Close Dimensional Tolerance SS Hydraulic Tubing Capillary Tube for Hydraulic Control and Chemical Injection
Product Description:
Meilong Tube offers tubing products for the oil & gas sector that have been successfully applied in some of the toughest subsea and downhole conditions. We have a long proven track record of supplying products that meet the strict quality requirements of the oil and gas sector. We offer coiled tubing in a wide range of corrosion resistant stainless steels, nickel alloys. From the technical advances of 1999 to the deepwater challenges of today, we have extensive experience in this sector.
One of the main challenges for the upstream extraction of oil and gas is to protect pipelines and process equipment against waxes, scaling and asphalthane deposits. The engineering disciplines of flow assurance play a key role in mapping these requirements, and coiled tubing from Meilong Tube can be applied to umbilicals and chemical injection systems, improving effectiveness when it comes to chemical storage and delivery.
Our tubing is designed with integrity and quality in mind, particularly for its use in subsea conditions for the oil and gas industries. We manufacture corrosion resistant alloy hydraulic control line tubing products for a variety of upstream oil and gas and geothermal applications. Our specialties include duplex, nickel alloy and stainless steel grades, customized to each customer’s specific requirements. With this, we are certain that our tubing can successfully perform in the aggressive subsea and downhole environments.
Features:
Meilong Tube is located in a complex of buildings that amounts to 20,000 square meters. To produce the tubes that they manufacture, Meilong Tube created their own tube mills. These tube mills are used to form tubing, and weld the tubing using gas-tungsten arc and laser beam. There is also a cold working process called sinking, which takes place when the tubing is pulled through a lubricated die. For some tubing dimensions, welding duties may not be possible, and so floating-plug operation is needed in order to control the inside diameter of the tubing. Lastly, the tubing must be heat-treated, so an off-mill furnace with a reducing atmosphere is employed.

Applications:
Meilong Tube’s long length alloy tubing in coils are used extensively for a variety of applications, including hydraulic power, single transmission, monitoring and control equipment, chemical injection lines, downhole and subsea safety valve control, umbilical control lines, topside instrumentation and impulse lines, wellhead control panel, and downhole gauge cable.
These tubing coils offer a range of advantages, such as short hydraulic response time, greater collapse strength, and elimination of methanol permeation. Additionally, the long length of the coils is continuous without orbital welds, reducing the potential for weld-related defects and failures. Clean and smooth ID surfaces provide optimal performance in hydraulic and chemical injection systems.
