When selecting a supplier/producer for your penstock project, it is important to understand the quality requirements and some important variables in order to choose a high- or low quality penstock producer. The most important criteria's and requirements for selecting a high- or low quality penstock producer are the following:
- DIN-EN-ISO-3834: Make sure that your penstock producer is always certified according the DIN-EN-ISO-3834! The ISO-3834 is the standard European Quality Requirement for fusion welding of metallic materials as penstocks. Only producers with ISO-3834 can give you the full Quality Assurance that all welding equipment is periodically calibrated en fully suitable for the job. Also, it will give you the full Quality Assurance that the penstocks are welded only by Welders which are fully certified according "Welder Approval Test Certificate in Accordance with ISO-9606-1 (2017)". CTV Armaturen & Penstocks GmbH is fully certified according to the DIN-EN-ISO-3834.
- DIN-EN-1090-1: The EN 1090 standards are European standards that regulate the fabrication and assembly of steel and aluminium structures and are recognized by the EU-Construction Products Regulation (CPR). It assures Factory Production Control in Compliance with EN 1090 in accordance with CPR. CPR requires all metal producing and processing companies wanting to sell construction products in the European Union to certify their factory production control (FPC). Manufacturers of hot-rolled steel products or aluminum components, for example, need FPC in compliance with the harmonized specification EN 1090-1.All construction products meant for the European market must be CPR compliant with the main focus primarily on written “Declaration of Performance” and modified CE marking. For high quality penstocks, please always ask your penstock producer to issue a EN-1090 Manufacturer Certitication. CTV Armaturen & Penstocks GmbH is fully certified according to the DIN-EN-1090-1 in Execution Class 3.
- CE-Marking for Penstocks: Penstocks are outside the scope of the Pressure Equipment Directive (European Directive 97/23/ce -PED), therefor only penstock producers which are certified according DIN-EN-1090 are able to issue a CE-Marking on the penstocks.
- Alternatively, you might want to specify the origin of the Stainless Steel used for the productiuon of the penstocks: Is the Stainless Steel of European Origin or Chinese Origin?
Penstocks are designed to cut off the flow of sewage / water in municipal and industrial sewage treatment plants, in water melioration systems, in road and highway drainage systems and in other applications like fish farms. Usually, Penstocks aremounted in prepared channel recesses or by means of fixing pins in the channel clearance. Channel and wall penstocks are usually manufactured according to individual customer orders due to their sizes.
