Meilong Tube's downhole control lines are mainly used as a pathway for communication in the operation of downhole devices in oil, gas, and water-injection wells. It is essential for these lines to be highly durable and have the capacity to withstand the extreme harsh conditions, making it customizable for various applications and downhole components.
The material is hydrolytically stable and is compatible with all kinds of well completion fluids, including high-pressure gas. The selection for optimal material is based on bottomhole temperature, hardness, tensile and tear strength, water absorption and gas permeability, oxidation, and abrasion and chemical resistance. Furthermore, many tests have been conducted to guarantee its reliable performance, such as through the crush testing and high-pressure autoclave well simulation.
TP316L, an austenitic chromium-nickel stainless steel with molybdenum, is well-known for its excellent corrosion-resistance with organic acids under high concentrations and temperatures, inorganic acids like phosphoric and sulphuric acids (up to concentrations above precent 90 below low temperatures), salt solutions, sulphates, sulphides and sulphites, as well as caustic environments. Its low carbon content also gives it better protection against intergranular corrosion than other types, such as TP316. However, it would be wise to avoid potential stress corrosion cracking from occurring at temperatures above 140°F when exposed to high tension in contact with certain solutions, particularly containing chlorides.
Our Control lines are designed for reliability and are available in lengths of up to 40,000 feet (12,192 m) without the need of orbital welding. We offer a range of options, including single, double, or triple flat-packs. These can be bundled with downhole electrical cables and/or bumper wires to make installation and handling easier.
Our production process allows us to provide perfect, round tubes with a seamless construction or weld-and-plug-drawn design, which provides a long-term seal to the termination. We make sure that the encapsulation materials used are carefully chosen with the well conditions in mind to ensure longevity and reliability.
Control lines are an indispensable part of modern industrial production. They are used to change or transmit signals, power, data or other information to other components or systems. Chemical injection lines are fluid passages connecting two points. They are usually used to supply treatments such as main acid stimulation, corrosion inhibitor, and other products to the required point of a system. Electrical lines provide power to electrical equipment, motors, and actuators in order to control machinery.
Multi-line flat packs are used for handling up to four lines, generally for C-ring or flange operation on separator, and manifold systems. Hydraulic lines are used to transmit mechanical power from one point to another. Tubing encapsulated conductors are used in applications such as christmas tree valves and remote monitoring systems. Intelligent well completions are wellbore systems designed to streamline the productivity of a well. Finally, capillary tubing is used to transmit signals, chemicals, and other fluids over long distances.
