Weld beads
Internal and external weld beads are fully trimmed and removed, providing a clear, unrestricted tube bore.

We conduct both Non-Destructive (NDT) and Destructive Testing (DT) to provide assured confidence in weld seam integrity. All weld seams are ultrasonically tested (V=1.0) as standard.

Based on EN ISO3183 and L-Grades and other equivalent and generally equivalent European and international standards for industrial market applications.

Based on EN10217-2 and P-Grades and other relevant standards, ideal for general purpose and industrial pressure requirements.
