Engineering plumbing drawing for an overhead tank detail, Sector-P, including design notes and construction requirements. It specifies all dimensions in millimeters, details the provision of puddle flanges during civil tank execution, and requires MS/ GI pipe flanged or threaded puddle flanges to be hot-dip galvanized and painted with two coats of anti-corrosive paint over primer before placing in RCC. It also states tack-welding to RCC retaining wall reinforcement and sets proper positions and levels for pipe sleeves and G.I. pipe connections.
