Submerged Arc Welded Pipes (SAW)
As a special business partner of well-known and leading manufacturers worldwide - from Canada and Europe to South Korea, ZAFFERTEC S.L. is well-placed to work with any client in applications or projects in which submerged arc welded (SAW) pipes are the core required material.
SAW pipes are produced using both longitudinal and spiral welding methods. Many steel grades up to API X80 are used, as well as grades with similar specifications such as low alloy steels for sour service corrosive environments. Our mills are capable of producing very thick walls with very close tolerances and in large sizes of up to 84 inches implying that strong and reliable pipes for special applications are supplied as well.
Heat treatments for all sizes of pipes can be applied on site at our mills. Ultrasonic, X-Ray and all required non-destructive tests (NDT) can also be carried out by the manufacturer according to client requirements.
Standards: API 5L grade B, X42, X46, X52, X56, X60, X65, X70, X80, ASTM A515, A516, A387, A672 B65, A671 grade CC60/65, A682 C70, BS7191, EN 10225.
