Prestressed plastic corrugated pipes Features:
Can effectively prevent the chlorine ion invasion
Insulation, prevent the electric current corrosion
higher linear expansion coefficient (140*10-5)
low modulus of elasticity (800Mpa)
High strength, Can bear strict pressing , uneasy to be damaged
Corrosion resistance, ensure the post-tensioned pre-stressing concrete structure durability
Good resistance to fatigue, can greatly improve the component anti-fatigue capability
Good resistance to sealing. Permeability higher than metal corrugated pipe, more used in vacuum grouting, can greatly improve the component anti-fatigue capability
Reserve passageways friction coefficient is less than metal wave grain tube, reduce tension friction loss
