SS Hydraulic Tubing w/ Enhanced Mechanical Properties 100% Length Eddy Current Tested Annealed
Product Description:
One of the main challenges in the upstream processes of the oil and gas industry is to protect pipeline and process equipment against waxes, scaling and asphalthane deposits. The engineering disciplines involved in flow assurance play an essential part in mapping the requirements that reduce or prevent loss of production due to pipeline or process equipment blockage. Coiled tubing from Meilong Tube is applied to umbilicals and chemical injection systems play an effective role in chemical storage and delivery at an optimizing flow assurance.
Our tubing is characterized with integrity and quality to be specially used in subsea conditions in the industries of oil and gas extraction.
Meilong Tube manufactures corrosion resistant alloy hydraulic control line tubing products for a variety of upstream oil and gas and geothermal applications. Meilong Tube has extensive experience in producing coiled tubing from duplex, nickel alloy and stainless steel grades to industry and customer-specific requirements.
Meilong Tube also offers Surface-Controlled Subsurface Safety Valves (SCSSV). This is a downhole safety valve that is operated from surface facilities through a control line strapped to the external surface of the production tubing. There are two basic types: one is wireline retrievable, whereby the principal safety-valve components can be run and retrieved on slickline, and the other one is 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.
Features:
Precision Manufacturing
Meilong Tube operates from a complex of buildings totaling 20,000 square meters.
Tube mill
Tubing is formed and gas-tungsten arc and laser beam welded from strip stock on multiple tube mills designed and fabricated by Meilong Tube.
Sinking operation
Sinking is a cold working process in which tubing is pulled through a lubricated die without an internal plug. For certain tubing dimensions, manufacturing process limitations prevent welding the tubing to final size. In such cases, the tubing is welded at a larger outside diameter and sunk in multiple reduction / heat treatment operations.
Floating-plug operation
Floating-plug operation is a cold working process in which tubing is pulled through a lubricate die with an internal floating plug which controls inside diameter of tubing.
Heat treatment
The tubing is heat-treated to achieve specified mechanical properties and corrosion resistance in an off-mill furnace with a reducing atmosphere.
