Althon offer a range of HDPE penstocks designed for use in manhole chambers and Flow Control chambers.
Our Flow Control penstocks are suitable for use with pipework up to 300mm and have a design life of 50 years at 1Mwc and 72 hours at 5Mwc
Typically the contractor will create a flat surface within the manhole chamber to fix the penstock to. The smoother the surface finish of the concrete the better the seal will be between the penstock and the wall. We provide all required fixing bolts, chemical anchors and an EPDM seal with every penstock.
Our penstocks for Flow Control and manhole chambers are manually operated with a T – key and have a non – rising spindle. Where required we can provide a spindle extension from the top of the penstock to the cover level.
If you require a penstock for pipework greater than 300mm Please view our full range of HDPE Penstocks.
