EGGA ENVIRONMENTAL & SAFETY

Because the EN1090-2 is going into revision and high strength steel is becoming part of it, it means that we have to ask what the risks are regarding galvanizing. Discussions on this have already started in 2011/2012 but there is now much more work on it. There are 2 main questions here:

1. Is there a greater chance of Cracking?

2. And what is the effect of process heat on the properties of the steel?

The results of the discussions and possible practical situations will have to be taken into account in the renewal of the ISO 14713-2. Studies of properties of Hardox and Domex steels showed that they gave no loss of mechanical properties when heated and cooled.

EGGA will seek a consultant on steelmaking to be further informed. There is no expert in this field in EGGA’s network. The re-use of galvanized steel was also discussed and this will be taken up within the working group. One way of doing this is to draw up a protocol for inspecting the usability of galvanized steel after its first use.

If you would like any information on the planning of standards for this half year, we can send you the Excel sheet on request.

The BREF came up briefly and the discussion of fossil-free energy sources. In time we will have to deal with it. Some aspects of the BREF involve “fine-tuning.” Expect the BAT conclusions to be implemented in the 4th quarter of 2022. If you are going to build new, keep in mind that the new BAT will apply then. For existing installations it is also important to realize that from the introduction conformity may be required by the competent authority. By 2026 at the latest, the rules will also apply to existing installations.

With regard to lead and the permitted amount, there is not really anything to report other than that there are question marks about putting solid lead and lead powder under the same denominator and about how serious the exposure to them is. I gathered from an IZA consultation that in the meantime, instead of the (M-) factor of 1000, the factor of 100 would apply. The goal is that there will be no distinction between the various metals now under scrutiny and that a postponement is desired until 2023 when info on Copper and Silver becomes known.

Seveso and Zinc ammonium chloride

This discussion was initiated by Italy and it appears that it concerned 1 company. Meanwhile, no more inquiries are coming in to this company which also fell below the thresholds due to lower production. The company mentioned in their statement the number 0.99 instead of the requirement of maximum 1; it is therefore below it. Jelle informed the meeting that there may well be locations that end up above the volumes mentioned in the Seveso. So it may well be that the fire is rekindled elsewhere.

MEFIAG Filters & Pumps has been producing filters and pumps for the galvanising industry since 1953. What started as a small factory in Loosdrecht has grown into a fully-fledged production company in Heerenveen, the Netherlands, with assembly facilities in China and America. MEFIAG is now recognised by leading companies in more than 50 countries as the supplier of filters and pumps.

MEFIAG is a manufacturer of plastic, stainless steel and steel-clad filters. Our products are mainly used in the galvanising and anodising industry (e.g. automotive, construction, sanitary fittings and furniture) and are increasingly finding their way into the PCB (printed circuit board) and chemical industries.

A long service life and high quality are our standard. In order to guarantee this, we choose the optimum housing diameter between thermoplastic or steel rubber housings. Throughout the years, MEFIAG has innovated in the areas of user-friendliness and safety.

For example, filters are often supplemented by an inlet tank. This is particularly practical for adding a filter aid, active carbon treatment or for pumping out the filter housing. The exchange package has also made its appearance. This enables short downtimes during cleaning and reduces the chance of errors under time pressure.

Our standard filter systems are in most cases an optimal solution for the filtration of your processes, are the end result of years of development and offer you the highest quality at a competitive price. MEFIAG has a controllable production process and a balanced stock management. Matters that offer long-term stability for both you and MEFIAG; a MEFIAG filter system that is 25 years old is the rule rather than the exception! In 10 or 15 years, you want to be sure that the parts for your filter pumps will still be available.

In addition, we do not want to lose sight of your specific requirements. Our engineers will be happy to work with you and design a tailor-made solution.
