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.

Construction & Piping

Skids

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

Products

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.

BUCKET-TYPE STRAINERS

CONE-TYPE STRAINERS

Y-TYPE STRAINERS

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.
