Construction & Piping

Founded in 1954

J. de Jonge Konstruktie & Pijpleidingen was founded in 1954 by the ambitious Jan de Jonge, Sr. The core activities of this fledgling company included construction and piping for small projects in the Rotterdam harbor. Today, the expertise of Construction & Piping is centered around the construction of mechanically engineered structures, skids, special products, equipment and piggable piping systems. One of the distinguishing features of this department is its ability to quickly respond to urgent (stop-gap) situations.

Mechanical construction & Piping systems

We specialize in the manufacturing of mechanical constructions and the construction of piping systems. We handle our assignments within the agreed delivery time and within all quality requirements. Of course all other necessities as occupational health, environment, and safety requirements hold a first priority in all our operations. Besides daily on-site maintenance, we also provide new construction and renovation of charging stations, pump platforms, tank pits, etc.

Construction & Piping


A skid consists of a processing installation mounted on a steel frame. This can range from heat exchangers and tanks up to full filtration and metering systems. The skids are always constructed, installed and tested to meet specific client requirements. With regards to the many disciplines within J. de Jonge flowsystems you can rely on a satisfactory collaboration. Our waterside location provides for a major advantage.

Construction & Piping

Piggable piping systems

If you have a need for efficient and flexible multi-product transport through a single pipeline without contamination, a "piggable" piping system provides for an optimal solution. In principle, pigging is used to clean a pipe system after transporting a product. After this cleaning, the pipe can be used again for another product. With a closed system it is possible to make alternating connections between different devices in an integrated production process. Piggable pipe systems can be delivered in both open as closed versions.

Construction & Piping


Since 1954, we have established a reputation of craftsmanship, technical innovation and high quality in the world of strainers and other specialty products. Nowadays, we design and build products for the most prevalent industries and we are one of the leading suppliers in the Dutch market when it comes to innovation and material selection. Due to solid particles in process streams, a fair chance exists that your process equipment (pumps, compressors, control valves, etc.) may become damaged. This results in unnecessary downtime of your equipment and leads to costly repairs or, even worse, could compromize the continuity of your production. We make and supply a range of Cone, Y, and Bucket strainers that cover a wide variety of applications, as well as special designs in order to resist more extreme conditions such as pressure fluctuations and water hammer.




The flow launchers are custom designed and developed for each client, they are used to maintain and clean your piggable piping to assure that no residue remains on the lead. At the end of each product transport, it is possible to clean the entire pipeline by means of a pig. This not only works faster than draining, but is also more effective because the residue is completely pigged away. LAUNCHER & RECEIVER

Our flow launchers are engineered in such a way that changing and maintaining pigs is reduced to a simple operation.

Loading Technology

Founded in 1987

The first step to multiplication of business units begins with the founding of J. de Jonge Verladingstechnieken B.V. in 1987. Main activities include maintenance, manufacturing and the overhaul of loading/unloading stations. Nowadays, the Loading Technology division has grown out to become an industry leader in loading and unloading facilities for ships, trucks, and wagons. We provide for custom design, construction, maintenance, repair, and modification for each client specific application. We distinguish ourselves by brand-independent maintenance and a 24/7 call-out service.

"Industry leader in service, repair, and overhaul of marine, truck, and rail loading arms"

Loading Technology

Revision & Maintenance

Marine loading arms are designed for the transporation of fluids from vessel to shore and vice versa. Marine loading arms are increasingly preferred for the handling of fluids and gases. Naturally, your marine loading arms need to be kept in an optimal condition. The Loading Technology department provides for brand-independent maintenance and a 24/7 call-out service, thus assuring that your projects can be brought to a successful conclusion, while your equipment remains fully operational.

Folding Stairs & Fall Protection

Folding stairs are used whenever operators need a simple and safe way to enter a truck or wagon. We build stairs in compliance with the highest quality standards. Several safety features ensure that people cannot get their hands and / or feet caught into something. Everything is built and constructed according to the latest applicable standards. As most of the top loading of trucks and railroad cars are made customly, many different configurations can be made. From the first basic design, J. de Jonge flowsystems is the right partner to advise about the most appropriate solution for you.

Loading Technology


Loading Technology flow tower TM Constructing flow towers since 1979. If you ship multiple products that need to be loaded / unloaded, a flow tower or a hose tower is a good alternative to the traditional marine loading arm. The latest generation of 'Multi Purpose' tankers and new logistic flows, combined with the large variety of products to be pumped, require an innovative way to handle these products in as short a time as possible. Our flow towers are based on the operational requirements of our client. Therefore, they are designed for each specific appliance. The most important benefit of a flow tower is its shorter docking time.

Plug Systems

A leaking pipe in a heat exchanger is extremely bothersome. Plugging leaking pipes is a solution which has been used for years to prevent costly and lengthy repairs, such as to prevent retubing. The drawback of traditional plugs is that they may result in "uncontrolled" and dangerous situations. For example, consider a plug being blown off with great force due to pressure build-up. With certified mechanics, we can safely set and clear "controlled" and certified plugs in various designs, materials, and sizes for you. HES works exclusively with certified plugs and equipment.

We have been responsible for the engineering of the terminal and all its parts, supply, and installation of the piping, the construction of a Truck Loading Station, supply and installation of 3 new flow towers to be built, construction of 9 new storage tanks, and the construction of the E&I part. In July 2010, this EPC project was initiated by the prefabrication activities in our workshops. In August 2011, the on-site work was completed. In total, approximately 26,000 man hours were delivered. This equates to about 15.5 man years. Approximately 8 kilometers (4.97 miles) of pipeline and 3000 processed pipe fittings with an average diameter of 6 metric inches (5.51’’) were installed. Addtitional appendices were mounted on 1,100 units.

J. de Jonge flowsystems has completely overhauled the mechanical installation of the Gryphon FPSO. This FPSO (Floating, Production, Storage, Offloading) is a converted supertanker which directly connects oil and gas resources to the seabed via pipeline. The ship, the Gryphon A, is over 250 meters (273.40 yards) long. The installation process includes multiple systems, each of which needed to be overhauled. J. de Jonge flowsystems was chosen because of the long experience that the company has in petrochemicals, and by choosing J. de Jonge flowsystems as an overhaul partner, they chose a partner with multidisciplinary maintenance techniques, supported by an engineering department that can outsource itself. The total overhaul scope includes more than 60,000 man hours.
