Corrosion Resistant Alloy Inspection Clad Pipe ILI

Clad pipes consist of an internal CRA layer which is metallurgically bonded to the backing carbon-steel. Different manufacturing processes (e.g. hot rolling or weld overlay) are used to bond the CRA layer to the carbon steel. In contrast to clad pipes, lined pipes have a CRA lining that is mechanically bonded to the carrier pipe . Demand increasing for exotic alloys in piping OffshoreDemand for special pipe will likely remain high over the next five years, with the oil and gas industry in investment mode. Due to concerns over clad pipe capacity limitations, and associated capacity for substrate material, demand will also likely grow for weld overlay CRA pipe , he suggested. Design and Welding Challenges in the Infield Flowlines of CRA Clad Pipe Welding Systems for Offshore PipelinesThe pipelines are designed and fabricated in accordance with DNV OS-F101 supplemented by new guidance emerging from a DNV joint industry project on clad and lined materials.

Field Welding of CRA Pipelines Transporting Sour Gas

One solution to transporting so called sour gas is to use standard steel piping internally lined with a corrosion resistant alloy (CRA ). This is usually Inconel 625 alloy (NiCrMo-3). The pipe can be lined with a tube of this material which is inserted into the id and mechanically expanded. Alternately, the id can be clad with a weld overlay. Flow assurance work process Depending on pipe manufacturing process, there are several pipe types as Seamless pipe DSAW (double submerged arc welding ) pipe or UOE pipe ERW (electric resistant welding ) pipe Seamless pipe is made by piercing the hot steel rod, without longitudinal welds. It is most expensive but ideal for small diameter, deepwater, or Fusion Cladding Prevents Pipeline Wear and CorrosionAs a representative system , alloy 625 was applied to samples and pipe IDs (10-in. X65 line pipe ), and compared to wrought and weld overlay materials. The fusion-clad materials exhibited properties between those of wrought and weld overlay materials, with corrosion and microstruc-tural properties closer to wrought than weld material. Fig-

Growing need for exotic alloys in oil and gas CRA Clad Pipe Welding Systems for Offshore Pipelines - Offshore

Offshore staff. LONDON Current demand for corrosion resistant alloys (CRAs) for oil and gas production is unprecedented, according to consultant Westwood.. Kashagan in the Caspian Sea, one of the largest sour gas field developments to date, required 60,000 metric tons of clad pipe material, said Matt Loffman, associate director, Rigs & Wells, in part due to IN-LINE INSPECTION OF PIPES USING CORROSION This system is primarily used in bends, installations and at the ends of pipe spools, but it would be applicable for nearly all wear and corrosion endangered installation or applications. Due to the welding process a rougher inner pipeline surface can occur. CRA pipelines are described e.g. by PALMER and KING [3].
