QUALITY CONTROL
All TLA processes are procedural and quality-controlled, from raw materials and tubes to intermediate processes and all auxiliary services, from coil or tube cutting to logistics.
PRODUCTION LINE TESTING:
Production line testing:
Eddy current for 100% of production.
Dimensional tests.
Destructive tests (crushing, widening, flaring).
Continuous analysis of the geometry in the welding area.
LABORATORY TEST:
Dimensional tests.
Tensile tests.
Surface hardness (if required).
Roughness (if required).

SKILLED WORKFORCE
The high degree of versatility of the production staff and the parameterisation of the production processes at TLA allows us to commit ourselves to the most demanding specifications and technical requirements on a permanent basis.
The tube manufacturing process in both production lines has continuous in-line controls such as temperature controls with pyrometer and 3D Xiris® inspection system for welding by laser vision that allows us to detect and correct defects in the welding area at the very instant they are detected. Also with 100% eddy current product control
In each production line, but off line, the tube is subjected to dimensional and destructive controls – crushing, flaring and expansion both at room temperature and in more demanding conditions in the case of ferritic tube (at -20°C) – which ensure the correct quality of the weld.
In addition to these controls, laboratory tests are carried out where mechanical tensile tests are performed on the tube, as well as hardness and metallographic tests.
