Investigation of Reliability of PE Plastic Gas Pipe Joined With Butt Fuzzy Method

Energy has both vital and strategically important features. it is known that 26% of the energy consumed worldwide consists of natural gas. since it is used so commonly, there are lots of parameters related to the junction process of polyethylene based pipes and fitting members used in natural gas transfer. there is no doubt that inappropriate choices of these parameters will cause substantial damages of no return. in this study, natural gas pipes (pe 80 and pe 100) are joined by hot butt-welding and some tests are performed in accordance with the parameters and conditions determined by standards. in light of data collected, it is analyzed if hot butt-welding has the necessary characteristics to meet the standards for plastic pipe junction. the researches revealed that hot butt-welding method is a valid method for plastic pipe junction, and cheaper than other methods used. also, during the experimental studies, changes in welding quality are observed depending on the pipe density.
