BUTTING ǀ Metallurgically clad pipes Metallurgically clad pipes Already since the mid eighties we have been producing pipes from metallurgically clad plates for renowned customers all over the world. The tight bond between the metal layers of these pipes is achieved by a diffusion bridge. Depending on their intended application and technical requirements metallurgically clad pipes are used, for example, as SCR pipes, riser pipes, process or line pipes. Technical details at a glance: • Sizes range from OD 114.3 (4") up to OD 1 219 mm (48") • Wall thicknesses up to 70 mm • Maximum wall thickness / OD ratio 1:10 • Random lengths up to 12 m (up to 24 m with circumferential weld) • Produced in accordance with API and DNV • Suitable for S-Lay and J-Lay method, bundle or Reel-Lay process Benefits of metallurgically clad pipes: • A wide range of materials and combination options • High corrosion resistance at the inside and high pressure resistance at the outside • Cost savings compared to solid pipes •

jection lines or pipelines for the transport of waste water. The many fields of application of metallurgically clad pipes require a wide range of dimensions. For pipes made from plate sizes ranging from 4"–48" and wall thickness/diameter ratios of 1 to 9 can be taken into account. The production of metallurgically clad pipes is based on the requirements of API or DNV GL and it starts with the manufacture of metallurgically clad plates, as described in chapter 2.1. During goods income control the plates are being tested according to specific requirements including identification of possible damages...
