Duplex 2205 Downhole Chemical Injection Tubing
ASTM A789 Duplex 2205 Downhole Hydraulic and Chemical Injection Tubing
Duplex 2205 seam-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.
Tiptop offers a variety of duplex stainless steel, super duplex stainless steel welded and seamless tubing, depending upon the properties the tubing is required to exhibit. Other alloys and sizes are also available upon request. Duplex stainless steels (named for their austenite and ferrite compositions), has greater yield strength than austenitic stainless steel.
