Industries - Energy Upstream

Securing the Future of Energy Infrastructure


Years of experience designing solutions for the Energy industry.

We design products and materials for the safety and consistency of operations in the oil & gas, petrochemical, and power generation industries.

Collaboration with our customers delivers quality solutions. Our engineers apply their expertise from prototype testing to validation and production of finished parts.  We test our materials to 37 internationally recognized test methods, so our products are verified consistent and reliable.

Expert Application Engineering

Superior Designs

Safety and efficiency drive innovation in Greene Tweed thermoplastic composite wear parts. Our application engineers understand the industry standards for refineries, chemical plants, and power generation plants. And they develop our products to sustain rotating equipment like pumps and compressors. 

The non-galling, non-seizing performance and chemical resistance of our WR® (Wear Resistant) composites cut down wear and friction.

Our AR® (Abrasion Resistant) composites reduce downtime for pumps handling media-containing solids. These composites resist the most extreme abrasion effects for a longer product life.

Optimized Valve Sealing

Extend service life, enhance equipment reliability, reduce cost of ownership. Greene Tweed sealing solutions for valves withstand the extreme conditions of the oil & gas, petrochemical, and power industries.

We build our sealing solutions for  valve seal applications from range of high quality materials:

  • Chemraz® Perfluoroelastomers (FFKM)
  • Xyfluor® elastomers
  • MSE® lip seals
  • Arlon® and Avalon® engineered thermoplastics

Powerful Industry Benefits

Fast delivery, increased reliability, reduced cost of ownership and reduced bad actor equipment. These are select benefits that our mechanical seals offer to market leaders. Industry-tested and industry-proven, our mechanical seal solutions withstand upset conditions and enable standardization.

Secondary seal designs combine our elastomeric materials like  Chemraz® FFKM and Fusion® FKM and thermoplastics like  Avalon® and Arlon®.  These seals wipe out process contamination and reduce maintenance.

Designed to Last

Greene Tweed drilling and completion tools withstand extreme temperatures. They bear the pressure of energy operations. And they resist the effects of corrosive chemicals. Our solutions extend system life and reduce maintenance in well applications.

Seal-Connect® connectors outlast the performance of traditional glass-to-metal technology. And our solutions ensure consistent, reliable measurement while drilling (MWD), logging while drilling (LWD), directional drilling, and wireline operations.

Sealing Solutions for Any Application

While pumps, compressors, mechanical seals, and valves are our primary application focus, Greene Tweed develops solutions for many other types of energy applications.

Look for a wide range of our materials in production equipment like surface and subsea trees, wellheads, liner hangers, SSSVs, subsea risers, and ESPs.
