ASTM B704 Incoloy 825 High Tensile Chemical Injection Line Nickel Alloy Tubing

 

Welded and redrawn injection lines are the preferred construction for injection 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 or Laser 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.

 

Typical Size of Injection Line

 

Outside diameter of control lines is mainly 3/8’’ (9.53mm).

Wall thicknesses: 0.035’’ (0.89mm), 0.049’’ (1.24mm), 0.065’’ (1.65mm)

Control line tubing is available in lengths from 400 feet (122 meters) to 32,808 feet (10,000 meters). No orbitally butt welds.

Other specifications (1/8’’ to 3/4’’) are available on request.

 

Precision Manufacturing

 

Meilong Tube operates from a complex of buildings totaling 20,000 square meters.

Each one tubing coil is a completely continuous length without orbital welds.

Each one tubing coil is hydrostatic tested with a targeted pressure.

The test can be witnessed on site by the third party inspectors (SGS, BV, DNV).

Heat Treatment

 

The tubing is heat-treated to achieve specified mechanical properties and corrosion resistance in an off-mill furnace with a reducing atmosphere.

 

Application Description for SSSV

 

A safety valve is a valve that acts as the protector of your equipment. Safety valves can prevent damage to your pressure vessels and even prevent explosions at your facility when installed in pressure vessels.

 

A safety valve is a type of valve that automatically actuates when the pressure of the inlet side of the valve increases to a predetermined pressure, to open the valve disc and discharge the fluid. The safety valve system is designed to be a fail-safe so that a wellbore can be isolated in the event of any system failure or damage to the surface production-control facilities.

 

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.
