What Are the Production Steps for Casing and Tubing Pup Joints? Producing high-quality casing and tubing pup joints requires a series of precise and controlled manufacturing steps. These components play a crucial role in oil and gas operations, ensuring reliable connections and performance under extreme conditions. Below is an overview of the key production stages involved in creating these essential parts. Upsetting Upset forging is one of the first critical steps in the production of pup joints. It involves increasing the cross-sectional area at each end of a plain-end blank to create a stronger, more durable connection point. At our facility, we have introduced automation into this process through an advanced handling table. This innovation not only enhances safety during the upsetting process but also ensures consistent and accurate results across all pup joints. The automated system allows us to handle different lengths efficiently, maintaining the highest level of quality control throughout production. Hydro Testing After upsetting, each pup joint undergoes a hydrostatic test to check for leaks or structural weaknesses. This non-destructive testing method uses water pressure and a pressure recorder to detect any potential issues. Our modern hydro testing equipment is highly adaptable, capable of accommodating various lengths and pressure requirements as specified by API standards and individual customer needs. This step is vital in ensuring that every pup joint meets the necessary integrity and performance criteria before moving on to the next stage. Full Body Ultrasonic Inspection We use a custom-built, fully automated Full Body Ultrasonic Inspection system to examine our tubing pup joints. As a pioneer in the industry, we were among the first to implement this technology specifically for pup joints. This inspection method thoroughly checks both the internal and external surfaces for longitudinal and transverse defects. Unlike other non-destructive tests, ultrasonic testing offers superior accuracy due to its high penetration power, allowing it to detect even the smallest flaws deep within the material. Its high sensitivity ensures that no hidden defect goes unnoticed, guaranteeing that our customers receive the highest quality products available. Profiling For certain applications, we manufacture pup joints from heavy-wall mechanical tubing using a precision CNC profiling process. This method allows us to achieve tight dimensional tolerances and excellent surface finishes. The high-precision machining ensures that each pup joint meets exact specifications, making them suitable for demanding environments where reliability is essential. Special End Area Inspection To further ensure quality, we perform a wet magnetic particle inspection on the special end areas of the pup joints. This non-destructive test is effective in identifying surface and near-surface defects, including longitudinal and transverse cracks. By applying magnetic particles and observing their pattern under a magnetic field, we can quickly and accurately detect any irregularities, ensuring the structural integrity of the final product. Heat Treatment Each pup joint is heat-treated individually on a specially designed line. This process improves the mechanical properties of the material, enhancing strength and durability. Our heat treatment system is highly flexible, allowing adjustments for different lengths and configurations. This adaptability enables us to respond quickly to customer demands while maintaining consistent quality. After heat treatment, all pup joints are re-straightened to ensure they meet the highest standards of straightness and performance. By combining advanced technology with meticulous quality control, we deliver casing and tubing pup joints that meet the most rigorous industry standards. Every step of the production process is carefully monitored to ensure reliability, performance, and customer satisfaction.
