Siebec's Solutions for the Galvanizing Industry
SIEBEC provides solutions for the galvanizing industry to improve repeatability, reproducibility of quality, extend the life of the chemistry and improve the speed of the process.
We principally offers three tried and tested technologies for the galvanizing industry:
CASE STUDY.
Our customer has a 60 m3 volume flux tank running at 50 - 60°C.
THE CHALLENGE
Unfortunately, like many galvanisers, they were experiencing processing quality issues related to the variation in iron concentration within the flux process.
Hot-dip galvanizing pre-treatment requires the mainteance of two critical parameters. One being the oxidisation of iron (Fe2? to Fe3?) and the second, iron concentration within the flux solution that should be maintained below 1 g/l.?
THE SOLUTION
We then supplied and fitted 3 x P51-A30 filters, each fitted with 4 L-TECH 50 μm pleated cartridges, allowing iron particles to be extracted from the 60 m3 flux tank. Thanks to our designed solution, our customer now maintains the iron concentration in the flux process below the desired 1 g/l and no longer experiences the quality problems they had been experiencing prior.

THE RESULT
Happy customer – the solution has proven to be cost effective as the filter media is not only very quick and easy to clean which minimising waste but the L-TECH re-usable cartridges only need to be replaced every 4 -6 months.
PUSH-PULL agitation - Pumped agitation of HCL Pickle tank.
SIEBEC developed and designed this technique specifically to create a uniform, evenly distributed laminar flow of the pickle acid across the entire surface of the parts anywhere within the tank.
This system has the additional benefit of increasing the effectiveness of the pickling solution during the colder months - when cold, longer pickling immersion times are required to attain the same reaction.
Alternative technologies are the addition of either air agitation or solution heating however both of these have an adverse impact on the environment and the fabric of the building.
Fitting a conventional Eductors system to achieve the same results is problematic as anything at the base of a large acid pickle tank is at high risk of being caught by the work and dragged out of the tank.
Additionally, PUSH-PULL system demand significantly smaller pumps and have proven to be an efficient and a robust solution for pickling applications.?
Benefits of the PUSH-PULL system
Oil removal of floating oils using a coalescer to skim off the surface of the degreasing tank. The benefits of removing the oil are that the degreasing solution will usually last longer and the oil is not dragged by the work down the line into other process tanks.?
