Control Line Tubes

Control line and chemical injection line tubing in seamless or welded condition. Merinox can supply from 3 – 8 mm in Metric and 1/8” up to 1” OD in Imperial, with a variety of wall thicknesses, in loose bulk wound coils or level wound wooden, plastic or metal reels.

We can supply in the following alloys: 316L, 316Ti, 317L, Duplex, Super Duplex, 400, 600, 625, 825 and C276.

To be used for a number of petrochemical applications, including:

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

Down Hole & Umbilical Tubing

Our long-length seamless coils up to 1,200m (4,000 FT) are used extensively for chemical injection and hydraulic control in subsea and offshore wells. The long lengths          minimise 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.

Encapsulated Control Lines

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