Development of PE
50 Years PE pipesfor gas and water supply
• flexibility (pipes in variable lengths)
• resistance against corrosion
• safety, less damages cases
• easy laying (welding)
gas supply:
•PE transport pipelines for gas are normally used until DN 200
•Some big cities until DN 350e.g. London (England) up to DN 600
today DN 600 or even larger
-water supply:
PE up to DN 200 is more economicalthan cast iron (in the opinion some major
water companies)
