Product Details
SGS / BV Inspected Seamless Chemical Injection Line Capillary Tubing with Continuous Length
Meilong Tube 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 0.083 inch (2.108 millimeters). Lengths up to 65600 feet (20,000 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.

- Theoretical collapse pressure based on minimum wall thickness, and minimum yield strength
- Pressure rating at 100°F (38°C), neutral and static conditions
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.
Suitable for Application Environment
A common resitance to chloride pitting, crevice corrosion, H2S and CO2, and chloride stress corrosion cracking (SCC).
