PVA extruded pipe ovality exceeds standard
Fenómeno do problema
PVA extruded pipe ovality >1.05, exceeding the 1.02 standard requirement
Análise das causas
Uneven pipe cooling, single-side cooling; unreasonable sizing sleeve design; uneven haul-off clamping force causes pipe compression deformation
Solução
1) Adopt annular spray cooling to ensure uniform temperature reduction; 2) Optimize sizing sleeve inner diameter and taper design; 3) Multi-caterpillar uniform clamping haul-off; 4) Increase vacuum sizing section length to ensure full sizing
Conclusão principal
Ovality is caused by uneven cooling and clamping; annular cooling and uniform haul-off are the key
