Our state-of-the-art production equipment and our enthusiastic team of experienced professionals are at your disposal to help turn your projects into a reality. Any projects? Contact us.
New investments in 2016
The workshop built in 2013 had become too small and was expanded by 1700 m2 in 2016, to be completed around the new year 2017. The new extension is suitable for the vertical construction of vessels and is also equipped with a new pickling hall. As regards machinery, too, new investments were made: among other things, the new Plasma Keyhole installation is the perfect complement to the impressive investment programme implemented in 2013.
Recent technology and enthusiastic professionals
At Deprest, all major production equipment dates from 2013 or later. Your projects are therefore executed with the latest technology, with a positive impact on quality. But the most important thing is still the knowledge and experience of Deprest and our people. Deprest boasts 80 years of experience, and a number of experts from G&G International and Inalco who also joined our ranks recently.

Our trump cards
- Use of most recent technology
- A team of experienced persons
- Vicinity of the port of Antwerp and hence the possibility to carry exceptional loads both by road and water networks
- Focus on quality (separate stainless steel processing, operating to various standards)
- The flexibility and drive that characterize SMEs
The latest technology and enthusiastic specialists
All major machines in the Deprest site date from 2013 or later, meaning that your projects are being executed with the aid of cutting-edge technology, which results in better quality products. But most significant are still the skills and the experience of Deprest and our employees. Deprest can look back on 80 years of experience, and on the recent reinforcement with experts coming from G&G International and Inalco.
Transport by ship or truck
The location of Deprest is particularly suited to exceptional transport by ship or truck
Close to the highway and the port of Antwerp , Deprest can easily use exceptional transport. Deprest can rely on plenty of external partners for that purpose.
Deprest is located a few hundred metres from the River Scheldt in Temse, on the site of the former Boelwerf shipyard. The river is deep enough to allow the transport of any cargo size.
Deprest is equipped to produce pressure vessels up to 85 tons, with a maximum diameter of 8,5 metres (the size of our largest gate is 9m x 9m).
Deprest chooses quality:
- ISO certified according to ISO 9001:2008, as well as according to the ISO 3834-2/BS welding standard
- Structures work according to the various standards and codes
- Broad expertise with regard to calculation and design
- Practices separation of stainless steel and steel during production
- Works with state-of-the-art machinery
- And very competent, experienced people
- Extensive know-how in post-treatments and finishes
What can we do for you?
In our workshop, we manufacture pressure vessels and pressureless tanks in stainless steel, steel and other alloys, both large and small. We can also supply structures and semi-finished products.
Our extensive range of machinery allows us to manage almost everything ourselves. When it comes to welding especially, there is no lack of options.
Hence the question: how can we be of service to you?
Work in progress... Hydrotest of a pressure vessel
A hydrotest / hydro pressure test / hydrostatic test is among others a standard NDT (Non Destructive Test) and involves filling the pressure vessel with water to test for strength and leaks.

Deprest and sustainability
Sustainability is a key value at Deprest.
We naturally try to apply this value at company level like everyone else by, among other things
- generating our own energy as much as possible by means of solar panels
- limiting our energy consumption
- sorting our waste – in this respect Deprest is obviously fortunate with its waste flow, since most of our waste (metal scrap) is 100% recyclable.
In addition to these traditional ways of contributing to sustainability, the projects we work on are very often intended for sustainable projects. We regularly manufacture parts for wind farms, we make sump tanks for ships (where all waste is collected, while in the past it was simply dumped into the sea). As many of our tanks are used to make processes cleaner, we also contribute indirectly to a better, more sustainable world.
Filter Baskets in the spotlight
The purpose of this article is to put the production of industrial filters (which are often small pressure vessels) and more specifically associated filter baskets in the spotlight.
As a rule, these filter baskets need to be very sturdy given the flow rates, pressures (and the occasional less gentle treatment by technicians) they have to withstand. This means that, notably when assessing quotations, you should make sure that you are ‘comparing apples with apples’, so to speak.
The difference between a light and a sturdy basket version can, for example, determine whether it can be used for just 6 months or last for years.
Perfect welding in the spotlight
There is welding and... welding. Look closely at the welds in the attached photo: perfect work, isn’t it? Whether the process used is manual welding as shown in this photo, or submerged arc welding, plasma keyhole welding, automatic or semi-automatic welding – to name but a few – not only do our welds always look impeccable; various NDT testing methods such as RX, MT, and more, also confirm it.
How come Deprest’s welding is of such high quality?
A sump tank is a holding tank where all the waste produced at sea is collected. The waste that used to be simply discharged into the sea is now collected and brought ashore without polluting.
This sump tank is double walled (stainless steel and steel) and built according to standards EN12285-2 - ASME VIII - EN 1993-4.It also complies with finishing standard P3.
No, your eyes are not deceiving you: this tank has a diameter of 3200 mm and a length of 15500 mm.
