there are also a large number of different areas of application for corrugated pipes. we manufacture complete extrusion lines for production of corrugated pipes for application as below,
Protective pipes for flexible, pre-insulated district heating lines
Protective pipes for the installation of:
Floor water pipes
Cold and hot water pipes
Drinking water pipes
Oval ventilation pipes for controlled ventilation of the living space
Suction hoses for filter systems and swimming pool cleaning
Support pipes for winding tube application
Drain hoses for washing and dishwashers
Siphon pipes for sinks
Drinking straws |
two types of pipe corrugator:
Internal blow moulding
Vacuum forming
Blow Moulding:
This technology consist of blowing low pressure (0,1-1,5 bar) through the die head spider into the center of the continuously extruded hot plastic tube. The air is retained by a plug with metallic or silicone washers.
The hot plastic material is expanded by the internal air pressure against the corrugation machined in the mould blocks which chill and holds the tube against the moulds to provide the desired geometry. Corrugated products formed by internal air must have constant I.D. dimension.
Vacuum forming:
This technology consists of pulling the hot plastic tube against the mould blocks by vacuum suction applied through the moulds applied to the plastic tube outside diameter surface. Vacuum from the moulds keep the tube against the moulds to provide the desired geometry. Corrugated products formed by vacuum may have variable I.D. dimensions.
