ASTM B704 Nickel Alloy Super Long Welded Coiled Tubing For Oil
Field
Grade: Alloy 625/UNS N06625, Alloy 825/UNS N08825 etc.
OD: 2.38-25.4mm
WT: 0.51-2.65mm
Length: ＜10000 m/coil
Features: Alloy 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. Alloy 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. Alloy 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.
