High Quality for Alloy 625 Hydraulic Control Line Tubing - Hydraulic Control Line – MEILONG
High Quality for Alloy 625 Hydraulic Control Line Tubing - Hydraulic Control Line – MEILONG Detail:
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.
Control lines have undergone extensive development, including crush testing and high-pressure autoclave well simulation. Laboratory crush tests have demonstrated the increased loading under which encapsulated tubing can maintain functional integrity, particularly where wire-strand “bumper wires” are used.
Application
For SSSV (sub-surface safety valve)
In most cases, it is mandatory to have a means of closure for all wells capable of natural flow to the surface. The installation of a subsurface safety valve (SSSV) will provide this emergency closure capability. Safety systems may be operated on a fail-safe principle from a control panel located on the surface.
The SCSSV is controlled by a ¼” stainless steel control line that is attached to the outside of the well tubing string and installed when the production tubing is installed. Depending on the wellhead pressure, it may be necessary to keep as much as 10,000 psi on the control line to keep the valve open.
Other applications:
Capillary coiled alloy tubing for chemical injection.
Bare and encapsulated hydraulic control line coiled alloy tubing for subsea safety valves.
Velocity strings, work strings, and steel tube umbilicals.
Geothermal coiled alloy tubing.
