Quality control in metal tube production
Within the metal tube industry, quality control plays a key role in ensuring both product safety and compliance with international standards. Mechanical testing allows manufacturers to evaluate material performance under load conditions and continuously monitor production quality throughout the manufacturing process.
Among the most critical inspections are tensile tests, which are performed to determine the mechanical properties of metal tubes and assess their resistance to operating stresses.
Tensile testing of metal tubes: goals and key parameters
Tensile testing of tubes and tubular sections is carried out in accordance with ISO 6892 standards and is used to determine the main parameters required for material characterization.
The most important values include:
- tensile strength (Rm)
- yield strength (ReH / ReL)
- proof stress (Rp0.2)
- elongation at break
These parameters provide essential information on the elastic and plastic behavior of the material, help identify possible production defects, and verify compliance with the specifications required by the market.
Testing procedures according to tube diameter
Testing procedures vary depending on the diameter of the tube. Small-diameter tubes can generally be tested directly on the complete tube section. For larger diameters, a longitudinal strip is usually extracted from the tube wall in order to obtain a standardized flat specimen. This method ensures correct specimen clamping and prevents unwanted deformation that could affect test accuracy.
International standards for metal tube testing
Tensile testing of metallic materials must comply with internationally recognized standards to ensure reliable, repeatable and comparable test results.
The standards most commonly applied in the industry include:
- ISO 6892-1 for tensile testing of metallic materials at room temperature;
- ASTM E8 for mechanical testing of metals;
- ISO 8496 for ring tensile testing of metallic tubes.
Compliance with these standards is particularly important in highly regulated industries, where certification of mechanical properties is an essential requirement.
Customized testing technologies: the Easydur approach
Easydur’s extensive range of testing systems allows manufacturers to perform different types of mechanical tests while adapting to both standard production environments and highly specialized applications. Whenever standard configurations are not sufficient, Easydur develops customized testing solutions engineered around the customer’s specific production requirements.
