The most common reasons For Inconel 625 Hydraulic Control Line
A downhole safety valve that is operated from surface facilities through a control line strapped to the external surface of the production tubing. Two basic types of SCSSV are common: wireline retrievable, whereby the principal safety-valve components can be run and retrieved on slickline, and tubing retrievable, in which the entire safety-valve assembly is installed with the tubing string. The control system operates in a fail-safe mode, with hydraulic control pressure used to hold open a ball or flapper assembly that will close if the control pressure is lost.
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. (TIG Welded, and floating plug drawn, and lines with enhancements) The various processes provide us the ability to customize a solution to meet your well completion.
Inconel 625 is a material with excellent pitting, crevice and corrosion cracking resistance. Highly resistant in a wide range of organic and mineral acids. Good high temperature strength.
Characteristics
Excellent mechanical properties at both extremely low and extremely high temperatures. Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion.Almost complete freedom from chloride induced stress corrosion cracking. High resistance to oxidation at elevated temperatures up to 1050C. Good resistance to acids, such as nitric, phosphoric, sulfuric and hydrochloric, as well as to alkalis makes possible the construction of thin structural parts of high heat transfer.
Application
Components where exposure to sea water and high mechanical stresses are required.Oil and gas production where hydrogen sulfide and elementary sulfur exist at temperatures in excess of 150C.Components exposed to flue gas or in flue gas desulfurization plants.Flare stacks on offshore oil platforms. Hydrocarbon processing from tar-sand and oil-shale recovery projects.
