Cold Drawing Nickel Alloy Tubing Chemical Injection Line 100% Length Hydrostatic

As the oil and gas industry moves into deeper and harsher waters, where extreme offshore environments demand extreme safety, Meilong Tube strives to help you select the “right” corrosion resistant material for coiled umbilical tubing to improve safety and reliability. We are dedicated to driving innovation and advancement in this field.  

Features:

Incoloy alloy 825 is a nickel-iron-chromium alloy with additions of molybdenum and copper. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion.

It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Alloy 825 is especially resistant to sulfuric and phosphoric acids. This nickel steel alloy is used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.

• Excellent resistance to reducing and oxidizing acids
• Good resistance to stress-corrosion cracking
• Satisfactory resistance to localized attack like pitting and crevice corrosion
• Very resistant to sulfuric and phosphoric acids
• Good mechanical properties at both room and elevated temperatures up to approximately 1020° F
• Permission for pressure-vessel use at wall temperatures up to 800°F
