Steam cure lining uses pressurised steam to heat the resin in an inflated CIPP liner, producing a controlled and rapid cure typically in 60 to 120 minutes. The lower water volume compared with hot water cure reduces handling and discharge requirements on the works site. Steam cure is suitable for diameters from 100mm to 600mm and is often used by contractors working on Thames Water adopted sewers under planned rehabilitation programmes. The steam generator must be sized to maintain the temperature profile required by the resin manufacturer and works should follow BS EN ISO 11296-4. Operators must be trained in confined space and pressurised equipment safety, and the workzone should be isolated to protect site personnel from steam release.
