Integrity assessment of ammonia storage tank by non-destructive testing
(Institut za ispitivanje materijala, Beograd, 2021)
Ammonia is a very dangerous fluid, and it is so important that its storage tanks are safe. Fusion welded joints (in further text: welded joints) are the 'weakest' location in some structures, in this case - tanks, and the ...
Influence of the polymer matrix type on cavitation resistance of composites
(Advanced Technologies & Materials, 2021)
Cavitation resistance of polymer matrix / basalt powder composites was determined in this work. Two types of composites
were tested: epoxy resin / basalt powder composite and polyester resin / basalt powder composite. In ...
Novel procedure to determine actual stress-strain curves
(Institut za ispitivanje materijala, Beograd, 2021)
This paper presents a novel procedure for determining the actual stress- strain curves for undermatching rectangular welded joints made of martensitic armoured steel Armox 500T. The method is based on an analytical expression ...
Corrosion effect on mechanical properties of aluminium alloys 2024-t351 and 7075-t651
(Institut za ispitivanje materijala, Beograd, 2021)
Results of static tensile testing of aluminium alloys 2024T351 and 7075-T651 are presented with different levels of corrosion exposure in the laboratory environment. Specimens from two different rolling directions are ...
Repair welding of pressure equipment with unacceptable defects
(Institut za ispitivanje materijala, Beograd, 2021)
The paper describes non-destructive testing and the repair welding technology for eliminating defects in the pressure equipment of RHE BB (Bajina Basta) (located in Serbia). The obtained results had justified the proposed ...
Cavitation resistance of basalt-based protective coatings and epoxy system
(Structural Integrity and Life, 2021)
The paper presents the results of synthesis and characterization of new refractory coatings based on basalt and epoxy system. Coatings are intended to protect the surfaces of parts of equipment and various structures in ...
