pup joint or upper nipple extensiom brands

A pup joint is Casing, Pipe or Tubing shorter in length than a standard tubular string. This allows for the adjustment and installation of tools and various tubular components when placement downhole is critical for a specific project. A Spacer Pipe is another reference used to identify pup joints. Pup joint features consist of connections, lengths, weights and material grade.

Crossover pup joints are manufactured from seamless mechanical tube. As with all Crossover products, each piece is marked with a distinctive job number and heat number that is fully traceable. A complete range of sizes (1" to 4.5"), weights (standard or heavy wall), and grades (J-55, N-80, L-80, and P-110) are commonly available from stock in 2", 3", 4", 6", 10", and 12" lengths. Lengths up to 20" are available upon request.

Manufactured according to API Spec 5CT using prime API monogrammed, seamless oil country tubing. Optional diameters, lengths, weights, and grades are available upon request.

Seamless pup joints with premium connections are available in API and exotic alloy grades. Premium ends are threaded by the manufacturer or authorized licensee.

Available with standard or special perforation spacings. Each joint has four rows of ⅜ inch holes drilled longitudinally along the tube. Optional patterns, hole size, and lengths furnished upon request.

Crossover, Inc. handles many types of API Couplings. As a rule, we stock enough of your common couplings which enable us to ship the same day if needed. We carry in stock J-55, L-80, N-80, and P-110. As for sizes, we carry 2 3/8”, 2 7/8” 3 ½”, 4 ½” tubing and some of the casing sizes up to 13 3/8”. Stock connections are EU 8 Rd., Nu 10 Rd., LTC, STC, and BTC. Our couplings are primarily of USA manufacture. If origin is not important, we can source other origins and sometimes beat the USA manufactured cost.

We manufacture a wide range of Crossover Couplings. Couplings are used to connect two sizes of pipes, or two different dissimilar threaded parts together. We offer special clearance couplings, special clearance couplings with bevels on both ends, and couplings with the API Seal Ring Modification.

Swages are generally Box x Pin with a transition on the outside diameter and the inside diameter of the swage to assure that there are no sharp corners to set up an area of stress risers. When stress risers occur, there is a chance that the part could fail due to the fact that the part would be prone to crack in these areas.

A blast joint is shorter in length than standard tubular joint. Built with a heavy wall pipe it is incorporated in the production string to facilitate production across any perforated interval and zone. Blast Joints are manufactured to the following specs connections, lengths, weights and material grade.

Crossover Blast Joints are heavy wall pin by box connectors used in tubing strings and are designed to minimize the effect of external erosive action caused by production fluids. Blast joints are located opposite the location of perforations in the production casing or just below the tubing hanger in sand frac designs. Crossover blast joints are manufactured from seamless mechanical tube in sizes ranging from 2 3/8” to 4 1/2” OD. Any length, grade of material, and threading is available at the customers request. Typical lengths are 10" and 20". Both API and Premium threads are available.

Crossover Flow Couplings are heavy wall box by box connectors used in tubing strings and are designed to minimize the effect of internal erosive action caused by production fluids. Flow couplings are located just above or below Landing Nipples, Safety Valves or Control Devices where turbulent flow problems are likely to occur. Crossover flow couplings are manufactured from seamless mechanical tube in sizes ranging from 2 3/8” to 4 1/2” OD. Any length, grade of material, and threading is available at the customers request. Typical lengths are 3" and 6". Both API and Premium threads are available.

Crossover Coarse Thread Tubing Safety Joint provides for emergency recovery of the major portion of the tubing string should it become necessary to abandon the equipment below. Precision left-hand threads facilitate the release of the joint by right-hand tubing rotation. Equipment requiring right-hand rotation should not be used below the Safety joint.

Crossover Straight-Pull/Shear-Out Safety Joint is used between packers in dual and triple completions and in selective completions using Hydrostatic Single-String Packers. It is also used when rotational releasing is not desired. When ran above the upper packer in a single-string completion, however, the shear value should be adjusted to compensate for any hydraulic conditions that exist when the string is landed, or that are created by well treating operations. They are available in keyed and non-keyed configurations.

