Prestressed plastic bellows is a single-wall bellows extruded by a plastic extruder by high-density polyethylene (HDPE) for post-tensioned prestressed concrete structures as a perforated pipe with prestressed ribs.
It is an ideal alternative to the original metal bellows in bridge and building construction.
Plastic bellows are divided into two categories: round pipes and flat pipes, which are connected in actual use by various types of plastic connectors.
The raw material for prestressed plastic bellows is HDPE. Its corrosion resistance is far better than that of metals, not afraid of acid and alkali corrosion, it does not corrode itself, and can effectively protect the prestressed ribs from corrosion.
