In the autumn Deprest contributed to an artistic project, which consisted in an aluminium structure for a major show.
The structure involved one large central ring with a diameter of 8 metres and 4 hinged metal legs.
Watch the video to get a good feel of what went on in our workshop. It also demonstrates how the articulations of the structure were tested.

Another pressure vessel has left the building
It’s not suprising to see a pressure vessel leaving Deprest. We at Deprest are specialized in pressure vessel. Each week some vessels – large or small – leave the site. Our pressure vessels are made in steel, stainless steel and special alloys. We elaborate and follow projects from A to Z, inclusive technical calculations, design, testing, complete execution, and the testing and follow-up of the necessary inspections.

Deprest has spent several years installing cutting-edge technology and equipment.
Ever since 2013 when we added a new building, we have equipped ourselves with the latest technology in the areas of cutting, rolling and welding, and our new building has even been extended because it was too small. Notwithstanding all this new technology, we wouldn’t have gotten where we are without skilled professionals.

Deprest has invested in a new heavy-duty profile bending machine
In the context of the workshop expansion, Deprest has invested in a new heavy-duty profile bending machine, of the Sahinler HPK 100 type. This new bending machine allows us to significantly expand our capabilities.
This machine will be used for our own production, but also for subcontracting projects.

New PED regulation
After more than 10 years, a new Pressure Equipment Directive (PED) recently came into force, PED 2014/68/EU, which replaces the former 97/23/EU.
This applies to all pressure vessels which are sold on the European market after 19/07/2016. It goes without saying that Deprest will apply the new regulation.
It would take us too long to explain all the differences here, but feel free to contact us should you have any questions.

New! Plasma keyhole welding installation broadens Deprest technical range
It’s operational! Our new plasma keyhole welding installation!
Once our people were trained, they tried it out in real-life production conditions with very good results, for both butt welds and fillet welds.
The installation offers opportunities for plasma keyhole welding as well as TIG welding.

Recent realisation: pressure vessel with halfpipe
The attached photos show a recently manufactured pressure vessel consisting of boiler steel plate with halfpipe. Part of the vessel was assembled using the submerged arc welding process, while the remainder was manually welded.
A half coil jacket is made by welding a half pipe around the vessel. A plug flow with a heat transfer fluid passes through this pipe, allowing for a fast and uniform regulation of the vessel temperature.

Stereo or simultaneous welding is a method regularly used at Deprest. As the word suggests, this is a method where 2 welders weld a sheet or pipe on both sides at the same time in order to achieve a perfect lap. The difficulty here is to have the welders welding at exactly the same speed, so they need to be adjusted to match each other perfectly.

Halfpipe - halfcoil projects
The so-called “half pipe” or “half coil” techniques are among the methods used to bring heat to a vessel. They consist of half pipes in the form of a spiral welded to the vessel so the hot water flowing through these half pipes can heat the vessel. The half pipe method is regularly used at Deprest in addition to the “bain marie” method (for double jacketed or, more often, triple-jackted vessels)

In the spotlight: HD plasma table - cutting of heads
Our HD (High Definition) plasma table cuts plates, pipes and heads.
We would like to use this little article to highlight plasma cutting of dished heads. The enclosed photos speak for themselves - a lot can be achieved with an endless rotating 3D head. Not only are the holes in the head cut in the right place, but it also possible to include the necessary engraving (e.g. for identifying pieces) and the correct fusion edge.
