n: a tubing sub made of abrasionresistant material. It is used in a tubing string where high-velocity flow through perforations may cause external erosion.

an abrasion and erosion resistant tube that is run where ever direct sand impingement is a problem.

a selected constant in the API 14-E equation on fluid erosion.

a erosion resistant covering or main pipe that is used when tubing is set deeper than the perforations or on the long string across from the upper perforations in a side-by-side completion.

expanding pipe installed in production casing or tubing to seal perforation holes or leaks caused by corrosion or erosion. Can be metal or plastic.

a surface separating younger from older rocks with no indication of erosion or other disturbance.

n: The method that sustaining piece of core to prevent core stuck and decrease erosion with local reversal circulation in order to improve core recovery when core drilling in hard and brittle formation.

eroding away of a protective film of corrosion product by the action of a process stream, exposing fresh metal which then corrodes.

a test strip of metal used in corrosion and erosion testing.

the maximum flow rate that avoids damage to the pipe from corrosion or erosion.

setting a maximum flow rate to minimize erosion corrosion.
