Meilong Tube: Specialized Tubing for Unique Needs

Meilong Tube is a market leader in manufacturing seamless and redrawn, welded and redrawn coiled tubing. These are made with the highest quality corrosion-resistant austenitic, duplex, super duplex stainless steels, and nickel alloys. Most commonly used as hydraulic control lines and chemical injection lines, they are specifically designed for oil and gas, geothermal industry usage.

What makes Meilong Tube unique is its ability to produce the longest continuous chemical injection line tubing available in the stainless steel and nickel alloy marketplace. These long length tubing coils are used extensively for chemical injection in both subsea and onshore wells, and boast a reduced risk for defects and failure. Benefit from short hydraulic response times, greater collapse strength, as well as preventing methanol permeation. Clean and smooth inner surfaces make them ideal for chemical injection safety and efficiency.

2205 Duplex Stainless Steel: the Work Horse Grade

Developed to combat common corrosion problems in 300 series stainless steels, 2205 duplex stainless steel is a nitrogen-enhanced duplex stainless steel. It's a combination of a ferritic alloy (exhibiting stress corrosion cracking resistance and high strength) and an austenite alloy (ease of fabrication and corrosion resistance). It is made up of 40-50% ferrite in annealed condition.

Due to its nitrogen content, 2205 duplex stainless steel shows higher corrosion resistance to chloride pitting and crevice corrosion. It has a wide variety of applications in many areas including marine services, brackish water, bleaching operations, closed loops, and food processing. In these areas, 2205 duplex stainless steel outperforms common stainless Steels like SS 316L and SS 317L.

However, usage should be limited to temperatures below 600°F. Prolonged elevated temperatures may embrittle the 2205 duplex stainless steel.



Each one tubing coil is a continuous length with no orbital welds. Its quality is guaranteed by hydrostatic testing at a minimum of 10,000 psi; such a test can be attended by third-party inspectors.

In order to check material quality, Meilong Tube performs a series of tests, including eddy current test, chemical tests, flattening, flaring, tensile, yield, elongation, and hardness. Vacuum annealing for injection lines is also implemented as it ensures volatility of metallic oxides and removes residual degreasing solvents or drawing lubricants.

The benefits of using Meilong Tube's products are evident: close dimensional tolerances, superior mechanical properties, superior surface finish, high cleanness of inside surface, and controlled ovality and eccentricity.


Technical Parameters:

We have seam-welded and floating internal plug redrawn tubing in Duplex 2205 grade which is available in the annealed condition. It comes in continuous lengths without orbital joint welds.

We are providing the following steel characteristics to outline the tubing performance better:

  • Alloy: UNS S32205
  • Outer Diameter (O.D.): inch
  • Wall Thickness (W.T.): inch
  • Working Pressure: Psi
  • Burst Pressure: psi
  • Collapse Pressure: psi
  • Test Pressure: psi

Also, the theoretical burst pressure and the theoretical collapse pressure are based on minimum wall thickness and minimum tensile strength or minimum yield strength respectively. The pressure rating based on 100°F (38°C), neutral and static conditions. Besides this, the working pressure is based on 100°F (38°C).



Coiled Alloy Tubing Manufacturing and Applications

We manufacture coiled alloy tubing for a wide range of industrial and engineering uses. This includes capillary tubing for chemical injection, bare and encapsulated hydraulic control line tubing for subsea safety valves, and velocity strings, work strings, and steel tube umbilicals.

We specialize in producing coiled alloy tubing for specialized applications such as Geothermal uses. Our coiled tubing is manufactured with the highest quality alloys to deliver superior performance and longevity in even the toughest industrial and engineering applications.

We emphasize creating strong relationships with our customers to develop customized solutions that meet their unique needs. We also have a highly trained and experienced team of engineers and technicians who are dedicated to providing the highest customer service for our clients.
