casing pup joint factory

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.

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.

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.

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%.

Before the perforation and other measures, insert a magnetic probe. On the test curve, the casing collar can have a jump point on the curve, that is, the position of different casing collars can be found. Because the special casing is shorter, the two points of change that are close to each other are reflected in the depth of the short casing. Looking down from this point to find the required depth can reduce the error.

BLAZE is adequately equipped to supply NPST Pup joints made of high quality seamless pipeline with  male & female detachable hammer union. NPST has uniform bore for greater flow capacity. NPST pup joints are available in 2″ to 4″ sizes, length for pup joint range from 1 feet to 20 feet at 15000 psi. Pup joint with Non- pressure seal thread union (NPST) are especially engineered for high pressure, abrasive services where welded connections are not desired. The design provides a strong, permanent end connection without butt welding. An epoxy thread-locking compound secures the connection.

Casing or Tubing Pup Joints, Casing or Tubing Connectors and Casing or Tubing Couplings. In addition it is capable of Threading items at Groups 1, 2, 3 & 4 of API spec. 5CT. Items supplied by BLAZE meet the Quality Standards as defined in API 5CT assuring

BLAZE is also well equipped to supply Line Pipe Couplings/ NPST pup joints with wide range of specifications. In addition we can supply thread Line Pipes and its accessories of various sizes. Items meet the quality standards as laid down in API – 5L.

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.

Pup Joints are manufactured from AISI 4145H or 4140H-modified alloy, heat-treated to 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.

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.

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.
