High Strength Applications

Tenaris produces a large dimensional range of seamless tubes in high strength steel for engineering and structural applications

 

INCREASED LOAD CAPACITY WITH HIGH STRENGTH STEEL TUBES

Tenaris produces a large dimensional range of seamless tubes in high strength steel for engineering and structural applications where the critical factor is controlling weight and a high resistance to stress requirement. Our structural tubes are used, for example, in lifting and load handling systems and as components of lift arms in mobile cranes.

For these applications, high-performance steels (fine-grain, high-strength steels) with excellent strength resistance and resilience values are used, it means that the stress resistance of the systems can be increased, thus also guaranteeing their use in extreme environmental conditions.

Furthermore, the chemical composition of our seamless steel tubes is carefully controlled in order to guarantee good weld-ability, a fundamental issue for structures made of tubular components welded together.

Tenaris high strength tubes are the most suitable solution in steel constructions for civil and engineering purposes, where the relationship between mass and space occupied is very critical.

STEEL GRADES AND DIMENSIONAL RANGE

For this application, our seamless carbon-manganese-molybdenum (e.g., S460, S590, S690, S770 and S890) steel tubes are supplied in hot-rolled and quenched and tempered conditions, in a wide range of sizes:

  • S460 and S590: outer diameter from 48.3 mm to 508 mm and wall thickness from 4 mm to 50 mm
  • S690 and S770: outer diameter from 48.3 mm to 508 mm and wall thickness from 4 mm to 50mm
  • S890: outer diameter from 48.3 mm to 508 mm and wall thickness from 10 mm to 50 mm
