Tank construction in tight spaces reduces plant downtime

Louise Smyth

Often we do not have the luxury of working within a spacious new build environment, existing plant structures need to be catered for, and that luxury will be further diminishing in the future.

In the world of large volume liquid storage and processing tanks, that can be a problem, literally a very big problem - that’s where Lipp’s automated spiral seam tank building system comes in.

Over the past year or two, as AMP 6 and the new TOTEX system have become embedded, the messages being sent from the water utility companies is that refurbishment, re-use and upgrade is the way forward. Whole life analysis of product performance has become critical in-terms of economic evaluation and is the preferable option over and above initial purchase cost, which includes any circumstances that involve complete replacement and/or new build.

In certain circumstances this means that components within an overall system will be replaced or upgraded rather than the complete system itself. This can be difficult enough with smaller components; when the components in question are very large, like water storage or process tanks on a waste water treatment plant, then the problems can be very challenging indeed.

Typically tank construction requires a lot of space around the tank for scaffolding, ancillary equipment and personnel, which simply may not be available if you are working within an existing, confined and operational processing plant.

In contrast, the Lipp spiral-seam tank construction system requires very little space for building and so is suitable for replacing, upgrading or expanding upon existing storage and processing plant capacity. Because the tanks are built from the ground upwards as a spiral, using Lipp’s automated construction process, most of the building work takes place at or close to ground level. Also, because the system needs minimal scaffolding work on the outside, the tanks can easily be built between existing processing and storage tanks, support frameworks and gantries - which would otherwise present real difficulties for older style bolted section tank solutions.

The Lipp double-fold system is the fastest and easiest technique for flexible construction of reliable containers and tanks within a customer’s existing operational location. The main characteristic of the tank building system are the transportable compact assembly devices, allowing the construction of tanks by steel bands from within the tank ground plan; a very effective method of building in challenging process environments. The highly automated production process permits a continuous variable size installation within a short time frame – and in a small space.
