Abstract

Se provee una unión roscada en la cual la cara periférica externa 31 de la punta del pasador 3 presenta una forma cónica simple, la cara de cierre 21 de la caja 1 presenta una forma curva convexa hacia fuera, y un punto de cierre xₚ definido por la siguiente ecuación es superior o igual a 0,2 pulgadas donde p es una presión de contacto, x es una distancia desde un extremo del pasador en la dirección del eje de la tubería, y x₁ y x₂ son, respectivamente, un límite inferior y un límite superior de un dominio de x correspondiente a la parte de cierre.A threaded joint is provided in which the outer peripheral face 31 of the tip of the pin 3 has a simple conical shape, the closing face 21 of the case 1 has a convex outward curved shape, and a closing point xₚ defined by The following equation is greater than or equal to 0.2 inches where p is a contact pressure, x is a distance from one end of the pin in the direction of the pipe axis, and x₁ and x₂ are, respectively, a lower limit and an upper limit of a domain of x corresponding to the closing part.
