Corrugated pipe is a material used in bridge construction projects, farmland drainage projects, etc. Qualified corrugated pipe has high strength, strong resistance, strong tightness and no leakage, and the material generally needs to be tested when entering the field.

Test Range
Metal bellows, plastic bellows, polyethylene double-wall bellows, single-wall bellows, polyethylene (PE) spiral bellows, metal bellows for prestressed concrete, etc

Test item
Appearance, size, ring stiffness, local transverse load, flexibility, tensile property, longitudinal load, radial stiffness, impact resistance, ash, aging resistance, leakage resistance, oxidation induction time, drawing force, sealing, etc
