2.1.2.Welded Penstocks With the advancement in welding technique and development of higher heads,all welded steel penstocks are mostly used.The pipes are formed by butt welding the longitudinal and circumferential joints.The main advantage of this type over riveted penstocks are (i) Lower Weight (ii) Lesser Hydraulic Losses and (iii) Ease of Fabrication and Erection.Large-Diameter Cooling Water Pipe and Penstocks Selecting PlanningInspecting The Existing Lining and Gathering Information For The SpecificationPreparing The SpecificationThe Bidding ProcessIn-Process Technical Support and QA InspectionSummaryAbout The AuthorPlanning for penstock relining work must begin months or years before the actual project start date.Major items to consider at the beginning of the project include gaining an understanding of the condition of the existing lining system,if present,and the condition of the piping itself.This is determined by performing inspections of the penstock interior.The outcome of these assessments will then be used to prepare a concise,detailed project specification.When informative specifications are developed for a relining projSee more on ktaSteel PipeA Guide for Design and InstallationThe fabricators of fusion-welded seam pipe followed similar initial production sequences as for lockbar; first rolling two long half sections,then using electric-fusion welding,joining the two long pipe-halves into a single section.Inflatable Pipe Plugs Product Selection GuideWarning All pipe plugs must be blocked or anchored adequately against a force equal to the head pressure times the cross-sectional area of the pipe.Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs.NEVER use an inflatable plug when its failure could cause injury or catastrophic damage or as the only means of protection for personnel working downstream.
