Pharmaceutical chemistry

Within the pharmaceutical chemistry industry SRI is a respected manufacturer of reactors. Crucial for these type of pressure vessels is their internal and external finish. Usually we opt for internal electropolishing for reasons of cleanability and zero product adhesion. In our designs dead spots won’t be foud. Also, we often build our pharmaceutical chemistry vessels with a heating mantle (or half pipe coil) and insulated casing.

Meeting even the most strict cleanability requirements.

Concept and engineering

First off, we translated our customer’s requirements data sheets into a GA drawing. All requirements regarding sanitary design were included in the detailed design.Read more

As always when pressure vessels are involved, our engineers took various design codes into account. We submitted our drawings and calculations to the NOBO; also we coordinated PED Module H1 certification. In addition, also SSME with U-Stamp for the United States is an option./read]


Realization and development

Before starting production, our independent QC department draws up an ITP (inspection and test plan). Based on the ITP, we set up a PIM (pre-inspection meeting) with our customer.Read more

Construction and installation

Based on our various drawings SRI starts production. Parts are rolled, welded, precut and recut. During the entire manufacturing process, preventing parts damage is key. Read more


Service and maintenance

After approval by all parties involved, we lift the equipment according to an approved lifting plan and then transport it to our customer.
