About Us

Meilong  manufactures high quality seamless and redrawn, seam-welded and redrawn coiled  tubing which are made from corrosion-resistant austenitic, duplex, super duplex  stainless steel and nickel alloy grades. 100% of products are used as hydraulic  power control lines, chemical injection lines, alloy tubing in umbilicals and  instrumentation tubing for the exploitation engineering in the upstream oil and  gas industry.

Coiled  tubing is available in sizes arrange from outer diameter 0.125 inch (3.175  millimeters) to 1 inch (25.4 millimeters). Wall thickness is up to 0.165 inch (3  millimeters). Lengths up to 32800 feet (10,000 meters) are available for  cost-effective umbilical manufacturing. More sizes within the scope can be  customized to be produced and delivered for meeting your special requirements.

As more  oil and gas extractions move into deeper and harsher waters where extreme  offshore environments demand extreme safety, our work is to help you use the “right”  corrosion resistant material for coiled umbilical tubing to improve the safety and  reliability of your work. This is the power for driving our innovations and  continuous development.

Now Meilong  is devoting its capability to bring global customers most cost-effective tubing  products through ensuring a comprehensive supply guarantee regarding the complete  value-added chain in tubing production and is herewith the basis for the high performance  in products and customer satisfaction.
