of HDPE pipe. The first use of polyethylene pipe in a nuclear safetyrelated application started with the selection of a high performance PE 4710 resin made by Dow Chemical to make pipe that could replace carbon steel pipe at the Callaway Nuclear Power Plant.HDPE Replaces Carbon Steel in Safety-Related Pipe SystemAmerenUE,a subsidiary of Ameren Corp.,has pioneered the use of polyethylene (PE) as a new alternative to steel pipe ESW systems at its 1,200-MW Callaway plant.Polyethylene material does not corrode,rust,rot,pit,tuberculate,or support biological growth.It also has an outstanding field performance record for more than half a century in wStarting from ScratchPlace The PipeAs this was to be the first ever use of HDPE in a safety-related water pipe system at a nuclear plant in North America,the team at Callaway had to create a material specification and related procedures from scratch.In the process,they underwent a change in mindset from focusing on what was available to specifying what was really needed.Most importantly,Callaway engineers began to work closely with members of the HDPE pipe value chain.These players included The Dow Chemical Co.(Dow) as theSee more on powermagEstimated Reading Time 10 minshdpe replaces carbon steel in safety - Janinamoda Boiler HDPE offers seismic resistance,in that it can safely accommodate repetitive pressure surges above its static pressure rating and is well suited for seismic loading due to its natural flexibility.HDPE Replaces Carbon Steel in Safety-Related Pipe System(plate) The world's first class 3 safety related nuclear PE4710 hdpe replaces carbon steel in Natural gas pipeline systems on site distribution 2019 The material of choice for most above ground installations of natural gas piping is ASTM A53/A53M,black steel,Schedule 40,Type E or S,Grade B.carbon steel pipe.Steel piping is used for systems operating in excess of 1,000 psig (6,900 kPa) and delivering natural gas to locations in excess of 300 miles from the last compressor station.
HDPE Replaces Carbon Steel in Safety-Related Pipe System.·The pH scale is logarithmic and commonly ranges from 0 to 14.It indicates how acidic or basic a solution is,with 0 being the most acidic and 14 being the most basic.A pH of 7 indicates neutrality.A pH range of 8 to 10.5 is commonly used for pipe systems that include steel.People also askHow is HDPE used in non-safety related pipe systems?How is HDPE used in non-safety related pipe systems?One immediate option was HDPE,which had already been used at Callaway in non-safety-related water pipe systems such as fire protection piping.The installation of this system gave Callaway engineers valuable experience with HDPE and pipe fusion methods.HDPE pipe was attractive to AmerenUE at Callaway for several reasons:HDPE Replaces Carbon Steel in Safety-Related Pipe SystemPipa HDPE menggantikan pipa steel - HDPE SPECIALISTHDPE Replaces Carbon Steel in Safety-Related Pipe System Jimmy Zhou and Frank Schaaf Corrosion of steel water pipes in the safety-related piping systems of aging U.S.nuclear power plants is fast becoming a safety concern and a significant operational cost,not to mention an indication of potential future liability for nuclear utilities currently constructing new plants or retrofitting existing sites.
