FEP Encapsulated Incoloy 825 Control Line Flatpack

Short Description:

Meilong Tube’s downhole control lines are used primarily as communication conduits for hydraulically operated downhole devices in oil, gas, and water-injection wells, where durability and resistance to extreme harsh conditions are required.

Welded Control Lines are the preferred construction for control lines being used in downhole oil and gas applications. Our welded control lines are used in SCSSV, Chemical Injection, Advanced Well Completions, and Gauge Applications. We offer a variety of control lines.

Alloy Feature

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.

Tubing Process and Packing

Seamless: pierced, redrawn, annealed (multi-pass circulation process)

Welded: longitudinally welded, redrawn, annealed (multi-pass circulation process)

Packing: Flatpack is level wound coiled on the metal / wooden drums or spools.

All drums or spools are packed in wooden crates for easy logistic operation.
