Tubi di rivestimento IDT CASINGS are manufactured according to standard API 5CT, in use in the petroleum field.
To ensure superior characteristics to this product, each casing has been obtained by welding to the pipe extremity the two threaded connections, previously treated thermo-chemically, in order to give the threads a superficial hardness.
The result is a smoother unscrew of the casing and consequently a significant increase in wear resistance.
As for the rods , even in the production of the casings we use friction welding quality steel that is highly selected. The result is a product with high mechanical properties, durability and reliability.
