TRAFILTUBI is certified:
* ISO 9001:2000
* PED (pressure equipment directive - 97/23/CE e DLGS 93)
* WESTLAND HELICOPTERS Ltd (WHL)
The Certification laboratory
The internal Quality Control constantly checks the processes and products according to certified procedures.
The Trafiltubi Laboratory is well equipped to make:
* mechanical tests: tensile, hardness, flaring, flattening tests.
* non destructive tests: Eddy Current, penetrant liquid, ultrasonic, hydrostatic tests.
* micrography: decarburization, dimensional control, grain size, intergranular corrosive tests.
* chemical analysis: chemical analisys by spectrometer, high precision Carbon text.
* dimensional check: roughness test.
With every order, the Laboratory carries out a test certification in line with UNI EN 10204 - 3.1
On the Client's request, special controls and trials are carried out and certified including with external bodies: TUV, DNV, L.R. etc.
Raw Material Warehouse
In order to provide a better service and the shortest delivery time possible, Trafiltubi has a vast warehouse of raw material both with stainless steel and low alloy and carbon fibre steel: 700 tons.
Tooling department and shape production
As well as having a vast warehouse of ready tools, Trafiltubi feels that their complete autonomy in being able to quickly produce the widest range of special equipment, is strategic. Subsequently, the internal tool department uses CNC machinery to build matrices and mandrils to design.
Special shaped profiles with particular specifications are created according to the most varied of clients' needs. It is possible for clients to have equipment specifically set aside for them.
Chemical treatment departments
In the sequential tub plant, the chemical processes needed to oil the piping is carried out both for carbon fibre and stainless steels. The finishing touch processes to the pipes is also carried out in this plant: dephosphatisation, pickling and passivation.
Drawing
The department has four drawing plants (three multiple tension) with different capacities: 10 tons, 20 tons and 50 tons and one 15 ton one with the possibility of producing different thicknesses on the same pipe.
Thermal treatment departments
The thermal treatment is carefully balanced and repeated at different stages throughout the work and is a guarantee for the creation of the end products capable of meeting the highest technical needs.
Trafiltubi's aim is to carry out not only the "classic" thermal treatments (solubization, annealing, standardisation, air-hardening, reconstitution and stress relieving), but also special treatments to meet Clients' specific needs. The department has two different ovens that can carry out treatments up to 1.100°C. Both ovens have an electronic temperature and speed control that allow for the monitoring and recording of critical parameters for the successful result of the treatment itself. All the treatments are carried out under controlled conditions.
Finishing touches department
As well as the classic straightening and cutting operations, the finishing touches department can carry out other work: cutting to length (cut into small pieces), glazing, pipe marking, oiling, demagnetisation, special packaging.
Non-destructive control department
Trafiltubi has an automatic plant for non-destructive Eddy Current control, aimed at looking for both radial defects and longitudinal ones. This line, in fact, is fitted with a rotating head control for superficial, longitudinal defects, and a winding spool apparatus to search for radial defects.
Fast Shipment Warehouse
Our fast shipment pipe warehouse offers an exclusive service to clients who need fast delivery of top quality materials. There are always pipes available in the warehouse of the most popular size and quality for the aeronautical sector, frame fitting and karting. As well as the examples given in the table below, others are periodically added that are linked to the work in progress, such as particular edged profiles or those obtained with other special kinds of work.
