Q: What are the different lining thickness options for ductile iron pipe?: The specific application and project requirements typically dictate the various options for lining thickness in ductile iron pipes. Cement mortar lining, polyurethane lining, and polyethylene lining are among the most commonly used options. Cement mortar lining, which is widely employed in ductile iron pipes, involves the application of a layer of cement mortar on the inner surface of the pipe. This lining provides corrosion protection and enhances the hydraulic performance of the pipe. The thickness of cement mortar lining can vary from 3mm to 6mm. Polyurethane lining, another popular choice, is particularly suitable for applications requiring resistance to abrasion and chemical attack. It is usually applied using a spray or casting method, and the thickness can vary depending on project specifications. Typically, polyurethane linings range from 1mm to 4mm in thickness. Polyethylene lining, a relatively newer technology, is commonly used in applications where chemical corrosion resistance is crucial. The lining is applied using a rotational lining process, wherein a layer of molten polyethylene is evenly distributed on the internal surface of the pipe. The thickness of polyethylene lining can range from 2mm to 8mm, depending on project requirements. It is worth noting that the lining thickness can be tailored to meet specific project needs, including the corrosiveness of the transported fluid, operating conditions, and desired service life of the pipe. Consulting with a qualified engineer or pipe manufacturer is advisable to determine the most suitable lining thickness for a given application.
