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.

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-
