Investigation of New Material for Deterging Heat Exchanger Tube

This work represents new material can be used in cleaning process of heat exchanger tubes. Rubber projectiles are back bone of on line cleaning mechanism but it has poor mechanical and thermal features. Three materials have different properties with micro scale powder solid phase (aluminum, aluminum oxide and copper) had been added to (LSR) with different volume ratios (2%, 5%, 10%, 15%). specimens had been prepared with certain method and under specific conditions. Compression test was applied to identify stiffness factor of these new composite materials. Wear test was applied to finite the wear rare coefficient for these materials. Un certainty statistics was applied for measurements results so It's founded that with increasing volume ratio each of stiffness factor and wear rate coefficient increase linearity up to (15%) for all specimens. copper filler give best for stiffness that stiffness factor reaches about (30 (N/(mm/mm))) at volume ratio 15%) but poorest wear resistance with wear rate coefficient (9*10-6) Mpa-1 inversely aluminum filler gives best results in wear resistance with wear rate coefficient (6*10-6) Mpa-1 but weakest in stiffness test with stiffness factor (28 N/(mm/mm) at volume ratio 15%). Aluminum oxide was the best choice for new projectile material as it combines between good stiffness and wear resistance.
