Super Duplex Tubing from Fine Tubes Now Available with Enhanced Strength and Corrosion Resistance for Subsea Applications
Super Duplex tubes from Fine Tubes are now available for oil and gas and chemical process markets with enhanced capabilities for hostile, high-chloride applications.
The NORSOK M-650 approved tubing offers increased strength and corrosion resistance as compared with standard Duplex grades to deliver an extremely reliable product performance. These advantageous properties result in reduced production downtime and maintenance costs.
Other advantages include very short lead times, specialist non-standard specifications and the ability to create bespoke orders in small batch sizes. Super Duplex is available in
straight lengths that can be seamless cold redrawn and annealed in outer diameter sizes from 3mm (0.040 inches) up to 31mm (1.25 inches).
The versatility and enhanced capabilities of Super Duplex ensure that the tubing operates effectively up to 100,000psi for a range of demanding subsea applications. These include heat exchangers, flow meters, downhole pressure housings and smart wells, subsea Xmas trees and manifolds, injection and ballast water, and other critical oil and gas instrumentation applications.

Subsea 7 Completes Pipeline Bundle for Buzzard July marked the successful installation of a 5km Pipeline Bundle for the CNOOC International Buzzard Phase II (BPII) project.
Subsea 7’s 88th Pipeline Bundle in 40 years is now in the Buzzard field ready to link the new northern area wells back to the existing platform.
Subsea 7 was awarded the contract in 2018 for the project management, engineering, procurement, construction and installation of the Bundle, along with associated well and platform tie-ins.

Bundle technology is an ideal fit for this project. It provides all subsea production, water injection and gas lift flowlines, as well as control functions and end manifolds in a single integrated system, which is fully fabricated and tested onshore. The BPII Bundle system also incorporates a large drill centre manifold (36m long and 300 tonnes), allowing for up to 12 wells to be tied-in.
Fabricated and launched from Subsea 7’s Wester fabrication site near Wick, Scotland, the complete 5,500 tonne system was towed 150km to the Buzzard field using a specialised mid-depth tow method.
This is the latest in a series of major achievements for the project which is being delivered using an innovative Alliance model. Last month saw the installation of the new topside module, with Subsea 7 working closely with Allseas and fellow Alliance members CNOOC International and Worley. This is an example of how Alliance contracting models can be used to maximise collaboration on projects to deliver superior outcomes.
tube systems are subjected to some of the most corrosive and hostile subsea conditions. Standard alloys corrode quickly, incurring re-fitting costs and production downtimes and delays. Our Super Duplex tubes are custom-engineered to meet the stringent industry requirements and offer greater corrosion resistance for aggressive environments that demand total product reliability.”
Fine Tubes operates out of Plymouth, UK. It is one of five business units that make up AMETEK Specialty Metal Products (SMP), along with Superior Tube, Hamilton Precision Metals, AMETEK SMP Eighty Four and AMETEK SMP Wallingford.
