Abstract Fire protection of steel structures is playing an increasingly important role nowadays. The fire can be solved with intumescent paint, mortar, coating and concrete coating. Several tests have been performed to check these solutions. Combined structures, which consist insulation material panels, used increase the resistance structures. In this article, application combined solutions (co...

offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. a safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. while the cost...

Oil-impregnated paper is widely used in power transmission equipment as a reliable insulation. However, copper sulphide deposition on oil-paper insulation can lead to insulation failures in power transformers. This paper presents the influences of copper sulfur corrosion and copper sulphide deposition on copper wires and oil-paper insulation in power transformers. Thermal aging tests of paper-w...

Moisture inside the footwear can considerably affect the thermal insulation. In this study with a thermal foot model there was simulated three sweat rates (3, 5 and 10 g/h). Five types of footwear with various insulation levels (dry insulation from 0.19 to 0.50 m2 · K/W) were tested. The footwear insulation reduction was calculated for 1.5 hour period. The reduction in insulation was related to...

The consequences of zinc oxide (ZnO), Aluminum oxide ( 3 2O Al ) and Titanium oxide (TiO2) on tree growth have been comprehensively investigated in this paper. Zinc oxide (ZnO), II-VI compound semiconductor, is used in varistors in power insulation life. Due to its excellent electrical properties such as nonlinearity of current-voltage (I-V) characteristics, high fast-transient response and hig...

The article deals with the production of polystyrene concrete from recycled crushed in a rotary crusher waste foam packaging. resulting can be attributed to thermal insulation, used for insulation load-bearing structures buildings, as well structural and bearing layer outer walls low-rise buildings. dependence conductivity sample on density strength has been established, resistance shock loads ...

Advanced insulation materials are needed to support future electrodynamic tether missions as well as for other high voltage applications requiring direct exposure to vacuum/space plasma conditions, such as cabling to solar arrays. Some of the desired characteristics of these materials include the ability to resist damage from low-Earth-orbit environments (including atomic oxygen and micrometeor...

There are two critical parameters for microbolometers: the temperature coefficient of resistance (TCR) of the sensing material, and the thermal conductance of the insulation structure. Cytochrome c protein, having a high TCR, is a good candidate for infrared detection. We can use SU-8 photoresist for the thermal insulation structure, given its low thermal conductance. In this study, we designed...

The first standards based on thermal manikin measurements were developed in the1980s. In the Nordic countries tests for thermal insulation measurements of sleepingbags and cold protective clothing were developed. Similar standards were publishedin Germany by DIN and in the US by ASTM. At a European level, EN 342describes test methods and requirements for cold protective clothing...
