SRM (Strech and Reduced) Pipes

Applications:
Compared to standard piping, SRM pipes are preferred due to their properties such as malleability and high resistance to corrosion, as well as machinability.

  • Natural gas pipe line
  • Oil pipe lines
  • Onshore structures
  • Construction Base
  • Steel Struction Base
  • General industrial applications
