Implication

Experimental study demonstrates compliant butt fusion welding parameters for ethylene chlorotrifluoroethylene piping, indicating potential to replace failure-prone mechanical flange connections.

Key Points

To establish optimal on-site butt fusion welding parameters for ethylene chlorotrifluoroethylene piping to replace conventional mechanical flange assemblies.
Controlled hot plate temperature, fusion time, and welding pressure to accommodate the high melt viscosity and low surface activity of ethylene chlorotrifluoroethylene.
Evaluated structural integrity, chemical characteristics, and morphology of welded joints using tensile tests, FT-IR, SEM, density measurements, and automated visual scanning.
Welded joints produced using the optimized heating, timing, and pressure parameters fulfilled all structural requirements of the DVS 2201 code standards.
Implementation of the direct fusion protocol eliminates leak-prone flange connection points, significantly lowering material usage, fabrication demands, and installation time.
