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.

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.

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.

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.

We manufacture pup joints in all sizes, grades, and thread profiles to meet any requirement. Our tubing pup joints are manufactured out of seamless tubing and machined or upset to final dimensions. All API casing and tubing pup joints are manufactured according to API Spec 5CT. Special requirements are available on request.
