FORMULA PARA CALCULAR EL ESPESOR "t" MINIMO EN TUBERIAS t = ( P x D ) / ( 2 ( Se + Py ) DONDE:

P = PRESIÓN D = DIAMETRO EXTERIOR Se = ESFUERZO MAXIMO PERMISIBLE 20,000 LBS/PULG² (PARA TUBOS CON COSTURA) Se = ESFUERZO MAXIMO PERMISIBLE 17,000 LBS/PULG² (PARA TUBOS SIN COSTURA) y = FACTOR DE TEMPERATURA 0.4

FORMULA PARA CALCULAR EL ESPESOR "t" MINIMO PARA INSTALAR UNA TAPA EN TUBERIA

t=d

0.25P / S

DONDE:

P = PRESION MAXIMA DE OPERACIÓN EN PSI d = DIAMETRO INTERIOR DE LA TUBERIA S = ESFUERZO PERMISIBLE 18,300 LBS/PULG² t = ESPESOR DE LA PLACA

FORMULA PARA CALCULAR EL ESPESOR "t" MINIMO PARA INSTALAR UN COMAL

t=d

3 . P / 16 Y

DONDE:

P = PRESION MAXIMA DE OPERACIÓN EN PSI d = DIAMETRO INTERIOR DE LA TUBERIA Y = ESFUERZO DE CEDENCIA 30,000 LBS/PULG²

FORMULA PARA CALCULAR EL ESPESOR "t" MINIMO PARA INSTALAR UNA BRIDA CIEGA

t=D

0.5 P / S

DONDE:

D = DIAMETRO EXTERIOR S = ESFUERZO PERMISIBLE 18,300 LBS/PULG²

NOTA:

C = FACTOR DE CORROSIÓN 0.125" Ó 1/8"

TUBERIAS

TAPA EN TUBERIA

UN COMAL

A BRIDA CIEGA
