Respected sir,
I calculate the thickness of vessel, it comes less than 1mm , following are the parameters, p= 13 kg/cm2, OD=6 in,length=15.76in , joint efficiency = 1,allowable stress for API 2H GR 50 MATERIAL = 20015psi,
t= P*R/SE-0.6P.
calculated thickness arise so much less whats the problem??
kindly suggest.
