A pup joint is a short, non-standard length of pipe used to fine-tune the total length of a tubular string to meet precise requirements. These joints are essential in drilling and completion operations where exact measurements are critical for proper assembly and performance.
API casing and tubing pup joints are manufactured in accordance with API Spec 5CT, using high-quality, seamless oil country tubing that carries the official API monogram. This ensures reliability, durability, and compliance with industry standards.
In addition to standard options, premium pup joints are available with enhanced connections and can be produced in both API and exotic alloy grades, offering greater strength and resistance to harsh environments.
