7. Select r2 such that the equivalent thickness of insulation of pipe equals to the insulation thickness estimated in step 6. From this value, calculate the radial thickness of pipe insulation = r2-r1 8. Adjust the desired surface temperature values so that the thickness of insulation is close to the standard value of 1" ( mm). 9. The Economic Thickness of Thermal InsulationDesign Note The conventional method of evaluating the performance of insulation is to measure the R- value, the conductive heat flow resistance of the material. The measurement of conductive heat flow resistance . Energy saving vs. insulation thickness according to nominal pipe sizes for plastic pipe. A. Das ß demir et al./ Applied Thermal Engineering () – for a mm pipe this value. The Economic Thickness of Insulation for Steam Process Distribution Pipelines Bassam Al-Zgoul Al-huson University College, Al-Balqa Applied University, P.O Alhuson , Jordan Abstract Steam pipes are very important in engineering application and are widely used. Thermal insulation .

Economic thickness is the thickness of insulation, which will result in minimum total cost of energy more detail is required, it is suggested that BS “Code of practice for thermal insulation of pipe work and equipment in the temperature range - °C to °C” be consulted. Optimum thickness for a pipe: The economic thickness of insulation depends on the first cost (insulating cost) and maintenance cost of insulation and annual value of heat loss, which depends on the cost of producing the steam and thermal conductivity of the lagging. Economic benefits: • Insulation reduces average home heating and cooling costs by around 30% • Insulation reduces the burden of increasing energy prices. • The cost of installing insulation already pays for itself in around years through reduced energy bills, . types of insulation systems that are indicated by the type code on the Piping and Instrumentation Diagrams (P&IDs), data sheets, and other design documents. This Practice provides guidance on insulation design criteria, insulation materials, extent of insulation, determination of insulation thickness, and insulation material properties.

In this study, the optimum insulation thickness of pipes used in district heating pipeline networks, energy savings over a lifetime of 10 years, and payback periods are calculated for the five.   A thermo-economic approach for determination of optimum thickness of thermal insulation applied to piping systems “ A simple correlation for estimation of economic thickness of thermal insulation for process piping and equipment,” Appl.

This handbook of thermal insulation design economics is a manual presenting both the theory for determining the economic thickness of insulation and tables for determining the thickness based upon installation conditions. Included are thicknesses for flat surfaces, pipe fittings, and those for fluid and electric heat traced pipe and equipment.
