Fiberglass reinforced plastics (FRP) equipment is fabricated by applying layers to build up the required thickness. Peel is a phenomenon peculiar to FRP equipment since the bonded layers could be peeled back at relatively low loads. This paper will cover peel definitions, peel test methods, and peel strengths.
Presents guidelines for cathodic protection of reinforcing steel in concrete structures. The guidelines are limited to impressed current cathodic protection systems for new or existing atmospherically exposed reinforced concrete and are not intended for application to prestressed concrete. Criteria described include 100 mV polarization development/decay, statistical distribution analysis, and E-log I analysis.
This standard practice provides format, content, and other guidelines for developing a materials selection diagram (MSD). An MSD documents the materials selection of new equipment and piping for the refinery, process chemical, power, and other industries. Information is also provided on key issues that arise when materials are selected.
