Abstract
SE DESCRIBE UN METODO PARA TENSAR GRANDES PASADORES (16) UTILIZADO EN CUBIERTAS DE SEGURIDAD (12) PARA ABERTURAS EN RECIPIENTES DE PRESION, ACOPLADORES DE TUBERIAS, VALVULAS Y SIMILARES, EN EL QUE SE UTILIZA UNA JUNTA DE SELLADO (18). SE DISEÑA UN METODO PARA PREVENIR EL GOTEO EN CONEXIONES DE JUNTA CONTROLANDO LA INTERACCION ENTRE LA TENSION DEL PASADOR Y LA COMPRESION DE LA JUNTA. EL METODO ESTA RELACIONADO ESPECIALMENTE CON LA DETERMINACION DE LA TENSION DEL PASADOR A LA QUE SE CONSIGUE LA COMPRESION COMPLETA DE LA JUNTA. ESTO PERMITE AL USUARIO VERIFICAR LA DENSIDAD DE JUNTA CORRECTA, EL ASIENTO DE JUNTA CORRECTO Y LA CARGA PREVIA DEL PASADOR. EL METODO LLEVA CONSIGO CAMBIOS DE MEDICION EN UNA DIMENSION (E) RELACIONADA CON LA COMPRESION DE LA JUNTA SEGUN AUMENTA LA TENSION DEL PASADOR (F). LA COMPRESION TOTAL DE LA JUNTA PARA DETENER UNA COMPRESION DEL METAL SE NOTA COMO UN CAMBIO BRUSCO EN LA PROPORCION DELTA E/DELTA F. SE DESCRIBE UN METODO SECUNDARIO PARA IDENTIFICAR EL PUNTO DE COMPRESION TOTAL DE LA JUNTA UTILIZANDO TRANSMISION ACUSTICA. EL METODO SECUNDARIO PUEDE UTILIZARSE PARA VERIFICAR LOS RESULTADOS DEL PRIMER METODOA METHOD FOR TENSIONING LARGE PINS (16) USED IN SAFETY COVERS (12) FOR OPENINGS IN PRESSURE CONTAINERS, PIPE COUPLERS, VALVES AND THE LIKE, IN WHICH A SEALING GASKET IS USED (18) IS DESCRIBED. A METHOD IS DESIGNED TO PREVENT LEAKAGE IN JOINT CONNECTIONS BY CONTROLLING THE INTERACTION BETWEEN PIN TENSION AND JOINT COMPRESSION. THE METHOD IS ESPECIALLY RELATED TO THE DETERMINATION OF THE PIN TENSION AT WHICH THE COMPLETE COMPRESSION OF THE BOARD IS OBTAINED. THIS ALLOWS THE USER TO VERIFY THE CORRECT GASKET DENSITY, THE CORRECT GASKET SEAT AND THE PRE-LOADING OF THE PIN. THE METHOD LEADS WITH MEASURING CHANGES IN A DIMENSION (E) RELATED TO THE COMPRESSION OF THE BOARD AS THE PIN TENSION INCREASES (F). THE BOARD'S TOTAL COMPRESSION TO STOP A METAL COMPRESSION IS NOTED AS A SHARP CHANGE IN THE DELTA E / DELTA F RATIO. A SECONDARY METHOD OF THE BOARD'S TOTAL COMPRESSION IS DESCRIBED USING ACOUSTIC TRANSMISSION. THE SECONDARY METHOD CAN BE USED TO VERIFY THE RESULTS OF THE FIRST METHOD
