HDPE being an inert material, it is unaffected by most
chemicals, be it acidic or alkaline. More than 3 decades old
pipes in service are available without much damage to the
piping system to prove the point.
The advantage of using a single raw material without any
additives for manufacturing the pipes with a monolithic
joints made with fusion of the pipe materials have enabled
vacuum sewerage system possible. This has reduced the
burial depth as well as the diameter of the pipes used as
compared to conventional gravity sewerage system leading
to reduction of system cost enormously along with saving
of time and CO2 emissions.
The installation or rehabilitation of a sewer system main
can be significantly faster and easier with HDPE pipe. This
is primarily due to the pipe’s lighter weight, ease of handling,
and its suitability for trenchless technologies like Pipe
Bursting or Horizontal Directional Drilling. Because of its
flexibility, HDPE pipe can be shaped during its installation
to curve around obstructions and angles without difficulty.
Its light weight allows you to pull long assembled lengths
of the pipe through long difficult tunnels under roads and
structures with little effort at greatly reduced costs. These
benefits and many others make it a serious contender as a
sewage piping solution.
