The EH9 has been tested in high CO2 enviornments that traditionally plague the common carbon-based 4330 steel rods. EH9 has already improved some of our opeartors' run life 3-times longer than that of what they had experienced over the past 3-years of data collecting.
The EH9 has also been developed into a corrosion resistant coupling while retaining the hardenss closer to that of a T-Coupling. Customers had constant issues with Spray Metal couplings wearing away their L-80 tubing, while the T-Couplings could not handle the corrosive environment downhole. Here entered the EH9 Coupling. Made from the same core raw material as the EH9 rod, this coupling is reducing failures due to tubing wear and corrosion effects of H2S and CO2.
