Sample Problem – Insulation thickness calculation for a pipe

Calculate insulation thickness (minimum value) required for a pipe carrying steam at 180 0 C. The pipe size is 8" and the maximum allowable temperature of outer wall of insulation is 50 0 C. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0.04 W/m·K.

Oct 31, 2012· Our boiler tubes are 0.157" thick (Nominal thickness per drawing and it match the reading taken)! (Material is SA192 and at 900F you have S=5900psi per sec II) I was aware that when calculating you have to use design conditions but it might be possible that furnace can operate at a different temperature and will reduce thickness.

TM-6 Basic Principles of Tube Expandi


TM-6 Basic Principles of Tube Expanding

Feb 10, 2004· In general, only a 4% to 10% reduction in wall thickness is necessary to produce a tight tube in a serrated hole. On the other hand, reduction in excess of 15% may cause leaking, splits or flaked tubes. Carbon Steel is used in almost every type of pressure vessel built today. Tube wall reduction should be approximately 7% to 8%.
