riser pup joint factory

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.

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 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 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.

“They got a riser wrench stuck on a bolt, and in the process of removing it, the wrench struck the guy, knocked him off of the spider (another part of the riser), and he fell over and was pronounced dead,” McCormick told the Houston chapter of the American Petroleum Institute at a January event about robots in the oil and gas industry.

The death helped Transocean decide to commission Houston company Offshore Robotics to build a robot riser system that can help take humans out of the most dangerous areas of a drill ship, known as the “red zone.” Now, the companies are getting ready to launch the third robotic riser system in the Gulf of Mexico. But while Transocean has signed on to the concept, experts said barriers such as cost and a hesitancy to adopt new technology could prevent the widespread use of robots in the oil field.

Cost was one of the questions asked back at the American Petroleum Institute Houston chapter’s event discussing robots in the industry. While the price varies, the robotic riser system can cost upwards of $2 million.

If companies can get past those challenges, robotic systems like the offshore riser can not only help improve safety, but can allow workers to step away from boring jobs with the potential for injury.  John Martin, the president of Offshore Robotics, said that’s what makes the riser successful: it eliminates the need for four people to haul and install those 55 pound bolts.

“It"s very tiresome on the people that are doing the task,” Martin said, but when they got the robotic riser system up he adds that, “the operators, the floor hands, they are seeing these robots doing the job that they used to do – and instead of being upset, they come and thank me.”
