We manufacture and supply an important range of seamless cold drawn tubes heat treated in our installation for Quench and Tempering.
Our specialities permit us to deliver to the geotechnical market.

We keep in stock a regular range in those dimensions :

Ø OD (mm) Ø ID (mm) Thickness (mm) Linear Weight (Kg/m)
22 12 5 2,097
25 15 5 2,467
32 18 7 4,317
36,5 16,35 10 6,536
44 26 9 7,770
44,5 20 12 9,620
55 39,25 7,5 8,787

All those tubes can be heat treated to achieve special mechanical characteristics according the customer’s needs.
Our heat treatment process permit high mechanical strengths added with high resilience.

For example, you can see below the delivery mechanical properties :
Re ≥ 1050-1150 N/mm² – Rm ≥ 1150-1250 N/mm² – A ≥ 10 % – Z ≥ 45 % – KV at 20°C ≥ 35 J

All tubes can be sawed according customer’s requirements.
