AB  - The paper presents assess the integrity of welded joints on pressure vessels made from HSLA steel. Risk based approach is applied using Failure Analysis Diagram to assess likelihood of failure. Special attention is paid on cracks defects by advanced ultrasonic testing which are unacceptable by standards, but difficult to be repaired. Structural integrity assessment was performed based on evaluation of fracture mechanics parameters, which has been used to improve safety of welded structures, focusing on welded joints on pressure vessel, as the most critical components. Simple engineering method is presented, based on the Failure Analysis Diagram (FAD) to explain evaluation of fracture mechanics parameters and their critical values in order to assess structural integrity of welded joints.

AB  - Risk analysis of containers in a coal drying facility was performed using the Failure Modes and Effects Analysis (FMEA) method in combination with the risk matrix. The selected exploitation period analysed for all vessels was 5 years, since there is a lot of data about the maintenance performed during this period, including results of material testing performed by an accredited laboratory. Based on all issues detected by testing, risk probabilities (with corresponding levels of severity) of various defects were calculated, and potential expected repair costs determined. These probabilities were then used as input for the risk matrix which indicated the most critical types of defects, both in terms of occurring probability and the severity of their occurrence. It was concluded that through-thickness cracks were the most dangerous defect in this case. Furthermore, high probabilities of most defects considered, implied that containers will become unreliable and unfit for continued exploitation in the near future. Suggested means of preventing failures include a more thorough periodic maintenance and control of these vessels, until it is possible to fully replace them with new equipment.

AB  - The paper describes the reconstruction procedure of 3 autoclaves, i.e. equipment used for drying raw coal. Due to material degradation in working conditions and damage, the lower part of the autoclave, of steel Altherm 55 (commercially known) is completely replaced by 18 Mn Mo4-5+NT
(commercially known), in order to extend service life of this pressure equipment and increase plant reliability. The reconstruction procedure of autoclaves is presented, i.e., the welding technology for the lower (new) part of the autoclaves. Structural integrity assessment is performed by NDT methods and hydrotests on reconstructed equipment before recommissioning, as well as for the strict criterion of the quality requirement of welded joints exposed to dangerous working fluids.
