Corrosion Protection for Casing and Tubing
EndurAlloy® for casing and tubing provides corrosion protection whilst increasing run time, decreasing downtime and lasts three to ten times longer than regular production casing and tubing.
In even the most severely corrosive high pressure- high temperature water steam with salts, CO and CO2, H2S, acidic gases and water injection environments, EndurAlloy® (boronized) products stand up and perform to keep production moving forward.
Our field-proven diffusion alloying technology offers superior corrosion protection against rod wear and tube erosion. Corrosion can be caused by corrosive fluids containing sand and other abrasive particles which result in premature failure of bare steel tubing. More than 400,000+ joints (since 2010) of EndurAlloy® (boronized) Oil Country Tubular Goods have been deployed in the Global oil and gas industry. Most of these in wear and corrosive applications providing optimal results.
The EndurAlloy® (boronized) process can be applied to a wide range of equipment used in the Oil and Gas industry including: sucker rod couplings, ESP stages, centrifugal pumps (impellers, stuffing boxes), frac nipples, chokes, valves, fittings, pup joints and many other assets where corrosion protection is needed.
Technical Benefits:
- High corrosion protection and resistance in high pressure-high temperature water steam with high percentage of salts (e.g. NaCl), H2S, CO and CO2, hydrocarbons, produced water
- The EndurAlloy® case depth does not experience pits, separation, collapse, flaking, or disbondment which ensures a longer run life than the competition.
- Wire-lining, swabbing, pulling the pump & other down-hole operations will not damage the protected surface and create holidays in the surface where corrosive media can attack
- No corrosion caused by dissimilar metals
- No loss of inside diameter as with many “conventionally” coated tubing despite the formation of the protective iron boride layer up to 250 µm (0.010”)
- Base tubing is J55 or L80 1% Chrome; no special handling required for ID-treated product
- Standard sizes available in 2-3/8”, 2-7/8”, and 3-1/2” (other sizes available upon request)
Corrosion Protection Applications:
- Highly corrosive production environments: high pressure-high temperature steam, H2S, CO-CO2, chlorides, produced water
- Water source wells
- Acid gas injection wells
- Majority of acids and acidic environments, e.g. at elevated temperatures
- Basic (alkali) corrosive environments