Crossover Gas Anchor is an effective and simple design. It will increase oil and gas production, improve efficiency of the lift system, correct artificial lift problems caused by incomplete pump fillage due to gas interference and reduce operating cost.

Crossover can build these in any of the regular API Grades such as J-55, L-80, or P-110. These are usually only made going up or down one size in either direction such as ¾” to 1” or 1 ½” to 2”.

A saver sub falls under the drill string accessory tool category and a short pipe that is replaceable and expendable without a major investment. This accessory protects the Kelly or topdrive component threads and those components represent a significant capital cost and considerable downtime when replaced. Saver sub are manufactured to the following specs connections, lengths, weights and material grade.

A lift sub falls under the drill string accessory tool category and utilized to mobilize various tools during drilling or fishing operations. Lift Sub are manufactured to the following specs connections, lengths, weights and material grade.

A circulating sub falls under the downhole accessory tool category that regulates flow rates, especially drilling in slimhole wells or wellbore cleanout projects. Circulating sub is manufactured to the following specs connections, lengths, weights and material grade.

Crossover Drop Ball Circulating Subs are manufactured from AISI 4140/4145. The standard is pin by box. They are activated by dropping a chrome steel ball, which lands on a sleeve and as pressure increases, the pins in the sleeve are sheared. This causes the sleeve to move down and expose four ports in the side of the sub diverting the fluid flow.

A side-entry sub falls under the drilling tool accessory category to allow various drilling, fishing, wireline operations through drill pipe without interference from the rig"s top drive unit. Circulating sub is manufactured to the following specs connections, lengths, weights and material grade.

The style shown is built from one piece of 4145M bar stock and the excess material milled away and then threaded. There are also Lift Caps which are Cast Steel Castings and are threaded with the correct thread, but the rest of the plug is casts to create the bail.

Some customers request Lift Caps with Pad Eye for lifting. These are also made out 4145M and can be manufactured to fit any of several shackles. They can be built with either the pin or the box facing down.

These brushes are generally run on Rotary Shoulder Drill String to Brush the inside of Casing Down Hole. These brushes will remove rust, scale and other contaminates that build up on the inside diameter (ID) of the casing. Usually run in preparation of running a packer or some other piece of equipment that needs a fairly uniform ID to set.

Crossover Inside BOP Valves are manufactured from AISI 4145. Crossover"s one piece design is much more robust than the traditional two piece construction design. Crossover"s one piece design typically allows for standard connection OD"s and shorter overall length parts. This eliminates the service break which allows for quicker disassembly.

A washover pipe is Casing or Pipe shorter in length than a standard tubular string. Made of large-diameter pipe with a cutting surface at the tip, washover pipe is run in the well and then the cutting edge grinds the fish to a smooth surface and continues normal operations. Washover Pipe is manufactured to the following specs connections, lengths, weights and material grade.

Crossover rotary shoes are manufactured from specially tempered steel to provide the ultimate in toughness and durability. They are used to cut a clearance between the fish and the wall of the well bore. Each shoe is tailored to fit a particular downhole need and normally is run on the bottom of one or more joints of washover pipe. Shoe design is dictated by whether it cuts on the bottom, on the OD, on the ID, or any combination of these. When hole sizes permit, additional clearances can be cut using side ribs, thus providing greater circulation.

Scott, W. S., and C. E. Hoffman. "An Update On Use of Coiled Tubing for Completion and Recompletion Strings." Paper presented at the SPE Eastern Regional Meeting, Charleston, West Virginia, October 1999. doi: https://doi.org/10.2118/57447-MS

Perforated Production Tubes are joints of tubing with machined holes along four lines 90o apart along the length of the tube. Perforated Production Tubes are usually installed between the bottom two nipples of a completion. With this tool, downhole recording devices, such as temperature and pressure gauges, can be installed in the lower nipple profile to acquire flowing pressure and temperature measurements. The upper nipple provides a point to plug the tubing below a packer. This facilitates packer setting or workover operations. The Perforated Production Tube, sometimes called a Ported or Perforated Pup Joint, allows for unrestricted flow of fluid or gas. The use of this tool enhances the accuracy and reliability of acquired downhole production data, which otherwise would be distorted due to flow restrictions. The Perforated Production Tube comes standard with 200% flow area of the production string it is connected to.
