EL ULTRA-HIGH-STRENGTH SUCKER RODS
QUENCHED AND TEMPERED SUCKER RODS
Designed to provide an ultra-high load rating and successful corrosionresistant qualities, EL rods are Weatherford's premium line of highstrength coupled sucker rods. The exclusive induction case hardening process incorporated into the manufacturing of these rods makes them the ultimate fatigue-resistant sucker rod.
Designed for high strength and fatigue performance, the S88 rod provides an intermediate step between the normalized Grade D and ultra-high strength EL rod. These rods are manufactured with 3130M Nickel-Chrome steel; they are quenched and tempered which results in higher toughness and a finer grain structure, making them capable of better fatigue resistance. For example, the quenched and tempered rods typically have charpy impact results in the +70 ft. lb. range, while normalized and tempered rods are typically in the 20 ft. lb. range. This added toughness of the quenched and tempered rod provides the added fatigue resistance needed in extreme applications.

Ordinary sucker rods tend to fail from fatigue originating at the surface under tension. The unique engineering of the EL rod puts it in a class by itself. It has a thin compression layer at its surface that remains under compression even under normal operating tensile loads. Since the compressive pre-stress protects the surface from tensile stresses, the chances of developing fatique cracks are greatly reduced. Additionally, stringent quality control procedures employed with these rods promote reliable and long service life.

*Special High Torque Coupling and Make-up Procedures Required.
Weatherford Couplings Weatherford Grade “T” and “SM” sucker rod couplings are manufactured to strict quality control standards from high strength alloy steel and conform to API Specification 11B. The threads of these couplings are cold form-rolled produced by displacement of material rather than by removal of material as in the cut thread. Rolling the thread results in a compressive stress at the root of the thread, giving maximum strength to the traditional weak point of cut thread couplings.
Weatherford sprayed metal couplings have a corrosion resistant surface with a low coefficient of friction that reduces wear on the tubing and the coupling. This coupling is recommended for deviated wells. Weatherford couplings are available in Standard O.D., oversized and Slim Hole configurations in sizes of 5⁄8” through 1-1⁄8”.
T66/XD SUCKER RODS
API GRADE RODS
The T66/XD is an extremely dependable rod designed for high-strength service and provides an intermediate step between the Grade D and ultra-high-strength EL rod.
Weatherford API sucker rods are manufactured to API 11B specifications and ISO 9001/API Q1 certified in one of the most modern facilities of its type within the industry. These rods feature fully rolled, cold-formed threads designed to provided a precise, smooth, reinforced thread structure not attainable by normal machine-cut threads. Metal is displaced rather than removed, and the resultant cold working strengthens the thread root. Weatherford rods are cleaned by shot blasting to remove any scale and oxidation, then liberally coated with rust inhibitors and carefully palletized in bundles for safe transport and handling.
These rods are manufactured with 4138M chrome-moly steel, making them capable of handling the toughest stresses. The special alloy steel provides more resistance to sulfide stress cracking than AISI 4337 nickel-chrome-moly steel used in older generation high-strength sucker rods. The metallurgical makeup of the T66/XD sucker rods is checked continually for quality assurance. Rods are forged, normalized, and tempered, shot blasted, and pins precision machined and roll-threaded. This continuous in-process inspection confirms that only the finest sucker rods bear the Weatherford name. Applications Deep, highly loaded wells in mildly corrosive environments provided satisfactory corrosion inhibiting practices are followed.

Weatherford manufactures the COROD ® continous sucker rod for distinct production enhancement and cost saving advantages to various rod string applications. Unlike conventional sucker rods that are coupled every 25 or 30 feet, continuous sucker rods require couplings only at the top and bottom of the rod string-regardless of well depth. With fewer joints, this solid length of steel is lighter and enhances tubing life due to a more uniform contact between the tubing and sucker rod. It also addresses many premature tubing wear challenges, especially in directional and horizontal wells. SPECIAL APPLICATIONS Special applications such as highly deviated wells and heavy, highviscosity oil production, are prime opportunities for the high-strength, high-torque capabilities of the COROD® system.
Corod is ideally suited to both reciprocating and rotary pumping applications. For more information contact your nearest Weatherford Representative

Weatherford Couplings Weatherford Grade “T” and “SM” sucker rod couplings are manufactured to strict quality control standards from high strength alloy steel and conform to API Specification 11B. The threads of these couplings are cold form-rolled produced by displacement of material rather than by removal of material as in the cut thread. Rolling the thread results in a compressive stress at the root of the thread, giving maximum strength to the traditional weak point of cut thread couplings.
Weatherford sprayed metal couplings have a corrosion resistant surface with a low coefficient of friction that reduces wear on the tubing and the coupling. This coupling is recommended for deviated wells. Weatherford couplings are available in Standard O.D., oversized and Slim Hole configurations in sizes of 5⁄8” through 1-1⁄8”.

Weatherford API sucker rods are manufactured to API 11B specifications and ISO 9001/API Q1 certified in one of the most modern facilities of its type within the industry. These rods feature fully rolled, cold-formed threads designed to provided a precise, smooth, reinforced thread structure not attainable by normal machine-cut threads. Metal is displaced rather than removed, and the resultant cold working strengthens the thread root. Weatherford rods are cleaned by shot blasting to remove any scale and oxidation, then liberally coated with rust inhibitors and carefully palletized in bundles for safe transport and handling.

Weatherford manufactures the COROD ® continous sucker rod for distinct production enhancement and cost saving advantages to various rod string applications. Unlike conventional sucker rods that are coupled every 25 or 30 feet, continuous sucker rods require couplings only at the top and bottom of the rod string-regardless of well depth. With fewer joints, this solid length of steel is lighter and enhances tubing life due to a more uniform contact between the tubing and sucker rod. It also addresses many premature tubing wear challenges, especially in directional and horizontal wells. SPECIAL APPLICATIONS Special applications such as highly deviated wells and heavy, highviscosity oil production, are prime opportunities for the high-strength, high-torque capabilities of the COROD® system.
Corod is ideally suited to both reciprocating and rotary pumping applications. For more information contact your nearest Weatherford Representative

EL ULTRA-HIGH-STRENGTH SUCKER RODS
QUENCHED AND TEMPERED SUCKER RODS
Designed to provide an ultra-high load rating and successful corrosionresistant qualities, EL rods are Weatherford's premium line of highstrength coupled sucker rods. The exclusive induction case hardening process incorporated into the manufacturing of these rods makes them the ultimate fatigue-resistant sucker rod.
Designed for high strength and fatigue performance, the S88 rod provides an intermediate step between the normalized Grade D and ultra-high strength EL rod. These rods are manufactured with 3130M Nickel-Chrome steel; they are quenched and tempered which results in higher toughness and a finer grain structure, making them capable of better fatigue resistance. For example, the quenched and tempered rods typically have charpy impact results in the +70 ft. lb. range, while normalized and tempered rods are typically in the 20 ft. lb. range. This added toughness of the quenched and tempered rod provides the added fatigue resistance needed in extreme applications.

Ordinary sucker rods tend to fail from fatigue originating at the surface under tension. The unique engineering of the EL rod puts it in a class by itself. It has a thin compression layer at its surface that remains under compression even under normal operating tensile loads. Since the compressive pre-stress protects the surface from tensile stresses, the chances of developing fatique cracks are greatly reduced. Additionally, stringent quality control procedures employed with these rods promote reliable and long service life.
