and internal surfaces are smooth, with rugosity Ra ≤ 4 μm. Ends are cut perpendicular to the axe of tube without beard. Ends are croped and obturated with plastic plug. MARQUAGE (Marking) Les tubes Normydro sont marqués longitudinalement en reprenant les indiquations suivantes : le logo, la nuance, la norme, les dimensions, la date et l’origine de fabrication et le numéro de coulée. Normydro tubes have longitudinal marking, incuding origin, standard, dimensions, manufacturing date and number of casting.
