The chemical industry demands highly specific equipment requirements. SRI exceeds these requirements by means of the engineering, manufacturing and inspection of our pressure equipment. Among our delivery program for the chemical indystry are heat exchangers (shell & tube), air-cooled coolers, reactors, columns, pressure vessels and piping. We not only carry out projects for end customers, but also for EPC contractors.

State-of-the-art manufacturing equipment

SRI uses state-of-the-art production equipment such as submerged arc welding, orbital welding systems for pipe-tube plates and our CNC machining center. We have extensive experience with the various design codes and are certified for PED according to modules H and H1. Also, we are experts in translating customer specifications into the final design, where we include solutions such as wind loads and earthquake calculations if necessary. Because of the specific demands by the industry we pay attention to clear communication with our customers during the design and subsequent manufacturing process. SRI stands for fully customer-specific solutions. Our independent QC department plays a prominent role for the ITP’s schedules, take-offs and release notes. We deliver our end products with a complete manufacturing report (MR) as standard.

On-site assembly

We frequently assemble our equipment on-site by our own staff. This includes detailed digital site scanning. SRI specializes in stainless steel materials and high-quality alloys such as 316(L) stainless steel, (Super) Duplex, Inconel, Hastelloy and Titanium.

Concept and engineering

Right from the concept phase of any project, SRI is heavily involved in the design of devices in order to create the best solution in cooperation with our clients. Our main challenge is to use all possibilities within the assigned design codes and customer specifications. We also take care of the entire approval process. As a result of our experience we often manage to surpass our clients' expectations with well-thought-out...

For the production of chemical components, SRI has developed a high-pressure heat exchanger to replace the existing one. Our new version is made of Duplex material. To minimize any product adhesion the product end (pipe side) is polished. Additionally we polished the piping internally. During a short production pauze at our customer, we disconnected the existing item and installed the new one. Earlier, we carefully measured the old...
