D. Circulating Type Chokes for Nipples (Product Code 20)

Circulating Chokes restrict fluid flow in the tubing string and permit circulation from above, making them the tool of choice for flow measurement and production rate management. The restriction is created by a Bean (designated by a 64ths-of-an-inch orifice) seated in the choke body; a wide range of orifice sizes is available, allowing the operator to calibrate the flow rate to the well's specific requirements. Circulating Chokes are also commonly used to reduce production intentionally when full-rate flow is not desirable. Types available include ROTAX, ROTAR, ROTFWT, and ROTRZT.

How to Order: Product Code 20. Specify nipple profile type, seal bore size, material, and Bean orifice size in 64ths of an inch.

E. Circulating Blanking Plugs for Nipples (Product Code 20)

Circulating Blanking Plugs hold pressure from below while allowing circulation from above, and can be held open to bypass fluid freely while running or pulling the plug. An internal valve is depressed during run-in and pull-out to allow fluid bypass, reducing hydraulic drag on the tool string. Types available include ROTCX, ROTCR, ROTFSB, ROTFWB, ROTRZB, ROTFGB, ROTFMB, and ROTRKB, covering the full range of BF, BR, and related nipple profiles in the Rebco completion system.

How to Order: Product Code 20. Specify the nipple profile type, seal bore size, and required material.

F. Pump-Through Plugs (Product Code 21)

Pump-Through Plugs hold pressure from below while allowing fluid to be pumped downward through the plug assembly from above, without requiring the plug to be pulled. This allows the operator to displace fluids below the plug, stimulate a zone, or perform injection operations without first removing the plug with a wireline trip. Types available include RXO, RXN, XRO, and XRN, selected based on the nipple profile and seal bore size.

How to Order: Product Code 21. Specify the nipple profile, seal bore size, and required material.

G. Plug Chokes for Tubing (Product Code 20)

Plug Chokes for Tubing are designed to withstand limited pressure differentials while allowing circulation from above in wells where no Landing Nipples are present, and set directly in the tubing bore. They are the tubing-set equivalent of the nipple-set circulating choke family, and the types available include ROTCW, ROTDW, ROTDD, and ROTCD, each suited to specific tubing sizes and pressure-holding requirements.

How to Order: Product Code 20. Specify tubing size, type (ROTCW, ROTDW, ROTDD, or ROTCD), seal bore size, and material required.
