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.

Stewart Tubular Products will manufacture Pup Joints to any length – inch or metric. Typical lengths are 2’, 4’, 6’, 8’ and 10’. Either API or proprietary threaded connections may be provided. Pup Joints manufactured by Stewart Tubular Products are available in all API and proprietary grades of steel, stainless steel and CRA steel.

Please send us your inquiry with detail item description or with Model number. If there is no packing demand we take it as our regular exported standard packing. We will offer you an order form for filling. We will recommend you the most suitable model according to information you offered.

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.

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.

Upset forging is a process by which a plain end blank is upset at each end to increase the cross section area. We have innovated upsetting by automating our handling table. This automated handling table not only helps us upset at different lengths safely, but also helps us to get pup joints to the highest degree of consistency and accuracy.

The hydro tests all of its pup joints. This non-destructive test uses water pressure and a pressure recorder to determine possible leaks. Our modernized tester can be adjusted to accommodate various lengths of pup joints, and test them at various pressures as required by API and customer specifications.

We has a custom & automated Full Body Ultrasonic Inspection system to inspect its tubing pup joints. We are the first in the industry to build and use a Full Body Ultrasonic Inspection for pup joints to ensure there are no defects on the external and internal surface longitudinal and transverse.

This inspection has greater accuracy than other non destructive tests, one reason is its high penetrating power to allow detection of defects deep in the pup joints. The Full Body UT also has high sensitivity which allows it to detect exceptionally small deficiencies. This inspection ensures that our customers receive the best quality pup joints on the market.

We also manufacture pup joints by profiling from heavy wall mechanical tubing. Profiling of pup joints are done in a high precision and tolerance CNC in order for us to achieve a high level of dimensional tolerances and surface finish.

The wet magnetic particle test is a non-destructive test that detects surface and shallow subsurface defects. Pup joints are inspected for longitudinal and transverse defects using this inspection method.

We have exclusively designed a line which heat treats each pup joint individually. This setup is versatile and dynamic, as it can be adjusted for various lengths of pup joints and modified accordingly. This gives us the advantage of catering to the needs of our customers extremely quickly. All pup joints are re-straightened after heat treat to ensure the highest quality.

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.

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 joint is designed and manufactured to adjust height of tubing or casing strings or depth of down-hole tools, and these pup joints are made of seamless steel pipes, and material for pup joint can be available in J55, K55, N80, L80 or P110. Pup joint can be available with tubing pup joint or casing pup joint, sizes of tubing pup joint range from 2⅜ inch to 4½ inch , and casing pup joint range from 4½ inch to 13⅜ inch , thread of pup joint can be 8RD, 10RD or BTC, length of tubingpup joint are often offered in 2ft, 3ft, 4ft, 6ft, 8ft, 10ft and 12ft, length for special purpose can be available as per order. Pup joints are machined with interchangeable Pin & Box thread on two ends or other configuration, one end is equipped with coupling, and another end is protected with closed end thread protector. Nominal weight of tubing pup joint is the same as tubing, and casing pup joint is the same as casing.

OCTG Pup Joints is one kind of common accessories for connection with casing and tubing. Threaded pup joints are divided into male threaded ends, single male threaded and Female threaded. The size and material is the same as the casing or tubing.
