Oil and Gas

Tuper produces carbon steel welded pipes by the HFIW – High Frequency Induction Welding process used in the oil and gas industry, in various conduction applications, through the use of API 5L pipes, and also in production and exploration (OCTG) with API 5CT pipes.  These pipes can be coated, which ensures the pipes anticorrosion and mechanical protection, according to the application’s needs. Besides API pipes, there are also solutions in structural and industrial tubes, black and galvanized, in various standards and norms for diverse applications in this segment.
