4. Each technical parameters and performances of pup joints conform to standards of API Spec 6A and can be exchanged with like products internationally.

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.

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.

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 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.

Crossover"s Drop-in Check Valve is a retrievable check valve. It is retrievable by means of a retrievable tool (gravel girdie) run in on wireline. When needed the check valve is pumped down the drill string to the landing sub. The dogs are locked in place with pressure from below the valve. The check valve will open to allow circulation and close when circulation is stopped.

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.

Integral Pup Joints are used for transporting high-pressure flow in fracturing, cementing, maintenance, and test manifolds. These are made from high-quality alloy steel, integrally constructed, forged-ended features seamless upset construction. Standard integral pup joints are available in different models, pressure, and temperature rating.

We manufacture pup joints in all sizes, grades, and thread profiles to meet any requirement. Our tubing pup joints are manufactured out of seamless tubing and machined or upset to final dimensions. All API casing and tubing pup joints are manufactured according to API Spec 5CT. Special requirements are available on request.

Integral → The pup joints are one-piece construction made from alloy steel and feature wing union end connections that eliminate welds and threads. The pup joints are capable of handling a variety of fluids and a working pressure of 15,000 psi. Available in lengths up to 15 feet, they are pressure rated to 10,000 psi for sour gas service.
