API and HighStrength Rods Full-Integrated Manufacturing Process

Both the API and the high-strength sucker rod lines are manufactured by means of a rigorous quality assurance system that complies with ISO 9001:2000 and API Q1 standards.

From the production of steel as raw material to the production of the sucker rods, the entire process takes place in Tenaris’ plants. Within these plants, Tenaris produces the entire line of API sucker rods, progressive cavity pumping (PCPRod®) rods and its range of premium connection products. They efficiently respond to extreme conditions such as high loads, corrosive environments and applications where tubing-rod friction control is required.

Both API and high strength sucker rods are manufactured from high-quality steel bars. During the manufacturing process all of the rods are straightened and inspected superficially over their entire length by a set of Non Destructive Testing (NDT) equipment that verifies the presence of transversal and longitudinal defects, if any, in accordance with API criteria. Internal US (ultrasonic) tests are also performed.

During the forging process, the rod ends are heated in induction furnaces, so that the ends can then be shaped in successive forging passes. This ensures optimal fatigue resistance of the forged zone.

Tenaris is the only company in the world that manufactures sucker rods and couplings in a fully integrated way. In its plants in Argentina and Brazil, it develops special products for each type of need.

After being inspected they are thermally treated over their entire length in specially designed furnaces to obtain uniform mechanical and metallurgical properties throughout the rod. The high-strength rods undergo different thermal treatments, depending on the desired grade, in order to obtain the specified metallographic structure and mechanical properties.

Once the rods have been thermally treated, they undergo a shot pinning process that compresses the external fibres thereby improving fatigue resistance. Before machining, the rod ends are inspected on a bench. Machining and threading processes are performed in state-of-the-art CNC (Computerized Numeric Control) equipment which allows an excellent surface finish on the joint seals. Threads are obtained by means of cold rolling to ensure greater fatigue resistance. Finally, before packaging, the rods are protected with an oil-soluble paint that prevents the oxidation during transport and storage.

High-Strength Sucker Rods Greater mechanical strength: used for deep wells and/or high loads. ! Full scale testing lab. Campana, Argentina.

Tenaris has a line of high-mechanical-strength rods with three different options to suit different service conditions. Ultra High-Strength (UHS-NR) Sucker Rods The UHS-NR sucker rods is one of the alternatives available, manufactured in AISI 4330 Mod. alloy steel. Its mechanical properties are obtained through a normalized and tempered heat treatment, which allows the rod to reach flow and breaking properties above the API standards. Due to its greater fatigue resistance, it can reliably increase the extraction depths and flow rates. It is recommended for non-corrosive wells with very high loads.

Plus Rods The Plus sucker rod is another alternative for high loads. This product undergoes an induction-based surfacetempering heat treatment. This process generates a binary structure where the external surface is quenched whereas the core remains untempered. Since the external layer has lower density (martensite) than the core, a permanent state of compression is produced in the periphery, which is the determining factor for high fatigue resistance.

Maximum Stress (ksi)

It is recommended for services in deep wells with high flow rates effectively inhibited.

High-Strength Sucker Rods, Critical Service (MMS-NR) This product is manufactured in a specially developed steel to provide the required high mechanical strength, but reducing susceptibility to hydrogen-induced embrittlement (SSC – Sulphide Stress Cracking). This is a phenomenon increasingly present in wells under secondary recovery by means of water injection. It is a chromiummolybdenum alloy steel that contains no nickel. Its heat treatment is normalized and tempered. It is recommended for services in deep wells with high loads, and inhibiting is recommended to improve its performance.

! Joints with a contact surface with special roughness and perpendicularity.

Accessories A broad range of products of the highest quality to complete the pumping string. API Couplings: T and Spray Metal The couplings are manufactured from seamless steel pipes produced by Tenaris. The T and Spray Metal (SM) couplings combine the steel quality with the cold-rolled thread, which gives them greater fatigue resistance. Spray Metal is a superficial hardening process in which a nickel, chrome, boron and silicon based powder is applied on the base metal and later melted, resulting in a hard, dense and uniform surface with a very low friction coefficient and high corrosion resistance.

Coupling machining is performed in modern CNC (Computerized Numeric Control) lathes for both types of product. The entire line of class T, Spray Metal, combination couplings (cross over couplings) and polished rod and sinker bar couplings are produced in reduced SH (slim hole) diameters as well as in the normal FS (full size) diameter. Pony Rods In compliance with the same quality requirements applicable to the rods, pony rods measuring 1, 2, 4, 6, 8, and 12 feet are available for each steel grade and diameter. Other lengths are also manufactured in accordance with customers’ specifications.

High-Strength Couplings (UHS) This product was developed to address customers’ need to solve the growing problem caused by fatigue breaking in couplings, mainly in wells using high-strength rods or in wells using reduced diameter SH (slim hole) couplings. The couplings are manufactured from alloy steels with quenching and tempering heat treatment. Their design allows them to withstand high loads during well service. They are recommended in combination with any highstrength or Grade D sucker rods, working under very high load conditions.

! Sinker bars.

! Polished rods.

Sinker Bars This product is necessary in order to maintain an optimized string design, so as to avoid premature failures in the installation. It is very effective for reducing failures in the rod body, pins and coupling, which occur due to the effect of compression and buckling in the string.

Polished Rods Tenaris offers several types of low- and medium- alloy steel polished rods with an excellent surface finish to ensure the proper seal in the stuffing box.

Special Products Special solutions to increase rod string life and performance. Rod Guides Tenaris has a wide range of rod guides and materials for both, rod pumping and PCP. Tenaris offers different materials adaptable to different fluid conditions, as well as to high or low bottom-hole temperatures. These guides are injected directly on the rods, which impart a high degree of separation resistance, reducing the probability of displacement and thus becoming a true protection for the tubing and for the rod itself. It has been proved that their use in wells significantly increases the life of the tubing and of the rods, reducing wear with a consequent reduction in repair interventions and other operating costs. Combined with the use of rod rotators, they also allow effective paraffin control.

! Guides for PCP at low temperatures.

! Guides for beam pumping at high temperatures.

The sinker bars are located at the end of the string, above the pump, to keep it fully subjected to tensile loads during the pumping cycle. This minimizes the compression generated on the rods during the pumping downstroke.

For corrosive services, stainless steels in the AISI 304 and 316 series are available, as well as steels with hard chrome and Spray Metal coatings. Their alternatives are manufactured in various lengths and diameters of 1 1/4” and 1 1/2”, according to customer’s specifications.

They are manufactured in compliance with the API standard in diameters from 1 1/4” to 2” in steels at the customer’s request, with breaking strengths of 65,000 psi or 90,000 psi. A proprietary design alternative is also available in 1 1/8” with a 7/8” pin, for wells with 2 7/8” tubing, pumping high flow rates.
