Desarrollar un manual de procedimientos para la inspección de uniones de soldadura a tope y tipo T en tanques de almacenamiento fabricados de acero ASTM - A36

Abstract

The objective of this titling project is to develop a manual of procedures for the application of non-destructive tests such as: visual inspection, penetrating liquids and ultrasound phases arrangement, applied to tope and type T joints present in petroleum storage tanks, according to API Standard 650; developing specific procedures for each type of non-destructive test and its application in defection specimens. A comparative analysis that corroborates the validity of the inspection procedures applied, and those performed by a certified external entity, evaluated by means of acceptance and rejection criteria of API Standard 650, obtaining as a result a percentage of error below the 10% limit, corresponding to the human and environmental factor in the taking of measurements, in conclusion, the inspection procedures are applicable for welding cords of atmospheric storage tanks. These procedures are described in manuals developed for the different inspection techniques: visual, penetrant liquids and ultrasound phase arrangement. This manual is going to be a guide for the new procedure developing for entities which are specialized in the application of non-destructive testing, and which are looking for the certification of their inspection.
