Internal Pipe clad
Metallurgically Bonded (CLAD) or Mechanically Bonded (LINED) Pipes are seamless and welded clad steel line pipe and lined steel line pipe with enhanced corrosion-resistant properties pipes which are extensively used in pipeline transportation systems in the natural gas & petroleum industries, marine applications, chemical plant, power plant, etc.
The corrosion-resistant alloy clad or lined pipe is made up of conventional carbon steel and a corrosion-resistant alloy layer. The internal or external surface of the steel pipes are bonded metallurgically (clad) or mechanically (lined) with corrosion-resistant alloy (CRA) layer. The CRA layer is the cladding material or lining whereas the base metal is carbon steel or low alloy pipe steel is the base metal. The thin CRA layer not only holds the corrosion-resistant properties but also reduces the cost thus making it economically viable for large diameter heavy pipelines.
