When a gas pipeline is constructed it is divided up into segments using block valve stations.This enables various sections to be isolated for inspection and maintenance.The block valve is typically a full-bore,soft seated ball valve to allow for pigging,a practice that includes cleaning and inspecting the pipeline. results for this questionHow are mainline valves operated?How are mainline valves operated?All mainline valves such as block valves are either operated by actuator,manually or remotely.The manual valve sites are physically closed by pipeline operators at the valve site location; hence manual valves are installed in urban areas where the access to valve and pipeline is adequate.Pipeline Basics,Construction and Associated Valves results for this questionWhat is a pipeline valve?What is a pipeline valve?Most valves in the gas pipeline system are designed to open and close automatically,especially during an emergency.Actuators are used to control these valves,usually on the largest shut-off valves that are difficult to be operated by hand.What is a Valve Station? - Definition from Trenchlesspedia

Block Valve - an overview ScienceDirect Topics

Block Valves Block valves are,as their name suggests,valves that are used to totally stop the flow of liquid or gas through a pipe.They are generally either open or closed and should not be used to control the flow of fluid.They can be either manually operated or,in the case of large valves,opened with a motorized assist.Block valves on PSV dischargeNov 27,2011Automatic block valveJul 22,2009Balancing ValvesMar 08,2009Block Valves Under PSV's?Oct 29,2007See more resultsDesign,Construction and Operation of GaspipelinesApr 10,2014·Valve station Structure .Valve station - Operation .Valve station - Construction .Venting system in order to be able to work without gas on single line sections .DVGW Code of Practice G 463 DN 1000 Distance service valve every 10 to 18 km .3) Design .Design,Construction an Operation of Gas PipelinesEssen 10.04.2014Chapter 5 Project Descriptionstation for the BTC pipeline and a border custody metering and gas offtake facility for the SCP pipeline.The expansion will comprise the construction of a new SCPX compressor station (CSG1),additional custody metering and gas offtake facilities x A new block valve station will be constructed in Georgia at approximately 28km

Pipeline Introduction all about pipelines

Introduction.Transportation of liquids by pipelines has been used for thousands of years.The first major exploitation and commercialization using pipelines started 150 years ago,and the building of long distance,large diameter pipelines was pioneered in the 1940s (Hopkins,2007).Todays pipeline industry has originated from the oil Pipeline Leak Detection - an overview ScienceDirect TopicsPipeline block valves shall be located and spaced along the mainline as necessary for safe operation and pipeline maintenance purposes.These block valves or isolation valves are needed in case of a natural disaster,such as a landslide or an earthquake,which could break the pipeline,or for third party damage to the pipeline caused by road Pipeline Planning and Construction Field Manual10.5 Pipeline Design and Valve Selection 211 10.6 Mainline Valve Locations 212 10.7 Valve Station Design 212 10.8 Buried Valve Vaults 214 10.9 Direct Burial of Valves 216 10.10 Natural Gas Pipeline Valves 216 10.11 Valve Placement on Gas Pipelines 217 10.12 Block Valve Spacing on Gas Transmission Lines 217 10.13 Valve Maintenance for Liquid and

block valve spacing on natural gas transmission pipelines is not related to public safety.Valves are useful for maintenance and line modification but they do not control or affect public safety as the injuries and fatalities on gas transmission pipelines generally occur during the first 30 seconds after gas has been released from a pipeline.Protocol Stations - BeaconMedaesProtocol Stations 11 - Gas Cylinder Installation Each flexible hose inlet connection (aka CGA fitting) has been installed to correspond to a given gas service.Insert the CGA fitting to the gas cylinder valve threaded part (which could be female or male depending on the gas service).First tighten by hand the CGA fitting to the cylinder valve.REVIEW OF SAFETY CONSIDERATIONS FOR NATURALBlock valves in pipelines have been used since pipelines were first constructed.They have been required in pipeline codes,such as ASME B31.1.(predecessor to ASME B31.8 Committee8 ),since 1952.The quantity and spacing of sectionalizing block valves has a significant impact on the construction cost of

Components of A Compressor StationPermitting and Regulatory FrameworkSafety ConsiderationsCommunity and Landowner ConsiderationsMunicipal and Zoning ConsiderationsRight of Condemnation Or Eminent DomainExtension's RoleResourcesNatural gas enters a compressor station through station yard piping and is passed through scrubbers and filters to extract any liquids and remove solids or other particulate matter that may be in the gas stream (Figure 1).Once the natural gas stream has been cleaned,it is directed through additional yard piping to individual compressors.Computers regulate the flow and number of units that are needed to handle the scheduled system flow requirements.Most compressor units operate in parallelSee more on extension.psu.eduSCADA AND TELEMETRY IN GAS TRANSMISSION SYSTEMSregulation,heaters,valves,odorant control are provided by the RTU or flow computer.Some stations have HMIs although it is more common for the operator to interface to the RTU via laptop.Block Valve Stations This is the simplest station on the pipeline.A small RTU is installed to monitor pressure (oftentimes flow andValve Solutions for Pipelines - SchlumbergerAlong a natural gas pipeline,you will find compressor stations that are used to compress the gas to a specified pressure,allowing it to continue to travel along the pipeline.The gas enters the compressor station with low pressure and velocity through an inlet valve,which can be a trunnion mounted ball valve like our T31 fully welded ball valve.What is a Valve Station? - Definition from TrenchlesspediaSep 30,2017·Valve stations are part of a piping system that controls the flow and pressure of the contents it carries.It acts as a control system and is built along the pipeline above the right-of-way such as near roads,away from overhead electric lines and other obstructions.Valve stations are placed in such a way that workers can get quick access in case of an emergency.
