Sandvik Materials Technology manufactures Piping for Flowlines and Production Risers. Sandvik Materials Technology manufactures high technology stainless steels, special alloy materials and advanced value-added products, developed in close cooperation with customers. The Piping for Flowlines and Production Risers are designed to resist corrosion without the use of costly inhibitors. The company supplies a complete range of piping for flow lines and production risers - in duplex and super-duplex stainless steels, as well as in Ni-based alloys. The substantial reduction in the cost of treatment facilities will, in many cases, easily compensate for the higher initial cost of the stainless flow line. By using stainless steel the total weight of the piping system can be reduced. As the corrosion rate is negligible, there is no need for a corrosion allowance.
