Manufacture and delivery of a Convective Steam Superheater for Steam Generator No. 7 – according to technical specification and design documentation
About This Opportunity
TranslatedThis tender concerns the manufacturing and delivery of a convective steam superheater for Steam Generator No. 7, based on a provided technical specification and design documentation. The project involves the fabrication of the superheater, which is structurally composed of three coil blocks. Specifically, the "Convective Steam Superheater" (drawing TK329.17.00.00.00) requires the production of two identical "Convective Steam Superheater 1" blocks (drawing TK329.17.01.00.00), each containing 26 coils. Each of these coils is detailed in drawings TK329.17.01.01.00, further broken down into "Coil 1" (TK329.17.01.01.01) and "Coil 2" (TK329.17.01.01.02). Additionally, one "Convective Steam Superheater 2" block (drawing TK329.17.02.00.00) with 27 coils is to be manufactured. Its coils are shown in drawing TK329.17.02.01.00, comprising "Coil 3" (TK329.17.02.01.01) and "Coil 4" (TK329.17.02.01.02). All pipes used must be of steel grade 14MoV6-3 EN 10216:2014. The tender specifies several modifications to the original design drawings. These include adjustments to the straight sections and bends of coils 1, 2, 3, and 4, primarily involving an increase in the straight section length and changes to the lengths of specific bends or knee sections. The overall objective is to produce a high-quality, custom-fabricated steam superheater that meets the detailed technical requirements and design modifications outlined in the tender documents.
This is a supplies contract in the energy and power and trade and industry sectors, with a focus on Power Generation and Industrial Machinery. Located in Bulgaria, Europe, this opportunity is open to firms and consortiums, with an estimated budget of BGN 500,000.
