The specialists of Start Engineering JSC have successfully finished a project, including design, delivery and installation of external hot water pipeline DN 450/500/800 PN16 for “Plovdiv – North” TPP.
The design comprises construction of the external pipelines in the section from the cogeneration station of EVN Bulgaria Toplofikacia and the main heat pipelines of the station to Plovdiv town. It is completed successfully in the end of 2012 by contract between Start Engineering JSC and Siemens. The value of the project is 860 000 EUR.
The activities, executed by the specialists of Start Engineering JSC are:
- Preparation of final design, in compliance with БДС EN13480-3 and БДС EN13480-6;
- Delivery of pre-insulated pipes and their corresponding fittings;
- Installation of pre-insulated pipes with diameters DN50, DN100, DN450, DN500 and DN800;
- Installation of deaerators DN50 and drainages DN100;
- Horizontal drillings Ф 1220 mm below railway line;
- Fabrication of reinforced concrete shafts and immobile supports;
- Installation of PE splices DN630, DN670 and DN1000 and their filling and sealing;
100% of the welding works are subjected to radiographic control.
The pipeline was executed with high quality basic materials of the German company ISOPLUS, featuring high technical level, corresponding to the Bulgarian and international standards. All welding works are executed, according to the requirements of BDS EN 13480-5. One hundred percent of them were subjected to radiographic testing, which proved their quality. Successful hydraulic high pressure tests were made to the pipeline. Start Engineering JSC has proven competence in the execution of complex projects, is what they declare from Siemens. Our company has proven competence in the organization and execution of complex projects and also the required financial security and know-how in the execution of complete engineering projects, without the necessity of using subcontractors.
Start Engineering JSC successfully implements the actually operating quality assurance system, according to ISO 9001:2008, to which a quality assurance system of the welding processes is also integrated, according to БДС EN 3834-2, is what they add from Siemens.
Start Engineering JSC is also participating in the construction of a major part of the electrical installation of the cogenerating plant. The basic activities include laying the cables, construction of the separate kinds of connections and assistance of the basic teams during commissioning of the facilities.
