PriceList for Alloy 625 Capillary Tube Control Line - Incoloy 825 Control Line Flatpack – MEILONG

Product Introduction

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. These lines can be custom configured for a variety of applications and downhole components. 

All encapsulated materials are hydrolytically stable and are compatible with all typical well completion fluids, including high-pressure gas. The material selection is based on various criteria, including bottomhole temperature, hardness, tensile and tear strength, water absorption and gas permeability, oxidation, and abrasion and chemical resistance.

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.
