Advantages:

High ring rigidity: Polypropylene bellows has high ring rigidity, which can withstand external pressure and reduce the risk of deformation and damage. 
Lightweight: Compared with traditional pipes, polypropylene bellows has a higher ring stiffness.
Lightweight: Compared with traditional pipes, polypropylene bellows is lightweight, making it easy to handle and install. 
Good corrosion resistance
Good corrosion resistance: Polypropylene materials are resistant to a wide range of chemicals, making them suitable for use in the chemical industry and sewage systems. 
Heat and ageing resistance
Heat and ageing resistance: able to withstand high temperatures for long periods of time and has good ageing resistance. 
Good insulation: Polypropylene materials are resistant to a wide range of chemicals.
Good insulating properties: Polypropylene bellows is a good insulating material, suitable for the protection of wires and cables. 
Good insulating properties
Convenient construction: Due to its light weight and flexibility, polypropylene corrugated pipe can be constructed quickly, which can shorten the project cycle. 
Easy to construct
Impact resistance: polypropylene corrugated pipe has good impact resistance, can be subjected to external impact to maintain intact. 
Impact Resistance
Flame retardant properties: Some types of corrugated polypropylene pipe have added flame retardants to slow down the spread of flames.
