This standard describes the requirements for materials, equipment, certification, and procedures for the field application of spray-in-place polymeric (SIPP) linings to the interior of existing potable water pipelines. The water pipelines to be renewed may be constructed of pipe materials such as steel, ductile iron, cast iron, asbestos cement, and concrete. Related work required for performing a complete contract is also generally described.
The standard covers all polymeric materials used in spray-in-place applications including epoxies, polyurethanes, polyureas, and hybrids of these compounds.
This standard can be referenced in documents for the purchase of SIPP lining of pipelines for water supply service. The requirements of this standard apply when this document has been referenced and then only to SIPP lining of potable water pipelines.
