What Are the Production Steps for Casing and Tubing Pup Joints? Casing and tubing pup joints are essential components in oil and gas drilling operations. They serve as connectors between different sections of pipe, ensuring a secure and leak-free connection. The production process involves several precise and high-quality steps to ensure that each pup joint meets the strictest industry standards. Upsetting The first step in the production process is upsetting. This technique involves forging the ends of a plain end blank to increase their cross-sectional area. We have introduced automation into our handling system, which allows us to perform this process safely and consistently. Our automated handling table ensures that each pup joint is upset with precision, resulting in uniformity and accuracy across all products. Hydro Testing After upsetting, every pup joint undergoes hydro testing. This non-destructive test uses water pressure to detect any potential leaks. Our advanced hydro testing equipment is fully adjustable, allowing us to test various lengths and pressures according to API standards and customer specifications. This step ensures that each pup joint is safe and reliable for use in demanding environments. Full Body Ultrasonic Inspection We have developed a custom and fully automated Full Body Ultrasonic Inspection system to check the integrity of our tubing pup joints. As pioneers in the industry, we were the first to implement this technology for pup joints. This inspection method detects both internal and external defects, including longitudinal and transverse cracks, ensuring no hidden flaws go unnoticed. The ultrasonic test offers superior accuracy compared to other non-destructive methods. It has excellent penetration power, allowing it to identify deep-seated flaws, and high sensitivity to detect even the smallest imperfections. This rigorous testing guarantees that our customers receive only the highest quality pup joints available in the market. Profiling In addition to upset forging, we also produce pup joints through profiling from heavy-wall mechanical tubing. This process is carried out on a high-precision CNC machine, ensuring tight dimensional tolerances and an exceptional surface finish. This method is ideal for applications where exact measurements and smooth surfaces are critical. Special End Area Inspection To further enhance quality control, we conduct a wet magnetic particle inspection on the special end areas of the pup joints. This non-destructive test is effective in detecting surface and near-surface defects, such as longitudinal and transverse cracks. This step ensures that all critical areas of the pup joint are free from imperfections. Heat Treatment Each pup joint is heat-treated individually on a specially designed line. This setup is flexible and can be adjusted to accommodate different lengths and requirements. This flexibility allows us to quickly respond to customer needs and deliver high-quality products efficiently. After heat treatment, all pup joints are re-straightened to maintain their structural integrity and ensure the highest level of quality before final delivery.
