Fabrication and Inspection of Alloy Steel Piping

IN the last ten years great strides have been made in the development of inertgas shielded arc welding for the fabrication of steel alloy piping as used in steam power plants, refineries, the chemical industry and military and atomic energy installations. The world's expanding indus-tries require ever more and better equipment in order to fill the demands of the people.There is hardly any indus-trial plant which does not use some welded alloy piping, may it be for corrosive chemicals, high-pressure steam, radioactive waste materials, etc.
