What makes Endurance Technologies better than the competition?

It’s simple: We last longer. No other commercial products can perform so well in a highly abrasive or corrosive environment. Our tubing with the EndurAlloy™ protective layer can withstand the heaviest wear and corrosion conditions occurring in oil production. In areas with well deviations, dog legs, side loading, pump discharge, or in highly corrosive environments with high H2S and CO/CO2 concentrations, our tubing simply lasts longer.

What is EndurAlloy™? How does it work?

EndurAlloy™ is a surface engineering thermo-chemical (thermal-diffusion) process based on the CVD principles where boron atoms, being in the gas phase, deposit and diffuse into the heated steel surface with consequent formation of iron borides (FeB and Fe2B) with their growth and consolidation yielding a hard and chemically inert protective layer. It is also often referred to as diffusion alloying and pack cementation.

How does EndurAlloy™ Tubing save on down time and money?

Typically, EndurAlloy™ Tubing lasts 3 to 10 times longer than regular steel tubing, depending on various well conditions and production system design. The savings you achieve by avoiding your first service rig job and its associated down time will provide an ROI many times over the cost of the EndurAlloy™ tubing itself. In fact, it is common to avoid several rig jobs.

What is the major difference between EndurAlloy™ and many conventional coatings?

EndurAlloy™ is a surface engineering advanced coating where, similarly to CVD coatings and as opposed to many “conventional” coatings, the protective layer forms as a new compound through the combined thermo-chemical reaction, diffusion, and high-temperature consolidation processes. We use a special composition of powders, mixed to create through the gas phase, the protective layer with “new” composition occurring with contact with steels or ferrous alloys at high temperatures. As opposed to many conventional coating processes, the diffusion-related bonding provides excellent adhesion of the iron boride layers to the substrate with no delamination or peeling-off.

Does EndurAlloy™ Tubing maintain the mechanical properties of J55 Tubing?

Throughout our process on average the tensile and yield properties of J55 tubing remain within API specs.

How can EndurAlloy™ be both very hard and highly resistant to corrosion?

Resulting from the thermal diffusion process, the EndurAlloy™ surface is a well consolidated layer consisting of iron borides with high hardness and high chemical inertness. It is highly resistant to many corrosive gases and liquids, e.g. to many acids, alkalis, high temperature-high pressure water steam with high contents of salts, H2S, CO, CO2, hydrocarbons, etc. We have various test documents to support the corrosion resistance of our products.

Are there any special handling requirements for installing ID processed EndurAlloy™ Tubing?

No.  When EndurAlloy™ tubing is processed on the inside surface only, it can be installed with exactly the same equipment as regular steel tubing.

Can EndurAlloy Tubing also be processed on the external surface?

Special order EndurAlloy™ Tubing can be processed on the external surface for additional corrosion protection or for use as blast joints. However, due to the EndurAlloy™ surface, externally processed tubing has special handling requirements. Contact us and we can share the necessary handling procedures available to run this product.

Can EndurAlloy™ be applied to other products?

The EndurAlloy™ 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 (cases, impellers, stuffing boxes), frac nipples, chokes, valves, fittings, pup joints, as well as various piping systems, elbows, reducers, cyclones and many other items where erosion, abrasion, friction, or corrosion are a problem.

What are the turnaround times for EndurAlloy™ products?

Endurance Technologies carries an inventory of EndurAlloy™ Tubing at our Calgary yard as well as yards throughout Saskatchewan (Kindersley, Swift Current, Estevan) and Alberta (Provost, Brooks, Elk Point, Spruce Grove, Bonnyville , Lloydminster, and Whitecourt). For special orders (4 ½” and above), turnaround times are 3-5 weeks. Please contact Sales for yard contacts.

Can the EndurAlloy™ surface be machined?

It is not recommended since the new surface is extremely hard, and its machining can be done only using expensive special diamond tooling and dedicated processing.

Can I weld to an EndurAlloy™ surface?

Please contact our office for details.

What materials can be processed?

All carbon and low-alloy steels, majority of stainless steels (e.g. 300 and 400 series stainless steels), Ni-rich ferrous alloys, 17-4ph, cast steel and forged steel, as well as cast irons. We have other processes that can be used on other materials. Depending on substrate material and process parameters selected, the case depth varies from 0.001” to 0.012” (25 to 300 µm). Please, contact our office with your specific requirements.
