New ASTM International Standard Aids Pipeline Repair

ASTM International’s committee on plastic piping systems is developing a proposed standard that will provide procedures for rehabilitating or reconstructing pressure pipelines and conduits used for water, sewer, gas, and petroleum.

The proposed WK60068 standard describes the robotic application of a structurally independent spray-in-place pipe (SIPP) technology. Such application is useful for the rehabilitation of pressure pipelines constructed of steel, cement, cast iron and concrete and other related materials that can host spray-applied thermosetting linings. The linings have been certified by the material manufacturer, through third parties, for SIPP lining of pressure pipelines.

Currently, the only SIPP standard available to municipal and industrial engineers is for structurally interactive lining systems, where there needs to be cohesive strength with the host pipe for the lining to be effective, noted Kent Weissenberg, committee chair, and CEO and chief technology officer of SippTech.
