Erosion, Abrasion & Rod Wear Protection
Endurance Technologies Inc. supplies field-proven, diffusion alloying technology (known as boronized tubing) - ENDURALLOY® - for the Oil and Gas industry and applications requiring superior tubing erosion abrasion and rod wear protection.
EndurAlloy® is eight to ten times harder than steel itself based on the Knoop or Vickers scale and is created through boron atoms in the gas phase, diffused into the steel substrate. The EndurAlloy® provides high integrity and erosion protection of the steel components’ surface that lasts three to ten times longer than regular bare steel production tubing.
The EndurAlloy® (boronized) surface layer provides excellent protection of Oil Country Tubular Goods (OCTG) and other components. EndurAlloy® provides erosion protection against rotating or stroking rod wear, sliding abrasion and erosion caused by:
- Fluids with abrasive particles
- Friction
- Corrosion
Or combinations causing premature failures caused by tube erosion. While maintaining original drift diameter, and possessing proven erosion protection and rod wear, ENDURALLOY® (boronized) production tubing dramatically reduces mean time between failure (MTBF) to significantly improve well run-time and well profitability.
Endurance Technologies Inc. (ETI) processes a wide variety of steel and types of components for equipment used in the Oil and Gas industry. Other EndurAlloy® (boronized) products include: Pup joints, casing, blast joints, sucker rod couplings, spool pieces, ESP stages, chokes, valves, fittings, pump (impellers, casing, stuffing boxes), frac nipples, down-hole tools, and many other assets where corrosion, rod wear or tube erosion is a problem.
Technical Benefits:
- Knoop hardness (HK0.1) 1600-1900 vs. 170-200 of bare steels
- Withstand elevated temperatures up to 400-450oC (depending on application situation)
- Stable low coefficient of friction during long friction modes
- No reduction of tubing ID
- ISO 9001 certified quality assurance
- Proven in-field performance
- Standard sizes available in 2-3/8”, 2-7/8”, and 3-1/2” (other sizes available upon request)
Common Boronized Tubing applications:
- Installed above rod pumps, PCP pumps and ESP pumps
- Multiple joints in deviated sections of the well-bore where excessive repetitive wear occurs
- Slant wells, directionally drilled wells and horizontal wells
- At Co-rod/Pro-Rod Connectors
- Severe corrosive environments
- Ideal for “problem” sections
