Deprest: A Name with History, A Mission to Impress

At Deprest, we're proud of our name — and everything it stands for. While we’ve occasionally heard that we could just as well be called "Impressed", our name remains firmly rooted in our origins. It was our founder, Armand Deprest, who started the company in 1936, and since then Deprest has grown into a respected name in the world of pressure vessels.

SAW welding at Deprest

At Deprest, we apply advanced welding techniques to guarantee the highest quality in the construction of storage tanks and pressure vessels.

One of these techniques is Submerged Arc Welding (SAW) – particularly well-suited for large and thick-walled constructions.

SAW provides:

• deep penetration and strong welds

• consistent and uniform quality

• high efficiency for large-scale projects

By combining modern technology with the expertise of our team, we deliver durable and safe solutions tailored to our customers’ needs.

Final assembly of a stainless steel pressure vessel

All components are designed and calculated according to international standards.

• Safety, durability, and precision are at the core of every vessel we build.

 Here, our team is installing a davited manhole cover – a hinged access point for safe inspection, cleaning, and maintenance.

The starting point of a new pressure vessel

Every vessel begins with its foundation. Here you see the base head with the supporting legs being assembled.

 At Deprest, many welds are done using automated welding systems to ensure consistency, precision, and strength. But not everything can be automated, some welds require the skill, flexibility, and experience of a qualified welder.

 From the very first weld, all work is carried out according to international pressure vessel standards, ensuring safety, durability, and long service life.
