We are the largest manufacturer of API pup joints in North America. All of our pup joints are manufactured from the highest quality API seamless tubing, and per API 5CT requirements. We have dedicated heat treat, NDT, and automated threading lines to provide you with best quality pup joints with quicker turnaround times.

PUP JOINTS are a joint of pipe of non-standard length used to adjust the length of tubular strings to exact requirement. We provide both tubing (2 3/8” to 4”) and casing (4” to 13 3/8”) in all lengths. With our myriad of licenses (quality page) we are able to cut to length, thread and couple to meet specified needs. API casing and tubing pup joints are manufactured according to API Spec 5CT using prime API monogrammed, seamless oil country tubing. Premium pup joints are also available with premium connections and in API or exotic alloy grades.

MARKER JOINTS are a joint of tubing used in a workover or completion tubing string that serves as a position or depth indicator. In most cases, a marker joint is significantly shorter than other joints in the string so that it is easily noticeable.

FLOAT EQUIPMENT, normally collars and shoes are housing of various sizes of casing supporting the cementing application in well construction. We manufacture to customer print all sizes and varieties of collars and shoes.

CROSSOVERS can be a critical element in well construction, completion and workover; to change size and thread connection for specific requirements without changing the entire well design. We manufacture crossovers of all sizes and with our thread licenses, matching and miss-matching connections to integrate most tools and accessories in the well. Refer to our quality page for specific applications and licenses.

Pup Joints are a mandatory part of equipment in almost any well. Due to their shorter length, they are typically easier to handle and to use. At the same time, they provide the same performance as the tubing/casing/drill pipe that they are attached to.

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.

The drill pipe joint is an important connecting part of the oil drill pipe and drilling tool, and is widely used in the oil drilling industry. Our pup joint drilling is finished with high-quality and unique materials for excellent durability and precise dimensional accuracy. The threads on the fittings are cut on a CNC machine, which ensures high precision of the threads and prolongs the service life of the fittings. Considering the specificity in practical applications, we use phosphate coating or copper plating to enhance the wear and chemical resistance of the joint. This pup joint drilling has good mechanical strength and comprehensive performance and meets international standards, it can be widely used in oil, natural gas, sewage treatment and other industries.

Outside Diameter of Tubing Joint: From 2-3/8"(60 3mm) to 4.5"(114.60mm) Pipe End: EUE/NUE Outside Diameter of Casing Joint: From 4-12"(114 3mm) to 20*(508mm)

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.

4. Acidification and fracturing: In the later stage of good drilling, to increase the production of oil and gas wells, it is necessary to input acidification and fracturing media or solidification into the oil and gas layer, and the medium and solidification are transported through the short tubing section.

Drilling Tools offers a variety of subs in both AISI 4145 heat-treated steel and non-magnetic metal. Virtually any type of sub can be manufactured in-house to customer specifications. Listed

UBHO and muleshoe subs are used in directional drilling BHA"s and are typically run directly below a non-mag drill collar. This sub contains a landing sleeve that can be oriented to the directional

Available in a variety of sizes, Drilling Tools" filter subs range from the retrievable and non-retrievable mud screens to the Diffuser™ blade technology sub assembly. See detailed information on

Pup joints are key components in special drilling operations when specific spacing considerations are required. Our pup joints can be ordered with an 18-degree taper or square shoulder and with pressed

Drilling Tools International offers cross-over subs and bit subs for any drill string connection size and function needed. Manufactured from alloy heat treated steel, our subs meet API

Magnetic positioning pup joints: A short casing used to accurately determine the depth of oil and gas layers when perforating. The casing is usually connected to the top 30m above the oil (gas) layer. No magnetic treatment.

Casing pup joint: A short casing that is smaller than the standard length casing. The top casing is connected to the last casing when it is used to adjust the position of the top surface of the casing string and connect the short casing to the cement head. (This is to adjust the length of the casing for drilling, to meet the depth of the casing to meet the cementing needs)

Magnetic positioning depth technology, using the composite perforation depth technology of natural gamma (GR) and magnetic positioning (CCL) oil jackets, to synthesize the single-well testing depth curve, integrated logging curve and casing short section curve assessment. Through calculation, using this technology can not only avoid the disadvantages of high error of single magnetic positioning depth, but also the accuracy of perforation depth can be increased to 99.98%.

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

A pup joint is a casing or tubing of length shorter than Range 1 with the same thread connection, used to adjust the length of tubular strings to its exact requirement.

Pup Joints are manufactured from AISI 4145H or 4140H-modified alloy, heat-treated to a Brinell Hardness range of 285-341 with a Charpy “V” notch minimum impact strength of 40 ft/lb at 70° F and one inch below the surface. Pup Joints are heat-treated to 110,000 PSI minimum yield. All connections are phosphate coated to impede galling during initial make-up.

Integral Pup Joints dedicated to Sour Service applications are available. PJ -110 PUP S are Sour Service Pup Joint using ASCOWELL C material providing improved resistance to Sulfide Stress Cracking with high yield strength.

ADFO manufactures Pup Joints with Integral Hammer Union end connections.These Pup Joints are used on high pressure discharge lines, choke and kill lines, auxiliary flow and other applications.
