pup joint manufacturer lsaw steel pipes factory

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.

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.

Tubing pup joints are desiged and manufactured as per API 5CT to be used be adjust height of tubings, and tubing pup joints are made of seamless steel tubings. Material grade of tubing pup joint can be avalialbe in J55, K55, N80, L80 or P110, sizes of tubing pup joint range from 2⅜¡± to 4½¡±, thread of pup joint can be 8RD, 10RD or BTC, and end connection types can be NUE and EUE. length of tubing pup joint are often offered in 2ft, 3ft, 4ft, 6ft, 8ft, 10ft and 12ft, length of pup joint for special purpose can be available as per order. Tubing 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. Tubing pup joints are internally and externally hydrostatic tested with tension and compression loads, and torque tested, electromagnetically inspected, pup joint is full-body drift and straightness visual inspected, and phosphated and dye-penetrant inspected. and finally painted by machine to ensure excellenct appearance. Finished tubing pup joints are often packed by steel belts in bundles, and then fixed in steel rack for easy transportation.

Casing pup joints are desiged and manufactured as per API 5CT to be used be adjust height of casings, and casing pup joints are made of seamless steel casings. Material grade of casing pup joint can be avalialbe in J55, K55, N80, L80 or P110, sizes of casing pup joint range from 4½¡± to 13⅜¡±, thread of pup joint can be 8RD, 10RD or BTC, length of tubing pup joint are often offered in 2ft, 3ft, 4ft, 6ft, 8ft, 10ft and 12ft, length of pup joint for special purpose can be available as per order. Casing 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.

Finished casing pup joints are often packed by steel belts in bundles, and then fixed in steel rack for easy transportation.

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.

Carbon steel pipe mainly refers to the carbon mass fraction is less than 2.11% without containing deliberately added alloying elements of steel, with the level of carbon contained in a steel being one of the most important factors to be influence on its the strength of the steel, the hardness increases, and reduces ductility, toughness and weld ability. Besides, it generally also contain a small amount of silicon, manganese, sulfur, phosphorus in addition to carbon. Compared to other types of...

Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium—the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing
