Any client’s request, from a single item to a complete project, is supplied thanks to a planning system that can be adjusted to any last-minute urgency.

By using as raw material tubes having the same diameter and thickness than the fitting to produce, Tecninox can draw from Raccortubi stock according to each specific order destined for production.

In addition, the system can precisely anticipate the quantity of material needed to replenish Raccortubi stocks, for both client orders and last-minute urgencies, relying on sophisticated Finite Capacity Scheduling.

A constant production flow derives from such a planning, in order to maximizing the use of materials and the control over each manufacturing phase, while benefitting from the advantage of inserting new orders without affecting the already scheduled delivery deadlines.

Quality checks are implemented throughout the entire manufacturing process at Tecninox.

A thorough selection of raw materials as well as the relevant investments in technology that led to the realizationof an automated area for dimensional tests, PMI, marking and packing operations, allow Raccortubi to supply high-quality finished products.


PMI, Hardness and Liquid Penetrant Testing, feritscope are carried out in-house, while other destructive or not destructive tests are performed by external laboratories, conveniently certified by international bodies and liaising with Raccortubi Group for a long time.

Chemical compositions, mechanical values and additional tests of duplex, super duplex and 6Mo are carefully controlled to maintain the highest standards.
