CORROSION DEGRADATION OF STEEL PIPES IN INDIRECT COOLING CIRCUIT OF GAS CLEANING Mária Hagarová1,a*, Jana Cervová2,b, Marek Vojtko3,c 1,2,3Department of Materials Science, Faculty of Metallurgy, Technical University of Košice, Slovakia amaria.hagarova@tuke.sk, bjana.cervova@tuke.sk, cmarek.vojtko@tuke.sk Keywords: steel pipe, corrosion, cooling circuit, crack Abstract: The paper deals with corrosion damage of steel pipes which were a part of the indirect cooling circuit of gas cleaning.
Methods of analysis of corrosion degradation of pipes The methods of analysis of steel pipe specimens included standard procedures commonly used for evaluation of corrosion attack on metal materials.
Additional analysis was carried out on material sampled from the pipe at the site shown in Fig. 1.

The shape, size and type of material of the fibers play an important role for distribution and orientation of fibers.
All these findings could have serious affect on the theoretical presumption that the fibers are distributed in all directions and therefore these types of materials should not be assumed as isotropic (especially UHPFRC).

These standards do not seem to apply in tropical climate where wall thick nesses are comparatively smaller (between 100 and 230 mm), and are usually of less dense materials.
Types and Sources of Data The study relied on two types of data, namely: i) Primary data physically obtained from the model buildings (comfort factors); ii) secondary data such as thermal comfort indices, insulating properties of materials, etc, obtained from design manuals, charts, standards, etc.
This goes to confirm the widely held view that materials with low heat capacity minimize heat storage in building envelop.

Introduction The main existent techniques for repair and strengthen reinforced concrete (RC) beam-column joints can be grouped as follows: repair with epoxy (injection of epoxy resin in the cracks of lightly degraded elements); removal and replacement of concrete in more damaged areas; jacketing with RC layers, masonry blocks or steel plates; use of composite materials.
The main characteristics of these materials can be found elsewhere [2].
