The project in context
Technology in its operating context.
Refurbishment of a hydrochloric acid measuring tank in Rybitví included a new PP-H vessel, valves, a level gauge and installation connections. The vessel had a 1,200 mm internal diameter, a 2,000 mm cylindrical shell height and an 8 mm wall, with a documented workshop watertightness test.
Scope of work
- PP-H vessel: 1,200 mm internal diameter and 2,000 mm cylindrical shell height
- 8 mm wall thickness in the final delivery
- Two DN 50 and two DN 25 ball valves, plus one level gauge
- Piping connections, gaskets, installation and as-built documentation
New vessel and process connections
The supply renewed the hydrochloric acid measuring tank together with its local accessories. The manufacturing drawing specifies PP-H, an internal diameter of 1,200 mm and a cylindrical shell height of 2,000 mm. The final delivery specifies an 8 mm wall.
Connections include a DN 50 inlet and vent, a DN 65 overflow, a DN 50 outlet and two DN 25 level-gauge connections. The 2,000 mm height relates to the cylindrical shell; the drawing separately defines nozzle and connection interfaces for installation.
Valves, level indication and installation
The supply included two DN 50 ball valves, two DN 25 valves and one level gauge. It also covered connecting pipework, fasteners, gaskets, on-site handling, installation and as-built documentation.
The work linked vessel manufacture, accessory supply and installation at the existing process interfaces.
Watertightness test and acceptance
The manufacturing watertightness check used water filled to a height of 1,900 mm for 48 hours. The report records no measured loss after 24 or 48 hours and an acceptable result. This was a workshop watertightness test of the vessel itself.
The signed handover document subsequently confirms acceptance of the refurbished measuring tank and its suitability for continuous operation within the scope of the handed-over equipment.
Outcome
A measuring tank handed over with valves, level indication and installation connections, supported by the vessel’s manufacturing watertightness record.
