HDPE Pipeline Lining History
Generation 1: Slip Lining
A pressure bearing pipe is installed into the host pipe, utilizing the host pipe for no other purpose than as a conduit. This system limits through put and potentially pressure capabilities. A custom sized HDPE pressure bearing liner can be designed to take advantage of most the available annular space.
Generation 3: HDPE Thin Wall Compressed Fit Liners
The compressed fit liner technology has been used since the early 1990’s successfully in various systems. The liner is designed so that the fit liner is designed with an outside diameter is larger that the internal dimension of the host pipe. At the time of installation, the HDPE liner is compressed percentage points smaller than the in
The compressed fit liner technology has been used since the early 1990’s successfully in various systems. The liner is designed so that the fit liner is designed with an outside diameter is larger that the internal dimension of the host pipe. At the time of installation, the HDPE liner is compressed percentage points smaller than the internal host pipe dimension. Once installed the liner expands back out and forms a compressive fit within the host pipe.
Generation 2: Expanded Fit HDPE Liner
Generation 2: Expanded Fit HDPE Liner
The expanded fit technology has been used since the 1980’s successfully in various systems. The expanded fit liner is designed with an outside diameter percentage points smaller the internal dimension of the host pipe and uses the system pressure to expand the liner into the wall of the host pipe for the pressure bearing surface. l.
