Oil & Gas Upstream Subsea Tubing Applications and Capabilities

 

The coiled tubing (CT) industry is a major part of oil & gas upstream subsea applications.  Coiled tubing is used widely in extreme conditions in offshore environments. The North Sea is a  good example of extreme offshore applications. Extreme conditions require a special grade of seamless stainless steel tubing known as 6 Mo (UNS S31254).  Common applications include interventions in wells or for production tubing  to extend the life of “depleted wells”.  Interventions are operations performed in oil wells during production or at the end  of a well’s useful life.  The process of intervention changes the condition of the well or its structure, and can be used for well diagnosis or to assist controlling production.

The 300 Series | Seamless Stainless Steel Tubing

The most common seamless stainless steel tubing is the 300 series of alloys, which are available in varieties of high-performance, corrosion-resistant types and sizes. These stainless steel alloys most commonly include chromium, nickel, molybdenum and titanium, and are ideal for seamless coil tubing because they are easy to maintain and can withstand high pressures and temperatures.

Seamless Tubing for Firefighter Air Replenishment Systems (FARS)

Firefighters face many dangers in the line of duty.  Among the greatest dangers are injury or loss of life from heat exposure or from running out of air.  To access breathing air during a fire, firefighters are trained to use SCBA (self-contained breathing apparatus). The tanks they carry on their backs are their lifeline. If a firefighter runs out of air while fighting a fire, he or she very well may not make it out alive.
