PRODUCT OVERVIEW
Connection Transition Components for project-specific requirements.
Connection transition components join tubulars or equipment with different sizes, thread systems, bores or functional interfaces. Both mating sides must be defined completely; a generic crossover description does not establish connection compatibility or load capacity.
The product basis includes upper and lower interface data, OD, ID, overall length, material, heat treatment, pressure and mechanical loads, service environment and any proprietary connection authorization. API 5B and API 7-2 references are used only for their applicable thread families.
OAK coordinates interface reconciliation, controlled machining data, material traceability, connection inspection, NDT and protected delivery.
