High Pressure Seals for Oil & Gas Upstream Equipment & Valves

High Pressure Seals for O&G Upstream Equipment and Valves

DuPont™ Kalrez® perfluoroelastomer parts and DuPont™ Vespel® parts and shapes in high pressure seal and valve applications help to reduce fugitive emissions, improve control in processing and provide excellent durability and resistance against chemicals and extreme temperatures.

Our solutions help our customers in a range of oil and gas industry applications to cut costs, improve efficiency and meet the highest health and environmental standards.

They are used in a wide range of applications for Exploration and Production operations (E&P) which include areas such as “downhole”, sub-surface and surface applications, and also in downstream applications through the various valves involved in handling sour services.

Kalrez® perfluoroelastomer (FFKM) parts are resistant to more than 1800 chemicals and solvents, and even resist sour multi-phase fluids. They retain high levels of elasticity and recovery, even after long-term exposure to harsh environments at elevated temperatures.

DuPont™ Vespel® Polyimide (PI) parts and shapes are manufactured according to the needs of each customer. Properties of Vespel® help overcome severe sealing, wear and friction challenges, can endure extremes of temperature (both cryogenic and high), and stand up to some of the world’s harshest operating environments.

In addition to polyimides offerings, the DuPont™ Vespel® CR series are a range of composite materials designed to perform in hostile chemical environments associated to the oil and gas industry, in particular high-pressure pumps and valves used in hydrocarbon processing and refining.

As a result, Kalrez® perfluoroelastomer parts and Vespel® parts and shapes have been shown to help reduce maintenance, and avoid interruptions in operations in a sector in which efficiency of production is paramount. Kalrez® and Vespel® parts have been proven in the field across the oil and gas industry and are found in such applications as:

  • Tubing to packer seals
  • Subsurface safety valves
  • Electrical insulation boots
  • Casting tie-back seals
  • Survey tool seals
  • Slip-joint seals
  • Mechanical seals
  • Ball valve seals
  • High pressure, high temperature seals (HPHT)
  • Backup rings
  • High temperature valve seats
  • Cryogenic valve seats
  • Centrifugal and reciprocating pumps
  • Reciprocating compressors.
