Engineering Quality

OFS offers sourcing and procurement solutions for high-quality oilfield tubing couplings designed for connecting individual lengths of production tubing in oil and gas wells. Tubing couplings are essential components of the production string, providing secure mechanical connections and supporting the integrity of tubular systems during drilling, completion and production operations. Our sourcing capabilities cover API Specification 5CT tubing couplings in various sizes, steel grades and connection configurations, including EUE (External Upset End) and NUE (Non-Upset End). Available material grades include J55, K55, N80, L80 and P110, subject to project requirements and manufacturer availability. Surface protection options such as phosphating and electro-zinc plating can also be specified according to operational requirements. These products are suitable for onshore and offshore oil and gas production applications where reliable tubular connections are essential. OFS supports customers through manufacturer coordination, technical specification review, quality documentation, procurement management and international logistics. Our sourcing approach focuses on matching coupling dimensions, thread configurations, material grades and applicable standards with customer requirements.
