Improving the Durability of Streak and Thermal Insulation of Petroleum Pipes by Using Polymeric Based Paint System

Abstract

This research deals with increasing the hardening and insulating the petroleum pipes against the conditions and erosion of different environments. So, basic material of epoxy has been mixed with Ceramic Nano Zirconia reinforcement material 35 nm with the percentages (0,1,2,3,4,5) %, whereas the paint basis of broken petroleum pipes was used to paint on it, then it was cut into dimensions (2 cm. × 2 cm.) and 0.3cm high. After the paint and percentages are completed, the samples were immersed into the paint. Then, the micro-hardness was checked according to Vickers method and thermal inspection of paint, which contained (Thermal conduction, thermal flux and Thermal diffusivity), the density of the painted samples was calculated,. The results of the research indicate that the concentration (5%ZrO2) gives the best results that the hardness of this concentration reached to (92 Hv). By contrast, the thermal conduction was continued at a insulation limit (2.4 W/m.K). The thermal diffusivity was (1.16 mm2/sec.), the thermal flux reached to (70.4 w.s 1/2/m2.K) and the density at the same percentage was (4.87 g/m3). This means that there is a linear proportionality and development with increasing in the percentage of Nano Zirconia additive to epoxy.

The Effect of Nanostructured Zirconia Reinforcement on the Mechanical and Structural Properties of a Copper-Based System

“…Moreover, the required loads are installed at the top of the device. The wear rate was calculated using the weighing method, which includes calculating the amount of weight loss for each sample by weighing the sample before attaching it to the device, completing the operation of the device with a digital sensitive balance and applying the following relationship [16,17].…”

The Effect of Adding Nickel Content to Turbine Blades Coating Using Thermal Flame Spraying

“…A porosity test was performed using the samples of coating layer after removing it from the surface during the examination. Archimedes , principle of immersion was used to calculate the proportion of pores in accordance with standard specifications (ASTM-C830) (Darwish et al 2020). Hence, the sample was weighed as dry (W 1 ) using an electrical balance of (±0.0001 gram).…”
