Duplex 2205 welded pressure tubing

2205 is a duplex (austenitic-ferritic) stainless steel containing about 40 - 50% ferrite in the annealed condition. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304/304L or 316/316L stainless.




High resistance to chloride stress corrosion cracking

Chloride pitting and crevice corrosion resistance superior to 317L stainless

Good general corrosion resistance

High strength

Good sulfide stress corrosion resistance

Useful up to 600°F


Chemical process vessels, piping, and heat exchangers

Oil field piping, heat exchangers


Instructions for 1/8” Hydraulic control line


1/8” Hydraulic control line, also called capillary tube, mainly used for oil and gas field underground capillary pressure measurement. The temperature and pressure sensor (also known as a downhole permanent pressure gauge, generally a nitrogen cylinder) and the production string of the oil and gas well are run into the oil and gas layer several kilometers deep, and then the 1/8 “hydraulic control line (capillary) The temperature and pressure sensors are always connected to the surface of the fluorescent display, so that the downhole temperature and pressure can be transmitted to the surface through the capillary tube, and the instantaneous temperature and pressure at the downhole oil and gas layer can be read out through the fluorescent screen of the surface display, thereby realizing the downhole temperature and pressure,so as to realize the real-time monitoring of downhole temperature and pressure. It can also be used for pressure control of surface safety valves and other surface valves, and various connection tubelines of large-scale equipment instrumentation control systems for oil and gas field drilling and oil production.
