Downhole Equipment

Historically, high alloy downhole completion equipment has been manufactured from precipitation hardened “PH” bar stock. Often times starting with bar results in a significant amount of material loss, additional machining time and costs, and limitations to part lengths when compared to starting with a cold-worked tube.

Utilizing our job shop mill, CRA produces a wide range of cold worked seamless heavy-walled tubes for mechanical applications in the oil & gas industry. CRA manufactured tubes are offered to semi-finished near shape dimensions with close tolerances allowing for significant reduction in machining hours and cost. Providing quality and reliable products produced with accelerated deliveries provides opportunities to meet customer’s delivery requirements while reducing inventory risk.
