Valves defined by construction

Description

Through the establishment of the present framework agreement the contracting authority wants to purchase ball, plug and gate valves for distribution and transmission of gas in the Danish gas grid. The framework agreement is divided into 4 lots: — lot 1: framework agreement concerning ball valves, — lot 2: framework agreement concerning plug valves, — lot 3: framework agreement concerning gate valves, — lot 4: framework agreement concerning specially constructed high pressure ball valves. The tender involves a joint procurement including the parties mentioned in section I.1). As an option the tendered frame agreement may also be entered by new entities within the Energinet group, cf. section II.2.11). The contracting entity wishes to procure valves, which are to be used as part of onshore metering/regulator stations, compressor stations and tie in with buried onshore gas pipelines. Outdoor underground valves to be buried at a depth of minimum 1 meter to top of pipeline as an integral part of line valve stations and by-pass for line valve stations. Design lifetime is 30 years.

Outdoor underground valves to be buried at a depth of minimum 1 meter to top of pipeline as an integral part of linevalve stations, by-pass for linevalve stations and compressor stations. Design lifetime is 30 years. Ball valves are durable, reliable and performing well after many cycles and closing securely even when they are rarely operated. In this case the desired ball valves are to be used as a part of a high pressure onshore pipeline which shall be commissioned and inspected by use of scrapers hence the valves will have to be full bore with an ID equal to the ID of the pipeline to allow for passage of these scrapers. Outdoor underground ball valves to be buried at a depth of minimum 1 m to top of pipeline and be of fully welded design. All valves shall be designed and manufactured to a design lifetime of 30 years.
