1 / 8 ASTM B704 Incoloy 625 Seamless Hydraulic Control Line Tubing for Oil & Gas
Tiptop is a supplier of welded and redrawn, seamless and redrawn capillary tube made from corrosion-resistant incoloy 625. We have been specializing in providing capillary tubes with different sizes for the oil and gas industry.
Type 625 Alloy (UNS Designation NO6625) is an austenitic nickel-based super alloy possessing excellent resistance to oxidation and corrosion over a broad range of corrosive conditions, including jet engine environments and in many other aerospace and chemical process applications. The alloy has outstanding strength and toughness at temperatures ranging from cryogenic temperature to 2000°F (1093°C). Type 625 alloy also has exceptional fatigue resistance. It derives its strength from the solid solution strengthening effects of molybdenum and columbium on the nickel-chromium matrix. Although the alloy was developed for high temperature strength, its highly alloyed composition provides a high level of general corrosion resistance to a wide range of oxidizing and non-oxidizing environments.
Incoloy 625 capillary tube has excellent resistance to sulfuric acid and phosphoric acid corrosion, intergranular corrosion after welding. It won’t lead chloride stress corrosion cracking. With excellent resistance to pitting corrosion and crevice corrosion in a chloride ion-containing medium environment, it boasts great resistance to stress corrosion under sodium chloride salt solution medium. In addition, it has high strength and good toughness. It's mainly applied in petroleum industry, chemical industry, shipbuilding, natural gas, and etc.
