  Frequently Asked Questions

 

 

 

Why cladding in pipes and fittings?

Cladding inside the pipes and fittings is to economize the cost of pipelines for corrosion applications for pressurized Oil & Gas and Refinery piping. The design pressure is taken care by carbon steel or low alloy steel and corrosion is tackled by the cladded material inside the pipe.



What are the commonly cladded materials?

Inconel 625, Inconel 825, Hastelloy, Monel, Duplex, SS410, SS316 are commonly cladded material.



What is the typical thickness of undiluted chemistry required inside the pipe?

For a typical application undiluted chemistry skin thickness considered is 3mm



Why weld overlayed cladding?

Weld overlayed cladding is typically used for high pressure and high temperature applications as it provides a concrete solution for a differential thermal expansion between back up and clad material



What are the applications of cladded pipes and fittings?

Cladded Pipes and fittings are commonly used for corrosion application in Hydro-carbon industry as these are typically sour and corrosive.



What are the quality checks in the weld cladding process?

Typical quality checks in the cladding process would be as listed below:

  • Base metal, clad metal chemistry
  • Clad metal skin Chemistry
  • PMI
  • Ultrasonic Testing
  • D.P / P.T examination of clad surface
  • G-28 intragranular corrosion test


What is the maximum length of the single piece of Cladded pipe?

Minimum Dia of clad pipe available is 1.5" but length is limited to 500mm but for 5" and above to cladded pipe can be manufactured up to 12 meter long in one piece.



Are cladded spools available?
