Application

Oil and Gas: Subsea

Sub-Surface Safety Valves (SSSV) / Umbilicals: Tubes filled with Hydraulic Fluid which run from floating platform or FPSO to the well head on the sea floor.

 

Oil and Gas: Downhole

Downhole Control Lines: Tubes running from above ground surface controls into a downhole well to the location of the well’s safety valve.

 

Geothermal

Calcite Inhibition System: Carries chemicals into earth’s crust to flash point of water in a geothermal well; injected to break down calcite deposits and extend life of the well.

 

Instrumentation

Common connection tubing for control panels, pneumatic equipment, and fluid lines.

 

Since 1999, Meilong Tube Co., Ltd. has produced long coils of stainless steel and high nickel alloy tubing for numerous oil and gas applications, including hydraulic power, monitoring and control equipment, instrumentation, injection lines, down-hole safety valve control, subsea umbilical applications. Unique manufacturing capabilities and processes allow Meilong to produce the longest continuous length control line tubing available in stainless steels and high nickel alloys.

 

Our coiled tubing is available in a number of high performance corrosion resistant stainless steels and high nickel alloys, including 300 series, Incoloy, Inconel, capable of withstanding a variety of severe environmental conditions.

 

We specialize in manufacturing small diameter tubing ranging from 0.125 inch to 1 inch outside diameter (3.18mm to 25.4 mm) and a variety of wall thickness. All tubing is level wound coiled on various size spools, and products are tested and evaluated for specific applications before delivery. Our engineering staff welcome the opportunity to work with customers to solve special problems.

 

Meilong’s seamless control line tubing is drawn from seamless extruded tube hollows to ensure absolute product safety and reliability. Our seamless line tubing is one continuous length of tubing, completely free of any welded joints or seams. Long length coils reduce installation time and costs by eliminating the need for excessive joints preparation and fittings. Elimination of excessive fittings increase reliability and assures a leak-free system. We are capable of 100% hydrotesting each coil.

 

In meeting customer’s requirements, our tubing can be encapsulated in various materials such as thermalplastics, nylon and PVDF. Coiled seamless control line tubing offers many advantages to installers of hydraulic or pneumatic lines on offshore platforms and onshore refineries. It offers unmatched safety and reliability, while at the same time reducing the frequency of costly joint connections. Close tolerance control during manufacturing assures easy insertion and connection to fittings due to tubing’s inherent ductility.

 

Downhole hole & umbilical tubing

Our long length seamless coils are used extensively for chemical injection and hydraulic control in subsea and onshore wells. The long length minimizes the number of orbital welds which reduces the potential for weld-related defects and failures. Additionally, our coils have an extremely clean and smooth ID surface that is ideal for hydraulic and chemical injection systems. Seamless stainless steel coils offer short hydraulic response time, greater collapse strength, and elimination of methanol permeation.

 

Vacuum annealing

Meilong takes special care during manufacturing to assure ID and OD cleanliness of control line tubing. Vacuum annealing insures volatility of metallic oxides and removal of any residual degreasing solvents or drawing lubricants. Vacuum annealing our stainless steel tubing insures a bright, cosmetically appealing surface as well as excellent mechanical properties.

 

Meilong commitment to quality excellence

From the time an order is received, sent through the production process, completed, and finally shipped, many levels of inspection occur to reinforce Meilong’s Quality Policy. The job of ensuring quality products extends as far as our machine operators. Meilong operators take ownership over material processed at their stations by measuring for dimensional accuracy and conducting a visual inspection of every piece.
