... piping and downhole production tubulars had been previously experienced. TUBING MATERIAL SELECTION The original proposal called for the tubing to be manufactured from either 22 or 25 chrome or possibly one of the super duplex alloys. Because of the cost, a materials review was performed to assess all...

...Abstract Corrosion resistance of some downhole tubing materials were studied in a recirculating flow loop simulating conditions that induce flow enhanced corrosion. The selected materials included carbon steels (AISI 1018, API X-52), coiled tubing, 0.5% Cr, and 13% Cr (AISI 420) martensitic steel...
