DIMENSIONAL TABLES

Product catalog summary

Overview: This document provides dimensional tables for welded and seamless tubes, specifying outer diameter (O.D.), wall thickness (W.T.), and mass. It includes tolerances for delivery conditions marked as +SR.

Specifications:

Welded Tubes: O.D. up to 230 mm, W.T. up to 12.5 mm.
Seamless Tubes: O.D. up to 380 mm, W.T. up to 25 mm.

Tolerances:

The tolerances on the outer diameter (O.D.) are specified for various nominal sizes and are crucial for ensuring the tubes meet delivery conditions.
Inner diameter (I.D.) tolerances are not standardized and require special agreements with manufacturers, making them approximate.

Dimensional Data:

Tables provide nominal and tolerance values for O.D., W.T., and mass (Kg/m) for different tube sizes.
Examples include:
- For a nominal I.D. of 20 mm, O.D. tolerance is ±0.08 mm, W.T. is 5 mm, and mass is 3.08 Kg/m.
- For a nominal I.D. of 50 mm, O.D. tolerance is ±0.25 mm, W.T. is 5 mm, and mass is 6.94 Kg/m.

Notes:

The document emphasizes that I.D. tolerances are not governed by norms and are subject to manufacturer agreements.
