Kevlar® for Oil & Gas Applications

Kevlar® for Oil & Gas

For more than 40 years, DuPont™ Kevlar® has continued to help innovate in applications for the oil and gas industry.

Kevlar® in Offshore Hoses and Pipes

The strength of Kevlar® brand aramid fiber helps offshore oil facilities to carry out vital operations. In umbilicals — bundles of high-pressure hydraulic hoses that run from the top of a drilling platform or production facility down to control the equipment on the ocean floor — Kevlar® is the primary strength reinforcement that helps enable the use of flexible thermoplastic hoses instead of steel tubes. Kevlar® is also used to help reinforce the risers, the pipes that carry the oil from the ocean floor back up to the production platform. Combined with its chemical and corrosion resistance properties, the resistance of Kevlar® to elongation under load and “creep” — incremental elongation distortion over time — helps make it particularly well suited for the rigors of offshore oil extraction and production.

Kevlar® in Onshore Piping

Kevlar® fiber is also suitable to use as the reinforcement strength member of small diameter thermoplastic pipes (RTP) for onshore applications, helping to enable higher pressure ratings than unreinforced pipes. The reinforced thermoplastic pipe can be produced in long continuous lengths and coiled for transport to the installation site. The corrosion resistance of a thermoplastic pipe makes it an excellent alternative to steel pipe. An RTP solution will have a lower installation cost and longer lifetime in corrosive environments than steel pipe.

Kevlar®: Putting New Life into Old Pipes

The developed world is crisscrossed with pipeline networks, and many are close to the limit of their working life. Energy suppliers, industry, and public utilities face spiraling costs of replacing pipe networks with corroding steel. Conventional methods of repair or replacement are expensive and disrupt supply and surrounding infrastructure, especially in urban areas. Innovative use of DuPont™ Kevlar® brand fiber, however, helps enable the trenchless renovation of many different kinds of pipeline in a fraction of the time necessary for conventional repair or replacement. Downtime and disruption are minimized. Cost savings can be enormous. Kevlar® fiber helps offer tomorrow’s solution to the limitations of yesterday’s technology: flexible, high-pressure plastic pipes that restore the efficiency of aging pipe networks. In effect, a new pipeline is inserted within the structure of the old. Its tough, flexible construction enables it to be fed around bends and through long lengths up to 2,000 meters. Pipeline diameter is virtually unchanged, so there is no loss of volumetric flow. The inner liner is entirely self-contained — the old pipe is only used as a route, so its continuing deterioration is irrelevant.


  • Kevlar® Fibers

    DuPont™ Kevlar® fibers are used to help provide strength, flexibility, and lightweight protection in everything from yarns and woven ballistic fabrics to ropes and apparel.


  • DuPont™ Kevlar® brand aramid fiber helps save lives and also helps strengthen eq
  • Kevlar® brand

    Best known for its use in ballistic and stab-resistant body armor, Kevlar® brand aramid fiber is credited with helping to save thousands of lives. Lightweight and extraordinarily strong, it’s used to make a variety of clothing, accessories, and equipment safer, more cut resistant and durable.


  • Trenchless Pipe Rehabilitation with Kevlar®

    The Primus Line® pipeline system developed by Rädlinger uses the strength of DuPont™ Kevlar® fibre for trenchless rehabilitation of pressure pipes. Designed with short rehabilitation times and fast recommissiong in mind, Primus Line® offers substantial potential savings as a viable alternative to open rehabilitation methods.

  • Kutting UK Offshore Oil & Gas Hoses

    Kutting UK Ltd., a leader in the manufacture of thermoplastic high pressure hoses for the offshore oil and gas industry, recently decided to switch all its aramid-based products to DuPont™ Kevlar® brand fibre, helping their company to develop the next generation of very-high-working-pressure-, high-temperature- and high-collapse-resistant hoses demanded by the industry.

  • Nexans Underwater Cables with Kevlar®

    To manufacture underwater cables rugged enough to protect delicate fibre optic lines against the drag force exerted by kilotons of salt water, Nexans makes extensive use of DuPont™ Kevlar®, an aramid fibre which is five times stronger than steel on equal weight basis.
