About this file
This document is a technical specification and visual guide for renovation and replacement work on an industrial tank system and associated piping infrastructure. The project encompasses comprehensive demolition and installation tasks across multiple system components.
The scope of work includes: demolition and replacement of the complete drain pipe system using stainless steel (1.4401) with all associated valves, leverage mechanisms, and hand wheels; replacement of extraction lines (stainless steel 1.4001/1.4401) up to valve connections, including core drilling and sealing; installation of new overflow pipelines connected to the drain system (stainless steel 1.4401); installation of a new hydrostatic level/pressure measurement system per specifications in the Statement of Work; installation of a new flammable sampling valve; and replacement of the drain pipe with core drilling and sealing. Additional work includes demolition and closure of multiple wall penetrations, replacement of lighting with new LED fixtures, demolition and relocation of the ladder directly under the access point, demolition of old level indicators and filling lines with installation of new level indicators near the ladder, and fabrication of a stainless steel gutter to cover the drain (approximately 1.57m x 0.8m). The photographic documentation on pages 1-6 shows the existing equipment layout and identifies specific components requiring replacement, with annotated arrows and labels indicating work locations throughout the tank chamber and supporting pump systems.
