Strands & Ducts
Tpt systems offer engineers a complete range of anchorage and prestressing forces to meet the most arduous requirements, whilst at the same time they are designed to give trouble-free simple site operation. The table below gives the standards of the strands which may be used with our T rang systems.
The recommended duct diameters of corrugated metal sheaths, having a minimum thickness of 0.3mm, are indicated for each anchorage. However, these should be checked against the local requirements and regulations.
The High-Density Polyethylene (HDPE) or Polypropylene corrugated ducts enhance corrosion protection and insulation. The duct provides excellent secondary corrosion protection in aggressive environments. Tpt systems can be connected with the plastic ducts conveniently with our plastic Deviation Cones.
