Flexible and collapsible plastic corrugated tubing is commonly found on medical equipment such as ventilators, respirators as well as devices for anesthesia and sleep apnea.

Commonly used materials for medical applications include polyethylene (PE) and polypropylene (PP). Medical tubing can be produced in a variety of configurations, including:

• Corrugated or smooth inner wall

• Tapered profile

• Expandable/collapsible

QET’s high speed corrugators are capable of producing medical corrugated tubing with cuffs designed to our customer’s specifications for compatibility with the required connectors and fittings.

corrugated pipe machine
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.
