The coating adheres to the pipe and forms a protective barrier against corrosion and chemical damage. Spray lining is relatively quick and cost-effective, making it a popular choice for smaller diameter pipes. 2. Cured-in-place pipe lining (CIPP): CIPP involves inserting a flexible liner into the steel pipe and then curing it in place using steam or hot water. This method creates a seamless and durable lining that restores the structural integrity of the pipe. CIPP is commonly used for larger diameter pipes and can be installed without the need for excavation. 3. Slip lining: Slip lining involves inserting a slightly smaller diameter pipe into the existing steel pipe. The annular space between the two pipes is then grouted or filled with a cementitious material. This method is effective in rehabilitating pipes with minor defects or damages and can significantly increase the pipe's lifespan. 4. Fold-and-form lining: In this method, a flexible liner is inserted into the steel pipe and then expanded to the pipe's diameter using a mechanical or hydraulic process. The liner is then folded and formed to fit the contours of the pipe before being cured in place. Fold-and-form lining is ideal for pipes with irregular shapes or bends. 5. Coating lining: Coating lining involves applying a protective coating to the interior surface of the steel pipe. The coating can be sprayed, brushed, or rolled onto the pipe's surface and provides a barrier against corrosion and chemical damage. This method is commonly used for large diameter pipes or pipes in harsh environments. Each of these methods has its own advantages and disadvantages, and the choice of the lining method will depend on factors such as pipe diameter, condition, budget, and project requirements. It is important to consult with a professional pipe lining contractor to determine the most suitable method for a specific steel pipe rehabilitation project.
