mechanically anchored steel tanks Temporary Openings after Hydrostatic Test#0183;Web viewQ.8.6 TEMPORARY OPENINGS AFTER HYDROSTATIC TEST.When approved by the purchaser in writing,and only in the case of tanks which when complete have no shell penetrations,it is permitted to restore by welding up to four temporary shell openings after the hydrostatic test in accordance with the provisions of this section.[DOC]APPENDIX BRECOMMENDATIONS FOR DESIGN AND mechanically anchored steel tanks Temporary Openings after Hydrostatic Test#0183;Web view1 Oil-sand layers under steel tank bottoms inhibit cathodic protection current. B.10.1 When a tank is required to be mechanically anchored,see API 650 5.12.1 16 10/9/2008 material at the bottom junction does not extend above top of tank bottom extension to form a water trap outside of the tank shell.After tank hydro-testing inspect Water Handbook - Preboiler Industrial Boiler Corrosion Protection of steel in a boiler system depends on temperature,pH,and oxygen content.Generally,higher temperatures,high or low pH levels,and higher oxygen concentrations increase steel corrosion rates.Mechanical and operational factors,such as velocities,metal stresses,and severity of service can strongly influence corrosion rates.
