Inserted hoses or “hose linings” are linings that may be used to eliminate leakage in deteriorated pressure pipes. Typically, woven hose liners are flat fiber reinforced polyethylene hoses 150 to 500 mm in diameter. The hose is pulled into a host pipe and, once installed, the hose is inflated to conform to the walls of the pipe. Special fittings are used on the ends to secure the lining to the pipe. After installation, the flow is contained within the inner hose and can no longer leak through defects in the host pipe. The inner hose typically would be designed to resist the full interior pressure applied but could potentially be designed to rely partly on the structural support of the host pipe in resisting interior pressure (with the hose lining providing leak prevention). Hose linings are typically not designed to be able to resist external ground or groundwater pressures over the long-term and the host pipe is expected to continue to serve this function. Hose linings may laid loosely within the host pipe or be adhered to the host pipe during installation. In either case, consideration must be given to the situation when the pipe is depressurized temporarily – for maintenance or due to some unforeseen circumstance. If laid loose, the hose liner should be able to reinflate and displace any water accumulated within the annular space. If adhered, the adhesion should be considered sufficient to allow the liner to withstand the temporary depressurization.
