Tubes for Oil & Gas tools

Tenaris produces a wide range of hot rolled and cold drawn seamless tubes in different steel grades (4130 & 4140) used in a wide variety of applications for the oil & gas industry as components of complex well drilling and maintenance devices such as perforating guns, sand screens and power sections for down-hole drill motors. The steels used for these applications guarantee high resistance to yield strength and tight dimensional tolerances.

Standards Compliant with ASTM A519 & some requirements of API 5CT (equivalent to ISO 11960:2004)

One of the most critical applications in this sector are carrier tubing used at the heart of perforating guns, the devices that perforate oil and gas wells in preparation for production using explosive charges. These products are a joint development between end users and Tenaris, which specifically designs a product based upon customer’s needs, including tailor-made chemistry and process design.

For this demanding application, Tenaris provides low alloyed, quenched and tempered steel tubes guaranteeing high performances in terms of high yield strength combined with high toughness and tight internal diameter tolerances. They provide also high impact resistance during explosive charges detonation maintaining their structural integrity and the one of the entire perforating system.
