  • Instrumentation

Down hole & umbilical tubing

Our long length seamless coils up to 1500 mtr (5.000 Ft) without orbital joints depending on product dimensions,
are used extensively for chemical injection and hydraulic control in subsea and offshore wells. The long lengths
minimizes 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 mtr. (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 encapsulation types, such as: HDPE (High Density Polyethylene), Santoprene, PVC (Polyvinyl Chloride), Haylar and PVDF (Polyvinylidene Fluoride).
