Pipe system involves various components, including perforated pup joints and are made from different materials. We offer wholesale perforated pup joints to create a smooth channel for the pipe systems in both commercial and residential areas.

In the oil and gas drilling industry, the tubing pup joint is a critical component for the completion of a well. The pup joint allows the driller to change out the drill pipe without having to pull out the entire string of pipe from the well. This is a common practice, especially when drilling deep wells. Because of this, the tubing pup joint is one of the most important joints in any well.

Tubing pup joints are small-diameter tubing that is used in conjunction with casing to complete a well. The pup joint is run in the hole and cemented to the casing, and then the production tubing is run over it and attached. This arrangement allows for the use of smaller-diameter production tubing, which results in less pressure drop and improved production. The pup joint is usually located in the last few feet of the tubing string.

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.

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.

3. It has low cost, can be threaded between each other and repaired easily. The tubing pup joint is an accessory generally used in industrial pipelines. Tubing pup joints can be made of flat style and external upset, of various specifications, and under API specifications. Tubing pup joint is a length of the short pipeline, same as pipelines except for the length. It has various lengths such as 0.25m, 0.5m, 1m, 1.5m, 2m, 2.5m, 3m, 3.5m, etc. A perforated pup joint is used to assemble running string. The casing is the same. Tubing pup joints, same as pipelines, can be divided into NUE and EUE, with or without coupling, male buckle plus male buckle or male buckle plus female buckle, and other forms.

In order to avoid damage to the oil casing, attention should be paid to the support of the Wholesale LTC Casing Coupling For sale during the design and manufacturing process, and the joint position of the oil casing should be paid attention to during the installation process.

The number of strings of casing used for a well depends upon how deep the well is. In some cases, the well may only have two strings of casing to reach from the bottom of the reservoir to the surface; the surface pipe and the final string of casing (also known as the long string or oil string). However, in deeper wells the final string may require more tensile strength or the lower joints may be created with extra support in the event of a collapse. In the event the lower joints are heavier than the rest of the joints on the long string, a similar joint is installed at the top (referred to as the gauge joint). The gauge joint provides the crew with a reference, letting the crew know that any tool going through the first joint will be able to go through all of them.

In order to perforate the casing, it is essential for the crew to know what the bottom hole pressure is inside the pipe, as well as to anticipate the inside pressure of the formation. If the pressure is miscalculated and is greater in the formation than what is inside of the casing; the instant the perforations are created through the pipe, the fluids will rush into the casing (forced by the bottom hole pressure) and blow the perforated gun up the hole. It will go up the hole at such a tremendous speed that it will wad up the electrical line and create numerous problems.

Since the tubing has to reach a specific depth within the well, and be placed without being cut or threaded; tubing is usually available in a wide range or random lengths, typically ranging from 28-32 feet (with shorter lengths referred to as pup-joints).  Pup joints (see Figure 1) are added to the top of the tubing string, and are used for final spacing (also, click here if you’d like to know more about Tubing String basics, Perforation Placement, Measuring Pipe Diameter, Running and Pulling a Tubing String, and basic troubleshooting of the Tubing String!)

The mud anchor is a full joint of tubing placed at the bottom of the string that may be cut off to a certain length. It is generally between 16-24 feet, and used for:

In order for the oil and/or water to enter the tubing string located in the reservoir, it has to be perforated. While there are a number of ways to accomplish this task, the most common options include:

Installing a perforated pup joint over the mud anchor with a collar in between the two pieces. While the typical length is usually between 3 or 4 feet, perforated pup joints (see Figure 2) can be as small as 2 feet or as large as 12 feet. These holes in the tubing are around 1 inch in diameter and are placed a few inches apart on all sides. The purpose of these small holes is to prevent large objects from entering into the tube.

Using a short joint or leaving the bottom of the pipe open just below the seating nipple. (Typically very few operators will use this method. This is due to the risk of large objects entering the pump and causing it to stop functioning.)

Using a perforated mud anchor with an electric drill, or by cutting holes using an oxyacetylene torch. Generally these holes are 3-6 inches apart, and are placed no farther than 6 inches below the upset on each of the four sides (extending anywhere from 2-4 feet).
