Welded tubes for pressure purposes EN 10217-3

  • alloyed fine grain steels

Welded boiler tubes of this standard have extraordinary temperature and pressure resistance. The once again higher resistance is an essential feature, as a special characteristic of these tubes. While not all qualities are apparent due to the production process, these tubes are far more efficient compared to seamless boiler tubes.

Upon request, an additional inspection can be carried out for a fee by an expert appointed by the customer.
