New Delivery for N08825 Hydraulic Control Line Tubing - Inconel 625 Hydraulic Control Line Tube – MEILONG Detail:
Product Introduction
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.
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.
