Bead and Crevice Free (BCF) Fusion Machines

The BCF fusion machines made by GF Piping Systems stand up to the highest requirements in terms of quality and purity for fusion joints. The machines are ideal for high-purity applications in the pharmaceutics, biotech, foodstuffs, process and microelectronics industries.

The fusion joining process consists in transmitting precisely defined thermal energy to the pipe and fitting ends being joined by means of half-shell heating elements. At the same time an elastic, pressurised bladder supports the inside surface of the fusion zone in order to prevent the formation of an internal fusion bead.  Fully automatic process control of the fusion joining process with a fusion joining machine developed in-house by GF Piping Systems permits very simple handling and reproducible fusion quality.  The machine covers the PVDF (SYGEF) and PP-n (PROGEF Natural) material in the dimension range of d20 mm up to d110 mm.
