Glass Fibre extruded pipe ellipticity exceeds standard
Fenómeno do problema
Glass Fibre extruded pipe ellipticity >1.05, exceeding 1.02 standard requirement
Análise das causas
Pipe cooled unevenly, single-side cooling; sizing sleeve design unreasonable; haul-off clamping force uneven causing pipe compression deformation
Solução
1) Adopt annular spray cooling to ensure uniform cooling; 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
Ellipticity is caused by uneven cooling and clamping; annular cooling and uniform haul-off are key
