Features: Inconel 625 has excellent strength at temperatures up to 816℃. At higher temperatures, its strength is generally lower than that of other solid solution strengthened alloys. Inconel 625 has good oxidation resistance at temperatures up to 980℃ and shows good resistance to aqueous corrosion, but is relatively moderate compared to other more capable corrosion resistant alloys.

Applications: Chemical process industry and sea water application. Inconel 625 is used in short term applications at temperatures up to 816℃. For long term service, it is best restricted to a maximum of 593℃, because long term exposure above 593℃ will result in significant embrittlement.

process

An increasing number of projects in the oil service industry require the use of continuous lengths of nickel alloy capillary tube. They are used in a variety of applications, including chemical injection, hydraulic control, instrumentation umbilicals and flowline control. MTSCO offers products for all of these applications, helping customers reduce operating costs and improve recovery methods.

MTSCO can provide continuous tubing for nickel alloy, stainless steel and duplex capillary tube. Sizes, lengths, pressure levels, packaging methods, etc. can all be customized to improve your oil recovery methods and reduce operating costs.
