Control line tubing

Are you interested in control line and chemical injection line tubing in seamless or welded condition? Merinox is the tubing specialist that offers high-quality tubes in various materials, colours, and thicknesses. We supply tubing from 3 – 8 mm (1/8” till 28,4 mm / 1” OD) and in a variety of wall thicknesses. You can buy our tubes in loose bulk wound coils or level wound wooden, and with plastic or metal reels.

The applications of control line tubing

At Merinox, you find control line tubing in the alloys:

Our control line tubing can be used for numerous petrochemical applications, including:

  • Down hole tubes;
  • Subsea umbilicals;
  • Process constructions;
  • General control system;
  • Steam supply lines;
  • Gas transport lines;

Down hole and umbilical tubing

We provide long lengths of seamless tubing up to 1500 meter (5.000 Ft) without orbital joints, depending on product dimensions. You can use them extensively for chemical injection and hydraulic control in subsea and offshore wells. The long lengths minimize the number of orbital welds, which reduces the potential for weld-related defects and failures. Additionally, our coils have an extremely clean and smooth ID surface that is ideal for hydraulic and chemical injection systems. With orbital welds, our coil lengths can be up to 15.240 meters (50.000 Ft) level worded on one metal reel.

Encapsulated control line

Merinox offers the encapsulation of control lines to provide increased durability, as well as chemical and corrosion resistance to meet each project’s specialized requirements, we offer different pre-insulated tubes, such as: HDPE (High Density Polyethylene), Santoprene, PVC (Polyvinyl Chloride), Haylar and PVDF (Polyvinylidene Fluoride).
