Desarrollo de procedimiento para roscado e inspección de rosca de tubería de producción, revestimiento y línea para la Industria Petrolera.

Abstract

The present study exposes the development of procedures to the threaded and inspection of threads of production, coating and line pipes to the oil industry developed at Missionpetroleum S.A. Company with the purpose of reducing the threaded subcontracting and threads connection inspection to tubing, casing and line pipe and get the API 5CT certification. The method used in this study is the concurrent engineering in the integrated development of products and processes which consists in the following steps: specification requiriments,setting up the process, calculation, process definition and procedure development and implementation, of the latter it gets the following results: Quality as a result of the proper selection of the process selection of the process and it is guaranteed by the nature of facilities, the variety plus the API 5CT certification to offer the threaded and inspection in the threads elements from wellhead, threads of production pipes, coating, manufacture of connectors and accessories with API threads elements. The root diameter af an API thread is essential parameter in the manufacturing, it is the base of cone for the machining of the strand, allow to conserve the step parameters, height, outline, conicity, stand off according to the API 5B. The table development to the threads API 5B and the procedures manual allow the standardization achieving the efficiency and effectiveness of the process. This is recommended to carry out the cost-benefit analysis of the implementation process and the development of procedures of threaded and API 5B/ 5CT threads control.
