REQUIREMENTS FOR THE MANUFACTURING OF REPLACEMENT RIGHTS FROM SWITZERLAND FOR FLEXIBLE RAILWAY VEHICLES FOR THE TRANSPORT OF COAL WATER MATERIALS, AND STRENGTHEN LEADING

摘要

A process for manufacturing plated-steel armor wires intended for reinforcement of flexible tubular pipes for transporting hydrocarbons, comprising a plating coating is intimately bonded, by high pressure, to a core made of hardenable steel with moderate mechanical properties, and then the plated wire obtained undergoes a rapid high-temperature hardening step followed by a tempering step.
