Cutting edge, automated pipe galvanising plant By Ermes Moroni, general manager and founder, Gimeco Impianti Srl, Italy

visualising the overall energy balance with a dedicated tool in the software suite. Fine control over process parameters becomes a key to quality and profitability in the galvanising bath. A dipping system with vertical screws is coupled with automatic single or twin pipe pick-up hooks, offering a good degree of freedom in tuning key factors. Pipes are forced to immerse, slowly rotating for better coating and draining. The first-in-first-out system is the best way to determine exact time of transit in zinc, so that given a certain product diameter or surface quality, each pipe will be absolutely consistent in final finish. An outside zinc wiping system and inside zinc blowing system with protruding mandrel and flying nozzle offer very high surface quality and very low noise impact.

the process with overhead cranes, fully controlled by dedicated software. Gimeco’s plants also feature full au- tomatic chemical pre-treatment, con- sisting of an entirely segregated tunnel enclosure to control the acid vapour diffusion. While this ensures protection for workers, it also protects the building and crane equipment. On top of that, automatic “recipes” can differentiate chemical pre-treatment times, adjusting to variable features of different pipes. Stats on chemical consumption are also quickly summarised by dedicated software functions. As an additional op- tion to waste management optimisation, Gimeco supplies a spent acid full regeneration system to convert the by- product into useful fertiliser. A similar approach to energy and waste efficiency is taken in the high efficiency infrared drier, which pre-heats the pipes before entering into the liquid zinc. Infrared is combined with heat recovery from the galvanising furnace,

3700+ Measuring Systems in Use Worldwide 650+ Customers in 60+ Countries HOW do you keep your industrial cost down and ensure that your quality standard is up to par with the strict requirements of today’s market? Very often, there is one simple answer to this question: automation. Traditionally considered less applicable to general hot dip galvanising, automation is extremely proficient in standardised products, such as pipes. In times of thinner profit margins, having the whole process under control, while making sure the final quality is consistent, has become mandatory. In 40 years of activity, Gimeco has established itself as a well-known Italian engineering and manufacturing company dedicated to the industry of pipe finishing and hot dip galvanising. Gimeco now engineers and delivers complete lines for pipes finishing: hot dip galvanising, surface finishing, pickling, phosphating, straightening, chamfering and threading. Pipe bundles up to five tons each are automatically transported through
