Meilong Tube has taken multiple initiatives to bring technological advancements to the industry, a prime example being raised length for tubing fabricated without the help of orbital welds. Additionally, Tube Encapsulated Conductors (TEC) were also introduced by our company to the oil and gas industry.
To deliver superb equipment and exceptional customer care, Meilong Tube has assembled a highly capable management team with remarkable industry expertise. Representing a combined vast experience in the tube production and customer service field, these professionals guarantee that our clients obtain personalized outstanding quality solutions to all their tubing requirements.
The ambition of Meilong Tube is to, if not exceed, then at least reach the expectations of our customers in regards to product caliber, business conduct, and the diligence of the support staff. Our customer's gratification is our utmost priority here at Meilong Tube, and always will be.
Our hydraulic control line technology is free from orbital welds. Thanks to improved completions, we no longer need to rely on mill-produced coils.
We use Tungsten Inert Gas (TIG) and laser beam welding machines to achieve a highly repeatable weld with superior quality. With the combination of our welding machines with cold-drawing machines, we are able to achieve OD sizes from 1/8” – 1” and wall thicknesses from 0.028” -0.095”.
Common alloys for our tubing products that we work with are 316L, Duplex 2205, Super Duplex 2507, Incoloy 825, and Inconel 625.
This type of tubing, which comes in an annealed condition and in continuous length without orbital joint welds, is engineered using Duplex 2205 UNS S32205. It is designed to adhere to the following specifications for O.D., W.T., Working Pressure, Burst Pressure, Collapse Pressure and Test Pressure:
