Best Management Practice

Therefore, the designer must be aware of the potential for liner collapse and consider options for the liner design that include the effect of service conditions on the physical state of the liner. [...] This step allows a visual inspection of the short section of liner at the exit location and helps to determine the presence and effect on the liner of damaging anomalies. [...] Note that the shortened length of the liner section at bends does however need to be sufficiently long to enable the liner to be stretched out at the flange for installation of the flange stub end adaptor. [...] To help prevent the liner sealing off the vent under pressure, usually for high pressure gas gathering pipeline applications, a stainless-steel screen mesh is applied to the liner just below the vent hole to provide separation of the liner and vent hole. [...] The application of heat is usually by use of heated water and is applied to help reduce the liner stiffness and ease the yielding of the liner.
