Compared to the host pipeline, when slip-lining or pipe bursting, what diameter HDPE pipe should be specified?
In slip-lining applications, the OD of the HDPE pipe is limited to between 85%t o 95% of the inside diameter of the existing host pipe, depending upon many factors including deflection, sag, bends, etc. PE pipes reduced resistance to flow often fully compensates for the slight reduction in diameter. For pipe bursting application as general rule of thumb is that the host pipe can be upsized two pipe sizes, for example 8 inch can be upsized to 12 inch, 12 inch to 18 inch, etc.
